Component Description

1. 8″ Chimney Outlet. Top Vent. Venting must
be provided using a lined masonry chimney
or a listed UL103 type HT chimney. The
chimney exhausts smoke and flue gases that
are a natural result of combustion and
provides “draft” to the Boiler. Draft is the
force that moves air from the burn chamber

up through the chimney. See Venting for

further instructions.

Figure 1: Components (Cutaway View)

2. Sliding Smoke Baffle. When open, the

sliding smoke baffle allows smoke and flue
gases to flow into the chimney connector
without restriction. When closed, smoke and
flue gases are diverted around the sliding
smoke baffle, creating a longer path for the
heated air and allowing your boiler to extract
the maximum amount of heat from the fire.

Rev 08/24/10 ENERGY KING™ Wood/Coal Boiler Owner’s Manual  U. S. 4

Component Description

3. 2″ Hot Water Outlet. Your ENERGY KING
Wood/Coal Boiler is equipped with one hot

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.

What is ASME-Certification?

ENERGY KING Wood/Coal Boiler model A40EK-D is built and tested to the exacting standards of

the American Society of Mechanical Engineers (ASME) Code Section 4, Construction of Heating
Boilers, under the National Board ‘H’ stamp, and is independently inspected by a third party
inspection agency.

ENERGY KING Wood/Coal Boiler model A40EK-D is constructed of certified, high-grade 1/4”

SA516-70 steel plate and is welded by experienced, ASME-certified welders, to ensure safety and
durability. For additional safety, a 30 PSI pressure relief valve is included with every Energy King
boiler. You can rest easy knowing that ENERGY KING A40EK-D boilers conform to an
internationally recognized standard for safety and quality.

The following information was taken from www.ASME.org and is reproduced here for informational
purposes only. Please visit www.ASME.org for more information about the ASME and codes and
standards.

Founded in 1880 as the American Society of Mechanical Engineers, ASME is a not-for-profit
professional organization that promotes the art, science and practice of mechanical and
multidisciplinary engineering and allied sciences throughout the world. The core values of
ASME are rooted in its mission to better enable mechanical engineering practitioners to
contribute to the well-being of humankind.

What is a standard?

A standard can be defined as a set of technical definitions and guidelines, “how to”
instructions for designers, manufacturers and users. Standards promote safety, reliability,
productivity and efficiency in almost every industry that relies on engineering components or
equipment. Standards can run from a few paragraphs to hundreds of pages, and are written
by experts with knowledge and expertise in a particular field who sit on many committees.

Are standards mandatory?

Standards are considered voluntary because they serve as guidelines, but do not of
themselves have the force of law. ASME cannot force any manufacturer, inspector, or
installer to follow ASME standards. Their use is voluntary.

Standards become mandatory when they have been incorporated into a business contract
or incorporated into regulations.

What is a code?

A code is a standard that has been adopted by one or more governmental bodies and has
the force of law.

Why are standards effective?

Standards are a vehicle of communication for producers and users. They serve as a
common language, defining quality and establishing safety criteria. Costs are lower if
procedures are standardized; training is also simplified.

Interchangeability is another reason. It is not uncommon for a consumer to buy a nut in
California for a bolt purchased in New Jersey.

Fuel Requirements

BURN AIR-DRIED WOOD, OR ANTHRACITE OR BITUMINOUS COAL ONLY

Risk of Fire: Do not store fuel or other combustible
material within the marked installation clearances.

It is important to use fuel that is clean, dry and consistent. Solid-fuel boilers, such as your ENERGY
KING Wood/Coal Boiler, naturally produce ash as a byproduct of the burning process. Even with
the ENERGY KING heating appliance’s highly efficient design, your heating appliance will still
produce some amount of ash which will need to be cleaned periodically. The type and quality of fuel
you burn affects the amount of ash produced and the performance of your heating appliance. To
assist you in determining which fuel to use, here are some guidelines to consider:

Burning wood for heat is as old as civilization itself. More than any other major fuel, wood provides
us with energy independence – an easily available, locally produced and renewable source of heat
on which we can rely.

• The ENERGY KING Wood/Coal Boiler has
been tested for operation with air-dried
wood.

• Wood should be seasoned (dried) for at
least 12 months before burning. Properly
seasoned wood should have about 20% ­25% moisture content. To properly season
wood, split the logs as soon as possible
and loosely stack them in a dry spot for at
least 12 months.

You should not burn wet or green wood in
your Boiler. Burning wet or green wood in
your Boiler will not only reduce the
efficiency of your appliance, but also
increases the risk of dangerous creosote
build-up in your appliance and chimney.

• Softwoods, such as pine and fir, are easily
ignited and burn rapidly with hot flames.
With softwoods, you will spend more time
reloading your ENERGY KING Wood/Coal
Boiler, and will have much more difficulty
achieving an overnight burn. For a longer
lasting fire, it is best to use more dense
hardwoods.

• Ideally, you should burn a mixture of
hardwoods and softwoods, using the hotter,
faster burning softwoods to start your fire,
and the denser hardwoods to maintain a
longer-lasting fire.

WOOD

• With this in mind, choosing the kind of
firewood that is best for you depends on
what is available in your area. If hardwoods
are unavailable in your area, you can
control the burn rate by using larger pieces
of wood.

• DO NOT BURN: Treated wood, colored
paper, garbage, cardboard, solvents, or
trash—burning these may result in toxic
fumes, or produce soot and large flakes of

char or fly ash. Burning treated wood,

colored paper, garbage, cardboard,
solvents or trash can be dangerous and will
void your ENERGY KING warranty.

