LOCATION

WARNING

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.

CAUTION

For an attic installation it is important to keep insulation 12" or more away from any furnace openings. Some types of insulating materials may be combustible.
Air for Combustion and Ventilation:
This furnace should be installed in a location in which the facilities for ventilation permit satisfactory combustion of oil, proper venting and the maintenance of ambient temperature at safe limits under normal conditions of use. The location should not interfere with proper circulation of air within the confined space.
In addition to air needed for combustion, process air shall be provided as required for: cooling of equipment or material, controlling dew point, heating, drying, oxidation or dilution, safety exhaust and odor control.
In addition to air needed for combustion, air shall be supplied for ventilation, including all air required for comfort and proper working conditions for personnel.
The barometric draft regulator, included with the furnace, shall be installed in the same room or enclosure as the furnace in such a manner as to prevent any difference in pressure between the regulator and the combustion air supply.
Air requirements for the operation of exhaust fans, kitchen ventilation systems, clothes dryers, and fireplaces shall be considered in determining the adequacy of a space to provide combustion air requirements.
This furnace is approved for reduced clearances to combustible construction, therefore, it may be installed in an alcove or similar enclosure. It is also approved for
Issue 9413
20142901 218
Page 3
In unconfined spaces in buildings of conventional frame, brick or stone construction infiltration may be adequate to provide air for combustion, ventilation and dilution of flue
/--xgases. This determination must be made on an individual
( hstallation basis and must take into consideration the
overall volume of the unconfined space, the number of windows and ventilation openings, the number of doors to the outside, internal doors which can close off the unconfined space and the overall tightness of the building construction.
Many new buildings and homes (and older ones that have been weatherized) must be considered as being tight construction and, therefore, infiltration will not be sufficient to supply the necessary air for combustion and ventilation.
A building can be considered as being of tight construction when:
a. Walls and ceilings exposed to the outside
atmosphere have a continuous water vapor retarder with a rating of one perm or less with openings gasketed or sealed and /or
b. Weatherstripping has been added on operable
windows and doors, and/or
c. Caulking or sealants are applied to areas such as
joints around window and door frames, between sole plates and floors, between wall-ceiling joints, between wall panels, at penetrations for plumbing, electrical and fuel lines and at other openings.
If combustion and ventilation air must be supplied to an
unconfined space from outside, an opening with a free area of not less than one square inch per 1,000 BTU per
hour of total input of all appliances within the unconfined space (but not less than 100 square inches) must be provided. This opening must be located such that it can
not be blocked at any time.
When ducts are used to supply air, they must be of the same cross sectional area as the free area of the openings to which they connect.
The minimum dimension of rectangular air ducts must not be less than 3 inches.
In calculating free area, consideration shall be given to the blocking effect of louvers, grilles or screens protecting openings. Screens used shall not be smaller than 1/4 inch mesh and shall be readily accessible for cleaning.
If the free area through a design of louvered or grille is known, it shall be used in calculating the size design and free area specified. If the design and free area is not known, it may be assumed that wood louvers will have 20 percent free area and metal louvers and grilles will have 60 percent free area. Louvers shall be fixed in the open position or interlocked with the furnace so they are opened automatically at furnace start-up and remain open during furnace operation.

WARNING

Do not block the combustion air openings in the furnace. Any blockage will result in improper combustion and may result in a fire hazard and/or cause bodily harm.

Ductwork Recommendations:

