B. ITEMS TO BE CHECKED BEFORE LIGHTING THE MUNCHKIN
It is recommended that you read the General Information Section (Part 1) to get a better under-
standing how the Munchkin operates before you start the unit.
1. Make sure that you follow the Lighting instruction before running the Munchkin.
2. Check to see if all the electrical connections are on securely.
3. Make sure that the Gas is turned on inside the cabinet and outside of the Munchkin.
4. Double check the temperature setting (Note: The Munchkin is factory set at 119 degrees)
5. Make sure the unit is properly grounded and the electrical wiring meets the requirements of
the electrical section (Part 2).
6. Turn on the power to the Munchkin. The Temperature of the Munchkin Outlet will appear in
the display provided. If a fault code appears, correct the fault before operating. Make sure that
the flow switch is connected and adjust the setpoint for the desired water temperature. The
Munchkin will now run its pre-purge cycle, then begin running, which will be indicated by the
Green light illuminating under "Flame On" in your display.
If you do not follow these instructions exactly, a fire or explosion may
result, causing property damage, personal injury or loss of life.
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.

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 Heater 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.)
