2. Cap off open end of gas pipe where equip-
ment shutoff valve was connected.
3. Pressurize supply piping system by either
opening propane/LP supply tank valve for
propane/LP gas burner system or opening
main gas valve located on or near gas
meter for natural gas burner system, or
using compressed air.
4. Check all joints of gas supply piping sys
-
tem. Apply noncorrosive leak test solution
to all gas joints. Bubbles forming show a
leak. Correct all leaks at once.
5. Reconnect burner system and equipment
shutoff valve to gas supply. Check recon-
nected fittings for leaks.
Test Pressures Equal To or Less Than
1/2 PSIG (3.5 kPa)
1. Close equipment shutoff valve (see Fig-
ure 31).
2. Pressurize supply piping system by either
opening propane/LP supply tank valve for
propane/LP gas burner system or opening
main gas valve located on or near gas
meter for natural gas burner system, or
using compressed air.
3. Check all joints from propane/LP supply
tank or gas meter to equipment shutoff
valve (see Figure 32 for propane/LP or
Figure 33 for natural gas). Apply noncor-
rosive leak test solution to all gas joints.
Bubbles forming show a leak. Correct all
leaks at once.
PRESSURE TESTING BURNER SySTEM
GAS CONNECTIONS
1. Open equipment shutoff valve (see Fig-
ure 31).
2. Open propane/LP supply tank valve for
propane/LP burner system or main gas
valve located on or near gas meter for
natural gas burner system.
3. Make sure control knob of burner system
is in the OFF position.
4. Check all joints from equipment shutoff
valve to thermostat gas valve (see Figure
32 for propane/LP or Figure 33 for natu-
ral). Apply commercial leak test solution
to all gas joints. Bubbles forming show a
leak. Correct all leaks at once.
