What should I use to test for gas leaks?

You should apply a mixture of liquid soap and water to all joints and look for bubbles forming, which indicate a leak.

Is it safe to use an open flame to check for a gas leak?

No, it's never safe to use an open flame. Always use the liquid soap and water method to test for leaks.

Where should the external regulator be installed for a propane/LP supply?

The external regulator should be installed between the propane/LP supply and the heater. Refer to guidelines under 'Connecting to Gas Supply, page 12' for detailed instructions.

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- necting to Gas Supply, page 12.

Pressure Testing Gas Supply Piping System

Test Pressures In Excess Of 1/2 PSIG

Test Pressures Equal To or Less Than 1/2 PSIG

1.Close manual shutoff valve (see Fig- ure 15).

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 manual shutoff valve (see Figure 16). 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 manual shutoff valve (see Fig- ure 15).

2.Open propane/LP supply tank valve.

3.Make sure control knob of heater is in the OFF position.

4.Check all joints from manual shutoff valve to thermostat gas valve (thermo- stat-controlled models) or control valve (variably-controlled models) (see Fig- ure 16). 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 15 and 16 [Thermostat- Controlled Models] or pages 16 and 17 [Variable Manually- Controlled Models]). Check all other internal joints for leaks.

7.Turn off heater (see To Turn Off Gas to Appliance, page 16 [Thermostat-Con- trolled Models] or page 17

[Variable Manually-Controlled Models]).

1.	Disconnect heater and its individual
	manual shutoff valve from gas supply
	piping system. Pressures in excess of
	1/2 psig will damage heater regulator.
2.	Cap off open end of gas pipe where
	manual 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 manual shutoff
	valve to gas supply. Check re-
