SECTION A : wood or wood electric furnaces

INTRODUCTION.

To get maximum performance from your PSG furnace, keep in mind the following:

• Comply with local codes (if in doubt, contact your local heating specialist).

• Make sure your furnace is installed according to the instructions on the certification plate.

• Make sure that your furnace has been installed in accordance with the required standards specified on the

furnace’s certification labels.

1. CHIMNEY AND DRAFT

This furnace must be connected to a chimney approved for wood-burning appliances; the chimney connector for a
PSG 2000 must have 6" diameter; 7” for PSG3000 and PSG4000, for all other models, use an 8" diameter chimney
connector.

Use of a barometric draft control is recommended in order to regulate the draft to the recommended setting.
Never use a manual chimney damper.

The barometric control must be adjusted so that the maximum draft measured at the furnace outlet does not exceed

-0.06 in. w.c. Please note that a draft exceeding -0.06 in. w.c. could produce an uncontrollable fire. On the other
hand, the minimum draft required is -0.04 in. w.c. in the evacuation pipe on the wood side, no matter what type of
furnace (PSG Wood, PSG Wood/Electric and PSG Wood/Oil).

2. SAFETY RULES

GENERAL REQUIREMENTS

• Never light your furnace using chemicals or other liquid fuels. Never installed automatic feeder on that unit.

• Do not burn wood coated with paint, glue or chemical products.

• Never store wood near the furnace. Respect the required minimum clearances between combustibles and

your furnace.

• Keep your furnace, chimney and smoke pipe connector clean and in good working order at all times. We
recommend that you establish clear procedures for wood storage, system maintenance and operation of
your furnace. Check creosote accumulation daily until you can determine by experience how often to clean.
Weekly cleanings may be necessary in mild weather, while a monthly cleaning may be all that is required
during the colder months of the year.

• Keep loading and ash drawer doors shut during operation and make sure their gaskets are in good
condition. To get a replacement gasket, contact your PSG dealer.

• A plentiful supply of combustion air and a vigorous fire will help prevent creosote accumulation.

All controls adjustments must be performed by a qualified technician. The controls settings and the blower speed must
conform to the recommendations of the National Warm Air Heating and Air Conditioning Association and respect the
recommended static pressure ranges in the warm air bonnet of the furnace (see General Technical data static
pressure).

W A R N I N G

THE ASH DRAWER GET VERY HOT.

DO NOT MANIPULATE WITH BARE HANDS.

ODOUR FROM THE PAINT

It is normal that a smoke odour emanate from the unit when you first light it. It is recommended to burn it at high

rate and ventilate the building until the odour resorbs.

ASH DISPOSAL

Ashes must be placed in a metal container with a tight fitting lid. The container should be placed outside, well away
from combustible materials. If the ashes are meant to be buried in soil, you should wait until all cinders have
thoroughly cooled.

CREOSOTE BUILD-UP AND REMOVAL

When wood is burned slowly, it produces tar and other organic vapours which, when combined with moisture, form
creosote. The creosote vapours condensate in a relatively cold chimney flue. As a result, creosote residues
accumulate in the flue lining.

N.B.: To minimize the frequency of chimney cleaning, buy your firewood at least one year before using it. Store it in a
dry place in order to obtain the minimum moisture rate and optimize the efficiency. Do not store wood or combustible
materials within the installation minimum clearances or the space required to reload the appliance and remove the
ashes.

When ignited, creosote produces an extremely hot fire inside the chimney.

To avoid this situation, it is important to do the turnover of wood. Inspect the chimney system at regular intervals to
determine a cleaning cycle. A weekly cleaning might be required during mild temperature periods but a monthly
cleaning should be sufficient during cold periods. If a significant layer of creosote has accumulated, it must be

removed immediately to eliminate the risk of a chimney fire.

Remember that a small hot fire is preferable to a large smouldering one to prevent creosote build-up within the
system. An emergency plan is necessary in case of a chimney fire.

It’s recommended to clean the heat exchangers thoroughly at the end of the season in order to help prevent
corrosion.

5

SMOKE DETECTOR

We highly recommend the use of a smoke detector. It must be installed at least 15 feet (4,57 m) from the appliance
in order to prevent undue triggering of the detector when reloading.