The proper sizing of warm air ducts is necessary to insure
satisfactory furnace operation. Ductwork should be in
accordance with the latest editions of NFPA-90A
(Installation of Air Conditioning and Ventilating Systems)
and NFPA-90B (Warm Air Heating and Air Conditioning
Systems) or Canadian equivalent.
For a confined space, where air is taken from an interior
space, two permanent openings of equal area are
required. One opening must be within 12" of the ceiling
and the other within 12" of the floor. Each opening must
have a free area of at least 1 sq. inch per 1,000 BTU of
total input rating but no less than 100 sq. inches.
If outside air is supplied to a confined space, then the two openings must be equal and located as above and the free area of each must be:
1. 1 sq. inch per 4,000 BTU of total rating when the air is directly communicated from the outdoors.
2. 1 sq. inch per 4,000 BTU of total input rating
\ when the air is brought in through vertical ducts.
3. 1 sq. inch per 2,000 BTU of total input rating when the air is transferred through horizontal ducts.
The supply ductwork should be attached to the flanged
opening provided at the discharge end of the furnace. See Figure 7 for the dimensions of this opening.
Knockouts are provided on both sides of the furnace to facilitate the side panel cut out required to assemble the return ductwork. This can be done on either the right or
the left side of the furnace. See Figure 7 for location and
dimensions. Undersized cut-outs will adversely affect the airflow capability of the furnace.
When the provided external filter rack is used, the return air duct should be attached as per Figure 9.
Provision is also made on this furnace for a bottom return
air duct. (We recommend the use of this opening for
horizontal installations.) The specifications for this
ISSUE 9413
20142901 318
Page 4
opening are also illustrated in Figure 7. If the bottom return is not used, a field-supplied galvanized steel filler plate should be used to block off the opening.
The following recommendations should be followed when installing the ductwork:
1. Install locking type dampers in ail branches of the individual ducts to balance out the system. Dampers should be adjusted to impose the proper static at the outlet of the furnace.
2. A flexible duct connector of noncombustible material should be installed at the unit on both the supply and return air system. In applications where extremely quiet operation is necessary, the first 10 feet (if possible) of supply and return ducts should be internally lined with acoustical material.

WARNING

The coil MUST be installed on the air discharge side of the furnace. Under no circumstances should the air flow be such that cooled, conditioned air can pass over the furnace heat exchanger. This will cause condensation in the heat exchanger and possible failure of the heat exchanger which could lead to a fire hazard and/or a hazardous condition which may lead to bodily harm. Heat exchanger failure due to improper installation may not be covered by warranty.
2. In parallel flow installation, dampers must be provided to direct air over the furnace heat exchanger when heat is desired and over the cooling coil when cooling is desired.
3. In cases where the return air grille is located close to the fan inlet, there should be at least one 90° air turn between fan inlet and grille. Further reduction in sound level can be accomplished by installing acoustical air turning vanes or lining duct as described in item 2 above.
4. When a single air grille is used, the duct between grille and furnace must be the same size as return opening in furnace.

CAUTION

Return air grilles and warm air registers must not be obstructed.

WARNING

When supply ducts carry air circulated by the furnace to areas outside the spaces containing the furnace, the return air shall also be handled by a duct sealed to the furnace casing and terminating outside the space containing the furnace. Incorrect ductwork termination and sealing will create a hazardous condition which could lead to bodily harm.

IMPORTANT: The dampers should be adequate to

prevent cooled air from entering the furnace, and if manually operated, must be equipped with the means to prevent operation of either the cooling unit or furnace unless the damper is in the full cool or heat position.

Venting Instructions:

Venting of the furnace should be to the outside and in accordance with local codes or requirements of the local utility.
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 ANSI/NFPA 211 Chimney. Fireplaces. Vents and Solid Fuel Burning Appliances and/or CSA B139 Installation Code.
When installing the furnace with cooling equipment for
year round operation, the following recommendations must be followed for series or parallel air flow:
1. In series air flow applications, the coil is mounted after the furnace in an enclosure in the supply air stream. The furnace blower is used for both heating and cooling air flow.
This furnace is certified for use with Type "L" vent
(maximum flue gas temperature 575°F).

WARNING

Do not use this furnace as a construction heater. Use of this furnace as a construction heater exposes the furnace to abnormal conditions, contaminated combustion air and the lack of air filters. Failure to follow this warning can lead to premature furnace failure and/or vent failure which couid result in a fire hazard and/or bodily harm.

