PART 2. ELECTRICAL
A. ELECTRICAL CONNECTION
The electrical connection for the Munchkin is on the left hand side of the unit. There is a ½" knockout
location for an electrical connection for both the incoming power and the central heating circulator
connection. All electrical wiring must be performed by a qualified licensed electrician in accordance
with National Electrical Code ANSI/NEPA to and/or the Canadian Electrical Code, Part 1 CSA C22.1, or
to the applicable codes and standards. For your convenience, we have labeled all the wires that need
to be connected to operate the Munchkin.
Electrical wiring on the Incoming Power and Central Heating Circulator shall be
connected directly to the intended connection source and not be connected together
inside the electric box provided. An Electrical Short will result and the Control board
will have to be replaced! If Electrical Requirements of the Central Heating Circulator
exceeds 4 amps (or 3 amps on HA models only) please follow the wiring diagrams on
Page 9, Figures 2-1, 2-2 and 2-3.
The electrical requirements are for standard 120 volts, 60 Hz 15 Amp service. This unit is wired with
#18 awg and fused for no more than 15 Amps.
IT IS EXTREMELY IMPORTANT THAT THIS UNIT BE PROPERLY GROUNDED!
IT IS VERY IMPORTANT THAT THE BUILDING GROUND IS INSPECTED BY A
QUALIFIED ELECTRICIAN PRIOR TO MAKING THIS CONNECTION!
There are two ground points in the electrical compartment that must be connected to the building
ground system. Connect the building ground to the green ground screw and the green ground wire
inside electrical box provided.
The Incoming Power Supply is connected to the Black (Hot) and the White (Neutral).The Munchkin
Control board is polarity sensitive. If the polarity is reversed, the Munchkin control will not sense a
flame and lock out the system. The Orange and Brown wire are provided to the supply of 120 volts to
the Central Heating Circulator. Connect the Orange (Hot) and the Brown (Neutral) directly to the Central
Heating Circulator.
The Orange wire for the Central Heating Circulator is Switched Hot and must have a
wire nut if not connected to the Central Heating Circulator. Failure to follow this
instruction will result in a short, and the Control Board will have to be replaced.
Connect the gray wires to your heating thermostat (TT) connection. Your thermostat heat anticipator
setting is .056 amp.