ASH DRAWER

Your appliance is equipped with an ash drawer to collect ashes produced by the combustion of wood. This drawer
must not be left open

The drawer must be cleaned regularly.

during combustion as this will cause over firing and serious damage to the furnace.

It is important that the door and the ash drawer be kept closed while the appliance is in use.
Maintain all gaskets in good condition: in case of deterioration, contact your dealer for
replacement.

ASH GRATE

You must replace the ash grate if it is damaged and a replacement may be obtained from your dealer.

3. APPLIANCE INSTALLATION

UNIT LOCATION

The furnace must be installed where outside air supply is sufficient for proper combustion. In airtight houses, it
might be necessary to install an outside air inlet (see details in: «3- INSTALLATION» COMBUSTION AIR).

The furnace must be positioned so that the connector is as short as possible in order to minimize the use of 90
elbows.

The owner must ensure a proper installation to allow a safe operation of the appliance.

For a proper installation, follow the advices below:

1. All the joints of the evacuation pipe must be secured, using three screws.

Make sure that each screw goes through the inner walls of both connectors (male and female). See
pictures below showing a male-female coupling.

PROPER INSTALLATION UNPROPER INSTALLATION

2. A minimum rise of 1/4 inch per horizontal foot must be respected.

CAUSE RESTRICTION

DAMPER

The barometric control must be adjusted so that the maximum draft measured at the furnace outlet is limited to -0.06
in. w.c. Please note that a draft higher than -0.06 in. H2O could result in an uncontrollable fire. On the other hand,

the minimum draft to be respected is -0.04 in. w.c. in the evacuation pipe on the solid fuel side, no matter what
type of furnace.

COMBUSTION AIR

In the event that the furnace and the chimney are completely cold, it might be necessary before lighting, to provide
fresh air by opening a door or a window for a few minutes.

Take note that a house constructed or renovated in order to be airtight is liable to lack fresh air which is necessary
for a proper combustion and a proper operation of heating units.

In such a case, when starting up the fire, do not operate appliances which evacuate air outside the house such as:

- Range hood

- Air exchanger

- Cloths dryer

- Bathroom fan

- Ventilated central vacuum system

NOTE:

w

y

It is recommended to install an outside air inlet of minimum 4” diameter in the room where the heating appliance is
installed (see drawing below). To do so, it is preferable to choose a wall which is not exposed to extreme winds,
according to the conditions surrounding your house.

Install the fan limit control on the support provided after securing this support on the left edge of the hot air plenum
where two holes are pre-drilled (there are four pre-drilled holes on the edge of the PSG3000, use the two that are
located farther back). Install the servo-motor on the facade above the door, on the right side (use pre-drilled holes).
The chain that links the air inlet latch to the motor must have a play of 1/8 in. When there is no call for heat, the air

inlet latch must be completely shut and the chain must be affixed to the servo-motor at “8 o’clock”.

The red switch located on the junction box controls low speed operation of the blower, in either ON (continuous
operation) or OFF modes.

SERVOMOTO

HOLES FOR FAN
LIMIT CONTROL

ELECTRIC ELEMENT

The WOOD / ELECTRIC combined model uses two separate thermostats: one thermostat controls the electric
heating, the other one controls the wood heating. With this system, the electric heating has priority over the wood
heating. When the thermostat activates the electric heating, the air inlet closes down (if opened), the blower starts and
the electric elements are successively activated per block of 5 kW. The system may be connected to an outdoor
sensor which will allow the last block of elements (5 kW) to start up only when the outside temperature is cold enough.
This will reduce the power of the systems by 5 kW during mild temperature for more economy and comfort.

When the call for electric heat is completed, the wood system will take over if the setting of the wood thermostat is
higher than that of the electric thermostat.

So, in normal bi-energy use, you should set the wood system thermostat 2
thermostat.

Take note furnaces equipped with the G10 blower have a four speed motor and furnaces equipped with the G-12
have 2 speed motot and an adjustable pulley.

If the temperature of the element exceeds the limit allowed, the thermostatic captor will disengage the elements. To
reactivate, press the red “manual reset” button on the L-170 thermodisk; find out why the temperature limit has been
exceeded (static pressure too high, fan breakage, dirty filter, etc.) before reactivating.

