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: Surface temperatures of adjacent walls and mantels be- come hot during operation. Walls and mantels above the firebox may become hot to the touch. If installed properly, these tempera- tures meet the requirement of the national product standard. Fol- low 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 accept- able height

remove the mantel

WARNING: A qualified ser- vice person must connect fire- place to gas supply. Follow all local codes.

CAUTION: Never connect heater directly to the propane/LP supply. This heater requires an ex- ternal regulator (not supplied). In- stall the external regulator between the heater and propane/LP supply.

Installation Items Needed

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

external regulator (supplied by installer)

piping (check local codes)

sealant (resistant to propane/LP gas)

equipment shutoff valve *

test gauge connection *

sediment trap

tee joint

pipe wrench

approved flexible gas line with gas connec- tor (if allowed by local codes) (not provided)

chase the optional CSA design-certified

equipment shutoff valve from your dealer.

See Accessories, pages 24 and 25.

The installer must supply an external regu- lator. 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 incom- ing gas pressure, heater regulator damage could occur. Install external regulator with the vent pointing down as shown in Figure

16.Pointing the vent down protects it from freezing rain or sleet.

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

Installation must include an equipment shutoff valve, union, and plugged 1/8" NPT

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