4.Appliance shuts off during use. (Pilot stays on.)

a.Low line pressure - Check line pressure to the valve.

b.Defective thermopile - Check pilot flame, check wire con- nections, output should be a minimum of 325 millivolts across. TH/TP and TP terminals with ON/OFF switch off.

5.Gas odor even when control knob is in OFF position.

c.Inlet gas pressure is too low - Contact qualified service person.

9.If burning at main burner orifice occurs (a loud, roaring blow torch noise).

a.You must turn off burner assembly and contact a qualified service person.

b.Manifold pressure is too low - Contact local gas com- pany.

c.Burner orifice clogged - Clean burner or replace burner orifice.

10.Logs appear to smoke after initial operation.