• DANGER – Risk of Fire or Explosion: Do
not burn garbage, gasoline, naphtha, drain
or engine oil, or other flammable liquids or
inappropriate materials in this heating
appliance.

Storage

• Store all fuel in a dry location away from
the elements. Never burn wet or green
wood.

• Do not store fuel within the heating
appliance installation clearances or within
the space required for refueling, ash
removal and other routine maintenance
operations.

Rev 08/24/10 ENERGY KING™ Wood/Coal Boiler Owner’s Manual  U. S. 8

Fuel Requirements

BURN AIR-DRIED WOOD, OR ANTHRACITE OR BITUMINOUS COAL ONLY

Risk of Fire: Do not store fuel or other combustible
material within the marked installation clearances.

One of the world’s most widely-used fuel sources, coal can provide the energy independence and
low fuel prices sought by owners of solid-fuel heating appliances.

• The ENERGY KING Wood/Coal Boiler has
been tested for operation with anthracite
(hard) or bituminous (soft) coal.

• Anthracite: Also known as Hard Coal,
anthracite is a hard, lustrous coal with a
high carbon content that burns with a clean
blue, nearly smokeless, flame.

• Bituminous: Also known as Soft Coal,
bituminous coal is a soft type of coal that
has a high sulfur content and burns with a
yellow, smoky flame.

• Bituminous coal tends to contain more
impurities and sulfur than anthracite coal,
which may decrease the expected lifespan
of your ENERGY KING solid-fuel heating
appliance and its components. If you
choose to burn bituminous coal, be sure to
select only high-grade bituminous coal.

• Coal Size: Your ENERGY KING
Wood/Coal Boiler is designed to use coal
that is Nut size or larger.

COAL

• DO NOT BURN: Treated wood, colored
paper, garbage, cardboard, solvents, or
trash—burning these may result in toxic
fumes, or produce soot and large flakes

of char or fly ash. Burning treated wood,

colored paper, garbage, cardboard,
solvents or trash can be dangerous and
will void your ENERGY KING warranty.

• DANGER – Risk of Fire or Explosion:
Do not burn garbage, gasoline, naphtha,
drain or engine oil, or other flammable
liquids or inappropriate materials in this
heating appliance.

Storage

• Store all fuel in a dry location away from

the elements. Never burn wet coal.

• Do not store fuel within the heating

appliance installation clearances or
within the space required for refueling,
ash removal and other routine
maintenance operations.

Rev 08/24/10 ENERGY KING™ Wood/Coal Boiler Owner’s Manual  U. S. 9

Installation

Risk of Fire:

• Do not operate with flue draft exceeding .06 in. (14.95 Pa)

water column.

• Do not operate with fuel loading or ash removal doors open.

• Do not store fuel or other combustible material within marked

installation clearances.

• Inspect and clean flues and chimney regularly.

Do not connect the ENERGY KING heating appliance
to any chimney flue serving any other appliance.

General Requirements

The installation of any solid fuel heating appliance is not a do-it-yourself project. The

ENERGY KING Wood/Coal Boiler should be installed by a qualified installer with specific
knowledge of hydronic heating systems. Check with your fire department and building inspector for
local, state, and federal codes and regulations regarding installation.

Solid-fuel heating appliance related fires are caused almost exclusively by installation, operation, or
maintenance errors. A smoke detector in “working” condition must
KING solid-fuel heating appliance installation—this is the most inexpensive insurance you can buy!
For additional safety, RJM Manufacturing, Inc. recommends installing working smoke detectors and
a listed carbon monoxide warning device in the living areas of the home.

The ENERGY KING Wood/Coal Boiler is designed to be used in conjunction with a listed gas- or
oil-fired boiler, or as a central boiler.

Zones
A “heat dump” zone is required for all
installations. The purpose of this zone is to
circulate heated water away from the boiler
when no other zones are calling for heat. In
this way it will prevent your ENERGY KING
Wood/Coal Boiler from overheating. However,
as a safety feature, if your Boiler should
overheat or build up excess pressure, it will
trigger the pressure relief valve which will
release water, thus relieving pressure. See

Plumbing for further instructions.

In-floor Heating
Many newer homes feature in-floor heating.
The ENERGY KING Wood/Coal Boiler may not
be suitable for such applications as it produces
water temperatures in excess of 185-degrees,
which is much greater than can be withstood by

Installation

Assembling Your ENERGY KING Wood/Coal Boiler

The entire installation should be planned before putting the Boiler in place to ensure compliance
with all the requirements outlined in the owner’s manual.

Your new ENERGY KING Wood/Coal Boiler will have been shipped on a pallet with several boxed
components that will need to be assembled prior to installation. Please see “Components” for a list
of everything that was shipped along with your ENERGY KING Wood/Coal Boiler.

Once your Boiler is placed in your desired location:

1. Remove the protective plastic coating from
the outer cabinet of the heating appliance
before assembling.

2. Cast Iron Hearth Plates. Position front and

rear cast iron hearth plates in burn chamber.
Your primary type of fuel (wood or coal) will
determine how to position the hearth plates.
The purpose of proper location is to
introduce the precise amount of combustion
air into the burn chamber to promote the
most efficient combustion for either fuel.

The words “Wood” and “Coal” are cast into
the hearth plates on opposite sides.

a. If you are going to burn wood, position

the hearth plates with the word “Wood”
facing out, not into the burn chamber.

b. If you plan to primarily burn coal,

position the hearth plates with the word
“Coal” facing out.

3. Firebrick. The firebrick in your ENERGY

KING heating appliance will have been
installed at the factory; however they may
have shifted during shipment. If adjustments
are needed, position the firebrick by standing
up on end on the left and right sides of the
burn chamber.