THERMOSTAT

The thermostat must be installed on an inside wall in a location where it is not likely to be affected by the draft
coming from an air outlet. It must be installed at a minimum of 55 inches above the floor.

N.B. The combined wood / electric model uses two thermostats and they should be installed at same height.

11

FAN CONTROL

The fan control setting may vary depending on the type of installation. The “out of service” temperature is factory
set at 110
for most installations.

It is preferable for a prolonged operation of the blower that the setting “out of service” be low enough. But a setting
“out of service” too low will cause cold air circulation. To modify the settings, move the tabs at the desired position on
the temperature scale.

The adjustment of all controls must be performed by a qualified technician. The controls setting and the blower
speed must conform to the recommendations of the “Warm Air Heating and Air Conditioning National Association”.

The red switch located on the electric unit controls the low speed (summer speed) either at the “on” or the “off”
position. For a better efficiency, we recommend to let the blower be controlled automatically when heating with wood.

o

F and the “in service” temperature is factory set at 150o F. These settings should provide a proper operation

4. OPERATING INSTRUCTIONS

Control system

On the wood furnaces only, the thermostat controls the air inlet damper. When the thermostat calls for heat, the
damper opens and the fire burns up. When the furnace gets hot enough, the combined limit control activates the
blower motor at the speed selected for wood heating.

The chain that links the air inlet damper to the motor must have a play of 1/8 inch. When there is no call for heat,
the air inlet damper must be completely closed and the chain must be affixed to the servo-motor at “8 o’clock”.

* (With all reserve on the minimum air to be increased depending on the type and quality of the combustible).

LIGHTING:

*

1. Open the door
Note: If there is already a bed of coals in the combustion chamber, go directly to PREHEATING.

2. Drop the ashes into the ash pan

3. Place one or two dry kindlings at the front of the combustion chamber

4. Place newspaper strips on top of the kindlings.

5. Cover the newspaper with more kindlings and small pieces of dry wood.

6. Add newspaper strips, then light the fire a low as possible and leave the door 1/2" (13 mm) opened. If you fail
lighting the fire, you might experience a back draft through the air inlets.

PREHEATING

1. Once the kindling is well ignited or the coals revived, put 2 or 3 fire logs in such a way that the flames can interlace
between the logs then close the door. It is important to respect these loading sequences so that the wood will burn
from the front to the back of the furnace.

2. Wait 15 to 20 minutes, then proceed with loading the furnace.

12

HEATING

1. When loading the furnace, lower the kindled pieces of wood and place them at the center of the combustion
chamber before adding new logs.

2. Do not overload. Air must circulate freely in the upper part of the furnace in order to obtain an efficient operation of
the appliance. Please note that a small hot fire will produce much less residues than a large smouldering one.

IMPORTANT: DURING THE HEATING PROCESS, REMOVE THE ASHES AND EMBERS THAT COULD
OBSTRUCT THE AIR INTAKE LOCATED BELOW THE DOOR INSIDE THE FURNACE.

PROCEDURE TO OPEN THE LOADING DOOR

TO MINIMIZE THE RISK OF A BACK DRAUGHT OPEN THE DOOR 1” AND WAIT ABOUT 10

SECONDS BEFORE OPENING COMPLETELY. THE PURPOSE IS TO STABILIZE THE

PRESSURE INSIDE THE FURNACE.

EARLY SIGNS OF OVERFIRED FURNACE

1. Roaring fire.

2. Chimney connector is glowing red.

3. Extreme heat coming from the furnace. If this occurs, DO NOT OPEN THE DOOR
completely, and wait until the glow has completely subsided.

, shut-off the air inlet opening

ALWAYS KEEP THE DOOR AND THE ASH DRAWER CLOSED

(except for lighting and maintenance).

WOOD AS HEATING FUEL

We recommend that you burn dry wood only.

There are two important factors to be considered when choosing a type of wood: the moisture content and the wood
density. Hardwood, such as maple, oak and beech will provide better results because of the high density and minimal
tar produced during combustion. It is highly recommended to use wood that has been dried at least six months. Do
not use coal as heating fuel in this appliance.

Whenever a high amount of smoke is noticed in the room, you must:

1. Open doors and windows.

2. Make sure the furnace door is closed as well as the damper (if necessary, lower the thermostat starting point or
undo the chain of the damper and close manually the barometric draft control).

