Installation of the combination furnace
Location
Refer to C.S.A. B139 “CODE FOR INSTALLATION OF OIL
BURNER EQUIPMENT” for recommended installation
practices. Consider the following before placing the fur-
nace;
The furnace should be centrally located in relation to the
outlet registers, with large warm air ducts, for improved
heat distribution during electrical power failures, when
the furnace has to work on the gravity principle.
The flue connection to the chimney should be short and
direct and consist of as few elbows as possible.
Sufficient space must be provided for access to the
burner, the controls, and along one side and at the rear
of the unit to provide access to the filters and blower.
See above for required clearances.
To ensure an easy installation of the two part furnace,
prepare a cement pad size 50” X 45” at least 2” thick, as
level as possible. It makes alignment of the two parts
easier.
In all cases, local building codes should be observed.
Duct Connection
The return air duct connection should be tight, so that
the blower cannot draw air from he furnace room which
can interfere with the combustion air supply. A plenum
chamber or an elbow type connection may be used.
Sufficient air flow must be provided for efficient opera-
tion. An opening into the furnace room should be made
to the outdoors if there is not sufficient air infiltration. The
equipment has to be installed in accordance with the
standards of the National Board of Fire Fire Underwriters.
Authorities who have jurisdiction should be consulted
before installations are made.
MBFU Standards Include:
Standards for the installation of oil burning equipment.
NBFU No. 31.
Standards for the installation of air conditioning, warm
air heating and ventilating system. NBFU No. 90.
Building code standards for the installation of heat-
producing appliances, heating, ventilating, air condi-
tioning, blower and exhaust systems.
Chimney and Flue Pipe
The chimney should be thoroughly inspected and
cleaned to ensure safe furnace operation.
It is very important that the chimney has an adequate
capacity and develops a good draft for proper combustion.

Installation of the Combination Furnace
(continued)
Chimney and Flue Pipe
.03 to .05 inches WC at the flue connection of the fur-
nace, and .01 to .03 inches draft over the fire. Maximum
chimney draft should never exceed - 0.03” WC since a
power failure could cause wood or coal fire to burn out
of control.
The flue pipe must be full size and not lighter than No. 24
gauge black iron pipe. The flue pipe connection should
be short and direct with as few elbows as possible and
should slope up toward chimney. Make certain the flue
pipe or thimble does not project into the chimney flue. All
sections of the flue pipe should be fastened with sheet
metal screws. Under no circumstances should the flue
pipe contain a hand-operated damper.
Warning: Do not mount flue pipe close to or in front of
limit and operating controls.
Draft Regulator:
The draft regulator may be located on either the vertical
or horizontal section of the flue pipe. The best location is
18” from the furnace flue outlet. The regulator must be
level (without leaning forward or backward) and the pivot-
ing axis has to be horizontal. Follow instructions for
installation which is supplied with the Draft Regulator.
Thermostats:
Select a location which is representative of the average
house temperature, usually the living room. The thermo-
stats should be mounted on an inside wall, never where
they will be subjected to drafts (warm or cold), above a
radio or television set, or where the sun’s rays or heat
from registers will affect them. See instructions supplied
with the thermostats.
For masonary chimneys consult manufacturers’ tables.
Furnace Assembly:
Set down the heat exchanger. Before assembling the
blower section, assemble motor, adjust the leg for belt
tension. Install blower and motor pulley. Assemble the
motor to the blower section on the motor mounts which
are already in place. Line up pulleys with straight edge by
sliding motor along the track and fix position with bolts.
Install belt - tighten it by adjusting the leg, leaving belt
movement to a maximum of one inch under finger pres-
sure. Install motor wiring harness using push on connec-
tions. NOTE: Green centre wire goes to the ground, two
outside wires on motor leads are interchangeable.
Remove lower spacer panel screws from furnace section.
Assemble the blower section by tilting it, so the flames fit
into the heat exchanger section. Screw both sections
together.
How To Mount The Burner:
The burner is flush mounted with three positioning bolts
on the front plate. Connect the burner conduit cable pro-
vided on the wiring harness - follow wiring diagram.
Check nozzle size, tightness and chamber alignment.
Set up burner to #1 Smoke.
Wiring The Furnace: Drawing #3
Each furnace is supplied with the necessary wiring har-
ness. Follow diagrams for wiring and correct location of
the controls included in these instructions.
All electrical equipment and wiring has to installed follow-
ing the requirements of the Canadian or U.S. electrical
code as well as regulations of local authorities.
