SAFETY
WARNING: If this furnace is not properly installed, a house
fire may result. For your safety, follow the installation
directions. Contact local building or fire officials about
restrictions and installation requirements in your area.
NOTE: We strongly recommend installers to be WETT or
WHERF certified.
To ANYONE using this furnace:
3. DO NOT use gasoline type lantern fuel, kerosene, charcoal
lighter fluid or similar liquids to start or freshen up the fire in
this furnace. Keep all such liquids well away from the furnace
while it is in use.
4. DO keep the furnace door shut at all times when a fire is
burning. Open the door only to load or check the fire.
5. When checking or loading wood into the fire, DO pull open
the bypass lever first, then open the door very slowly.
6. DO keep all combustible materials (firewood, shoes etc.) at
least 18 inches away from the furnace.
These DO's and DO NOT's are for your safety.
1. DO read this instruction manual before lighting your first
fire.
2. DO burn seasoned wood fuel only. DO NOT burn:
- driftwood (salt corrosion is not a warranty item)
- treated wood
- coal
- garbage
- plastic
Also DO NOT use construction scraps (e.g., 2x4 or plywood
scraps) as your only supply of fuel, as you may overheat and
seriously damage the furnace.
7. Do not use a grate or elevate the fire.
CREOSOTE
When wood is burned slowly, it produces tar and other
organic vapours, which combine with expelled moisture to
form creosote. The creosote vapours condense in the relatively cool chimney flue of a slow burning fire. As a result,
creosote residue accumulates in the flue lining. When ignited,
this creosote makes an extremely hot fire.
A chimney fire occurs when creosote in the chimney
ignites, usually when the furnace is turned up high after a
period of low burn.

Furnace Operation
The chimney should be inspected periodically during the
heating season to see if a creosote build-up has occurred. If a
significant layer of creosote has accumulated (1/4" or more), it
should be removed to reduce the risk of chimney fire. Running
the furnace at maximum with the bypass pulled out for 1 to 2
hours about once a week will minimize creosote buildup.
OPERATION INSTRUCTIONS
The following operating instructions must be followed
carefully for satisfactory operation.
FUEL
In the event of an uncontrolled chimney fire, shut the
bypass damper and turn down the thermostat.
If the chimney fire does not die down, keep watch on the fire
and prepare to vacate the house. If needed, call the fire
department.
NOTE: Establish a routine for the storage of fuel, care of the
furnace and firing technique. Be aware that during mild
weather and low furnace temperatures, more creosote is
deposited and more frequent cleaning is necessary.
HINT: To avoid creosote build-up especially in mild
weather, fill the furnace only part way. Also, well seasoned,
unchopped wood will reduce creosote build-up dramatically.

Fuel wood can be of any species. However, ensure that
the wood is well seasoned and kept under cover. Do not burn
any fuel other than wood. Please note that if you use green
wood:
• The amount of wood that you use will increase around
20% when using green compared to dry wood.
• Heat output will be considerably lower and more frequent
fuelling will be necessary.
• Green wood must be cut into smaller pieces to burn
acceptably.
• Creosote formation may increase, especially in warm
weather.
• The fire will most likely have to be started with dry wood
until a good bed of coals is formed.

When the bypass damper is open (i.e. the bypass rod is
pulled out) combustion will take place within the entire firebox.
Operate the furnace with the bypass damper open only when
you need quick heat.
• When the desired temperature has been reached, push
the bypass rod in.
• Whenever there is a fire burning, the bypass damper
should be open for 30 seconds before you slowly open the
door.
• When you are starting a fire, the bypass damper should
be open to vent away smoke.
• The furnace door must be closed at all times, except
when you are loading fuel or checking the fire.
LIGHTING
Light a fire in the furnace, starting with paper and kindling
only. Never use any flammable liquids. After the fire is lit,
leave the door open a crack for a few minutes. Once a coal bed
is established, add standard cord wood and latch the door
shut.
THE FIRST FIRE
You will experience a slow start-up during the first fire.
The firebricks bricks still contain moisture and take a good hot
fire to eliminate the moisture. While there is moisture in the
bricks, the bricks will be black with smoke deposits. When the
moisture is gone, the bricks will be light coloured. You may
also experience a slight odour during the first few fires. This
odour results from the curing paint and the burn-off of residual
oils.

