CHECKING GAS CONNECTIONS
WARNING
: Test all gas piping and connections for leaks after installing or servicing. Correct all leaks immediately.
WARNING
: Never use an open flame to check for a leak. Apply a mixture of liquid soap and water to all joints. If bubbles
form, there may be a leak. Correct all leaks immediately.
Pressure Testing Gas Supply Piping System
Test Pressures In Excess Of 1/2 PSIG ( 3.5kPa )
1. Disconnect heater with its appliance main gas valve (control valve) and equipment 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 equipment shutoff valve was connected.
3. Pressurize supply piping system by either using compressed air or opening gas supply tank valve.
4. Check all joints of gas supply piping system. Apply mixture of liquid soap and water to gas joints. If bubbles form, there may
be a leak.
5. Correct all leaks immediately.
6. Reconnect heater and equipment shutoff valve to gas supply. Check reconnected fittings for leaks.
Test Pressures Equal To or Less Than 1/2 PSIG (3.5 kPa)
1. Close equipment shutoff valve (see Fig. 12).
2. Pressure supply piping system by either using compressed air or opening gas supply tank valve.
3. Check all joints from gas meter to equipment shutoff valve (see Fig. 13). Apply mixture of liquid soap and water to gas joints.
If bubbles form, there may be a leak.
4. Correct all leaks immediately.
Pressure Testing Heater Gas Connections
1. Open equipment shutoff valve (see Fig. 12).
2. Open gas supply tank valve.
3. Make sure control knob of heater is in the OFF position.
4. Check all joints from equipment shutoff valve to control valve (Fig. 13). Apply mixture of liquid soap and water to gas joints.
If bubbles form, there may be a leak.
5. Light heater (see Operation, page 19). Check all other internal joints for leaks.
6. Turn off heater (see To "Turn Off Gas to Appliance," page 20).

2. Remove 5 screws as shown in Figure 15, unplug two wires from the valve, and then remove the manifold.
3. Replace LP gas orifices; see Figure 16
4. Follow the conversion kit instruction inside the package to replace the conversion kit;
5. Place the manifold back into the heater, and connect two wires back into the valve.
6. Install Access Door back to the heater.
7. Remove the conversion kit sticker from the package. Then place sticker over the natural gas certification label.
