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
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- ance, page 12)
