2.1) Safety Rules:

Your unit is built to provide many years of safe and dependable
service providing it is properly installed and maintained. However,
abuse and/or improper use can shorten the life of the unit and create
hazards for you, the owner.

The U.S. Consumer Product Safety Commission recommends

that users of oil-burning appliances install carbon monoxide

detectors. There can be various sources of carbon monoxide in

a building or dwelling. The sources could be gas-fired clothes

dryers, gas cooking stoves, water heaters, furnaces, gas-fired

fireplaces, wood fireplaces, and several other items. Carbon

monoxide can cause serious bodily injury and/or death.

Therefore, to help alert people d potentially dangerous carbon

monoxide levels, you should have carbon monoxide detectors

listed by a nationally recognised agency (e.g. Underwriters

Laboratories or International Approval Services) installed and

maintained in the building or dwelling (see Note).

b.

There can be numerous sources of fire or smoke in a building or

dwelling. Fire or smoke can cause serious bodily injury, death,

and/or property damage. Therefore, in order to alert people of

potentially dangerous fire or smoke, you should have fire and

smoke detectors listed by Underwriters Laboratories installed

and maintained in the building or dwelling (see Note below).

Your unit is equipped with safety devices that may keep it from
operating if sensors detect abnormal conditions such as clogged

exhaust flues.

If the structure will be unattended during cold weather you should take
these precautions.

a. Turn off main water supply into the structure and drain the water

lines if possible. Open faucets in appropriate areas.

b.

Have someone check the structure frequently during cold
weather to make sure it is warm enough to prevent pipes from
freezing. Suggest they call a qualified service agency, if
required.

2.3) Installation regulation:

All local and national code requirements governing the installation of
oil burning equipment, wiring and flue connections MUST be followed.
Some of the codes that may be applicable are:

2.2) Freezing Temperature and Your

Structure:

Freeze warning.

Turn off water system.

If your unit remains shut offduring cold weather the
water pipes could freeze and burst, resulting in

serious water damage.

Only the latest issues of the above codes should be used.

3) LOCATING THE FURNACE

CAUTION

Check carefully your furnace upon delivery for any
evidence of damage that may have occurred during

shipping and handling. Any claims for damages or lost
parts must be made with the Transport Company.

As this unit may be installed as an upflow, counterflow or horizontal
furnace (right or left), it may be located in a basement, on the same
level as the area to be heated, suspended, or in a crawlspace. In any
case, the unit should always be installed level.

4) VENTING

In a basement, or when installed on the floor (as in a crawlspace), it
is recommended that the unit be installed on a concrete pad that is

1" to 2" thick.

When installed in the counterflow position, this furnace must not be
installed on combustible flooring, unless the approved sub-base is
used (Model # DFB-101). The flue pipe must exit the cabinet
through one of the panel opening, then extended up the side of the

furnace. Care must be taken to insure that the clearances from the
flue pipe to combustible construction are maintained.

Also, it is recommend to use the flue pipe guard kit
(Model # FPG-101 or # FPG102) to insure that a fire hazard

condition does not exist.

When installed in a horizontal position, the furnace may be
suspended by using an angle iron frame, as long as the total weight
of both the furnace and the frame are allowed for in the support
calculations. (Other methods of suspending are acceptable.) When
installed in the Horizontal Position, this furnace must not be installed

on combustible flooring, unless the approved sub-base is used
(Model # HFB-101).

This furnace is approved for reduced clearances to combustible
construction. Therefore, it may be installed in a closet or similar

enclosure.

The required minimum clearances for this furnace in all
positions are specified in tables # 3.2 and 3.3.

The furnace should be located as close as possible to the chimney
or vent in order to keep vent connections shorts and direct. The
furnace should also be located as near as possible to the center of
the air distribution system.

Do NOT operate furnace in a corrosive atmosphere
containing chlorine, fluorine or any other damaging

I CAUTION

chemicals. Refer to Part 1, section 5.2.

Failure to properly vent this furnace can result in

property damage, personal injury and/or death.

