Component Description
3. 2 ″ Hot Water Outlet. Your ENERGY KING
Wood/Coal Boiler is equipped with one hot
water outlet, located at the top of the
appliance, which supplies heated water to
your heating system.
4. Cold Water Inlet (Return). Cold water
inlets return cooled water back to your
Boiler. The ENERGY KING Model A40EK-
D Wood/Coal Boiler is equipped with one 1-
1/2
″ cold water inlet, located on the rear of
the appliance. ENERGY KING Models
35EK-D/45EK-D Wood/Coal Boiler are
equipped with two 1-1/4
″ cold water
inlets, located on the rear of the appliance.
5. Cast Iron Doors. Heavy cast iron fuel
loading and ash removal doors are secured
to the ENERGY KING using door pins (4
included). The door gaskets provide an
airtight seal and should be inspected
regularly to ensure that they are in good
condition at all times. The gasket must be
replaced if it becomes damaged or worn.
Do not operate the ENERGY KING heating
appliance with the fuel loading or ash
removal doors open.
6. Cast Iron Hearth Plates. Cast with the
words “Wood” and “Coal” on opposite
sides, these plates help to ensure the
precise amount of combustion air required
to promote the most efficient combustion
for either fuel. ENERGY KING Wood/Coal
Boilers use two cast iron hearth plates—
one at the front of the burn chamber, and
one at the rear (2 included).
7. Cast Iron Stationary (Wood) Grates. This
is where you build your wood fire. If you
selected the Shaker Grate option, the
Wood Grates will have been replaced with
Shaker Grates at the factory.
Cast Iron Shaker Grates (Optional). (Not
Pictured)This is where you build your wood or
coal fire. The handle to control the Shaker
Grates is located at the front of the ENERGY
KING, on the left side of the ash removal
door.
8. Firebrick. (9 ″ x 4-1/2 ″ x 1-1/4 ″ ) 2000-
degree, heat retentive firebricks protect the
sides of the Boiler’s burn chamber.
ENERGY KING A40EK-D Boilers and
35EK-D Boilers use 12 firebricks (6 on
each side). The ENERGY KING 45EK-D
Boiler uses 14 firebricks (7 on each side).
9. Ash Removal Pan. Designed for easy
cleanup of fine ash accumulation. Do not
operate the ENERGY KING heating
appliance with the ash removal door open;
keep it closed except to remove ashes. The
ash removal door gasket provides an
airtight seal and should be inspected to
ensure that it is in good condition at all
times. The gasket must be replaced if it
becomes damaged or worn.
Control Box. (Not Pictured) Controls the
Boiler’s electrical system. The control box is
pre-wired for forced air draft.
Combustion Blower. (Not Pictured) This
blower will supply air for combustion by
forcing air into the burn chamber when your
wall thermostat calls for heat.
24-V Wall Thermostat. (Not Pictured) Tells
your ENERGY KING heating appliance when
your home has cooled below your preferred
temperature. Your draft system is controlled
primarily by your wall thermostat.
Aquastat-Immersion Control. (Not Pictured)
Provides boiler water regulation by controlling
the high and low water-temperature limits.
See
Appendix D
for further information.
Pressure-Temperature Gauge. (Not
Pictured) Shows the water pressure and
water temperature within your ENERGY KING
Wood/Coal Boiler.
Pressure Relief Valve. (Not Pictured) A
safety feature, the pressure relief valve will
release excess pressure within your ENERGY
KING Wood/Coal Boiler.
See
Plumbing
for
further instructions.
10. Insulated Cabinet . The colored steel
cabinet panels (sides and top) restrain the
foil-backed insulation, allowing maximum
heat from the Boiler to be circulated
through the home’s hydronic heating
system.
11. Legs . Raise the ENERGY KING heating
appliance off the floor to prevent the
accumulation of moisture between the floor
and the bottom of the appliance.
Domestic Hot Water Coil, 4 ″ (Optional):
(Not Pictured) For heating domestic hot water.
The domestic hot water coil is not available
on ENERGY KING A40EK-D Boilers.
