CHECKING GAS CONNECTIONS
WARNING: Test all gas piping and connections 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.
PRESSURE TESTING GAS SUPPLY PIPING SYSTEM
Test Pressures In Excess Of 1/2 PSIG (3.5 kPa)
1. Disconnect log set and its individual equipment shutoff valve from
gas supply piping system.
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 log set and equipment shutoff valve to gas supply.
Check reconnected fittings for leaks.

Shutoff Valve
Test Pressures Equal To or Less Than 1/2 PSIG (3.5 kPa)
1. Close equipment shutoff valve (see Figure 4).
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 for natural gas (Figure 5) or
propane/LP supply (Figure 6) to equipment shutoff valve. Apply
noncorrosive leak detection fluid to all joints. Bubbles forming
show a leak.
4. Correct all leaks at once.