Solid Fuel Damper Control: Drawing #1
The thermostat for the solid fuel section activates the
damper control - which in turn moves the damper flap. It
is essential that the damper control is at all time in per-
fect working order.
Note: Adjust damper chain so that damper flap opens no
more than 1/2”.
When oil is used as fuel close all combustion air inlets to
solid fuel side of furnace. Excessive air decreases the oil
burner efficiency.
How To Install Fire Brick: Drawing #2
1. Place bottom row of bricks in fire box. Make sure
bricks are in brick plate support frame which is an
integral part of the box.
2. Repeat second and third rows of brick.
3. Install stainless steel front brick guard using bolts
provided.
4. Install fourth row of brick, sides and back.
5. Install “U” shaped top brick guard, inserting open ends
of guard into loops provided on inside of door opening.
Note: *Due to the taper design of firebox mortar is not
required.
* Grates are shipped installed in furnace.

Owner’s Operating Instructions
Important: These Entire Instructions Must Be
Read
These entire instructions must be read to ensure the best
possible operation and safest use of the furnace.
Manufacturer’s recommendations and codes set down
by regulating authorities must be followed when installing
and operating furnace. ALL solid fuel burning furnaces
manufactured by Trent Metals Limited have been tested
for safety by the Canadian Standards Association
Laboratories and carry their Certificate of approval which
is recognized by Insurance Underwriters in Canada.
Cautions
Do not use chemicals or fluids to start the fire.
Never fire with treated wood, or burn garbage, gasoline,
naptha or engine oil.
Never load wood in firebox higher than height of door sill.
Do not store combustibles within the minimum installa-
tion clearances.
Build a small intense fire at least once a day to reduce
creosote build up.
Clean chimney at least once a year, and inspect regularly
for creosote build up.
For safety keep fire charging door tightly closed.
Do not adjust electrical control settings or blower pulley
arrangement.
Operate the oil-side of unit once a week to ensure that it
will operate satisfactorily when needed.
Keep fire door closed and maintain all seals in good con-
dition.
Make sure adequate combustion air is provided in fur-
nace area.
Firing (See separate “Coal Firing Instruction” in this
manual)
Star the fire in your furnace with paper and kindling only.
Crumple a quantity of paper and place it on the grates in
the fire box.
Randomly stack kindling on top of the paper allowing for
good combustion and air circulation.
Set your thermostat so that it is 7-10 degrees fahrenheit
higher than room temperature. This will open the draft
damper allowing combustion air into the furnace.
Light the paper and close the fire charging door.
When the kindling is burning well put in some hardwood
and allow this to begin burning.
Add hardwood;
do not fill the firebox above the door sill
do not put in too much wood at one time during
initial start-up as you could smother the fire.
When fire has been established properly, set thermostat
to your desired setting. The thermostat controlling the
wood section should be set at 5° above the oil section
thermostat i.e. set oil section thermostat at 18° C (65°F)
and the wood section thermostat at 21°C (70°F).
Maintaining Fire
You will be required to maintain the fire in you home
manually.
The rate at which you have to charge your furnace will
vary with the size of house, type of wood and weather
conditions.
When the fire in your furnace is not great enough to
properly heat your home the air circulation blower fan
will begin to come on more frequently. In a few days you
will establish the basic recharging period for your specific
application.
It is better to build small intense fires than building large
smoldering fires as they reduce creosote build-up.
Ash Removal
Keep your ash pit clean, never let ashes build up to the
underside of grates. This will prevent overheating of ash-
pit and grate bars.
Move “Solid Fuel Thermostat” to a low setting - to allow
damper Flap to close.
Using short “choppy strokes” shake ash in fire bed allow-
ing it to fall through into ash pan.
Using gloves or some type of protection from the live
“coals” that may be in the ash pan, remove the ash pan
and dispose of ashes in a steel container with a tightly
fitting lid and take out of doors immediately. Other waste
should not be put in this container.
Replace ash pan, close clean out door and move solid
fuel thermostat to normal operating setting.

Furnace Maintenance and Care
Establish a routine for the storage of fuel, care of the
appliance, and firing techniques. Check daily for creosote
build up until experience shows how often cleaning is
necessary. Be aware that the hotter the fire, the less cre-
osote is deposited, and weekly cleanings may be neces-
sary in mild weather even though monthly cleanings may
be enough in the coldest months.
Have a clearly understood plan to handle a chimney fire.
To control creosote when burning wood in temperate
weather, stoke often with a small intense fire. Heat
requirements should determine the size of the wood fire.
