page 16.
PRESSURE TESTING GAS SUPPLY PIPING
SYSTEM
Test Pressures In Excess Of 1/2 PSIG (3.5 kPa)
1. Disconnect appliance with its appliance main
gas valve (control valve) and equipment
shutoff valve from gas supply piping system.
Pressures in excess of 1/2 psig will damage
heater regulator.
2. Cap off open end of gas pipe where equipment
shutoff valve was connected.
3. Pressurize supply piping system by either
opening propane/LP supply tank valve for
propane/LP gas or opening main gas valve
located on or near gas meter for natural gas,
or using compressed air.
4. Check all joints of gas supply piping system.
Apply noncorrosive leak detection fluid to all
joints. Bubbles forming show a leak.
5. Correct all leaks at once.
6. Reconnect fireplace and equipment shutoff
valve to gas supply. Check reconnected fittings
for leaks.
Test Pressures Equal To or Less Than 1/2 PSIG
(3.5 kPa)
1.
Close equipment shutoff valve (see Figure 24).
2. Pressurize supply piping system by either
opening propane/LP supply tank valve for
propane/LP gas or opening main gas valve
located on or near gas meter for natural gas,
or using compressed air.
3. Check all joints from gas meter to equipment
shutoff valve for natural gas or propane/LP sup
-
ply to equipment shutoff valve for propane/LP
(see Figures 25 or 26). Apply noncorrosive leak
detection fluid to all joints. Bubbles forming
show a leak.
4. Correct all leaks at once.
PRESSURE TESTING FIREPLACE GAS
CONNECTIONS
1.
Open equipment shutoff valve (see Figure 24).
2. Open main gas valve located on or near gas
meter for natural gas or open propane/LP
supply tank valve.
3. Make sure control knob of fireplace is in the
OFF position.
4. Check all joints from equipment shutoff
valve to gas regulator (Thermostat-Controlled
Models), or to gas control valve (Remote-
Ready Models) (see Figures 25 or 26). Apply
noncorrosive leak detection fluid to all joints.
Bubbles forming show a leak.
5. Correct all leaks at once.
6. Light fireplace (see Operating Fireplace, page
22). Check all other internal joints for leaks.
7.
Turn off fireplace (see To Turn Off Gas to Appli-
ance, page 23 for Thermostat-Controlled Mod
-
els or page 25 for Remote-Ready Models).
