Mason-Lite B-Vent Fireplace Options

June 9, 2015

When considering a gas-log fireplace for your home or business, look to Masonry Fireplace Industries (Mason-Lite).

Mason-Lite, a leader in pre-fabricated modular fireplace kits, offers an array of gas log fireplaces to meet your personal needs, starting with the B-Vent gas-burning series modular masonry firebox kit.

The concept of the B-vent fireplace, also known as atmospherically-vented, or natural-draft, grew out of the Environmental Protection Agency’s Clean Air Act laws regulating wood stoves, which first went into effect in 1988. Natural gas and propane fireplaces provide the benefits of a wood-burning fireplace, but with far lower emissions. As concerns for air quality increased, and rules, regulations and restrictions regarding wood-burning fireplaces became more prevalent, popularity in natural gas and propane fireplaces has grown.

Mason-Lite modular masonry gas fireplaces are designed for those who desire the convenience of a real fireplace for those special occasions, like dinner parties, and intimate gatherings with friends and family, but without the mess and hassle that comes with a wood-burning fireplace, and without having to collect and store stacks of firewood.

And with a Mason-Lite gas log fireplace, there’s no such thing as a “no-burn” restriction.

The Mason-Lite B-vent series of gas log systems offers an array of benefits and safety features. The B-vent system relies on a natural draft system and specially designed pipe to automatically carry combusted gases out of the home. Ventilation occurs naturally and doesn’t require electricity, thus improving safety.

Each unit is to be paired with a listed B-Vent chimney system, designed to protect both chimney and structure from fire and to be low-maintenance. We recommend chimney systems that meet UL 441 as well as UL 1777 requirements for residential factory-built, gas-burning chimneys.

Each Mason-Lite unit (MGFP39-MGFP49) comes with a standard 10-inch flue hole attaches to an anchor plate for your B-vent chimney system. Our MGFP43ST model comes with a standard 12 inch flue. B-vent chimney’s size makes it perfect for projects with reduced framing requirements.

Why go with a Mason-Lite B-vent system? For one, Mason-Lite’s combined 100-plus years of experience means we keep up to date on all local, state and federal requirements for safety and air quality protection. Our units meet EPA and current building codes for both indoor and outdoor construction. All Mason-Lite B-Vent fireplace systems are independently tested to pass the ANSI (American National Standards Institute) Z 21.50 gas fireplace safety standards when installed to manufacturer instructions for safe operation.

Mason-Lite B-Vent natural gas masonry fireplace systems provide the warm glow of a real wood fire. The fireplaces burn more cleanly, with lower outputs of carbon monoxide and other pollutants and particulate matter, than their wood-burning counterparts.

Mason-Lite also recognizes the added value of installing a gas fireplace in a new or existing home, and can customize your fireplace to give it an authentic look and feel of real wood. Our systems can be retro-fitted to fit your existing fireplace.

All Mason-Lite fireplaces kits are made in the U.S.A. Modular, pre-cast systems are light weight, which means lower shipping and handling costs and more affordable pricing. Because they are made of light-weight materials, Mason-Lite fireplaces are easy to install, and can be installed on multiple levels of the home or office with minimal reinforcement.

Mason-Lite offers three sizes – the 39-inch and 44-inch models offering 65,000 BTUs; and the 49-inch with an output of 80,000 BTUs. Mason-Lite B-vented series includes an RH Peterson “RealFyre” gas log set, designed to replicate the natural beauty of wood, with remote control.

Mason-Lite can also provide custom B-Vent Modular masonry fireplace for your special fireplace needs. Please visit for more information and a quote.

Mason-Lite recommends you always maintain a reliable carbon monoxide detector in the home or office, regardless of what type of fireplace you use.

Whatever questions you have, Mason-Lite has the answer.

PureBurn EPA Phase 2 Qualified Wood Burning Fireplace

April 7, 2015

Attention Mason-Lite Customers,

We are proud to announce that, with the use of our PUREBURN system, we have the cleanest burning Masonry Fireplace which exceeds the EPA Phase 2 qualifications. With air quality regulations becoming more and more restrictive we felt that we needed to produce a clean burning fireplace. That is exactly what we have done.