To help control creosote build up in furnace, burn well
seasoned hard wood, sun dried in an open area for at
least 12 months.
DO NOT CLEAN OIL SIDE COMBUSTION CHAMBER.
Do not allow any wood fire to smolder and cool the flue
system as this type of operation condenses the flue gas
products creating creosote.
Keep your ashpit clean. Never let ashes build up to the
grate bed. This will prevent overheating of ashpit and
grate bars.
When burning solid fuels, load your fire box up to the
height of the doorsill. Do not overfill.
Combustion air is supplied over the fire bed by air holes
in the fire door to help retard creosote formation in the
flue systems. Operate oil side one day per week to help
reduce creosote formation.
Clean filters at least once a month and replace with new
filters twice a year, unless conditions require more fre-
quent replacement. If air flow is obstructed, the furnace
will run longer and waste fuel.
Oil blower motor as well as oil burner motor where oil
cups are provided at least twice a year with number 20
auto oil, 4 or 5 drops for each cup. Do not oil blower
bearings.
Contact your installer on any service problems or
replacement parts.
How To Use Solid Fuel Side
Burn wood and coal only. Do not use with automatic
stoker.
Remove ashes daily as ash build-up will result in prema-
ture grate bar and ashpit failure, voiding warranty.
DO NOT LOAD SOLID FUEL ABOVE FIREDOOR SILL
HEIGHT AS OVERHEATING WILL RESULT CAUSING
PREMATURE FURNACE FAILURE, A FIRE HAZARD AND
VOID WARRANTY.
Adjustment of the solid fuel air damper should never
exceed 1/2 inch open. A fixed limiter is installed on your
furnace to insure this maximum opening, and is not to be
tampered with.
Do not use chemical or liquids to start fire.
To charge or inspect solid fuel side with scrap wood,
push up smoke baffle and secure with smoke baffle tool,
over door in full open position. Do not operate with fire or
ashpit doors open.
Coal Burning:
Allow flames to burn through fresh coal charge before
closing air damper for low firing conditions. (eg. before
banking the fire overnight).
Load solid fuel carefully as damage will result from care-
less operation.
Green wood burns poorly and produces less heat, more
smoke and creosote.
For best results burn dry wood or hard coal. Do not burn
salt saturated driftwood, tar products, tires or trash.
Fuel Storage:
Do not store coal or combustible material within mini-
mum clearances.
See minimum installation clearances to combustibles
label.
Store wood at least 8 feet, or twice the height of the pile
from the furnace.
To control creosote when burning wood in temperate
weather, stoke often with a small intense wood fire.
Do not load to capacity allowing the fire to smolder. A
low temperature, smoldering wood fire generates cre-
osote.
The chimney must be capable of a - 0.05 in. W.C. draft at
all times. The safe operating range is from - 0.03 to -
0.05 W.C.
Note: For wood burning, shake grates only enough to
maintain combustion air through the fire bed.

How To Use Oil Side:
There are two thermostats, one to control the solid fuel
section and one to control the oil operating section. Set
solid fuel thermostat at its lowest setting to prevent solid
fuel damper control form cycling when oil burner oper-
ates.
Starting the oil burner:
The operation of the oil burner is entirely automatic. To
start it, set room thermostat above room temperature.
Open shut-off valve at the oil storage tank, set burner
line switch to “on” position, bleed air with the bleeder
plug on the pump. Check the pump diagram attached to
the burner. As soon as pure oil (not foam) flows, shut
burner down and tighten plug. The burner will start and
operate automatically.
During extreme winter conditions, the oil burner can be
safely fired to supplement the solid fuel side for maxi-
mum comfort.
Maintenance
Ashes never should be allowed to accumulate in the ash
pit so they in any way impede the flow of combustion air
to the fire. Excess ash accumulation can cause the fire to
go out, and also can cause severe damage to the grates
because they cannot cool from a flow of air beneath
them. Ashes MUST be removed daily and put in a metal
container with a lid.
Clinkers can occur in any coal furnace. They are pieces
of fused ash that are hard. They can become large, and
therefore cannot be shaken through the grates in a coal
furnace. When there is an appreciable accumulation, the
fire will go out because insufficient air is allowed to pass
through the clinkers to the burning coal. Once clinkers
have formed, they can be removed only from above the
grates. This usually means the fire must be allowed to die
out before they can be removed.