CAUTION

When the furnace (chimney installation) is co-vented
with other combustion appliances such as a water

heater, the allowable venting materials (i.e. L-Vent etc.)
for use with those appliances should also be

investigated.

Poison carbon monoxide gas hazard

Never install a hand operated damper in the vent

pipe. However, any Underwriters Laboratories
listed electrically operated automatic type vent
damper may be installed if desired. Be sure to

follow instructions provided with vent damper.

Read and follow all instructions in this section.

Failure to properly vent this furnace or other
appliances can result in property damage, personal
injury and/or death.

Venting of the furnace should be to the outside and in accordance
with local codes or requirements d the local utility.

Electrical shock hazard.

This furnace is not watertight and is not designed
for outdoor installation. This furnace shall be

installed in such a manner as to protect the

electrical components from water.
Outdoor installation would lead to a hazardous

electrical condition and to premature furnace
failure, property damage, bodily injury or death.

OIL FIRED APPLIANCES SHALL BE CONNECTED TO FLUES
HAVING SUFFICIENT DRAFT AT ALL TIMES TO ENSURE SAFE
AND PROPER OPERATION OF APPLIANCE.

For additional venting information refer to ANSl/NFPA 211 Chimney,
Fireplaces, Vents and Solid Fuel Burning Appliances and/or CSA

B139 Installation Code.

This furnace is certified for use with Type '%" vent (maximum flue
gas temperature 575°F). The flue pipe clearance knockout in the

front top or side panel should be removed. Install the flue elbow so
that it exits the furnace cabinet through that opening.

Pre-instatlation vent system inspection:

Before this furnace is installed, it is highly recommended that any
existing vent system be completely inspected.

For any chimney or vent, this should include the following:

a. Inspection for any deterioration in the chimney or vent. If

deterioration is discovered, the chimney must be repaired or
the vent must be replaced.

b. Inspection to ascertain that the vent system is clears and free

of obstructions. Any blockage must be cleared before installing
this furnace.

¢. Clearing the chimney or vent if previously used for venting a

solid fuel burning appliance or fireplace.

d. Confirming that all unused chimney or vent connections are

properly sealed.

e. Verification that the chimney is properly lined and sized per the

applicable codes, (Refer to list of codes on page 3.)

Masonry Chimney:

This furnace can be vented into an existing masonry chimney. This
furnace must not be vented into a chimney servicing a solid fuel-
burning appliance. Before venting this furnace into a chimney, the
chimney must be checked for deterioration and repaired if
necessary. The chimney must be properly lined and sized per local

or national codes.

Poison carbon monoxide gas hazard.

Comply with ANSI/NFPA (in U.S.) or CSA (in
Canada) standard for the installation of Oil Burning

Equipment and applicable provision of local
building codes to provide combustion and

ventilation air.

Failure to provide adequate combustion and
ventilation air can result in personal injury and/or

death.

If the furnace is vented into a common chimney, the chimney must
be of sufficient area to accommodate the total flue products of all
appliances vented into the chimney.

The following requirements are provided for a safe venting system:
a. Ensure that the chimney flue is clear of any dirt or debris.

b. Ensure that the chimney is not servicing an open fireplace.
C. Never reduce the pipe size below the outlet size of the furnace.

d. All pipes should be supported using the proper clamps and/or

straps. These supports should be at least every four (4) feet.

e. All horizontal runs of pipe should have at least a 1/4" per foot of

upward slope.

f. All runs d pipe be as short as possible with as few turns as

possible.

g. Seams should be tightly joined and checked for leaks.
h. The flue pipe must not extend into the chimney but be flush

with the inside wall.

i. The chimney must extend three (3) feet above the highest point

where it passes through a roof of a building and at least two (2)
feet higher than any portion of a building within a horizontal

distance of ten (10) feet. It shall also be extended at lest five
(5) feet above the highest connected equipment flue collar.

j. Check local codes for any variance.

Factory Built Chimneys:

May use listed factory built chimneys. Refer to chimney
manufacturer's instructions for proper installation.

