3. HEATMOR™ Inc. recommends a licensed professional electrician make all the
necessary electrical connections involved with the installation of the furnace.
4. Always disconnect the HEATMOR™ Outdoor Furnace from the main electrical supply
before servicing any of the electrical components of the HEATMOR™ Outdoor Furnace.
5. Always disconnect any existing electrical connections to any in-house heating system,
before installing the outdoor furnace to any existing indoor heating system or appliances.
6. The red wire from the high-limit aquastat on the back of the HEATMOR™ should
be wired to a 120v indoor temperature control to override the thermostat. This will
dissipate excess heat in the event of a possible malfunction with the HEATMOR™.
The red wire is capped off in the electrical junction box when the HEATMOR™ is
new.
Other
1. The unit may be connected to an existing indoor boiler system by installing a water-to-water heat exchanger.
2. HEATMOR™ INC. recommends that you contact a licensed professional plumber to
make all necessary plumbing installations between the HEATMOR™ furnace and the
existing heating system of your building(s).
3. Do not operate the HEATMOR™ furnace until all electrical and water line connections
have been properly installed and tested.
4. Do not allow any re in the rebox until the HEATMOR™ has the correct amount of
water and sand installed.
5. DO NOT OVER-FIRE THIS HEATER. Attempts to achieve heat output rates that ex-
ceed heater design specications can result in permanent damage to the heater and
to the catalytic combustor if so equipped.
13
X-Series Pad Specications
Chapter 6
The actual pad size is 50" x 88". This
gives approximately 2" extra on all sides of
furnace.
CAUTION: Do not exceed this length
measurement. Overall width may exceed
measurements if desired.
The bottom of the loading door is 24" above
ground or base of furnace. If you desire to
have the leading door higher, you can do so
by making the pad depth thicker.
Example: 12" instead of 4" or any gure in
between.
Patio stones or separate cement pad in
front of the loading door should NOT be
attached to main base of furnace.
It is recommended to use steel mesh or
rebar in pad for strength.
Benets to raising the pad:
1. Gives space below the ash auger
to place a pail for convenient ash
removal.
2. Allows better visibility of the rebox.
3. Less bending when adding wood.
4. Keeps exhaust above the operator.
5. Protects the base of the HEATMOR™
14
Chapter 7
INSTALLATION OF THE HEATMOR™ FURNACE
Installation should be performed by a qualied installer and will comply with all the requirements of the authority having jurisdiction over the installation.
Principles
1. Need to have an airtight seal between the concrete base and the perimeter of the
rebox base.
2. Need to seal the perimeter of the entire HEATMOR™ so rodents are not able to nd a
home inside the HEATMOR™.
3. Need to lift the HEATMOR™ without damaging it.
Equipment Required
1. It is NOT possible to lift a HEATMOR™ with the forks
of a forklift under the HEATMOR™. It MUST BE
LIFTED FROM THE TOP, by the lift hook. A crane or
heavy backhoe works best, although a heavy duty
farm tractor is acceptable.
a. With a farm tractor, extreme care must be taken
to prevent the HEAMTOR™ from swinging and
causing damage to the HEATMOR™.
Placing the HEATMOR™ on the Concrete Base
2. Before setting the HEATMOR™ onto the concrete
base, it is a good idea to place a solid sheet of the
proper “reective air foil” (also called bubble foil)
between the concrete and the HEATMOR™. This will
absorb ridges in the concrete and make it easier to
apply caulking around the inside perimeter of the base
of the HEATMOR™. This reective foil will also reect escaping heat up into the sand,
and help prevent air leaks into the rebox if cement cracks.
3. Make sure the total area of the base (where the sand is going) is on solid concrete. Do
not let the base extend past the hole in the concrete where the lines come in.
