Test Pressures Equal To or Less Than
1/2 PSIG (3.5 kPa)
1. Close equipment shutoff valve (see Fig-
ure 17).
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 equip-
ment shutoff valve for natural gas or
propane/LP supply to equipment shutoff
valve for propane/LP (see Figure 18 or 19).
Apply noncorrosive leak detection fluid to
all joints. Bubbles forming show a leak.
4. Correct all leaks at once.

1. Open equipment shutoff valve (see Fig-
ure 17).
2. Open main gas valve located on or near
gas meter for natural gas or open pro-
pane/LP supply tank valve.
3. Make sure control knob of heater is in the
OFF position.
4. Check all joints from equipment shutoff
valve to thermostat gas valve (Thermo-
stat-Controlled Models) or to gas control
(Remote-Ready Models) (see Figure 18 or
19). Apply noncorrosive leak detection fluid
to all joints. Bubbles forming show a leak.
5. Correct all leaks at once.
6. Light heater (see
Operation
, page 19 or