Combustion Air Requirements

The ENERGY KING Wood/Coal Boiler must have a minimum supply

All fuel-burning appliances must have air (oxygen) for proper combustion. The incomplete
combustion that takes place when a solid-fuel appliance is “air-starved” causes carbon monoxide
(CO) production in quantities that can be dangerous inside a building. Combustion air from outside
may need to be brought in to prevent “air starvation”. Although an outside air source is strongly
recommended for all installations, it may be necessary if:

• The heating appliance does not draw steadily, smells, experiences smoke roll­out, burns poorly, or backdrafts, whether or not there is combustion present.

Failure to provide adequate combustion air can
lead to increased carbon monoxide production
and increased emissions of combustion gases
into the building, which may cause death or
serious injury.

of 70 cubic feet of air per minute.

• Any of the above symptoms are alleviated by opening a window slightly on a
calm day.

• The house is equipped with a well-sealed vapor barrier and tight fitting windows
and/or has any powered devices which exhaust house air, such as clothes
dryers.

• A ventilation system is installed in the house.

Consult a qualified boiler installer to analyze whether the air supply in your installation environment
is adequate.

Rev 08/24/10 ENERGY KING™ Wood/Coal Boiler Owner’s Manual  U. S. 15

Installation

Venting System

• Failure to provide correct chimney venting can lead to increased

carbon monoxide production and increased emissions of
combustion gases into the building, which may cause death or
serious injury.

• Do not connect the ENERGY KING heating appliance to any

chimney flue serving any other appliance.

• Risk of Fire: Inspect and clean flues and chimney regularly.

• Risk of Fire: Do not operate with the flue draft exceeding .06″

(14.95 Pa) water column.

Consult a qualified boiler installer, your local building inspector and your fire
officials to make sure the chimney and all connections conform to all local, state and
national codes and regulations.

Your venting system is an extremely important
part of any solid-fuel heating appliance
installation and has two key functions:

1. To exhaust smoke and flue gases which
are the natural result of combustion.

2. To provide “draft.” The draft, along with
your combustion blower, provides a
continuous supply of fresh air for proper
combustion.

A chimney connector and chimney make up the
venting system and must be properly installed
and maintained to protect against a fire.
Consult a chimney and venting specialist.

The ENERGY KING Wood/Coal Boiler requires
installation into a lined masonry chimney or an
8-inch listed UL103 type HT all-fuel factory-built
chimney. Minimum 24 gauge black steel
chimney connector is required. An existing
chimney must be cleaned and inspected to be
sure it is clean and free from defect or damage.
All connections must comply with NFPA
Standard 211 and all applicable building codes
and regulations.

When installing a factory-built chimney, follow
all installation instructions provided by the
chimney manufacturer.

For best performance, RJM Manufacturing, Inc.
recommends using insulated chimney rather
than triple wall or air cooled chimney.

Rev 08/24/10 ENERGY KING™ Wood/Coal Boiler Owner’s Manual  U. S. 16

Important venting installation clearances and
points for proper operation and safety:

• The connection from the ENERGY KING
Wood/Coal Boiler to the chimney must be
made using 8″ black steel material with a
minimum 24 gauge. Do not use galvanized

steel. See Chimney Connector.

• A minimum distance of 18 inches must be
maintained between the chimney connector
and combustible ceiling surfaces.

• A minimum of 18 inches must be maintained
between the chimney connector and the
backwall, and 20 inches between the
connector and sidewalls.

• Secure all connector pipe joints with at least
three sheet metal screws.

• Avoid using more than two elbows in
connecting the heating appliance to the
chimney.

• Any horizontal runs of connector pipe should
have a minimum rise of 1/2-inch per linear
foot. Use extra support hangers or brackets
every three feet if it is absolutely necessary
to have a run of more than six feet, which is
not recommended.

• The chimney must be at least 3 feet higher
than the highest point where it passes
through the roof, and at least 2 feet higher
than the highest part of the roof or structure
that is within 10 feet of the chimney,

measured horizontally. Please refer to Figure
8: Venting Requirements. For best

performance, RJM Manufacturing, Inc.
recommends a chimney height of at least 12
feet.

Installation

The Chimney must be at least 3 feet higher than the highest point where it passes through the roof,
and at least 2 feet higher than the highest part of the roof or structure that is within 10 feet of the
chimney, measured horizontally. For best performance, RJM Manufacturing, Inc. recommends a
chimney height of at least 12 feet.

Figure 8: Venting Requirements

Rev 08/24/10 ENERGY KING™ Wood/Coal Boiler Owner’s Manual  U. S. 17

Installation

Masonry Chimney

When connecting to an existing masonry chimney, an approved liner must be used in the chimney.

An unlined chimney could remain cold and cause a downward pressure which creates the
environment for poor burning, incomplete combustion, or backdraft.

Chimney Connector

The connection from the ENERGY KING Wood/Coal Boiler to the
chimney must be made using 8″ black steel material with a
minimum 24 gauge. Do not use galvanized steel.

For proper operation, the chimney connector should be as short
as possible. Horizontal lengths of chimney connector should
have an upward slope of 1/2-inch per foot. Use extra support
hangers or brackets every three feet if it is absolutely necessary
to have a run of more than six feet, which is not recommended.

Chimney connector sections must be attached to the heating
appliance and to each other with the crimped end toward the
heating appliance. Secure all chimney connector pipe joints with
at least three sheet metal screws. Avoid using more than two
elbows in connecting the ENERGY KING Wood/Coal Boiler to
the chimney.

Never use chimney connector pipe as a chimney.

A minimum distance of 18 inches must be maintained between
the chimney connector and combustible ceiling surfaces.
A minimum of 18 inches must be maintained between the chimney connector and the backwall and
a minimum of 20 inches must be maintained between the chimney connector and sidewalls.

