Mantel Clearances for Built-In Installation

If placing mantel above built-in fireplace, you must meet minimum clearance between mantel shelf and top of fireplace opening.

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

raise the mantel to an acceptable height

remove the mantel

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 requirement of the national product standard. Follow all minimum clearances shown in this manual.

INSTALLING GAS PIPING TO FIREPLACE LOCATION

WARNING: This appliance requires a 1/2" NPT (National Pipe Thread) inlet connection to the pres- sure regulator.

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

CAUTION: Never connect propane/LP fireplace directly to the propane/LP supply. This fireplace requires an external regulator (not supplied). Install the external regulator between the fireplace and pro- pane/LP supply.

Wall board or facing material (above firebox) may be of

Installation Items Needed

Before installing fireplace, make sure you have the items listed below.

external regulator for propane/LP unit only (supplied by installer)

piping (check local codes)

sealant (resistant to propane/LP gas)

equipment shutoff valve *

test gauge connection *

sediment trap (optional)

tee joint

pipe wrench

approved flexible gas line with gas connector (if allowed by lo- cal codes) (not provided)

*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, pages 34 and 35.

Figure 20 - Minimum Mantel Clearances for Built-In Installation

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 point- ing down as shown in Figure 21, page 13. Pointing the vent down protects it from freezing rain or sleet.