4. After the HEATMOR™ is in place perform the following:
Caulking around the Firebox Base
a. One person should get into the HEATMOR™.
b. Apply a substantial bead of caulking around the entire inside perimeter
of the base. This will give an airtight seal so no air will seep through the
sand. This should require about three tubes of High Temperature
Silicone.
Caulking around the Outside Perimeter of HEATMOR™
c. With a sharp knife, trim any excess bubble foil that extends past the
base of the HEATMOR™.
d. Apply a bead of caulking around the entire outside perimeter of the
HEATMOR™ to seal out rodents.
15
FILLING THE HEATMOR™ OUTDOOR FURNACE INITIALLY
WITH WATER
Before your HEATMOR™ furnace with water, all plumbing connections at the back of the
HEATMOR™ furnace, all electrical hookups, and all heating appliances should be installed
and tested for possible leaks.
HEATMOR™ suggests the use of brass ttings when installing the unit.
NOTE: If you have any questions regarding installation of the furnace or any aspect of
installation, contact your local dealer.
NOTE: Never start a re inside the rebox until the water jacket is full of water and sand
has been added to the base to the correct level.
1. Close the bladder gate valve located at the front of the HEATMOR™ furnace.
2. This valve will ensure no water can enter the bladder.
3. Close the bottom supply line valve at this back of the
HEATMOR™.
4. Open the top return line valve at the back of the
HEATMOR™.
5. Ensure the vent pipe is unobstructed. If equipped with a pop-
off ball on the roof of the furnace, remove it from the relief
vent pipe.
6. Connect the water source to the return line leading to the
HEATMOR™. Use a garden hose to add the water to the
return line.
7. Turn on the source of water.
8. The pressured water will now ow through and remove the
air out of the return line as the wter ows into the
HEATMOR™.
9. Continue adding water until water ows out the relief vent
pipe onto the roof of the HEATMOR™.
10. Turn off the source of water.
The HEATMOR™ is now full of water and the return line is also full of water and air free,
BUT the supply line leading from the HEATMOR™ to the building to be heated is still full
of air.
11. Close the top return line valve at the back of the HEATMOR™.
12. Remove the garden hose that was used to deliver the source of water from the top
return line, BUT leave the garden hose valve open.
13. Open the bottom supply line at the back of the HEATMOR™ (bottom). The pressure
of the water in the HEATMOR™ will now force water from the HEATMOR™ through
the supply line back into the building to be heated. This water will soon discharge
from where the garden hose was connected. When there is a steady stream of water
owing, the air will be removed from that supply line. Usually it requires the removal of
approximately ve gallons of water to ensure the line is air-free.
Bladder Gate Valve
16
FILLING THE HEATMOR™ OUTDOOR FURNACE INITIALLY
WITH WATER
NOTE: The circulator pumps cannot “push” much air through a system. They are designed
to move water not air.
14. Start the circulating pump. Remember to properly bleed air from the pump.
ABSOLUTELY NO FIRE IN THE FIREBOX WHEN PERFORMING THIS PROCEDURE.
DO NOT PERFORM THIS PROCEDURE WHEN UNIT WATER TEMPERATURE IS
UNSAFE. ALWAYS WEAR PERSONAL PROTECTIVE EQUIPMENT WHEN WORKING
Maintaining the Correct Amount of Water in the Bladder and in the HEATMOR™
1. Close the bladder gate valve located at the front of the HEATMOR™ furnace. Closing
this valve will ensure no water can enter the bladder.
2. Remove the pop-off ball (if equipped) from the relief vent pipe.
3. Connect the water source to the return line leading to the HEATMOR™. Use a garden
hose to add the water to the return line.
4. Turn on the source of water, but only about half a full ow.
5. The pressured water will now ow through the return line as the water ows into the
HEATMOR™.
6. Continue adding water until water ows out the relief vent pipe, onto the roof of the
HEATMOR™, leave the water running. Some may continue to spill out onto the roof.
