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.
Pressure Testing Gas Supply Piping System
Test Pressures In Excess Of 1/2 PSIG (3.5 kPa)
1.Disconnect appliance with its appliance main gas valve (control valve) and equip- ment shutoff valve from gas supply pip- ing system. Pressures in excess 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 main gas valve located on or near gas meter.
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.
Test Pressures Equal To or Less Than 1/2 PSIG (3.5 kPa)
1.Close equipment shutoff valve (see Fig- ure 14).
2.Pressurize supply piping system by ei- ther using compressed air or opening main gas valve located on or near gas meter.
3.Check all joints from gas meter to equipment shutoff valve (see Figure 15). 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 14).
2.Open main gas valve located on or near gas meter.
3.Make sure control knob of heater is in the OFF position.
4.Check all joints from equipment shutoff valve to control valve (see Figure 15). Apply mixture of liquid soap and wa- ter to gas joints. Bubbles forming show a leak.
5.Correct all leaks at once.
6.Light heater (see Operating Heater, pages 12 and 13). Check the rest of the internal joints for leaks.
7.Turn off heater (see To Turn Off Gas to Appliance, page 13).
8.Replace front panel.