Our units surpassed the competition, releasing only 2.4 g/kg of particulates – the lowest test of any modular masonry fireplace to date. Our units work through a specially designed burner system that assists the word-burning process with (33,000 Btus) of natural gas or propane. With the assistance of our burner system your masonry fireplace will burn cleaner than ever before. Not to mention we have done it all without the use of a catalytic converter or glass doors that most of the competition requires.

Without requiring a catalytic converter, we reduce the cost per unit and also save time and money on installation charges. In addition, units with catalytic converters require mandatory maintenance and/or replacement over the life of the fireplace. With our PUREBURN units you are free of any problems associated with catalytic converters.

We displayed our unit at the 2015 HPBA show in Nashville. We received a lot of interest from customers in areas where EPA Phase 2 applies as well as areas that it is supposed to grow to be in. Currently we have tested our 44″ unit which will work with both the MFP44 and MFP 49. We are scheduled to test our remaining standard units this summer!

Below is our PUREBURN brochure link as well as a photo of the unit from the HPBA 2015 show.

Mason-Lite wood-burning models exceed EPA guidelines

When installing a new fireplace or replacing an existing one, the last thing homeowners want is to wade through the myriad bureaucratic levels of local, state, regional and federal clean air standards for home fireplace safety and emissions. Masonry Fireplace Industries, makers of Mason-Lite pre-cast modular masonry fireplace systems since 2005, utilizes more than 100 years of combined experience to take the worry out of fireplace installation and replacement. They understand the Environmental Protection Agency’s regulations, thus ensuring that your fireplace meets or exceeds EPA Phase 2 guidelines. After all, when you’re curled up in front of the fireplace enjoying the warmth and the crackling sounds of burning wood, the last thing on your mind is air quality.

Masonry Fireplace Industries strives to keep pace with changes in the industry and in emission standards and guidelines and have introduced the Pureburn line of home wood-burning units. All models meet or exceed EPA Phase 2 standards for residential fireplaces, giving you years of worry-free use. Our products are independently tested by the PFS Corporation testing agency to meet or exceed the EPA’s guidelines and National Fire Protection Association standards. Mason-Lite clean burning masonry fireplaces also meet UL 127 listed standards when installed according to manufacturer instructions.

Numerous studies have identified wood smoke as containing fine particles that can pose potentially serious public health risks. The Clean Air Act of 1970 has cut air pollution even as populations have risen. Yet today, according to the EPA, wood smoke from an estimated 12 million fireplaces and wood stoves continues to create significant health risks. In 2007 the EPA created the Burn Wise partnership program to ensure that cleaner outdoor wood-burning units are available to consumers. In October, 2008, the EPA moved to Phase 2 of the Burn Wise program and required that all residential wood-burning units installed after 1988 meet air quality guidelines.

Mason-Lite Pureburn fireplaces are designed to pass or surpass current air quality standards without the use of a catalytic converter, which can require mandatory annual maintenance and costly replacement during the life of the fireplace. Mason-Lite’s gas-assisted component eliminates the need for costly catalytic converters, thus reducing unit costs and installation time. In addition, Pureburn units have tested to 2.6 g/kg of emissions, placing them below voluntary EPA Phase 2 emission levels of 5.1 g/kg and making them more efficient that GreenTech Solutions Isokern units, once considered the industry gold standard.

The EPA Burn Wise program also emphasizes the importance of lowering emissions through education on proper wood-burning practices through simple changes to their fire-starting and -burning routines Suggestions include choosing the best types of wood for burning, burning only well-seasoned wood that has been split properly, maintaining consistently hot fires, and using proper wood storage practices. (Visit for more tips and ways to maintain a safe-burning fireplace.)

Homebuyers will pay extra for a fireplace, considered by the Hearth, Patio & Barbecue Association to be among the top three desired features requested by new home buyers (1). Mason-Lite Pureburn units can result in savings of up to 50 percent over hand-built masonry fireplaces. Mason-Lite concrete fire boxes are the lightest in in their class in terms of weight and highest in terms of heat-resistant strength. Because of our lightweight design, Mason-Lite Pureburn units can be installed throughout multi-level homes.

Mason-Lite fireplace systems can be installed indoors our outdoors and accommodate wood, natural gas and propane gas systems. We design our units with safety in mind and all of our systems comply with UL 127 and UL 103 chimney component standards for factory-built fireplaces installation. They also come with a 10-year limited warranty. Our easy, “no-mess installation” means faster completion time and results in lower installation costs.

