Test pressures equal or less than 1/2 PSIG
(3,5 Kpa)
1. Close equipment shutoff valve (see figure 8).
2. Pressurize supply piping system by either
opening propane/LP supply tank valve
located on or near gas meter for natural
gas, or using compressed air.
3. Check all joints from gas meter for natural
gas (see figure B) or propane/LP supply
tank for propane /LP gas, to equipment
shutoff valve (see figure C). Apply a non-
corrosive leak detection fluid to all joints.
Bubbles forming show a leak.
4. Correct all leaks at once.
PRESSURE TESTING HEATER GAS CONNEC-
TIONS
1. Open equipment shutoff valve (see figure
A).
2. For natural gas open main gas valve locat-
ed on or near gas meter. For propane/LP
gas open propane /LP supply tank valve.
3. Make sure control knob of heater is in the
OFF position.
4. Check all joints from equipment shutoff
valve thermostat gas valve (see figure
8/9 or 10). Apply a non-corrosive leak
detection fluid to all joints. Bubbles form-
ing show a leak.
5. Correct all leaks at once.
6. Light heater (see operating heater, page
11). Check all other internal joints for
leaks.
7. Turn off heater (see to turn off gas to appli-