3. When the furnace has cooled down, inspect the chimney to detect obstructions and consult a specialist to
determine the cause of the smoke spillage.

CARBON MONOXYDE IS A LETHAL GAS (ODOURLESS AND COLOURLESS), WHICH YOU MUST
BEWARE OF.

13

CHIMNEY FIRES

Chimney fires might occur when the fire gets extremely hot. Burning cardboard, branches or pieces of wood can
ignite the creosote residue accumulated in the evacuation flue system. The usual signs are:

1. Rumbling

2. The flue gets extremely hot

3. Flames are coming out of the chimney

In case of a chimney fire, first call your local fire department and sprinkle the roof around

the chimney with water.

Make sure that the furnace door is closed as well as the damper (if necessary, lower the thermostat starting point or
release the chain from the damper and CLOSE the barometric draft control manually).

If the fire gets uncontrollable due to an improper use or because the draft is too strong, follow the same procedure
as in a chimney fire except that you will have to OPEN manually the barometric draft control.

LOCAL FIRE DEPARTMENT.

5. MAINTENANCE

MAINTENANCE OF THE EXCHANGERS

The evacuation pipe and the heat exchangers should be inspected regularly during the burning season. Using the
scraper, clean the exchanger pipes thoroughly on a regular basis.

INSTRUCTIONS

o

1

Wait until fire is completely out before cleaning.

o

Remove the smoke pipe connector from the furnace.

2

o

Inspect the furnace’s heat exchangers (rectangular tubes) through the smoke outlet for creosote accumulation. On

3
the PSG5000, you can access the heat exchangers by removing the square panel located at the back of the furnace.

o

Using the supplied scraper, clean the heat exchangers and the combustion chamber and remove creosote residues.

4

o

Reassemble the smoke pipe connector or access panels.

5

CHIMNEY MAINTENANCE

One of the most efficient methods is to sweep the chimney, using a hard brush. Brush up and down. Soot and
creosote residue will come off the inside surface and fall at the bottom of the chimney where it can be removed easily.

The chimney must be checked regularly and if creosote has accumulated, it must be removed. Cleaning on a
monthly basis should be sufficient during the coldest months.

14

Smoke flue inspection

- The smoke flue should be inspected regularly during the heating season.

- If possible, the smoke flue should be dismantled and cleaned.

- The flue should be inspected to detect any defect.

- If no defect is noticed, put the flue back in place; otherwise, it must be replaced.

- Use only wood as a combustible.

- Seasoned hard wood logs 18” to 22” long are recommended as a combustible.

Regular maintenance is required for safe and efficient operation of a controlled-combustion heating system. Chimney,
gaskets and smoke pipes must remain in good working condition.

MAINTENANCE OF THE BLOWER MOTOR

The two bearings of the motor must be lubricated once a year using non detergent SAE 20 oil.

DO NOT OVERLUBRICATE

FILTERS

The furnace must not be operated without the filters. The air filters must be cleaned or replaced regularly. Use the
same size and preferably the same type as the original filters.

DOOR GASKET MAINTENANCE

It is important to maintain the door gasket in good condition. After a while, the gasket might sag and a door
adjustment may be required to prevent air leakage; if adjustment is not sufficient, replace the gasket.

We recommend to replace the gasket that seals the door once a year in order to maintain a good control of the
combustion for maximum efficiency and security. To replace your door gasket, remove the old gasket and glue. Clean
the surface thoroughly, apply the gasket glue and put the new gasket onto the door. Wait for at least 2 hours before
lighting your furnace.

6. REPLACEMENT PARTS

Your PSG furnace is designed to burn clean and requires minimal maintenance. It’s recommended to conduct a visual
inspection at least once a month to uncover any damage to the unit. Any damage must be repaired as soon as
possible using genuine PSG replacement parts. You can find a complete list of replacement parts on our website at

www.psg-distribution.com

11. TROUBLESHOOTING

PROBLEM

1. Sudden drop in heating

performance follows adequate
heating from first loadings.

2. Insufficient heat from first loadings,

low draft

3. Poor heating in the rooms while

hot air plenum and furnace are hot.

4. Furnace burns too much wood.

5. Fan starts too late.

6. Creosote accumulation, very

average performance.