DO NOT PASS CHIMNEY CONNECTOR THROUGH A COMBUSTIBLE WALL OR CEILING.

Installation

Barometric Draft Control

Proper draft must be provided for your
ENERGY KING Wood/Coal Boiler. Draft is the
force that moves air from the boiler up through
the chimney. Draft is measured in inches of
water column.

The amount of draft in your chimney depends
on the length of the chimney, local geography,
nearby obstructions and other factors. Too
much draft may cause the fire to burn too fast,
while inadequate draft may cause smoke to
back up into the ENERGY KING heating
appliance, creating a possible hazard.

A barometric draft control must be installed into

the chimney connector. Please refer to Figure

8: Venting Requirements and Figure 10:
Barometric Draft Control.

Risk of Fire: Do not operate with the flue draft
exceeding .06″ (14.95 Pa) water column.

Moderate draft in
the chimney will
pull the
barometric draft
control open just
enough to
maintain the
appropriate draft
for your heating
appliance.

Figure 10: Barometric Draft Control

Barometric draft controllers limit the draft (the
suction pulling air into the solid-fuel heating
appliance burn chamber). A pivoted,
counterbalanced flap is pulled open by the draft
when the draft reaches a critical amount. This
permits air to enter the chimney, thus
preventing the draft in the heating appliance
from rising any higher.

After installation of the ENERGY KING
Wood/Coal Boiler is complete and a fire has
been built, the chimney draft should be
established and maintained from .04″ to .06″
water column of draft. If this setting is
exceeded, it could cause a solid fuel fire to
burn out of control.

With no draft in the
chimney, the barometric
draft control remains
closed, allowing no air
to enter.

Excessive draft in
the chimney will
pull the
barometric draft
control further
open, allowing
more air into the
chimney and
reducing the draft.

Installation

Plumbing

ENERGY KING A40EK-D Wood/Coal Boilers
are equipped with:

• One 2″ hot water outlet, located at the top
of the Boiler

• One 1-1/2″ cold water inlet, located on the
rear of the Boiler.

ENERGY KING 35EK-D/45EK-D Wood/Coal
Boilers are equipped with:

• One 2″ hot water outlet, located at the top
of the Boiler

• Two 1-1/4″ cold water inlets, located on
the rear of the Boiler.

Important points for proper plumbing:

• Use pipe of no less than 1″ diameter for both
the hot water outlet and the cold water inlets.

• When plumbing into your existing heating
system, RJM Manufacturing, Inc.
recommends installing a series of three gate
valves.
o When the ENERGY KING Wood/Coal

Boiler is in use, Valves #1 and #2 are open
and Valve #3 is closed.

o To isolate your ENERGY KING Wood/Coal

Boiler from the heating system when not in
use, close Valves #1 and #2 and open
Valve #3.

o Always remember to open Gate Valve #1

and #2 and close #3 when activating your
ENERGY KING Wood/Coal Boiler again.

Please refer to Appendix B for examples of

basic plumbing configurations.

Expansion Tank

All ENERGY KING Wood/Coal Boiler
installations must include an expansion tank to
allow water to expand or contract without
adversely affecting the system pressure.

Expansion tanks must be properly sized to
accommodate the water capacity of the
ENERGY KING Wood/Coal Boiler. When
installing the ENERGY KING Wood/Coal Boiler
as an add-on to an existing system, you need
not add a second expansion tank provided the
existing expansion tank can accommodate the
volume of both the ENERGY KING Wood/Coal
Boiler and the existing boiler. Consult your
plumber to verify your expansion tank is
properly sized.

Auto-Fill

In order for a pressurized hot water heating
system, such as the ENERGY KING
Wood/Coal Boiler, to function safely and
efficiently, it must be filled with water at all times
and must maintain a fairly constant pressure.
An auto-fill valve may be used for this purpose.
If you include an auto-fill valve in your
installation, be sure to choose one that is preset
for 12 to 15 PSI.

Note: If your system includes an auto-fill
feature, it will be more difficult to recognize
leaks because the auto-fill will constantly make
up lost water. It will also be difficult to
recognize if your boiler has overheated and
triggered the Pressure Relief Valve. Always be
sure to monitor your system for signs of leaks
or overheating.

Pressure Relief Valve

The Pressure Relief Valve must be plumbed

with a discharge tube that empties into a floor
drain.

Once installation is complete and you’ve filled
the boiler with water, verify the Pressure Relief
Valve’s proper functioning by manually opening
the valve and releasing water into the floor
drain. If no water flows, do not operate the
Boiler until a new Pressure Relief Valve is
installed.

The Pressure Relieve Valve will automatically
release water when the water pressure reaches
30 PSI. Be sure to monitor the water level in
your ENERGY KING Wood/Coal Boiler, and
refill when necessary. If your heating system
has an auto-fill feature, be sure the auto-fill
does not raise the water pressure above 15
PSI.

Temperature Relief Valve

In certain jurisdictions, a Temperature Relief
Valve may be required in addition to the
Pressure Relief Valve. For this reason,
ENERGY KING A40EK-D Wood/Coal Boilers
are equipped with a fourth receptacle, located
on the top of the Boiler. Consult your local
ENERGY KING dealer or plumber for possible
sources of Temperature Relief Valves
acceptable for use with your ENERGY KING
Wood/Coal Boiler.

Rev 08/24/10 ENERGY KING™ Wood/Coal Boiler Owner’s Manual  U. S. 20

Installation

Zones

A “heat dump” zone is required for all
installations. The purpose of this zone is to
circulate heated water away from the boiler
when no other zones are calling for heat. In
this way it will prevent your ENERGY KING
Wood/Coal Boiler from overheating. However,
as a safety feature, if your Boiler should
overheat or build up excess pressure, it will
trigger the pressure relief valve which will
release water, thus relieving pressure.