Masonry Fireplace Industries will custom build units to your specifications. We also offer gas-burning fireplaces, vent-free fireplaces, fire pits, the Toscana wood-fired pizza oven, and masonry accessories. For more information on bringing the beauty and warmth of a clean-burning fireplace into your home or business, visit or call 800-345-7078. We can also be found at,, or follow us at

Product Update

August 20, 2014

Attention Mason-lite Customers,

Over the years we have had many inquiries pertaining to offering certain complementary products. We are excited to present some new additions to our Mason-Lite Price-list that we feel will really benefit the sales of our products.

First, We are proud to announce that our “Pure-Burn” EPA Phase II Fireplace is coming on to the market. Currently we are offering the burner and grate system to be retrofitted into our MFP44. For more information on this unit please contact us.

  Second, We have added additional products to our Accessories and Dampers. We have added the see-thru air kit (MFPST-AK) for both see-through units as well as custom units with square sides. We have added our new arch for use with the MFP63 (MFP-ARC63). We are also expanding our cast iron dampers to include all of our standard sizes (33″-63″). Note: The MFP-CC56 is a custom made damper. 

Third, We have added our both our Masonry Chimney Cap (MMC-14) as well as our Fire Ring Cap (MFR-CAP) to the second page. Our masonry chimney cap acts as a spark arrestor as well as a rain/debris shield for our masonry chimney systems. The fire ring cap was added because our Unfinished Fire Ring does not include a cap because the customer has the option of using their own finishing material.    

Lastly, We have added the Roof Radiation Shield (##DCA-RRS) as well as the Attic Insulation Shield (##DCA-IS) under the DuraChimney packages. We have found these to be very beneficial to the chimney systems.   

 These changes will take effect in September. Please contact us with any questions you may have about these changes.

New Brick for Brick Panels

June 11, 2014

Dear Mason-Lite Customer,

We have decided to change the brick we use for our firebrick panels. We have had a little trouble with blemishes in our old firebrick.

The new brick will not only have practically no blemishes but it is also a stronger brick. This will ensure an even higher quality of product than we are already supplying you. We chose the closest color to our old brick which is a gold. We have had a great response to the color so far. I have attached a photo of our old brick and our new brick for a visual. The best part is the price of the panels will not be effected by this change!

We will start shipping this new brick this week. Please note that we will not mix any old brick and new brick in your current or future orders.

New Brick                                                                                                                       Old Brick






Top 4 Reasons to Choose A Corner Wood Burning Fireplace.

June 3, 2014

A fireplace can be an appealing addition to any room, home, or business. However, some people find that a traditional, flat-front style fireplace does not meet their needs. As a result, more people are installing corner space-saving wood burning fireplaces in their dwellings or businesses.

Mason-Lite specializes in all sizes and styles of fireplaces, including smaller units that tuck neatly in a corner. Our team of fireplace experts can listen to your space needs and help you pick the right wood burning fireplace for your business or home.

We are always happy to learn from our readers.

  • What factors motivated you to choose a corner fireplace?
  • What are the advantages of a corner wood burning design?

Reason #1: Enjoy Fireplace Ambiance and Comfort Anywhere

Do you live in a condominium, narrow town house, or older home? In these dwellings, and many others, floor space is limited. If your rooms have a small footprint, you may think installing a wood burning fireplace is not a good option for you. However, a corner wood burning unit can fit comfortably in any vacant corner.

Even if you have large rooms, you can consider subdividing them into cozy seating or reading areas, accented with a corner fireplace. You can have all the furniture and floor space you need, while having the relaxing comfort of a crackling fire to warm your loved ones on cold days.

Reason #2 Save Floor Space

A traditional flat-front fireplace takes up a lot of floor and wall space. This style, while very classic, can limit your ability to add furniture or decorations to accent your room. A corner wood burning fireplace is the best option when space is a premium. It takes up very little wall space and does not project as far out into your room.

Before you build a corner-style fireplace, or any fireplace, you need to consider your room layout carefully. You need to contemplate more than just the size of the fireplace unit itself. Think about normal traffic flow through the room. Be sure your fireplace location is at least 36 inches from any combustible wall that lacks protection. If you add a wall protector, you may be able to reduce the clearance to 12 inches. Also, you should plan for a non-combustible hearth extension on the front and side of the unit. In addition, you might want to consider devoting space to wood and fire-tending tool storage for added convenience.

