C. LIGHTING INSTRUCTIONS
FOR YOUR OWN SAFETY READ BEFORE OPERATING
1. This appliance does not have pilot. It is equipped with an ignition device which automatical-
ly lights the burner. Do not try to light the burner by hand.
2. BEFORE OPERATING smell all around the appliance area for gas. Be sure to smell next to the
floor because some gas is heavier than air and will settle on the floor.
WHAT TO DO IF YOU SMELL GAS
• Do not try to light any appliance.
• Do not touch any electric switch; do not use any phone in your building.
• Immediately call your gas supplier from a neighbor's phone. Follow the gas suppliers'
instructions.
• If you cannot reach your gas supplier, call the fire department.
3. Turn on gas shutoff valve (located inside of the Heater) so that the handle is aligned with the
gas pipe. If the handle will not turn by hand, don't try to repair it, call a qualified service tech-
nician. Force or attempted repair may result in a fire or explosion.
4. Do not use this appliance if any part has been under water. Immediately call a qualified serv-
ice technician to inspect the appliance and to replace any part of the control system and any
gas control which has been under water.
5. The Munchkin Boiler shall be installed so the gas ignition system components are protected
from water (dripping, spraying, rain, etc.) during appliance operation and service (circulator
replacement, condensate trap, control replacement, etc.)