RJM Manufacturing, Inc. recommends installing
a normally open zone valve and a strap-on
(non-immersion, surface mounted) aquastat
(not included) as part of every dump zone valve
installation. Consult your local ENERGY KING
dealer or plumber for possible sources of
appropriate valves and strap-on aquastats
acceptable for use with your ENERGY KING
Wood/Coal Boiler.

In-floor Heating

To use the ENERGY KING Wood/Coal Boiler
with in-floor heating, a mixing valve may be
required to lower the water temperature before
it is delivered to your in-floor heating system.

Rev 08/24/10 ENERGY KING™ Wood/Coal Boiler Owner’s Manual  U. S. 21

Operation

General Instructions

● Do not operate with flue draft exceeding .06″ (14.95 Pa) of

water column.

● Do not operate with fuel loading or ash removal doors open.

● Do not store fuel or other combustible material within marked

installation clearances

● Inspect and clean flues and chimney regularly.

Please read this manual in its entirety prior to the first firing of your ENERGY KING Wood/Coal
Boiler. It is very important that you follow these suggestions and limitations in order to maintain your
warranty and to guarantee the long life of your ENERGY KING Wood/Coal Boiler.

The ENERGY KING Wood/Coal Boiler is
designed to burn for about 6 to 8 hours per load
of wood or coal. If the ENERGY KING heating
appliance is being fired hot constantly with full
flames and operating at only a 2 to 4 hour burn

cycle, it is being overfired. Your home heating

needs may be too great for the size of heating
appliance you have purchased. Forced firing or

abuse can be detected upon inspection and
will void your warranty.

Keep the Boiler and pipes in the heating system
filled with water at all times to reduce the

possibility of rust and corrosion. Never fire a

boiler that is low on water. The heating surface
can be damaged if the water level is too low.

Always add water to a boiler gradually. Never

add water to a hot appliance.

For greatest efficiency, you may sometimes
need to allow your existing conventional heating
system to assist your ENERGY KING

Wood/Coal Boiler in the coldest weather.

Risk of Fire:

CAUTION – Hot Surfaces: Keep children away!

Do not touch Boiler during operation.

Gate Valves

When plumbing into your existing heating
system, RJM Manufacturing, Inc. recommends
installing a series of three gate valves. The
three gate valves are to be used in the event
you do not use your Energy King Wood/Coal
Boiler for an extended period (one or more
weeks).

• When the ENERGY KING Wood/Coal
Boiler is in use, Valves #1 and #2 are open
and Valve #3 is closed.

• To isolate your ENERGY KING Wood/Coal
Boiler from the heating system when not in
use, close Gate Valves #1 and #2, and
open Valve #3.

• Always remember to open Gate Valves #1
and #2, and close #3 when activating your
ENERGY KING Wood/Coal Boiler again.

During the warmer seasons of spring and fall,
you should control the heat output by limiting
the amount of fuel, rather than the air supply.
Shorter, hotter fires will allow your ENERGY
KING Wood/Coal Boiler to operate at maximum
efficiency and with minimum emissions.

For best combustion efficiency, chimney
temperature should be 350-degrees F to
450-degrees F. RJM Manufacturing, Inc.
recommends installing a magnetic chimney
thermometer to monitor chimney temperature.

Operation

First Fire

Before lighting your first fire, inspect your
ENERGY KING Wood/Coal Boiler to ensure
that it has been properly installed and that all
safety requirements have been met. During
your inspection, pay particular attention to the
clearances to combustibles, venting, and
thermostat installation instructions.

Next, make sure that the burn chamber is clear
of all objects.

Do not fully load your ENERGY KING
Wood/Coal Boiler until you become familiar with
the operation of your ENERGY KING
Wood/Coal Boiler.

Verify the Pressure Relief Valve’s proper
functioning by manually opening the valve and
releasing water into the floor drain. If no water
flows, do not operate the Boiler until a new
Pressure Relief Valve is installed.

Some odors may be given off a new ENERGY
KING Wood/Coal Boiler during the initial few
hours of burning while the steel and the paint
are being cured. Ventilating the room until the
odors disappear is recommended.

Check to make sure that your combustion
blower is in proper working order. You can
check the forced draft blower by turning the wall
thermostat supplied with your ENERGY KING
heating appliance to a high temperature. If your
forced draft blower turns on, you may set the
wall thermostat to the desired setting.

Typical Operation Cycle

After a fire has been established and the operating temperature has been reached, only the wall
thermostat needs to be set to maintain the desired temperature. Your draft system is controlled
primarily by the wall thermostat; therefore it is crucial to ensure proper placement and installation of
the wall thermostat.

• When your home cools, the wall thermostat
located in the living area of the home
activates the combustion blower, forcing
combustion air into your burn chamber.

• When the thermostat is satisfied, it will
deactivate your forced draft control system,
allowing the fire to cool until the next time
your thermostat calls for heat.

• As the fire burns hotter, the temperature of
your heating water increases and activates
your circulation system to deliver heat to your
home.

Your ENERGY KING Wood/Coal Boiler can run efficiently over extended periods of time and at
different heat output levels as long as the fuel supply is uninterrupted and cleaning and
maintenance are performed routinely.

Rev 08/24/10 ENERGY KING™ Wood/Coal Boiler Owner’s Manual  U. S. 23

Operation

Overfire

Do not overfire. Using too much wood or coal,

burning trash in the Boiler, or operating with a
flue draft that exceeds .06 inches water
column, may result in overfiring—a dangerous
condition which could produce excessive heat
and pressure within the ENERGY KING
Wood/Coal Boiler, or could ignite creosote
within the chimney or Boiler. Forced firing or

abuse can be detected upon inspection and will
void your warranty.