Clinker formation can occur from a number of different
causes or a combination of causes. Some of these are as
follows:
Too hot a fire (too much draft);
Too shallow a bed of coals;
Too deep a bed of coals;
Excess shaking;
Poking the fire from the top;
Poor quality coal - excess ash content;
Too little air (draft) after a long hot fire.
Safety
Whenever a loading door is opened, it always should be
cracked slightly before full opening to allow oxygen to
enter and burn any combustible gases that are present.
Failure to do this could result in sudden ignition of the
unburned gases when the door is opened.
A furnace never should be filled with excess coal so that
the flue gas exit is in any way blocked or impeded.
Burning coal generates carbon monoxide. If the flue gas
exit is blocked the carbon monoxide can be forced out of
the furnace that does not have an airtight, unified chim-
ney system. The furnace should be used only with chim-
ney systems that provide a strong, reliable draft. With the
exception of the start-up period, an ash pit door NEVER
should be left open.
Do not use an automatic stoker with this furnace.
Note: After a coal fire goes out, all the coal must be
emptied from the furnace and the complete starting
process must be repeated. The coal burning learning
process is often long and frustrating, but once the proper
procedure is established and followed, coal burning
becomes a reasonably simple process, with the benefits
of long burn times and evenness of output over the entire
length of burn.

Coal Burning Instructions
The flue draft must be -.05” W.C. to allow combustion
gases to flow freely out the chimney. Turn the solid fuel
thermostat up to a setting well above the room tempera-
ture to open draft flap. Use paper and dry kindling to
start the fire.
Add small compact pieces of hardwood when the kin-
dling is burning hot. The ash door may be opened for
start-up. However, close the ash door before opening the
fire door to prevent smoke from emitting out the fire door
opening.
When a substantial bed of red coals is built up, start
adding coal, small amounts at a time. Continue adding
small amounts of coal until there is a solid bed of burning
coal. Do not add too much at one time. Allow sufficient
time between each small loading (at least 10 to 15 min-
utes) so that each loading has time to thoroughly ignite
before the next load is put in. For maximum burning effi-
ciency, always fill the furnace to the highest level possi-
ble. A deep bed of coal always will burn more satisfacto-
rily than a shallow bed.
Now turn the thermostat to the desired room temperature
setting. If the ash door has been opened, close it to pre-
vent overfiring, which can severely damage the furnace.
Loading
Coal should be added to the fire at least every twelve
hours. Coal never should be added unless there is a rea-
sonably hot fire.
If the fire is burning hot and there is a deep bed of coals,
full loads of coal can be added at any time. However, if
there is not a deep bed of coals, it is best to add small
amounts of coal at first.
Shaking
Shaking should be done only with a hot fire.
Shaking should be done a least once a day, but not more
than twice a day.
Best results from shaking will occur if short “choppy”
strokes are used rather than long even strokes.
The amount of shaking is critical. Too little or too much
can extinguish a fire due to blocked air flow. The proper
amount normally occurs when red coals first start to drop
through onto the bed of ashes. Be sure that a small
amount of ash is left on the grates to protect them from
direct heat of the burning coal.
Eastern Soft Coal:
Due to the “coking” tendencies of Eastern Canadian Soft
Coal, these coal burning instructions must be followed
exactly; and coal must not be built up above the door sill;
ash deposits must be kept off grates and the ash in the
ash pan must be allowed to build up under the grates.
Failure to adhere to these instructions will void warranty.
What to do when your oil furnace fails to start
1. Raise your thermostat to 5°C (10°F) above the present
room temperature.
2. Make sure your burner switch is in “on” position.
3. Check the fuse box for blown fuses. Replace with
fuses of correct amperage.
4. Press the reset button on relay box, once only. Box is
located on burner.
5. If you hear a hum from the burner, and the motor has
not started, press the button on the oil burner motor.
If oil burner fails to start or runs only for a few seconds,
call a reputable serviceman.
Caution:
Never start oil burner under the following conditions:
1. If excess oil has accumulated in the combustion
chamber.
2. If furnace is full of vapour
3. If combustion chamber is very hot.
4. Do not throw lighted paper into combustion chamber
when motor is running but oil is not burning.
Procedure for checking the proper function of
the limit safety control
This procedure is CSA requirement and must be carried
out by service man:
1. Once each heating season.
2. After an extreme wood fire.
3. After the unit has been used in gravity conditions
(without electrical power).
The objective of this procedure is to temporarily over
heat the furnace to prove the limit control is operational.
a) Fire the furnace with oil. Wait until the circulating air
blower is running. Move drapes or furniture that may
be damages by heat away from the warm air registers.
b) Adjust the oil thermostat to its highest setting in order
to keep the burner operating.

