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.
Cold Water Inlet (Return). (Not pictured)
Cold water inlets return cooled water back to
your Boiler. The ENERGY KING Model
A40EKB Wood/Coal Boiler is equipped with
one 1-1/2
″ cold water inlet, located on the rear
of the appliance. ENERGY KING Models
35EKB/45EKB Wood/Coal Boiler are
equipped with two 1-1/4
″ cold water inlets,
located on the rear of the appliance.
4. 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.
5. 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).
Cast Iron Stationary (Wood) Grates. (Not
pictured) 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.
6. Cast Iron Shaker Grates (Optional).
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.
7. 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 A40EKB Boilers and
35EKB Boilers use 12 firebricks (6 on
each side). The ENERGY KING 45EKB
Boiler uses 14 firebricks (7 on each side).
Ash Removal Pan. (Not Pictured) 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.
8. Control Box. Controls the Boiler’s
electrical system. The control box is pre-
wired for forced air draft.
9. Combustion Blower. 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.
10. Aquastat-Immersion Control. Provides
boiler water regulation by controlling the
high and low water-temperature limits.
See
Appendix D
for further information.
11. Pressure-Temperature Gauge. Shows
the water pressure and water temperature
within your ENERGY KING Wood/Coal
Boiler.
12. Pressure Relief Valve. A safety feature,
the pressure relief valve will release
excess pressure within your ENERGY
KING Wood/Coal Boiler.
See
Plumbing
for
further instructions.
13. 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.
14. 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 A40EKB Boilers.
