CHECKING GAS
CONNECTIONS
WARNING: Test all gas pip- ing and connections for leaks after installing or servicing. Cor- rect all leaks at once.
WARNING: Never use an open flame to check for a leak. Apply a mixture of liquid soap and water to all joints. Bubbles forming show a leak. Correct all leaks at once.
CAUTION: Make sure exter- nal regulator has been installed between propane/LP supply and heater. See guidelines under Con-
Test Pressures Equal To or Less Than 1/2 PSIG (3.5 kPa)
1.Close equipment shutoff valve (see Fig- ure 22).
2.Pressurize supply piping system by ei- ther using compressed air or opening propane/LP supply tank valve.
3.Check all joints from propane/LP sup- ply tank to equipment shutoff valve (see Figure 23). Apply mixture of liquid soap and water 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 Fig- ure 22).
2.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 to thermostat gas valve (see Fig- ure 23). Apply mixture of liquid soap and water to gas joints. Bubbles form- ing show a leak.
5.Correct all leaks at once.
6.Light heater (see Operating Heater, pages 14 and 15). Check all other in- ternal joints for leaks.
7.Turn off heater (see To Turn Off Gas to Appliance, page 14).
8.Replace front panel.

Pressure Testing Gas Supply Piping System
Test Pressures In Excess Of 1/2 PSIG (3.5 kPa)
1.Disconnect appliance with its appli- ance main gas valve (control valve) and equipment shutoff valve from gas supply piping system. Pressures in ex- cess of 1/2 psig will damage heater regulator.
2.Cap off open end of gas pipe where equipment shutoff valve was connected.
3.Pressurize supply piping system by ei- ther using compressed air or opening propane/LP supply tank valve.
4.Check all joints of gas supply piping system. Apply mixture of liquid soap and water to gas joints. Bubbles form- ing show a leak.
5.Correct all leaks at once.
6.Reconnect heater and equipment shutoff valve to gas supply. Check re- connected fittings for leaks.
