Installation
Plumbing
ENERGY KING A40EKB 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 35EKB/45EKB 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 A40EKB 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.
