GAS SUPPLY TESTING

Note: This section is intended as a guide for quali- fied technicians installing gas to this appliance.

CAUTION: Do not connect appliance before pressure test- ing gas piping. Damage to gas valve may result and an unsafe condition may be caused.

The appliance and its individual shut-off valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of 1/2 psig (3.5 kPa).

The appliance must be isolated from the gas sup- ply piping system by closing its individual manual shut-off valve during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 psig (3.5 kPa).

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 15, 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
applianceʼs gas supply system. You may consider
installing an extra gas shutoff valve outside the ap-
plianceʼs enclosure (check with local codes) where
it can be accessed more conveniently with a key
through a wall as shown in Figure 15, page 10.
A 30" long, 1/2" NPT SCHD 40 flexible gas line
(supplied) may be used between the incoming 1/2"
NPT black iron gas line and the fireplace regulator
(located inside the firebox, under the access plate).
The incoming gas line may be routed toward the
appliance from either the left or right hand side of
fireplace outer surround.