7. Hot air plenum remains barely

warm while furnace in full operation.

CAUSES

Ash accumulation at lower intake
blocks combustion air intake and
causes deposits in heat exchanger
and flue pipes.

GENERAL NOTES

This instruction manual treats mainly of the oil burning unit of your wood/oil combination furnace.

For any additional information concerning the wood burning furnace, please consult your

installation and operation instructions manual for wood and wood/electricity furnaces.

To obtain the optimal efficiency, follow the advices below regarding the installation and operation of your
WOOD/OIL combination furnace.

Respect the local codes (when in doubt, consult your local heating appliances dealer).

Make sure that the clearances indicated in the instruction manual correspond to the specifications on the
certification plate.

Make sure that your furnace is installed in conformity with the instructions on the name plate.

All the controls adjustments must be performed by a qualified technician. The controls settings and the
fan speed must be in compliance with the recommendations of the Warm Air Heating and Air Conditioning
National Association and must respect the static pressure ranges in the warm air plenum of the furnace.

THE INSTALLATION OF THE WOOD/OIL COMBINATION FURNACE MUST BE
DONE IN ACCORDANCE WITH THE RULES OF THE AUTHORITIES HAVING
JURISDICTION AND THE CAN/CSA B-139 M-91 STANDARD FOR OIL BURNING
HEATING APPLIANCES.

The oil burning furnaces are not approved for use with combustible heavier than No.2 oil (furnace oil). DO

NOT USE GASOLINE, TRANSMISSION OIL OR OTHER TYPE OF OIL CONTAINING GASOLINE.

1. DRAFT AND CHIMNEY

The chimney must be conform to the rules of the authorities having jurisdiction and the CAN/CSA B139
M-91 & NFPA 31 standard regarding installation of oil burning heating appliances. The installation of the
connecting pipes to the oil unit must be done and approved by a qualified pipe fitter.

The barometric damper provided with the appliance must be properly installed on the flue pipe of the oil
unit. The purpose of the damper is to limit the draft, if necessary, in the oil unit evacuation pipe.

Since the evacuation pipe of the oil unit is connected to the evacuation pipe of the wood burning furnace,

the minimum draft to be respected at all times in the evacuation pipe of the wood burning side is -

0.04” W.C.

2. OIL TANK AND PIPING

The maximum capacity of the tank must be 200 gallons and the tank must be located at least 7 feet from
the burner. Local codes will govern the size of the air inlets and filling openings as well as the type of plugs
to be used. 1 1/4" IPS and 2" IPS are usually accepted as minimum dimensions for the air intake and fill
pipes, respectively. The oil line to the burner must be a 3/8" outside diameter copper tubing for runs up to
50 feet and ½” o.d. for longer runs. A manual shut-off valve and an oil filter shall follow in sequence on the

23

oil line between the oil tank and the burner. The oil line cannot be buried and must be protected adequately
to avoid any damage.

BURNER PUMP

The burner is equipped with a single stage pump. When the pump is connected to a single feeder pipe, a

maximum rise of 8 feet is allowed. This height is measured from the tank outlet level to the burner inlet.

When the rise is more than 8 feet but not exceeding 10 feet, a by-pass plug (provided with the burner)
and an oil return pipe must be installed. For more details, see “INSTALLATION INFORMATIONS”, Part
No. 21844 on the burner pump.

If the rise is higher than 10 feet, a two stage pump may be required along with an oil return pipe.

3. APPLIANCE INSTALLATION

LOCATING THE UNIT

The furnace must be installed in a location where combustion air is available in sufficient quantity. In
airtight houses, the installation of an outside air intake might be required. (See details in 3- APPLIANCE
INSTALLATION, COMBUSTION AIR).

The owner is responsible for ensuring a proper installation to allow a salubrious operation of the
appliance.

Position the furnace so that the connecting pipe is as short as possible and limit the use of 90
a minimum.

Provide sufficient clearance to permit easy access for maintenance of the filters, motors, controls and
pipe connectors.

COMBUSTION AIR

Take note that an airtight house is liable to lack the fresh air needed for proper combustion, specially if
you are using appliances that evacuate air from the house, such as:

- Range hood

- Air exchanger

- Clothes dryer

- Bathroom fan

- Central vacuum cleaning system

In that case, it is recommended to install a 4” fresh air inlet in the room or next to the room where the
heating appliance is located (see drawing below); choose a wall which is not exposed to dominant winds,
depending on the conditions surrounding your house.

