FAQs
Why should I choose an all-masonry fireplace over a metal fireplace?

Masonry fireplaces offer numerous benefits over a metal fireplace including:

Are there disadvantages of using traditional brick & mortar fireplaces?

A few potential disadvantages of a traditional brick and mortar fireplace include:

How does the heating property of traditional masonry compare with that of FireRock?

Traditional brick and mortar can actually absorb heat from the fire as well as expand and contract with varying temperature demands. This fluctuation in the fireplace will wear down more quickly. FireRock products are ‘refractory’, meaning the heat is actually reflected back into the home and the product does not expand and contract, thus promoting greater durability.

Can any FireRock unit be installed inside?

Yes, all FireRock styles may be used inside. When choosing a fireplace unit for any indoor area that has a roofline, it is important to remember that you may not choose a unit from out Outside series. Please make your selection from our Conventional or Rumford series.

Can I install my own FireRock fireplace or chimney system?

Yes, one of FireRock’s strengths is the fact that our firebox and Solid Block Chimney system is interlocking and simple enough for a reasonably knowledgeable do-it-yourselfer. Manufacturer’s installation instructions must be followed.

Can I use FireRock fireplaces as a primary heat source for my home?

No, the FireRock fireplaces are not designed to serve as a primary heat source; rather the fireplace was expressly created as a supplemental source of heat.

Do FireRock fireplaces require a chimney?

Yes, our fireplaces do require a chimney. They must be installed with an approved class A metal chimney system with an approved damper. Except for our Vent-Free models, all FireRock fireplace systems require the use of a chimney. Most models accommodate your choice of metal or solid block chimney systems. LiteRock requires the use of a metal chimney.

Can a metal chimney be used on FireRock units?

Yes. FireRock recommends Simpson Dura Chimney II, a UL-103 compliant, air cooled chimney that is relatively inexpensive and easy to install. FireRock is a distributor for Simpson Dura Chimney II and has it available for your installation should you need it.

Can I vent FireRock fireplace directly out the back of the box?

No. FireRock vented units are specifically designed to vent vertically.

Does FireRock have code approvals of their units for installation inside and outside homes?

FireRock fireplaces are tested to UL 127 standards. FireRock is the only masonry component fireplace that has been tested and found compliant with UL-127 Outdoor standard.

Is FireRock branded mortar required for the installation of FireRock fireplaces and firepits?

Althrough there are alternative bonding agents available, FireRock adhesive mortar must be used in order to maintain compliance with UL-127 and ANSI-Z 21.50 testing, and to validate the manufacturer’s limited 20 years warranty.

Can a FireRock unit be installed on the second floor of my home?

Yes, the FireRock Vent-Free and LiteRock fireplaces has been developed specifically for multi-level applications.

What type of unique support is required for FireRock?

Most FireRock systems require the same type of support as a traditional brick and mortar fireplace and require a non-combustible base. If built over a basement or crawl space, this can be accomplished either using concrete blocks or steel columns supporting a newly poured concrete pad. If FireRock is being installed on an existing slab, it requires a twelve-inch footing.

Is the FireRock fireplace system guaranteed not to spill smoke?

No fireplace can be guaranteed not to experience smoke spillage under certain conditions. As these fireplaces are designed and tested for maximum performance, they will offset any exterior atmospheric conditions that may exist. Interior negative pressure can cause performance issues in extreme circumstances. Please consult local code and your builder about the use of an outside air kit.

Can my FireRock fireplace be made to have a taller opening?

Absolutely, if your design calls for a taller aspect ratio or an arched-front you may choose a FireRock Rumford firebox or just add a Height Extension Kit to our Conventional firebox. Â Be sure to discuss things like ceiling height, indoor air quality, and overall firebox opening size with your FireRock dealer.

Is there a maximum and/or minimum chimney height for FireRock?

Yes, 80′ maximum height and 18′ of chimney components minimum. Please check with local codes and sales representatives for outdoor application requirements.

Can stucco, brick or stone be directly applied to a FireRock fireplace or chimney system?

Yes. We recommend the material be scratch-coated or metal lathed prior to the finish application. Please consult your builder or finished application professional
