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 a noncorrosive leak detection fluid to
all joints. Bubbles forming show a leak. Correct all
leaks at once.
CAUTION: Make sure external regulator has been
installed between propane/LP supply and fireplace.
See guidelines under Connecting Fireplace to Gas
Supply.
PRESSURE TESTING GAS SUPPLY PIPING SYSTEM
Test Pressures In Excess Of 1/2 PSIG (3.5 kPa)
1. Disconnect fireplace 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 fireplace 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 11).
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 supply to equipment shutoff valve for propane/
LP (see Figures 12 or 13). 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 11).
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 control valve
(see Figures 12 or 13). Apply noncorrosive leak detection fluid to
all joints. Bubbles forming show a leak.
5. Correct all leaks at once.
6. Light fireplace (see Operation, page 14). Check all other internal
joints for leaks.
7. Turn off fireplace (see To Turn Off Gas to Appliance, page 14).