FAN LIMIT CONTROL INSTALLATION ON MODEL PSG/UH-4500

The wood unit fan limit control must be installed with the mounting bracket in the warm air plenum on the
right hand side of the appliance (two holes are pre-drilled on the upper edge of the furnace to receive the
mounting bracket). The fan limit control for the oil burning unit must be installed on the upper right part of
the appliance’s front panel (a 1" diameter hole is pre-punched in order to insert the fan limit’s sensor in the
furnace).

N.B.

On the PSG/UH-4500, the wood fan limit control is the one that is attached to the junction box and

relay-transformer.

ELECTRICAL WIRING

The whole wiring from the distribution panel to the heating unit shall comply with the applicable electrical
standards and local codes. The unit should be connected to its own 15 amp/120VAC electric circuit (see
electrical diagram).

THERMOSTAT

Both the wood and oil thermostats must be installed side by side on an interior wall, in a location where
they are not affected by the air draft coming from the furnace’s blower; they must be level and at least 55
inches above the floor.

FAN CONTROL

The fan limit control settings may vary according to the type of building and heating installation; the "fan
off” setting is factory set at 100
“fan” off” setting; these settings should allow a proper operation for most installations

o

F and the "fan on” setting positioned as close as physically possible to the

31

In order for the blower to run for long enough periods, the "fan off" setting must not be set too high but
too low a setting will result in undesirable cold air circulation. To modify the settings, move the tabs to the
desired position on the temperature scale of the fan limit control.

All adjustments of the controls must be performed by a qualified technician. The controls settings and the
blower speeds must be set in accordance with the recommendations of the Warm Air Heating and Air
Conditioning National Association.

To obtain a continuous air circulation during summer months, simply turn the manual switch “ON”. The
summer switch is located on the controls junction box.

It is not recommended to let the blower run on continuous mode when heating with wood as the wood
furnace must reach a certain temperature before the blower starts to perform adequately.

COMBUSTION SAFETY CONTROL

The AFG type oil burner is equipped with an electronic control (# R7184B1032) including a pre-purge
function and a new more durable drive motor.

PRE-PURGE

When there is a call for heat, the burner’s fan will run for 15 seconds before the actual ignition takes place
to vent the combustion chamber and generate a proper draft. This will result in a smoother ignition of the oil
burner.

SAFE OPERATION

If the flame goes out while the burner is running, the CAD cell will detect it; the control will then switch to
the "RECYCLE" mode and cut the fuel supply to the burner for 60 seconds. After this delay, the control
goes back to "IGNITION" mode. If the flame goes out 3 times in a row, the control will switch to the
"LOCKOUT" mode to prevent a continuous cycling of the ignition process, which would cause a premature
sooting of the combustion chamber and smoke pipe. To deactivate the “LOCKOUT” mode, press and hold
the reset button of the control for 30 seconds.

A green diagnostic LED on the control has four states:

- On = Flame present

- Off = No flame

- 2 seconds On, 2 seconds Off = "Recycle" mode

- 1/2 second On, 1/2 second Off = "Lockout" mode TEMPORARY SHUT-OFF

By pressing and holding the reset button, the burner will shut-off until the reset button is released. Then,
the control will start over at the beginning of the normal cycle.

FOR ADDITIONAL INFORMATIONS ON OPERATION SEQUE NCES OF THE BURNER, CONSULT THE
BURNER INSTRUCTION MANUAL.

I- TIGHTEN ALL THE LOCKING SCREWS AFTER COMPLETING THE FINAL ADJUSTMENT.

N.B. – The barometric damper provided with the appliance must be properly installed on the flue pipe of the

oil burning unit. The purpose of the damper is to adjust the draft in the evacuation pipe of the oil
burning unit to the recommended level. Since the evacuation pipe of the oil burning unit is connected
on the evacuation pipe of the wood burning furnace, the minimum draft to be respected is 0.04"
W.C. in the evacuation pipe of the wood burning side, at all time. In fact, a barometric damper

that would be opened too wide could cause an important loss of draft in the evacuation pipe
of the wood burning furnace.
