CHAPTER 8
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 lifting 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 HEATMOR™ 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
Lift Hook
17
Filling the HEATMOR™ Outdoor Furnace Initially with Water
Before lling 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.
If you have any questions regarding installation of the furnace or any aspect of installation,
contact your local dealer.
Note: Never start a fire inside the firebox 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. This valve will ensure no water
can enter the bladder.
2) Close the bottom supply line valve at the back of the
HEATMOR™.
3) Open the top return line valve at the back of the
HEATMOR™.
4) Remove the pop off ball if equipped on the roof of the
stove from
the relief vent pipe. (If so equipped)
5) Connect the water source to the return line leading to the
HEATMOR™. Use a garden hose to add the water to the
return line.
6) Turn on the source of water.
7) The pressured water will now ow through and remove the
air out of the return line as the water ows into the HEATMOR™.
8) Continue adding water until water ows out the relief vent pipe,
onto the roof of the HEATMOR™.
9) 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.
10) Close the top return line valve at the back of the HEATMOR™.
11) 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.
12) 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.
NOTE: The circulator pumps cannot “push” much air through a system. They are
designed to move water not air.
13) Start the circulating pump. Remember to properly bleed air from the pump.

ABSOLUTELY NO FIRE IN THE FIREBOX WHEN PERFORMING THIS REPAIR.
DO NOT PERFORM THIS REPAIR WHEN UNIT WATER TEMPERATURE
IS UNSAFE. ALWAYS WEAR PROPER PERSONAL PROTECTIVE
EQUIPMENT WHEN WORKING WITH WATER AND CHEMICALS.
Maintaining the Correct Amount of Water in the Bladder and in the HEATMOR™
1) Keep your bladder valve closed when lling your stove with water, but open at all
other times. Your bladder should have a small amount of water in it.
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 step 1 above and make
sure there is a good seal.
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.
Next, follow step 1 above.
NOTE: NEVER LIGHT A FIRE INSIDE THE FIREBOX 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 QUALIFIED 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.

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) Model 100 furnaces require approximately 0.18 cubic yards, Model 200 – 0.25
cubic yards, and Model 400 – 0.38 cubic yards of sand.
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 x 10 inches long.
4) Fill the base with sand, level to the top of the
grates.
NOTE: NEVER LIGHT A FIRE INSIDE THE FIREBOX UNTIL
THE WATER JACKET IS FULL OF WATER AND SAND HAS
BEEN ADDED TO THE CORRECT LEVEL IN THE BASE.