Power Failure Instructions

If operated during a power failure, your ENERGY KING Wood/Coal Boiler could overheat, creating
a possible hazard and may result in property damage or bodily injury. Do not operate the ENERGY

KING Wood/Coal Boiler during a power failure - this can be dangerous and will void your warranty.

After power is restored, verify that there is power to the ENERGY KING Wood/Coal Boiler, and

restart using the procedures described in Starting a Fire.

Do not operate the ENERGY KING

Wood/Coal Boiler during a power failure.

As a safety feature, if your Boiler should
overheat, it will trigger the pressure relief valve
and release water to relieve pressure. If this
should occur, allow the Boiler to cool

completely before refilling. Never fire a boiler
that is low on water. Never add water to a hot

boiler.

Operation

BURN AIR-DRIED WOOD, OR ANTHRACITE OR BITUMINOUS COAL ONLY

All home chimneys and hookups are different. After a few fires, you will find the best way to start a
fire in your ENERGY KING Wood/Coal Boiler.

You will get the best efficiency when you add only the amount of coal needed for a 6 to 8 hour burn.
A full load is not always the best solution for your needs.

Burning Coal

Burning coal will provide a lesson in patience.
Take the time necessary to experiment and
understand the operation of your ENERGY
KING Wood/Coal Boiler.

Please keep the following points in mind
when burning coal:

1. A Barometric draft control in the chimney

connector must be used when burning

coal.

2. Never completely cover the live fire with

fresh coal. Always leave a generous area
of burning coal at the top and rear of the
fire.

3. Always keep the ash pan clean. Coal firing
produces much more ash than wood.
These ashes must be removed often
(possible daily) in order to avoid piling up
too closely to the grates.

Removal of the coal ash will allow for
passage of primary air to the coal bed and
prevent damage or warpage to the grates.

Dispose of ashes with care:

Ashes should be placed in a metal
container with a tight fitting metal lid.
The closed container of ashes should
be placed on a noncombustible floor
or on the ground, well away from all
combustible materials, pending final
disposal.

All coal contains small amounts of
dangerous elements. Therefore it is
essential that your coal ash be
disposed of in municipally designated
areas.

4. A coal fire should not be poked or broken
up, as this tends to bring ash to the surface
of the coal bed where it may fuse. If the
ash fuses, clinkers will form. It may be
necessary to remove all unburned material
and ash from the burn chamber to remove
the clinkers. These should be carefully
removed using tongs, and always put into
an airtight metal container.

5. If the fire goes out or does not hold
overnight, check for the following:

a. Poor Draft

b. Incorrect damper settings.

c. Improper firing methods for the coal

being used.

d. Coal is not sized to the boiler (see Fuel

Requirements – Coal).

e. Ashes, if allowed to accumulate in the

ash pan, will not allow the passage of
required air for combustion. Keep the
ash pan clean.

Operation

Starting a Coal Fire

1. Pull the sliding smoke baffle (located above
the fuel loading door) out to open.

2. Place a small amount of crumpled paper in
the center of your ENERGY KING
Wood/Coal Boiler. Crisscross a couple of
handfuls of dry, 3/4″ thick kindling wood,
then several small pieces of firewood. Wait
until the wood fire is established with hot, red
embers before adding coal.

3. It will take 5 to 10 minutes for the wood fire

4. After the coal fire is established and spread

5. Push in the sliding smoke baffle after loading

6. The burn time is controlled by the 24-V Wall

Check the fire periodically to make sure it is
spreading throughout the coal bed.

Be sure the sliding smoke baffle

is full

to establish itself. Once you have some red­hot burning embers, add several small
shovels of coal over the wood coals until you
have a 2″-3″ bed of burning coals. Be sure to
give each small layer about 5-10 minutes to
ignite before covering it with the next layer of
coal.

throughout the burn chamber, gently shake
the grate until ashes fall in the ash removal
pan. Add larger amounts of coal to build up
the coal bed.

Never overload your burn

chamber. Do not load coal above

the top of the firebrick.

your ENERGY KING Wood/Coal Boiler and
your fire is established.

Thermostat and the forced air draft controls
on the Boiler. Allow your ENERGY KING
Wood/Coal Boiler to operate with draft
controls fully open for approximately 15
minutes or until the fresh coal ignites. When
the coal is properly ignited, adjust the
thermostat accordingly.

Refueling / Recharging

To refuel/recharge the anthracite coal fire in
your ENERGY KING Wood/Coal Boiler:

1. Pull the sliding smoke baffle out.

2. Gently shake the grates down

3. Open the fuel loading door slowly: open the
door about 1″-2″ then wait about 15 to 20
seconds before opening fully.

When recharging, fresh coal tends
to give off large quantities of
volatile gas which may accumulate
and possibly ignite, causing a
backpuff. Always open the fuel
loading door slowly to prevent
backpuffing.

Never stand in front of the fuel

loading door when refueling;

4. If the coal fire has died down before
recharging, a fresh supply of kindling will
need to be added. Only add fresh coal to a
deep, hot bed of coals.

5. Spread fresh coal evenly over existing coal,
leaving some hot coals exposed in the
center of the burn chamber. Be careful not to
smother your existing coals.

6. Close the fuel loading door and sliding
smoke baffle.

always stand to the side.

Never overload your burn

chamber. Do not load coal above

the top of the firebrick.