7. Place the pop-off ball (if equipped) back onto the relief vent pipe.
8. Turn on the green bladder gate valve and let the bladder ll half full. You can check
this by felling the bladder with your hand inserted through the bladder inspection cover
plate.
9. Turn off the water when the bladder is half full.
Low Water Condition
If the water level is below the bladder port when the water heats up, air will enter the
bladder instead of water. To remove the air from the bladder, follow steps 1 through 7 above
and make sure there is a good seal on the pop-off ball (if equipped). Next:
1. Open the bladder gate valve.
2. CAREFULLY remove the bladder hose, allowing the bladder to empty its contents.
3. After bladder is empty of air/water, re-attach the bladder hose to the bladder gate
valve and tighten the hose clamp.
WITH WATER AND CHEMICALS.
Next, follow steps 7-9 above.
NOTE: Never light a re inside the rebox until the water jacket is full of water and sand
has been added to the base to the correct level.
Installation should be performed by a qualied installer and will comply with all the requirements of the authority having jurisdiction over the installation.
READ THROUGH THE ENTIRE OPERATIONS AND MAINTENANCE MANUAL BEFORE
OPERATING YOUR HEATMOR™ STAINLESS STEEL OUTDOOR FURNACE.
17
Initial Installation of Sand
Types of Sand to Use
1. Sand that does not contain clay, rocks or organic matter is appropriate. Use a sand
that when packed will not allow air to pass through. Mortar sand or sand that is used in
the redi-mix concrete business is good. Never use gravel.
2. 200X requires approximately 0.18 cubic yards.
3. 350X requires approximately 0.28 cubic yards.
Installation
1. Cover the grates with a piece of cardboard.
2. One person enters the rebox.
3. Another person shovels the sand into the
rebox while the person inside packs the sand
completely, using a piece of wood like a 2" x 4"
x10" long.
4. Fill the base with sand, level to the top of the
grates.
Open Bottom without Sand
NOTE: Never light a re inside the rebox until the water jacket is full of water and sand
has been added to the correct level in the base.

1. Never open the rebox door if the combustion air blower is operating or if you suspect
a roaring hot re inside the rebox.
2. Never open rebox door immediately after the combustion air blowers have shut off.
If the water temperature is very close to the high setting, you should assume the air
combustion fans have just shut off.
3. If there is more than a ‘whiff’ of exhaust coming from the chimney and the draft fan is
off, do not open the rebox door for at least two minutes. The burn cycle would heave
just ended and the rebox will be full of unburned gases (exhaust) that may ignite
when fresh air is introduced.
4. Load the unit with wood carefully, but quickly. After loading wood make sure all debris
is cleaned from the rebox door frame and gasket. Then close rebox door securely.
5. Keep the rebox door, ash auger tube cover cap, top ue cover plate, and the outer
door of the HEATMOR™ furnace closed at all times except for servicing and refueling.
6. Keep the locking handle on the outer door locked at all times when not servicing or
refueling to reduce the risk of tampering and possible injury.
7. Never add water to the HEATMOR™ furnace if the internal water temperature is over
212˚ Fahrenheit. Failure to adhere to this warning may cause a steam ash and result
in an explosion.
8. Do not store combustible liquids or materials near the outdoor furnace. Adhere to the
“Clearance to Combustibles” guildelines.
9. Never use gasoline, kerosene, charcoal, lighter uid or similar liquids to start, restart
or freshen up a re. Using such liquids may result in severe burns and injures.
10. When adding water, water treatment or maintaining the HEATMOR™ furnace,
protective clothing must be worn at all times.
11. Never leave the HEATMOR™ furnace unattended while the rebox door is open or
unlatched.
12. Stay clear of any exhaust emitting from the rebox.
13. Do not burn garbage, plastics, rubber naphtha, trash, tires, solvents, engine oil,
gasoline, leaves, paper products, cardboard, material treated with petroleum products
(particleboard, railroad ties and pressure treated wood) or other inappropriate
materials.
