OPEN­THE­GAS­SUPPLY­VALVE­OR­VALVES.­
Set­the­thermostat­to­the­OFF­position.­See­
Figure­5.­If­the­manual­gas­control­knob­
on­the­gas­valve­is­not­in­the­OFF­position,­
partially depress the knob and rotate to the
OFF­position.­See­Figure­6.
Wait­5­minutes­to­allow­gas­that­may­have­
accumulated in the main burner to escape
(especially­important­after­installation).
Turn­the­manual­gas­control­knob­to­the­PILOT­position.