Rev 08/24/10 ENERGY KING™ Wood/Coal Boiler Owner’s Manual  U. S. 27

Operation

Bituminous Recharging

Because bituminous coal has higher sulfur
content, bituminous recharging is slightly
different from anthracite recharging.

To refuel/recharge the bituminous coal fire in
your ENERGY KING Wood/Coal Boiler:

1. Pull the sliding smoke baffle out.

2. Gently shake the grates down

3. Open the fuel loading door slowly: open the
door about 1″-2″ then wait about 15 to 20
seconds before opening fully.

When recharging, fresh coal tends
to give off large quantities of
volatile gas which may accumulate
and possibly ignite, causing a
backpuff. Always open the fuel
loading door slowly to prevent
backpuffing.

Never stand in front of the fuel

loading door when refueling;

4. If the coal fire has died down before
recharging, a fresh supply of kindling will
need to be added. Only add fresh coal to a
deep, hot bed of coals.

5. Push the hot coals to the rear of the burn
chamber and position fresh coal on the grate
in front of the banked coal. Be careful not to
smother your existing coals.

6. Close the fuel loading door and sliding
smoke baffle.

always stand to the side.

Never overload your burn

chamber. Do not load coal above

the top of the firebrick.

Banking

Banking allows you to recharge your coal fire in
such a manner as to retain a hot coal bed
throughout the night.

Approximately one hour before retiring for the
night, push the coals to the rear of the burn
chamber with the coal tapered down in the
front.

Be careful not to smother your existing coals.

Never overload your burn

chamber. Do not load coal above

the top of the firebrick.

Rev 08/24/10 ENERGY KING™ Wood/Coal Boiler Owner’s Manual  U. S. 28

Maintenance

Periodic maintenance is required to continue the performance of your ENERGY KING Wood/Coal
Boiler. As with any solid-fuel heating appliance, the need for and frequency of cleaning depends on
the amount and quality of fuel burned, the quality of the fire, and the length of time since the last
cleaning. Weekly cleaning may be required in warmer weather, whereas monthly cleaning may be
enough in colder weather.

Before the first fire of each new heating season, check all installations and accessories to ensure a
safe burning process.

Creosote – Formation and Need for
Removal

When wood is burned slowly, it produces tar
and other organic vapors, which combine with
expelled moisture to form creosote. The
creosote vapors condense in the relatively cool
chimney flue of a slow-burning fire. As a result,
creosote residue accumulates on the flue
lining. When ignited, this creosote makes an
extremely hot fire, the results of which can be
tragic.

Check daily for creosote build up until
experience shows how often cleaning is
necessary. The chimney connector and
chimney should be inspected at least twice
monthly during the heating season to
determine if a creosote buildup has occurred. If
creosote has accumulated, it should be
removed to reduce the risk of a chimney fire.

Be aware that the hotter the fire, the less
creosote is deposited, and that weekly cleaning
may be necessary in mild weather, even
though monthly cleaning may be enough in the
coldest months.

Have a clearly understood plan to handle a
chimney fire.

Risk of electric shock. Disconnect power at the service
panel or breaker box before servicing ENERGY KING
Wood/Coal Boiler.

Keep the area around the ENERGY KING Wood/Coal
Boiler clean and free of dust and debris.

Disposal of Ashes

Ashes should be placed in a metal container
with a tight fitting metal lid. The closed
container of ashes should be placed on a
noncombustible floor on the ground, well away
from all combustible materials, pending final
disposal.

If the ashes are disposed of by burial in soil or
otherwise locally dispersed, they should be
retained in the closed container until all ash
and cinders have thoroughly cooled. Do not
place any other waste materials in this
container.

All coal contains small amounts of dangerous
elements. Therefore it is essential that your
coal ash be disposed of in municipally
designated areas.

NOTE: EMBERS REMAIN HOT FOR

MANY DAYS. STORE IN A SAFE PLACE

Never use a conventional vacuum cleaner or a
shop vacuum to remove ashes from a solid-fuel
heating appliance. Ashes remain hot for many
days, and when trapped in a conventional
vacuum can cause a fire hazard. Only use a
vacuum designed for the safe cleaning and
removal of ashes.

AWAY FROM COMBUSTIBLES.

Rev 08/24/10 ENERGY KING™ Wood/Coal Boiler Owner’s Manual  U. S. 29

Maintenance

Gasket Replacement

The cast iron fuel loading and ash removal doors of your ENERGY KING Wood/Coal Boiler are
equipped with gaskets to ensure safe operation and an airtight seal. When these gaskets become
worn or damaged, you will need to replace them.

To replace the gaskets you will need 3/4-inch, high temperature rope gasket, available from your
ENERGY KING dealer or hardware store.

1. Remove the door and lay it face down on a

clean, flat surface.

2. Find the ends of the gasket and pull it off.

3. Using a screwdriver, remove any excess

gasket cement from the gasket channel.

4. If desired, a small drop of gasket cement

may be applied to the corners of the gasket
channel.

5. Lay the new door gasket in the channel,

cutting off any excess gasket rope.

Figure 11: Door Gasket

6. Reattach the door. If gasket cement was

applied, keep the door closed until the
cement has fully dried.

Routine Maintenance

Please use the following timeline as a guide for determining how much maintenance your ENERGY
KING Wood/Coal Boiler requires to operate at peak performance. Failure to clean and maintain this
Boiler as indicated can result in poor performance and safety hazards.

Please use Appendix D: Purchase & Service Record to keep a record of your maintenance and

service practices. In the event of a warranty claim, we may request a copy of this record.

Daily

Until a pattern of cleaning requirement is
established, inspect and, if necessary, clean the
following components daily:

• Fuel Supply, refilling as necessary.

• Water level, refilling as necessary.

