WARNING: Risk of Explosion or Fire.
Verify that there are no gas leaks by testing with
appropriate equipment. Never use a match or lighter
to test for the presence of gas. Failure to test
properly can lead to an explosion or fire and may
result in severe personal injury or death.
Make sure all components are functioning properly by
performing the following test:
1. Test all joints and connections for leaks with a
soap solution.
2. Set the thermostat to the lowest setting.

3. Close the main manual shutoff valve (A valve) and
the pilot valve (B valve [see Figure 1]) and wait at
least 5 minutes for unburned gas to escape from
the appliance.
4. Reopen the B valve, push down the red lever and
light the pilot burner. Continue to hold down the
red lever for approximately 30 seconds.
5. Open the A valve. The main burner ignites from
the pilot burner when the thermostat calls for heat.
6. Disconnect the thermocouple from the L62GB.
The main valve should close immediately. If it
does not close, check for wiring errors. Reconnect
the thermocouple to the L62GB when it is
operating correctly.