WALLTHERMOSTAT OPERATION
FURNACE MAINTENANCE
Set the thermostat to the temperature desired. When the
furnace is warming up a cold room, there will be an initial
temperature overrun, then the temperature will stabilize.
DAILY
REFUELLING
1. Have wood on hand to load the firebox.
2. Open the bypass damper for 30 seconds
3. Open the door slowly. Allow the chimney to draw off
smoke.
4. Load as much wood as you need (right up to the top in
cold weather).
5. Close the door and push in the bypass damper.
NOTE: Do not over- fire the furnace by leaving the door
open. The door should be open only when you light and
check the fire. Operation with the door ajar voids the
warranty.
OPERATION IF THE POWER FAILS
(NOT FOR USE IN FURNACES WITH DOWN FLOW
DUCTING)
1. Open the panel opposite to the air inlet to the wood
section to allow for air circulation.
2. Open all floor registers.
3. Adjust the draft manually by pulling up the chain just
below the damper motor lever, and placing it into the small
damper motor lever
For the first little while, check the chimney and pipe until
experience shows how often cleaning is necessary. About
once a week, run the furnace at maximum with the bypass open
for one to two hours to burn off any creosote in the chimney
and pipes. This should greatly reduce how often you will
need to clean the chimney with a brush.
AS NEEDED
Any creosote build-up in the chimney and pipe over 6 mm
(1/4") should be removed with a brush. Make sure that the
bypass is open before you begin cleaning the chimney.
ASH REMOVAL
Ashes should be removed once they reach a depth of 100
mm (4") maximum. Let the fire burn out. Protect the area in
front of the furnace with a non- combustible material. Shovel
the ashes into a metal container with a tight fitting lid. Other
waste should not be put in this container.
The closed container of ashes should be placed outside
on a non-combustible surface, or on the ground, well away
from any combustible materials. If the ashes are disposed of
by burial or otherwise locally dispersed, they should be
retained in the closed container until you are sure that all of
the cinders have thoroughly cooled.

Figure 2: Operation during a power failure
slot beside the chain guide (see Figure 2)
Do not expect as much heat in cold weather, because duct
work is not designed for heating without a blower. When
power is restored, the damper motor will automatically pull the
chain off the slot and resume normal operation.
• To adjust the door up or
down, loosen the bottom two
nuts, adjust the door. Tighten
the nuts.
NOTE: The chain guide must be "clipped" by installers if
the furnace is installed to heat areas below the furnace.

Furnace Installation
IFYOU HAVE AN OILADD-ON
Operate the oil fired unit periodically to ensure that it will
operate satisfactorily when you would like to use it.
DOOR
The door is a unique adjustable centre-push design to
ensure trouble-free, air tight operation for years to come.
When you close the door, there should be a slight resistance.
If there is not, the door needs adjusting. The door pawl (the
catch on the closing mechanism) should be lubricated regularly with a high temperature grease, so the door opens and
closes easily.
If the fibreglass seal shows signs of excessive wear, it may
not seal properly, and cause the furnace to burn hotter than
desired. Replace it with a gasket replacement kit (part #
FDGRK5)
DRAFT CONTROL
Check that the draft control opens and closes freely. If it
does not, open the front left panel and make sure the chain is
not binding.
FIREBRICK
Take care when you are refuelling the furnace to avoid
breaking the brick. If you are burning wood with chunks of ice
and/or snow, do not let the frozen surfaces touch the firebrick.
If any firebrick breaks, replace it immediately in order to avoid
overheating the firebox.
FURNACE INSTALLATION
The F75R and F101 furnaces may be installed as follows:
1. As a stand-alone wood furnace with blower.
2. As an add-on to a stand-alone oil, gas or electric
furnace.
WARNING: These furnaces are not certified for use with an
automatic stoker.
CHIMNEY CONNECTION
The furnace must be installed with a minimum of elbows
and horizontal flue pipe. All horizontal pipe must slope
towards the furnace and be installed with the seam up. The
flue opening on top of the furnace is designed so the pipe will
fit inside the opening. Make all connections in such a way
that any condensation in the flue runs back into the furnace
and not on to the floor. After installing the pipe, each joint
must be secured with 3 screws spaced evenly around the joint.
All single wall stove pipe must have a 460 mm (18") clearance
from all unprotected combustible material.
CAUTION: Under no circumstance is any type of damper or
restriction to be installed in the connection between the
furnace and the chimney. A barometric draft control must be
installed and set at 15 PA (0.06") draft. Removal or noninstallation of the barometric damper voids the warranty.

