Vent Free Fireplaces

August 8, 2017

Vent Free fireplaces are growing in popularity across the United States. Just some of the advantages of a Mason-Lite Vent Free fireplace include:

    • No chimney expense
    • Ability to add a fireplace in areas that vented fireplaces would not allow (ex. Below a window)
    • Reduced BTU expenditure (less gas usage=lower monthly gas bill)
    • More radiant heat in your living space
    • Reduced installation time to its’ wood burning fireplace equivalent (under two hours)
    • Outdoor fireplace applications allowing for an unobstructed view

The U.S. Fireplace regulations are constantly changing by state, as well as by city. Be sure to check your local building codes to confirm the proper, safe and legal installation for a Vent Free Fireplace in your area.

Mason-Lite designed our Vent Free fireboxes to have a small dome above the opening to give the illusion of a chimney above the unit. This design is beneficial for fireplaces with a raised hearth and gives you the negative space that a standard vented fireplace unit would show. For those who are very short on space we do offer a flat top version as well.

Please see our attached brochure for more information on Mason-Lite Vent Free Fireplaces.

2017 Mason-Lite Photo Contest

May 11, 2017

The wait is over and the results are in! The winner of the 2017 Mason-Lite photo contest is Western Fireplace Supply in Avon, CO. Western Fireplace Supply installed the beautiful custom Mason-lite see through fireplace shown below. These photos show how versatile custom Mason-Lite fireplaces are. The fixed glass on the back side of the see through fireplace allows the fireplace to function as a single sided fireplace in regards to the draw/ draft of the fireplace. In adding this fixed glass the venting required for the unit is drastically reduced. We would like to thank Western Fireplace Supply again for their great installation of this unit and for providing this great photo. We would also like to thank all other submissions for this years contest. We will be posting all of this years entries in our gallery page at shortly. We strive to show our product in finished form for our customers and we could not do that without the help of our trusted dealers and distributors.

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.

For more questions regarding which fireplace is right for you, call 800-345-7078, visit our website at, or find us on Facebook.

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.
