Important Notes for Gas Connection:
• The appliance and its individual gas shutoff valve must be disconnected from
the gas supply piping system during any pressure testing of that system at
test pressures in excess of 1/2 psig (3.5kPa).
• The appliance must be isolated from the gas supply piping system by closing
its individual manual shut-off valve during any pressure testing of the gas sup-
ply piping system at test pressures equal to or less than 1/2 psi (3.5kPa).
Before connecting 5-foot (1.5 m) supply cord to wall receptacle, make certain that
gas shutoff valve and all burner controls are in OFF position.
After electrical connection is complete, place each burner cap in correct sized
notched position and check operation of electric igniters. Check flame characteris-
tics. Flame should be blue with no yellow tip.
Yellow Flames:
Further adjustment is required.
Yellow Tips on Outer Cones:
Normal for LP Gas.
Soft Blue Flames:
Normal for Natural Gas.
If the flame is completely or mostly yellow,
verify that the regulator is set for the correct fuel. After adjustment, retest.
Some yellow streaking is normal during the initial start-up. Allow unit to operate
4-5 minutes and re-evaluate before making adjustments.
If the elements do not heat or if the indicator "on" light does not glow, check the
power source to see if a fuse has blown or if the circuit breaker has tripped.
Refer to the Warranty in the Use and Care Manual. See Use and Care manual for
troubleshooting information.
