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. 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.
The gas control valve is secured to the burner pan

assembly underneath the front ledge. A 1/8" NPT

plugged tapping is provided on the gas control

valve for a test gauge connection immediately

upstream of the gas supply connection to the ap-

pliance (see Figures 13 and 14).

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 ap-

pliance’s 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.
