Installation

Continued

This unit has been tested for installation at high altitude in accordance with Canadian test stan- dard CAN/CGA-2.17. Higher altitudes affect the atmospheric pressure and heat valve of gaseous fuels. When installing this unit at high altitudes, the rated input will be lower than at sea level. The lowered oxygen content in the air and the lowered gas density require installation of a different size orifice in order to achieve clean combustion of the unit. Consult the unit data plate for the proper high-altitude orifice size. Fill out the information sticker attached to the unit when field converting. See Specifications, page 14, when derating.

GAS LINE HOOK-UP

WARNING: Gas line hookup should be done by your gas supplier or a qualified service person.

WARNING: Before you pro- ceed, make sure your gas supply is OFF.

A manual shutoff valve has been included in the appliance’s gas supply system. You may consider installing an extra gas shutoff valve outside the appliance’s enclosure (check with local codes) where it can be accessed more conveniently with a key through a wall as shown in Figure 14.

Route a 1/2" NPT gas line towards appliance coming in from back of appliance. If installation permits, you may alternately route your incoming gas line from bottom of appliance toward either end. It is recommended to route gas pipe from back of fireplace if possible.

CAUTION: Do not kink flex- ible gas line.

CAUTION: Compounds used on threaded joints of gas piping shall be resistant to the action of Liquefied Petroleum (propane/ LP) and should be applied lightly to ensure excess sealant does not enter the gas line.

1.Install a sediment trap between incoming gas line and gas control valve (see Figure 15). Sediment trap should extend down center of pipe. Refer to your local codes.
