Page 4: Important Safety Information
For safety information regarding the operation of this fireplace, see pages 31-33. The FireRock Rumford fireplace is a modular system designed to be assembled in field using FireRock Adhesive Mortar. Each component is designed for a specific part of the firebox, smoke chamber, and flue design, and therefore only one means of assembly is possible. -

Page 6: Intended Use Statement
The fireplaces and chimney system are tested and listed by Intertek Testing Service to UL 127 and UL 103. The FireRock fireplace is designed to burn wood, gas, or coal. Use solid wood, processed solid fuel fire logs, natural gas, propane, or coal fuel only. - Page 7 The FireRock Rumford fireplace is approved for Indoor and Outdoor use. Maintain stated clearance to combustibles for indoor and outdoor use.
-
Page 8: Installation Considerations
Avoid placing a fireplace in an area near tall trees or buildings that can reduce air flow pressure and/or produce down drafts. FireRock Products, LLC does not warrant drafting and is not responsible for it. Refer to page 24 for more information on using an outside air kit with a FireRock pre-engineered masonry fireplace kit. B. TERMINATIONS The termination of the chimney above the roof must extend at least 3’... - Page 9 E. LOG LIGHTER A log lighter can be used with your FireRock fireplace as either a flush mount (installed before the firebrick) or top mount. FireRock recommends the log lighter be installed by a professional plumber. See manufacturer’s instructions for directions on how to install.

53” 59” The numbers listed are the framing dimensions recommended by FireRock, which add ½” of air space to the required clearances. Always maintain the stated minimum clearance to combustibles for this unit. Failure to maintain stated minimum clearance to combustibles on page 12 may result in a fire or explosion, causing property damage, personal injury, or loss of life. -
Page 14: Fireplace Installation
It is the responsibility of the general contractor to ensure adequate foundations. NOTE: Use of the FireRock base plate is optional for either of the above foundation types (concrete slab or concrete pad). FireRock fireplaces can be installed directly on a combustible floor or a limited load-bearing floor using our LiteRock system. -
Page 15: Mixing And Applying Mortar
FIREPLACE INSTALLATION STEP 2: MIXING AND APPLYING MORTAR FIREROCK ADHESIVE MORTAR FireRock Adhesive Mortar must be used when building the FireRock fireplace for your FireRock warranty to be valid. Use of other mortar will void your FireRock warranty This mortar is available from your FireRock dealer or distributor. -
Page 16: Firebox Assembly
FIREPLACE INSTALLATION STEP 3: FIREBOX ASSEMBLY BASE PLATE The base plate must be placed on a level noncombustible surface. It is very important that your base plate be square to the room, properly centered, and level. Mark out the FIGURE 6.1 position of the base plate on the supporting floor system. - Page 17 LEVELING AND ALIGNING COMPONENTS It is important that each course of the firebox is level and flush with adjoining components. FireRock mortar is not intended to create a mortar joint of any thickness for leveling purposes. Leveling and alignment adjustments should be made by the use of small shims.

Page 18: Throat And Damper Assembly
A piece of angled steel (2” x 2” x ¼” thick) has been provided with your FireRock fireplace kit. The length of FIGURE 7.1 this angled steel piece corresponds with the overall width ASSEMBLED THROAT of your firebox model. -
Page 19: Smoke Chamber Assembly
FIREPLACE INSTALLATION STEP 5: SMOKE CHAMBER ASSEMBLY SMOKE CHAMBER The smoke chamber components can only be positioned one way. The fronts and backs are identical above the damper. Remember to completely cover each component with mortar 1/2” - 1” thick where each edge of each component will lie or butt up against another component. -
Page 20: Chimney Assembly
FIREPLACE INSTALLATION STEP 6: CHIMNEY ASSEMBLY SOLID BLOCK CHIMNEY FireRock Solid Block Chimney (Figure 9.1) may be installed from this point. Completely cover each chimney block component with 1” of mortar, resulting in a 1/16” - 1/8” joint. “Butter” all joints to give a smooth appearance and ensure a leak-free joint. - Page 21 FIREPLACE INSTALLATION STEP 6: CHIMNEY ASSEMBLY (CONTINUED) OFFSET BLOCKS Each offset block provides a maximum offset of 2 5/8”. Offset direction may be left, right, back, or in a spiral pattern for “twisting” flues (see Figure 9.4). Completely cover each offset block component with 1” of mortar, resulting in a 1/16”...

