If your home meets all of the three criteria above, you must provide additional fresh air. Warning: If the area in which the heater may be operated is smaller than that defined as an unconfined space or if the building is of unusually tight construction, provide adequate combustion and Example of Large Room with 1/2 Wall divider. Figure 1 The following formula can be used to determine the maximum heater rating per the definition of unconfined space: (L1 + L2)FT x (W)FT x (H)FT Btu/Hr = x 1000 50 If the area in which the heater may be operated is smaller than that defined as an unconfined space, provide adequate combustion and ventilation air by one of the methods described in the National Fuel Gas Code, ANSI Z223.1, Section 5.3. Adhere to all codes, or in their absence, the latest edition of THE NATIONAL FUEL GAS CODE ANSI Z223.1 or NFPA54 which can be obtained from: American National Standards Institute National Fire Protection Association, Inc. 11 West 42nd St. Batterymarch Park New York, NY 10018 Quincy, MA 02269 CLEARANCES Minimum Dimensions For Solid Fuel Burning Fireplaces UL127 Factory Built Fireplaces (Figure 2) Model A B C D VFDR18 17" 12" 28" 17" VFDR24 23" 12" 30" 18" VFDR30 26" 12" 34" 20" The dimensions shown and defined in the fireplace manufacturer’s instructions are minimum clearances to maintain in installing this heater. Left and right clearances are determined when facing the front of the heater. Glass Doors Make sure that glass doors are open during all operations of the logset. The opening of the glass door frame should be the dimension used for the minimum front opening of the firebox. Figure 2 Follow these instructions to ensure safe installation. Failure to follow instructions exactly can create a fire hazard. 21565-3-0906 Page 7 CLEARANCES (continued) Sidewall & Ceiling Clearances (Figure 3) 18”,24”,30”Log41” 6” Non-Combustible Material Distance Requirements for Safe Installation 12" or more Non-combustible material Less than 12" Non-combustible material must be extended to at least 8" with the installation of the optional fireplace hood. If you cannot extend non-combustible material at least 8", you must operate heater with flue damper open. Figure 3 The sides of the fireplace opening must be 6" from any combustible wall. The ceiling must be at least 41" (for 18", 24" and 30" logs) from the fireplace opening. Mantel Clearances Without Hood (Figure 4) You must have non-combustible materials above the fireplace opening. Non-combustible material must extend at least 12" above fireplace opening. With sheet metal, you must have noncombustible material behind it. Heat resistant materials such as slate and marble must be at least 1/2" thick. Sheet metal should not be installed onto combustible material. 10” and less Mantel Mantel Clearances with Hood (Figure 5) You must have non-combustible materials above the fireplace opening. Non-combustible material must extend at least 8" above fireplace opening. With sheet metal, you must have non-combustible material behind it. Heat resistant materials such as slate and marble must be at least 1/2" thick. Sheet metal should not be installed onto combustible material. Example: A mantel may project from the wall a maximum of 2" at a minimum of 13-1/2" above the opening, and a maximum of 6" at a minimum of 15" above the opening. 8” Mantel 6” Mantel 4” Mantel 2” Mantel HEAT RESISTANT MATERIAL 8” WITH HOOD 14.25” 16.0” HOOD HEATER IN FIREPLACE OR FIREBOX 15.0” 13.5” 28” 12” HEATERINFIREPLACEORFIREBOXHEATRESISTANTMATERIAL12”WITHOUTHOOD Figure 5 If your installation does not meet the above minimum clearances, you must proceed to one of the following steps: • Operate the heater with the flue damper open. See page 10 for Installing as a Vented Appliance. • Raise the mantel to the proper height. • Remove the mantel. Floor Clearance (Figure 6) If installing heater at floor level, the minimum distance to combustibles is “0” inches. Figure 4 If your installation does not meet the above clearances, you must proceed to one of the following steps: • Use a hood • Operate the heater with flue damper open. See page 10 for Installing as a Vented Appliance. • Raise the mantel to the proper height. • Remove the mantel.