NOTE: (In U.S.A. only) You may not connect this furnace to
a chimney flue serving another appliance.
ARDENT Energy furnaces burn very efficiently, resulting
in lower than usual flue gas temperatures. Consequently, we
do not recommend an outside installation of the chimney. If
you have an exterior chimney, certain weather conditions will
cool the chimney below room temperature. When this happens, a back draft and/or creosote formation will occur.
If you are using an existing chimney, it must be inspected
carefully for soundness and to be sure that the preceding
requirements are met.
Note: Optimum performance for these furnaces are obtained
with a draft of between 0.06" and 0.07" (Water Column).
After the installation is complete, the draft must be checked
by your dealer, using a draft gauge while the furnace is
operating at a normal temperature.
CHIMNEYTERMINATION
Chimneys are required to extend at least 915 mm (3 ft.)
above the highest point where they pass through the roof of
the building and at least 610 mm (2 ft.) higher than any portion
within 10 feet.
In some cases, the chimney must be higher than the
minimum for proper draft, due to unfavourable geometry of
surroundings.

FLOOR PROTECTION
If the floor is combustible, it must be protected by 7 mm
(9/32") or thicker of noncombustible material extending 150 mm
(6") from the sides and rear, and 460 mm (18") from the front.

ASSEMBLY
After deciding which side is best for the blower unit,
remove the inlet cover on that side. Use the screws to attach
the connector. The blower sits on top of the connector,
oriented so that the air moves down into the wood furnace
when the blower is on. Make sure that the fan pulley is 203
mm (8") in diameter.

• Control kit model FEFC3, which includes:
• Thermostat
• Damper motor
• 2 fan/limit controls mounted on a bracket
• Wiring harness with LV terminal block
Prepare the plenums and connecting ducts:
• The connecting duct between the oil furnace and the
wood furnace must be 305 mm x 460 mm (12" x 18") with
elbows having a minimum inside radius of 150 mm (6").
Your electric furnace blower must be large enough to keep
the furnace equal to or below the following maximum temperature rises:
• Do not connect duct work so that reverse flow is
possible (the cold air return must not be higher than the
warm air outlets).
• After the installation is complete, recheck the air flow as
before. If the air flow is less than before, the blower speed
must be increased to compensate for the pressure drop
through the system.
• For multi-speed blower motors, use the higher speed, if
needed.
• For belt-driven blowers, adjust the pulley diameter on the
motor to give the extra speed required. If necessary, a
larger blower motor may be used if the faster speed
increases the air flow above the rating on the motor
nameplate. HOWEVER, THE BLOWER MUST NOT BE
CHANGED.

WATER HEATING COIL
ARDENT Energy furnaces are designed to heat your
domestic hot water during the heating season. The F75R and
F101 can accept 1 or two coils (1 per side). When you install
the water coil (part FCSHW4) it replaces all but one of the
firebricks on the side it is located. Please read all of the
instructions before you begin.
To install the water coil:
1. Remove the back shroud on the furnace by removing
the screws. Using a good punch and hammer, punch out
the two knockouts on the side where you would like to
install the water coil.
2. Remove all of the firebrick from that side.
3. Punch out the two knockouts at the rear of the firebox.
4. Remove the baffle plate inside the rear of the firebox.
5. Position the water coil in the firebox, in the place where
the firebrick was removed. The pipe must face the fire.
6. Install the ceramic gaskets and plates on the outside of
the firebox (not on the outside of the shroud) using the
provided drill and tap screws.
7. Replace the shroud.
1. Let the furnace cool down.
2. Close the valves between the range boiler and the coil.
3. Open the drain valves and drain the water from the coil.
4. Disconnect the coil at the unions.
5. Clean the coil using a drain cleaning "snake."
6. Connect the piping, close the drain and open the valves
to the boiler.
WHEN YOU HAVE NO WATER
Do not operate your furnace with a dry water coil. The
excess heat will damage the water coil. If you have no water
insulate this

CONNECTING THE COILTO THE TANK

(uninsulated)
to drain
We recommend that you use the "two tank" system. The
first tank or "range boiler" must remain uninsulated to dissipate any excess heat generated by the hot water coil.

Furnace Options
for circulation, disconnect and remove the coil. To seal the
holes, use two 25 mm (1") diameter standard washers per hole,
and use a 19 mm x 25 mm (3/4" x 1") bolt to hold the washers
together.
PAINT
You may touch up the face of the furnace with STOVE
BRIGHT Satin Black 1990 high temperature paint. The correct
paint is available from your dealer. When you paint the face of
the furnace, cover the area surrounding the furnace with
newspaper. Follow the directions outlined on the spray can.
DO NOT attempt to paint while the furnace is still warm. Keep
the spray can away from any source of heat or open flame.
Ensure that there is adequate ventilation in the room, from the
time you start painting until the paint is dry.
