Pressure Testing Heater Gas Connections:

1.Make sure that the heater supply piping sys- tem is connected and has been leak tested as described above.

2.Make sure control knob of heater is in OFF position.

3.Open equipment shutoff valve (see figure 13).

4.Open main gas valve on or near gas meter.

5.Check all joints from equipment shutoff valve to control valve (see figure 14). Apply mixture of liquid soap and water to gas joints. Bubbles forming show a leak.

6.Correct all leaks at once.

7.Light heater (see Operating Your Heater, pages 11 and 12 for thermostat models or pages 9 and 10 for non-thermostat models). Check the rest of the internal joints for leaks.

8.Turn off heater (see To Turn OFF Gas to Appli- ance, page 12 for thermostat models and page 11 for non-thermostat models).

9.Replace lower front panel.