5.1) General:

Oil furnaces must have an adequate supply of combustion air. It is
common practice to assume that older homes have sufficient
infiltration to accommodate the combustion air requirement for the

furnace. However, home improvements such as new windows, doors,
and weather stripping have dramatically reduced the volume of air
leakage into the home.

When this furnace is installed in a closet or enclosure, two (2)
ventilation openings are required for combustion air. The openings

should be located about 6" from the top and the bottom of the
enclosure at the front of the furnace. Table # ! indicates the

minimum ventilation openings dimensions required.

TABLE # 1

Input Length Height

Home air exhausters are common. Bathroom and kitchen fans, power
vented clothes dryers, and water heaters all tend to create a negative
pressure in the home. Should this occur, the chimney become less

and Iess effective and can easily downdraft.

4.1) BAROMETRIC DRART CONTROL

The barometric draft control shipped with furnace MUST be used with
furnace to ensure proper operation. Instructions for installing control
are packed with control.

5) AIR FOR COMBUSTION

Heat recovery ventilation (HRV) systems are gaining in popularity. The
HRVs are not designed to supply combustion air. If not properly
balanced, a serious negative pressure condition could develop in the

dwelling.

5.2) Contaminated Combustion Air :

Installation in certain areas or types of structures will increase the
exposure to chemicals or Halogens which may harm the furnace.

These instances will require that only outside air for combustion.

The following areas or types of structures may contain or have
exposure to the substances listed below. The installation must be
evaluated carefully as it may be necessary to provide outside air for

combustion.

a. Commercial building.
b. Building with indoor pools.
c. Furnaces installed near chemical storage areas.

6) OIL TANKS AND LINES

Check your local codes for the installation of the tank and accessories.

A manual shut-off valve and an oil filter shall follow sequence from
tank to burner. Be sure that the oil line is clean before connecting to
the burner. The oil Iine should be protected to eliminate any possible

damage. Installations having the fuel oil tank below the burner level
must employ a two pipe fuel supply system with an appropriate fuel
pump (more than 8' lift use 2 stage pump and more than 16' an
auxiliary pump).

a. Set your voltmeter to line voltage.
b. Place one prong on your grounded electric entry box and one

prong on the black wire.
c. Read the voltage.
d. If the voltage is zero, check the white wire. If Iine voltage shows.

Reverse the 115-volt leads entering the furnace junction box.

7) BURNER INSTALLATION

I IMPORTANT: Burner must always be installed in the

upright position with the ignition control on top.

Mounting the burner:

a.

The warm air furnace burner mounting plate has a four bolts
configuration.

b.

Position the mounting gasket between the mounting flange and
the appliance burner mounting plate. Line up the holes in the
mounting flange with the studs on the appliance mounting plate

and securely bolt in place.

After the burner is mounted:

a. Remove drawer assembly or air tube combination
b. Install nozzle (see specifications)

c. Confirm electrode settings
d. Make the electrical connections

e. Complete oil line connections

The burners are provided with the highest capacity USGPH nozzle
installed. If another size nozzle, or replacement nozzle is required, use
the nozzle spray angle, type and manufacturer recommended in Table
#3. Note that all nozzle-marked sizes are based on a pump pressure
of 100 psi.

Always select nozzle sizes by working back from the actual desired
flow rate at operating pressure, and not by the nozzle marking.

Air and turbulator settings:

Before starting the burner for the first time, adjust the air and turbulator
settings to those listed in the Table #3. Once the burner becomes
operational, final adjustment will be necessary.

Fuel supply system:

Fuel Specifications

I NOTE: Use No.1 or No.2 Heating Oil (ASTM D396) or in Canada, useNo.! or No.2 Furnace Oil.

Before starting the burner be sure the fuel tank is adequately filled with
clean oil.

Do not turn on the burner until you have checked the

I CAUTION

polarity

Checking the polarity:

The oil burners used on the furnaces have solid state control systems
which makes them sensitive to the proper connections of the hot and
neutral power lines. The controls will be damaged if the two lines are

reversed.
