Mantel Clearances for Insert Installation

If there is a mantel above masonry fireplace, you must meet minimum clearance between mantel shelf and top of fireplace opening (see Figure 12).

NOTICE: Surface temperatures of adjacent walls and mantels become hot during operation. Walls and mantels above the firebox may become hot to the touch. If installed properly, these temperatures meet the requirements of the national product standard. Follow all minimum clearances shown in this manual.

NOTICE: If your installation does not meet the minimum clearances shown, you must do one of the following:

raise the mantel to an acceptable height

remove the mantel

INSTALLING GAS PIPING TO FIREPLACE LOCATION

WARNING: A qualified service person must con- nect fireplace Insert to gas supply. Follow all local codes.

CAUTION: Never connect propane/LP heater di- rectly to the propane/LP supply. This heater requires an external regulator (not supplied). Install the external regulator between the heater and propane/LP supply.

WARNING: Never connect natural gas fireplace insert to private (non-utility) gas wells. This gas is commonly known as wellhead gas.

Installation Items Needed

Wall board or facing material (above fireplace) may be of combustible material, including decorative mantel ornaments or other similar projec- tions off of the facing material.

Figure 12 - Minimum Mantel Clearances for Fireplace Insert Installation

*A CSA design-certified equipment shutoff valve with 1/8" NPT tap is an acceptable alternative to test gauge connection. Purchase the optional CSA design-certified equipment shutoff valve from your dealer. See Accessories, page 30.

For propane/LP units, the installer must supply an external regula- tor. The external regulator will reduce incoming gas pressure. You must reduce incoming gas pressure to between 11 and 14 inches of water. If you do not reduce incoming gas pressure, heater regulator damage could occur. Install external regulator with the vent pointing down as shown in Figure 13, page 11. Pointing the vent down protects it from freezing rain or sleet.

CAUTION: Use only new, black iron or steel pipe. Internally-tinned copper tubing may be used in cer- tain areas. Check your local codes. Use pipe of 1/2" diameter or greater to allow proper gas volume to fireplace insert. If pipe is too small, undue loss of volume will occur.
