CHECKING GAS CONNECTIONS
WARNING:
Test all gas piping and connections,
internal and external to unit, for leaks after installing.
or servicing. Correct all leaks at once.
WARNING:
Never use an open flame to check for a
leak. Apply noncorrosive leak detection fluid to all joints.
Bubbles forming show a leak. Correct all leaks at once.
Pressure Testing Gas Supply Piping System
Test Pressures In Excess of 1/2 PSIG (3.5 kPa)
1. Disconnect fireplace and its individual equipment shutoff valve
from the gas supply piping system. Pressures in excess of 1/2 psig
(3.5 kPa) will damage fireplace gas 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 fireplace or opening main
gas valve located on or near gas meter for natural gas fire-
place, or by using compressed air.
4. Check all joints of gas supply piping sytem. Apply noncorro-
sive leak detection fluid to all joints at once.
5. 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 50).
2. Pressurize supply piping system by either opening propane/LP
supply tank valve for propane/LP gas fireplace or opening main
gas valve located on or near gas meter for natural gas fire-
place, or by using compressed air.
4.
Check all joints from propane/LP supply tank or gas meter to
equipment shutoff valve (see Figure 51 for propane/LP or Figure
52 for natural gas). Apply noncorrosive leak detection fluid to all
joints. Bubbles forming show a leak. Correct all leaks at once.

1. Open equipment shutoff valve (see Figure 50).
2. Open propane/LP supply tank valve for propane/LP fireplace
or main gas valve located on or near gas meter for natural
gas fireplace.
3. Check all joints from equipment shutoff valve to gas valve
(see Figure 51 for propane/LP or Figure 52 for natural gas,
Apply noncorrosive leak detection fluid to all joints. Bubbles
formed show a leak. Correct all leaks at once.
5. Light fireplace (see Operating Fireplace, page 25 or 27 depend-
ing on ignition system). Check all other internal joints for leaks.
5. Turn off fireplace (see To Turn Off Gas to Appliance, page 26 or
page 27 depending on ignition system).
