18" Model: Noncombustible material OK. No hood accessory needed. Less than 8" Noncombustible material must be extended to at least 8". See Between 8" and 12",above. If you cannot extend material, you must operate heater with flue damper open. Heat Resistant Material (A) Figure 5 - Heat Resistant Material (Slate, Marble, Tile, etc.) Above Fireplace 8 103425 OWNER’S MANUAL INSTALLATION Continued MANTEL CLEARANCES In addition to meeting noncombustible material clearances, you must also meet required clearances between fireplace opening and mantel shelf. If you do not meet the clearances listed below, you will need a hood. Determining Minimum Mantel Clearance If you meet minimum clearance between mantel shelf and top of fireplace opening, a hood is not required (see Figure 6). Determining Minimum Mantel Clearance When Using a Hood If minimum clearances in Figure 6 are not met, you must have a hood. When using a hood there are still certain minimum mantel clearances required. Follow minimum clearances shown in Figure 7 when using hood. NOTICE: If your installation does not meet the minimum clearances shown, you must do one of the following: • operate the logs only with the flue damper open • raise the mantel to an acceptable height • remove the mantel FLOOR CLEARANCES A. If installing appliance on the floor level, you must maintain the minimum distance of 14" to combustibles (see Figure 8). B. If combustible materials are less than 14" from the fireplace, you must install appliance at least 5" above the combustible flooring (see Figure 9).

If your heater is a manually controlled model, you may use this heater as a vented product. There are three reasons for operating your heater in the vented mode. 1. The fireplace does not meet the clearance to combustibles requirements for vent-free operation. 2. State or local codes do not permit vent- free operation. 3. You prefer vented operation. If reasons number 1 or 2 above apply to you, you must permanently open chimney flue damper. You must install the damper clamp accessory (to order, see Accessories, page 28). This will insure vented operation (see Figure 10). The damper clamp will keep damper open. Installation instructions are included with clamp accessory. See chart below for minimum permanent flue opening you must provide. Attach damper clamp so the minimum permanent flue opening will be maintained at all times. Chimney Height (ft.) Minimum Permanent Flue Opening (sq. ins.) 6' to 15' 15' to 30' 39 sq. inches 29 sq. inches Area of Various Standard Round Flues Diameter (ins.) Area (sq. ins.) 5" 6" 7" 8" 20 sq. inches 29 sq. inches 39 sq. inches 51 sq. inches INSTALLING HEATER BASE ASSEMBLY WARNING: You must secure this heater to fireplace floor. If not, heater will move when you adjust controls. Moving heater may cause a gas leak. WARNING: If installing in a sunken fireplace, special care is needed. You must raise the fireplace floor to allow access to heater control panel. This will insure adequate air flow and guard against sooting. Raise fireplace floor with noncombustible material. Make sure material is secure. CAUTION: Do not pick up heater base assembly by burners. This could damage heater. Only handle base assembly by grates. CAUTION: Do not remove the metal data plates attached to the heater base assembly. The data plates contain important warranty information. IMPORTANT:Make sure the heater burners are level. If heater is not level, heater will not work properly. For thermostat models, avoid damage to thermostat bulb. Avoid nicks or sharp bends in thermostat bulb wire. Keep thermostat bulb in mounting bracket.