CHAPTER 9
SAFE FURNACE OPERATION GUIDELINES
OPERATION
HEATMOR™ OUTDOOR FURNACES, MODEL 100 CB, 200 CB, AND 400 CB ARE
CERTIFIED TO BURN WOOD AND APPROVED COAL ONLY. CONTACT HEATMOR
FOR APPROVED COAL TYPES.
Burning of other materials may result in serious burns, health consequences, or damage to
this furnace and other components of the heating system and may void warranty.
***IMPORTANT NOTICE***
PLEASE REFER TO “FILLING YOUR HEATMOR™ FURNACE WITH LOADING COAL
INTO THE HEATMOR™,” FOR ADDITIONAL SAFE LOADING PROCEDURES.
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 “wiff” of smoke 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 have
just ended and the rebox will be full of unburned gases (smoke) that may ignite when
fresh air is introduced.
4) Load the unit with coal carefully, but quickly. After loading coal make sure all debris
is cleaned from the rebox doorframe 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 degrees Fahrenheit. Failure to adhere to this warning may cause a steam
ash and result in an explosion.
21
8) Do not store combustible liquids or materials near the outdoor furnace. Adhere to
the “Clearance to Combustibles” guidelines.
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 injury.
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 smoke emitting from the rebox.
13) Do not burn garbage, tires, solvents, engine oil, gasoline, or other inappropriate
materials.
14) Store ashes outside, in a metal container with a metal tight tting lid, away from
the outdoor furnace and other buildings. No other waste should be placed in this
container.
15) Wear a particle mask when removing ashes.
16) Ash auger may be hot after removing ashes.
17) In case of power failure, do not open any doors on the HEATMOR™. Monitor the
water temperature very closely. Refer to “freeze protection” in this manual.
18) In below freezing weather, if the water temperature in the HEATMOR™ drops
below 40 degrees Fahrenheit, drain all water from the HEATMOR™ immediately (if
there is no anti-freeze in your system).
19) Water additives supplied with a HEATMOR™ do not give any freeze protection.
20) Always remove the weighted pop off ball before removing more than 5 gallons of
water from the HEATMOR™.
21) Check daily for creosote buildup until experience shows how often cleaning is
necessary.
22) Be aware that the hotter the re, the less creosote is deposited, and that weekly
cleanings can be necessary in mild weather, even though monthly cleanings can be
enough in the coldest months.
22
Lighting the HEATMOR™ for the First Time
When lighting the HEATMOR™ furnace for the rst time, all installations must be complete
and the furnace must be full of water. It is recommended to open bladder valve, and then
build re to bring the water up to temperature.
The lighting process is fairly simple. Please use the following steps simply as a guideline or
contact your local dealer for further instruction. Read the entire manual before lighting,
so you have a complete working knowledge of the furnace. Ask for a demonstration
from your local dealer. It is very important to fully educate all persons who will be
lighting and fueling the HEATMOR™ furnace.
PLEASE READ THROUGH ALL “LIGHTING YOUR HEATMOR™” STEPS BEFORE
LIGHTING YOUR FURNACE.
1) Close the green valve, supplying the bladder, located at the front of the stove.
2) Ensure that the furnace is full of water by running ve gallons of water onto the
roof of the HEATMOR™.
3) Ensure that there is 115-volt electrical power supplying the HEATMOR™ furnace.
4) Place some small pieces of wood (ve pounds) with paper into the rebox.
5) Place a few larger pieces of wood (20 pounds) on top of the smaller pieces.
6) Light the re.
7) Leave the re box door partially open to allow the re to start burning. The rebox
door should only need to be open about two inches. At this point the smoke should go
up the chimney and not out the rebox door.
8) Once the re is burning rather briskly, close the re box door and turn off the light
switch which in turn will make the combustion air blower(s) operate.
9) Operate the blowers for approximately 10 minutes.
10) Turn off the blowers.
Wait a few seconds to allow the combustion to decrease.
11) Open the rebox door and add a substantial amount of coal to the rebox.
12) Turn on the blowers.
13) Securely close the rebox door and outer door.
NOTE: Before the furnace is red up, the furnace is lled with water. While the furnace is
lling with water, the bladder is shut off to prevent excess water into the bladder, preventing
over ll. When the furnace is freshly lled the water temperature is approximately 50
degrees Fahrenheit. When the furnace is full of water you will notice water coming out
onto the roof from the relief vent pipe. At this point the water should be turned off and
the bladder valve opened. After the furnace is red up, the water temperature will start to
increase. While the water temperature rises, the water will expand as it heats up, causing
the excess water to go into the bladder. It will go into the bladder because it is the place
of least restriction. This is another reason why we do not ll the bladder initially, too much
water in the bladder at cooler temperatures could cause the bladder to overll at higher
temperatures caused by the expansion of the water during temperature rise.
23
DEW POINT
NOTE: As the temperature inside of the rebox is increasing, there will be some sweating
inside the rebox. There may be streams of water running down the inside rebox walls and
down the inside of the rebox door. Water may run out onto the fan cover, below the rebox
door, and even out the auger tube. THE HEATMOR™ IS NOT LEAKING!
Just as moisture collects on the inside of a warm house window on a cold outside day, the
same thing is occurring inside the HEATMOR rebox. The warm moisture in the smoke is
condensing on the cold rebox walls of the HEATMOR. In most typical situations, once the
water temperature is above approximately 130 degrees Fahrenheit, the sweating will stop
because you are above the dew point.