Reason #3 Add Style to Your Interior Design

Corner fireplaces are rapidly growing in popularity. Those with interior decorating flair recognize the value of space-saving wood burning corner fireplaces. A corner set up leaves more wall space open for furniture. They can also provide essential warmth to a room. Because of their compressed size, corner fireplaces can fit in more rooms—such as bathrooms and kitchens.

In many cases, homeowners want their wood burning corner fireplace to be the focal point of their room. In this scenario, adding a mantle or attractive surround can draw attention to a wood burning fireplace in any corner. Savvy home decorators suggest that homeowners can use lighting, artwork, or even an flat screen TV near a small corner fireplace to ensure it rises to focal point status.

Decorating experts recommend that homeowners consider furniture placement layout before installing wood burning fireplace in a corner. Creating a comfortable living space should be the paramount goal. You can achieve this by ensuring the furniture pieces you plan to use most to face the fireplace. Also, consider using area rugs and furniture groupings to match the angle of your wood burning corner fireplace. If you are working with a very small seating space, using lightweight or swivel chairs can create a corner conversation area near your wood burning fireplace that you can reconfigure with ease.

You can also use a corner fireplace to fill out empty spaces in a large room. In addition, if you have a awkward or unbalanced room architecture, a wood burning corner fireplace can help provide a grounded, balanced look.

Reason #4: Create an Inviting Business Environment

Wood burning fireplaces tucked in a corner are not only appealing for a home—they can be great for your business too. Whether a business owner has a professional office or a retail location, having a corner wood burning fireplace can provide a welcoming environment for clients. For example, since a fireplace conjures a home-like feeling, having a corner wood burning fireplace in a medical office can put patients at ease before appointments.

These days, fireplaces are often found in restaurants, since they help patrons relax and enjoy their meal. Wood burning corner fireplaces can also create a soothing mood in salons and other spaces. If you operate any type of business, think of the many benefits a corner wood burning fireplace can bring.

Spark Your Imagination

1If you have an empty corner in your home or business, a wood burning fireplace might be a good decorating choice.  Also, if you have an older model wood burning appliance, such as stove or fireplace, upgrading to a new model is advisable. As the United States Environmental Protection Agency notes, modern wood burning fireplaces are 50% more energy efficient and produce 70% less pollution than older models. Having a wood burning fireplace in your corner not only boosts your room aesthetics, it also makes good economic sense.

When shopping for a corner wood burning fireplace, you should seek top-quality advice. At Mason-Lite we have more than 100 years combined experience in the fireplace industry and can provide you with all the information you need. We are recognized as one of the top providers of modular fireplaces—including corner models.

If you already have a corner wood burning fireplace in your home or business, we would love to hear about your experience

Important Installation Update

February 3, 2014

We would like to take this time to announce some very important reminders about the installation of our fireplaces. We have very specific instructions in our manuals that pertain to not only the installation process but also the curing instructions following the installation. We understand that the dealer and/or the installer will not always be able to instruct the homeowner of the importance of the curing process. We have developed a label to be left inside of each unit after the installation for the eyes of the homeowner. This label explains the importance of the unit having 28 days to dry before being used. After which, 2 small fires are to be started before standard use. We have attached this label below with more information. Please contact us with any questions about this process and or the label.

Product Update

December 18, 2013

Dear Customers,

Here at Mason-Lite we strive to offer the best products possible for your masonry fireplace needs. To make that possible we are constantly improving our products. Recently we have made two such changes that we believe will benefit the use and installation process of our products.

The first change we have made is to our mortar. We decided to reformulate our mortar to offer the best quality for masonry fireplace installations. This new mixture meets and exceeds the ASTM C-199 rating for high-temperature mortar. ICC has recently updated their requirements for masonry fireplace installations to include this rating.

The second change that we have made is to our T-Bar that supports our lintel system. We have heard from our installers that the lintel length is slightly too long for a flush installation. We have decreased the length to make sure that every installation is flush, yet very well supported. Another change we have made to our T-Bars is the addition of metal lath to the top of the T-Bar. This helps bond the T-Bar to the lentil with our new and improved masonry mortar.

Both of these changes will be included in all units produced after January 1, 2014. We enjoy bringing you the best products possible and we encourage all of our customers to give us any feed back that will help us do so.