Page 22: Firebrick Installation
(Figure 10.3). FireRock makes no claims as to the performance of firebrick or firebrick mortars except those manufactured by FireRock. It is typical for heat stress cracks to appear in the firebricks after FULLY BRICKED FIREBOX use. -
Page 23: Brick Flange
BRICK FLANGE The FireRock Brick Flange (Figure 11.1) is a component that allows a true brick or stone veneer above the roofline (maximum 20 vertical feet of standard brick or equivalent). Most local building codes do not allow masonry to be supported by combustible material. Our brick flange is designed to carry the weight of a brick or stone veneer only where you see it. -
Page 24: Outside Air Kit
OUTSIDE AIR KIT INSTALLATION Outside air kits are an optional accessory that can be added to a FireRock fireplace to supplement combustion air. Outside air kits should be installed and used in accordance with requirements of the standard for fireplaces under national code NFPA 211. Follow manufacturer’s instructions for installation instructions and refer to local building code for proper sizing;... -
Page 25: Typical Gypsum Board Application
TYPICAL GYPSUM BOARD APPLICATION This fireplace is designed to be installed so a 3” ledge is left on top of the radius throat front. This ledge allows space for a framing header to maintain the required 1” clearance and at the same time align flush with the room face of the firebox. Failure to maintain stated minimum clearance to combustibles on page 12 may result in a fire or explosion, causing property damage, personal injury, or loss of life. -

Page 27: Metal Chimney Installation
METAL CHIMNEY INSTALLATION Any metal chimney that carries a UL 103 compliance designation may be used with your FireRock fireplace and chimney system. A conversion adapter must be available from the metal chimney manufacturer and all necessary components, including, but not limited to, firestops, wall spacers, and insulating parts, must be utilized as required by the manufacturer. -
Page 28: Literock Installation Method
LITEROCK INSTALLATION METHOD The FireRock LiteRock system is an installation method that allows our wood burning fireplace to be installed directly onto a combustible surface, typically without additional structural support. Before installing onto the combustible floor system, it is important that the building contractor has verified independently that the floor system is able to withstand the weight of the installation, including the chimney. - Page 29 Refer to pages 17-19. The FireRock base plate is mandatory for the LiteRock Installation Method. Failure to use a base plate with this installation method may result in a fire or explosion, causing property damage, personal injury, or loss of life.
- Page 30 (Figure 16.6). All materials that abut the fireplace or riser material must be noncombustible. The FireRock base plate is mandatory for the LiteRock Installation Method. Failure to use a base plate with this installation method may result in a fire or explosion, causing property damage, personal injury, or loss of life.

Page 31: Operating Instructions
OPERATING INSTRUCTIONS This section of the manual is to help you get maximum efficiency and maximum smoke (particulate) reduction from your FireRock fireplace. If you experience any difficulty or have any questions concerning your fireplace, contact your dealer/distributor or FireRock’s Technical Support Desk (888.876.1025). - Page 32 USING YOUR FIREPLACE FireRock recommends a log grate be used in your fireplace for maximum performance. The use of andirons is acceptable. Use solid wood, processed solid fuel fire logs, natural gas, propane, or coal fuel only. The manufacturer’s recommendation for peak performance is to burn seasoned hardwood (wood that has been cut and dry for 6 –...
- Page 33 Overfiring, abusive burning, or mistreatment of the fireplace unit can cause permanent damage to the unit and will invalidate your FireRock warranty. Building fires using materials other than those detailed on pages 31-33 or loading the fireplace beyond its maximum load constitutes overfiring.
