PRESSURE TESTING GAS SUPPLY PIPING SYSTEM

1. Disconnect replace and its individual equipment shutoff valve
from gas supply piping system. Pressures in excess of 1/2 psig
(3.5 kPa) will damage replace 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 replace or opening main
gas valve located on or near gas meter for natural gas replace,
or using compressed air.
4. Check all joints of gas supply piping system. Apply noncor-
rosive leak detection uid to all joints. Bubbles forming show
a leak. Correct all leaks at once.
5. Reconnect replace and equipment shutoff valve to gas supply.
Check reconnected ttings for leaks.

1. Close equipment shutoff valve (see Figure 33).
2. Pressurize supply piping system by either opening propane/LP
supply tank valve for propane/LP gas replace or opening main
gas valve located on or near gas meter for natural gas replace,
or using compressed air.
3. Check all joints from propane/LP supply tank or gas meter
to equipment shutoff valve (see Figure 34 for propane/LP or
Figure 35 for natural gas). Apply noncorrosive leak detection
uid to all joints. Bubbles forming show a leak. Correct all
leaks at once.

1. Open equipment shutoff valve (see Figure 33).
2. Open propane/LP supply tank valve for propane/LP replace
or main gas valve located on or near gas meter for natural gas
replace.
3. Make sure control knob of replace is in the OFF position.
4. Check all joints from equipment shutoff valve to gas valve (see
Figure 34 or 35). Apply noncorrosive leak detection uid to all
joints. Bubbles forming show a leak. Correct all leaks at once.
5. Light replace (see Operating Fireplace, page 23). Check all
other internal joints for leaks.
6. Turn off replace (see To Turn Off Gas to Appliance, page 23).
