1. Thread the gas control valve onto the burner inlet fitting (see
Figure 7). Use thread sealant on the male threads of the burner
inlet fitting. Hold the burner inlet fitting with a wrench to prevent
overtightening the connection to the burner. Make sure the control
rod is facing the front (see Figure 7).
2. Attach the pilot gas line to the pilot outlet of the gas control valve
and tighten. Connect the thermocouple to the rear of the gas
control valve. See Figure 8. Do not overtighten. If using propane/
LP gas, see
Changing Pilot Orifice
, page 6.
3. Install the inlet fitting into the inlet opening of the gas control valve
(see Figure 9). Use thread sealant on the male pipe threads.