• Flue Pipes, including joints and seals, should

be inspected to ensure that smoke and flue
gases are not drawn in and circulated by the
air-circulation system.

• The ash removal pan should be emptied and
cleaned regularly. Ash content is a good
indicator of fuel efficiency and quality. High
quality fuel will produce less ash and fewer
clinkers than lower quality fuel. Never allow
ash to build up to the level of the grates.

Inspect flue pipes, joints and seals regularly to ensure that
smoke and flue gases are not drawing into the home.

Every 2 – 3 Days / Weekly

Once a pattern of cleaning requirement is
established, the following components should
still be monitored on a regular basis:

• Burn chamber

• Ash removal pan

• Water Level

• Flue pipes, joints and seal

Rev 08/24/10 ENERGY KING™ Wood/Coal Boiler Owner’s Manual  U. S. 30

Maintenance

Monthly

The water level on your ENERGY KING
Wood/Coal Boiler should be monitored on a
regular basis and refilled when necessary.

Seasonally / Every 3 Months / After

every 1 – 2 Tons of fuel burned

Until you are familiar with how ash and creosote
accumulate with your operating practices, we
recommend inspecting your ENERGY KING
Wood/Coal Boiler at least once per ton of fuel
burned. Particular attention should be given to:

• Draft Control system (blowers, etc.)

• Gaskets (Fuel Loading and Ash Removal

Doors)

• Water Level

• Fresh air intake

• Chimney

Spring Shutdown

Cleaning the flue pipe and chimney is especially important
at the end of the heating season to minimize corrosion
during the summer months caused by accumulated ash.

Annually

At least once each year:

• Verify the Pressure Relief Valve’s proper
functioning by manually opening the valve
and releasing water into the floor drain. If
no water flows, do not operate the Boiler
until a new Pressure Relief Valve is
installed.

• Inspect the Boiler and plumbing for leaks.

• Verify the proper operation of all pumps

and valves.

It is important to give the entire ENERGY KING Wood/Coal Boiler a thorough cleaning:

• Your venting system should be inspected
and cleaned annually. Clean and remove fly
ash from chimney connector, flue pipes and
chimney. Soot buildup should be removed to
prevent the risk of a chimney fire and to
minimize corrosion during the summer
months.

Failure to clean and maintain this heating appliance as indicated can result in poor performance
and safety hazards.

Please use Appendix D: Purchase & Service Record to keep a record of your maintenance and

service practices. In the event of a warranty claim, we may request a copy of this record.

Remember: A clean appliance burns efficiently and will remain trouble free!

• Scoop out any unburned fuel from the burn
chamber, and empty and clean the burn
chamber and ash removal pan.

○ Do not allow fuel or ash to sit in the

ENERGY KING Wood/Coal Boiler over the
summer months. Fuel and ash can
accumulate moisture over the summer
months having a corrosive effect on metal
and cast iron parts, and causing the fuel to
mold.

decrease each year until the maximum life of the warranty exhausts any replacement value. Replacement value

pressure temperature gauge.

What is covered by this warranty?

This warranty covers any defects in materials or workmanship in your new ENERGY KING solid-fuel heating
appliance.

What is not covered by this warranty?

This limited warranty does not apply:

• If your appliance has not been installed, operated and maintained in strict accordance with instructions provided

in the Installation, Operation and Maintenance Manual.

• If any part has been damaged in shipment, modified, altered, tampered with, abused, or has been subject to

accident or misuse.

• If your appliance has been altered or repaired in a manner which, in our sole judgment, affects its performance,

stability or reliability.

• If parts not made or supplied by us have been used in connection with the appliance, if in our sole judgment,

such use affects its performance, stability or reliability.

warranty.

our judgment are expendable, replaceable or wear items.

installation and venting or ducting of the appliance.

We are not responsible for installation and will not be liable in any respect under the terms of the warranty for injury
or damage to the building structure in which the appliance has been installed, or to the person or persons and
property therein, arising out of the use, or installation of the ENERGY KING appliance. The appliance must be
installed in compliance with the local, state and national building and fire codes and regulations, and in strict

number, serial number and model number of the appliance, date of purchase, name and address of installer and a

Disclaimer of Implied Warranties & Consequential Damages

Our obligation under this limited warranty, to the extent allowed by law, is in lieu of all warranties, implied or
expressed, including implied warranties of merchantability and fitness for a particular purpose and any liability for
incidental and consequential damages with respect to the sale or use of the items warranted. Such incidental and
consequential damages shall include but not be limited to: transportation / freight charges, cost of installation, duty,
taxes, charges for service or adjustment, loss of income, rental or substitute equipment, and expenses due to loss,
damage, detention or delay in the delivery of equipment or parts resulting from acts beyond our control.

Some states do not allow the exclusion or limitation of incidental or consequential damages, or limitation of implied
warranties, so the limitations or exclusions in this limited warranty may not apply to you.

It is your responsibility to ensure that the appliance is installed in compliance with local, state and federal
building and fire codes regulating installation and inspection.

It is your responsibility to complete the warranty card and return it to the address indicated within 30 days of
the purchase. You must also keep your receipt as proof of date of purchase. Failure to do so will mean that
you may not later make a claim under this warranty.

It is your responsibility to read the Installation, Operation & Maintenance Manual and to install, operate and
maintain the appliance in accordance with all instructions and safety procedures. Failure to do so is a misuse
of the appliance.

It is your responsibility to inspect the appliance and to have any part(s) repaired or replaced when continued
operation would cause damage or excessive wear to other parts or cause a safety hazard.

It is your responsibility for any cost incurred by the distributor/dealer for travel to or transportation of the
product for the purpose of performing a warranty obligation or inspection.