c) Insert a duct thermometer to its highest warm air duct
at a point 12 inches downstream from the furnace
plenum. If the limit control is functioning correctly the
burner will shut off on high limit before the thermome-
ter reads 200°F.
d) To begin the test, close all the warm air registers then
block the cold air returns with newspapers.
e) Watch the oil burner and note the temperature of the
warm air when the burner shuts down.
CAUTION:
If the warm air temperature exceeds 200°F without the oil
burner shutting down quickly open the warm air registers
and remove the blockage from the cold air return.
If test procedure did not end with the oil burner cutting
off, the limit control is defective.
If the limit control is defective immediately replace it with
one of the following:
Honeywell - L4064J-5” insertion, limit setting 205°F
positive stop.
Warning - If the limit control is defective the furnace is
unsafe to operate.
Emergency Procedure
Soot or Chimney Fire
1. Close damper door by unhooking chain.
2. Close fire door.
3. Do not remove flue pipe before fire is completely out.
4. Call the fire department.
Run-A-Way Fire
1. Close damper door by unlocking chain.
2. Close fire door.
3. Close off all air from entering the firebox.
4. Fully open barometric damper to reduce draft.
5. Douse the fire with water to reduce the rate of com-
bustion, if necessary.
Power Failure
1. Close damper door by unhooking chain.
2. Close fire door.
3. Remove access door at each end of furnace blower
compartment.
4. Open all air registers fully and furnace room door to
give better circulation.
5. Do not load fire box higher than 1/4 way up during
gravity firing.
6. The combustion air can now be supplied by opening
the secondary air control.
7. Open all warm air registers full open. Registers must
not be obstructed by furniture or drapes.
8. Continue to operate a small fire for duration of power
off period. Do not expect to maintain maximum com-
fort under no power conditions. To prevent injury do
not allow anyone who is unfamiliar with the operation
of the furnace attend it.
9. On return to normal power operation, return all altered
items to their normal operating positions.
For more information read labels and manual carefully.
NOTE: THE EXCESSIVE HEAT CAUSED BY AN
EXTREME FIRE MAY DAMAGE THE FURNACE SAFETY
CONTROLS. THEIR OPERATION SHOULD BE CHECKED
BEFORE THE FURNACE IS RETURNED TO SERVICE.

TION OF THE LIMIT SAFETY CONTROL.

Creosote - Important Woodburning Information
Creosote is the tar-like substance that forms on the heat
exchanger, flue pipe and chimney when burning wood.
Wood combustion is never complete, a visible sign is
smoke coming from your chimney.
Wood when freshly cut can contain as much as 50%
moisture, depending on the type. Air dried wood, when
under ideal conditions, will still contain approximately
20% moisture. The moisture, along with flue gas prod-
ucts, are vented outside by way of the flue pipe and
chimney. Flue gas products, when chilled, condense into
liquid creosote which may become a crystal (solid form)
as temperatures increase with heat requirements.
The heat control method on furnaces when burning
wood, is the size of the fuel charge along with the control
of combustion air, to increase or decrease the rate of
burning which governs the heat output.
To help prevent creosote in both grate and base burners,
burn dry seasoned wood, hard wood is more desirable
than soft wood. Govern your wood load with the heat
output required. Spring and fall require frequent small
charges. A small intense fire produces less creosote.
Short flue pipe runs help to keep the gases above the
dew point.
The interior chimney holds and retains heat longer result-
ing in less condensation than the exterior chimney.
A good draft produces a hotter fire and exhausts the flue
gases outside more rapidly at higher temperatures pre-
venting condensation of flue products.
A combination furnace in need of cleaning, will have poor
draft creating a lazy fire and eventually, if ignored, may
smoke around the doors when the oil side is running with
wood fire. (Poor draft in a clean system can also produce
smoking around the door). This choked condition with
soot and creosote can only be relieved by cleaning the
entire system as frequent as necessary, if neglected it will
cause a chimney fire, which could result in property loss
and danger to lives of occupants.
Wood burning equipment must be vented into a factory
built OR masonary chimney. Chimneys must be built to
Building and Energy Board standards. Do not neglect
cleaning, or deliberately set your chimney on fire to burn
out the soot and creosote. If no damage is done to the
house, there will be damage to the chimney caused by
extreme heat. Not even the best chimneys are designed
for withstand repeated chimney fires.
