Continued
Test Pressures Equal To or Less Than
1/2 PSIG (3.5 kPa)
1. Close equipment shutoff valve (see Figure 15).
2. Pressurize supply piping system by either
opening propane/LP supply tank valve for
propane/LP gas or opening main gas valve lo-
cated on or near gas meter for natural gas, or
using compressed air.
3. Check all joints from propane/LP supply tank
to equipment shutoff valve for propane/LP gas
(see Figure 16) or from gas meter to equip-
ment shutoff valve for natural gas (see Figure
17). Apply noncorrosive leak detection fluid
to gas joints. Bubbles forming show a leak.
4. Correct all leaks at once.
PRESSURE TESTING HEATER GAS
CONNECTIONS
1. Open equipment shutoff valve (see Figure 15).
2. Open propane/LP supply tank valve or main
gas valve located on or near gas meter for
natural gas.
3. Make sure control knob of heater is in the OFF
position.
4. Check all joints from propane/LP supply tank
to equipment shutoff valve for propane/LP gas
(see Figure 16) or from gas meter to equip-
ment shutoff valve for natural gas (see Figure
17). Apply noncorrosive leak detection fluid
to gas joints. Bubbles forming show a leak.
5. Correct all leaks at once.
6. Light heater (see Operating Heater, page 19).
