Location
Refer to C.S.A. B139 “CODE FOR INSTALLATION OF
OIL BURNER EQUIPMENT” for recommended installation
practices. Consider the following before placing the furnace;
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.
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.
.03 to .05 inches WC at the flue connection of the furnace, 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 fire to burn out of control. Minimum inside chimney 64 sq. inches.
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 pivoting axis has to be horizontal. Follow instructions for
installation which is supplied with the Draft Regulator.
Thermostats:
How To Install Fire Brick: Drawing #2
Select a location which is representative of the average
house temperature, usually the living room. The thermostats 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.
1. Install 6 brick in floor of firebox (see layout)
2. Place bottom row of bricks (for fire box sides, front
and back), making sure bricks are in brick plate
support frame which is an integral part of the box.
3. Repeat second and third rows of brick.
4. Install stainless steel front brick guard using bolts
provided.
5. Install “U” shaped top brick guard, inserting open ends
of guard into loops provided on inside of door opening.
For masonary chimneys refer to C.S.A. B1398 (p. 83). For
All Fuel chimneys consult manufacturers’ tables.
Furnace Assembly: Drawing #4
Locate Heat Exchanger Section in desired area
Four location points for locating blower port are supplied
on left and right side of furnace section, burner end.
Cut desired side for blower to enter furnace section.
Place blower section against furnace section and attach

the controls included in these instructions.
All electrical equipment and wiring has to installed following 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 perfect 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.

Model SBB
higher than room temperature. This will open the draft
damper allowing combustion air into the furnace.
Important: These Entire Instructions Must Be Read
Light the paper and close the fire charging door.
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.
When the kindling is burning well put in some hardwood
and allow this to begin burning.
Owner’s Operating Instructions
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 installation clearances.
Build a small intense fire at least once a day to reduce
creosote build up.
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.
For safety keep fire charging door tightly closed.
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.
Do not adjust electrical control settings or blower pulley
arrangement.
It is better to build small intense fires than building large
smoldering fires as they reduce creosote build-up.
Operate the oil-side of unit once a week to ensure that it
will operate satisfactorily when needed.
Ash Removal
Clean chimney at least once a year, and inspect regularly
for creosote build up.
1. Allow fire to burn out.
Keep fire door closed and maintain all seals in good condition.
Make sure adequate combustion air is provided in furnace area.
DO NOT START WOOD FIRE IF OIL VAPOUR IS PRESENT.
Firing
Start the fire in your furnace with paper and kindling only.
Crumple a quantity of paper and place it on the “Floor”
of 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
2. Turn “Wood” thermostat to its lowest setting. This deactivates damper motor and allows damper door to
close (or de-activates combustion air fan if so
equipped).
3. Remove ash with clean-out tool provided.
4. Ash is to be disposed of in a steel container with a
tightly fitting lid and take out of doors immediately.
Other waste should not be placed in this container.
5. After ash removal return “Wood” thermostat to normal
setting and restart fire.
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 creosote is deposited, and weekly cleanings may be necessary in mild weather even though monthly cleanings may
be enough in the coldest months.
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
door open.
Load solid fuel carefully as damage will result from careless operation.
Green wood burns poorly and produces less heat, more
smoke and creosote.
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.
For best results burn dry wood or hard coal. Do not burn
salt saturated driftwood, tar products, tires or trash.
Fuel Storage:
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 allow any wood fire to smolder and cool the flue
system as this type of operation condenses the flue gas
products creating creosote.
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 frequent 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.
Do not store coal or combustible material within minimum 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 creosote.
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.
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 operates.
Starting the oil burner:
How To Use Solid Fuel Side
Burn wood only - For maximum efficency burn well seasoned hard wood only.
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.
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 maximum comfort.
What to do when your oil furnace fails to start
Caution:
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 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:
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 thermometer 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.
Honeywell - L4064J,11” insertion, limit setting 210°F,
positive stop.
White Rodgers - 5D51- 78, 11” insertion, limit setting
205°F, positive stop.
Warning - If the limit control is defective the furnace is
unsafe to operate.
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.
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.

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 products, 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 resulting 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 preventing 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.