WARNING

Installation of this furnace in an area where it will receive contaminated combustion air must be avoided. Such contamination would include the following: ammonia, chlorine, hydrogen sulfide, halogenated hydrocarbons, carbon tetrachloride, cleaning solvents, hydrochloric acid, water softening chemicals and other similar chemicals. Failure to follow this warning will lead to premature rusting of the heat exchanger and possible premature furnace failure and/or vent failure which couid result in a fire hazard and/or bodily harm.
Operational Checkout: DO NOT START THE BURNER UNLESS THE BLOWER
ACCESS DOOR IS SECURED IN PLACE.
Recommended Installation
Practices and
Combustion Check:
In order to obtain the optimum performance from the oil burner, the following set-up procedures must be followed:
1. A test kit (Bacharach No. 5022 kit or equivalent) to measure the smoke, stack draft, over-fire draft, COj, and stack temperatures must be
used in order to obtain the proper air band setting. Although all of the above measurements are required for optimum set up
and efficiency data, the most important readings that must be taken are the smoke number, over the fire draft and stack draft.
2. The proper smoke number has been established by engineering tests to be between 0 & 1. This degree of smoke emission is commonly referred to as a "Trace" of smoke. It is recommended to use a Bacharach true spot smoke test set or equivalent.
3. In order to ensure the proper draft through the furnace, a barometric draft regulator, which is supplied with the furnace, must be installed as close to the outlet of the furnace as possible. In order for this device to function properly, the barometric damper must be mounted with the hinge pins horizontal and the face of the damper vertical (see instructions included with damper). The draft regulator should be adjusted after the furnace has been firing for at least five minutes and the stack draft should be measured and set between -.025" wc and
-.035"wc. The draft should be checked with a
Bacharach MZF draft gauge or equivalent.
The installation of the furnace is now complete and the
operational checkout may be performed.
ISSUE 9413
20142901 718
Page 8
4. The over the fire draft, which is taken through the hole that is provided in the observation door, is a measurement that is necessary to determine if there is a blockage between the oil burner and the flue outlet.
There should be between a .005"wc to .020"wc pressure drop through the furnace. This would set the range of the over the fire draft between
-.01 "wc to -.03"wc. A reading above -.01 "wc, for example +0.1 "wc, would indicate that the furnace is in an extremely high pressure condition in the primary section. This condition
may be caused by excessive combustion air
due to the air band being too wide open or a
lack of flue draft (chimney effect) or some other blockage, such as soot, in the secondary section of the heat exchanger.
5. The CO2 and stack temperature instruments will enable you to obtain the data that is required to
determine the thermal efficiency of the furnace.
Although this information is nice to have, it is not essential in the basic set up of the furnace.
6. An oil filter should be installed as close to the burner as possible with ail oil burners and is essential on the lower firing rate burners. We recommend the use of a low pressure drop oil filter such as the General
Filter, Inc . model #1A-25A or equivalent. It is critical that the oil capacity be equivalent or greater than the fuel pump gear capacity. For a two pipe system this is 25gph.
7. The oil pressure regulator is factory set to give nozzle oil pressures of 100PS1G. The firing
rate noted on the nameplate may be obtained with "standard" nozzles by adjusting the pump pressure as noted on the chart below or noted
on the label on the furnace. NOTE: This appliance is equipped with one of the oil burners as listed on the chart below and rating label on the furnace. Use the nozzle listed for that specific oil burner.
On a new installation the air entrapped in the oil
line leading from the tank to the nozzle must be
thoroughly purged in order to prevent excessive
after drip. The oil pump is provided with a
special fitting that will enable you to purge any
air between the tank and oil pump. The proper
procedure for performing this operation is as
follows:
Place a piece of clear plastic 1/4" dia. tubing
over the purge fitting on the oii pump. Start the
oil burner, then open the purge fitting and allow
the burner to run until the purge tube is
completely free of air bubbles. At this point
tighten the purge fitting which will allow the oil
to run to the nozzle and fire the burner. (If the
purging takes longer than 15 seconds and no
flame has been established the burner will stop.
Push the reset button on top of Primary Control
to restart burner.) For detailed information on
operation of primary control refer to instructions
included with furnace.
8. After all the set up procedures mentioned
above have been completed, the burner should
be allowed to operate and an inspection mirror
should be used to observe the flame pattern.
Any irregularities such as burning to one side or
pulsating flame patterns should be corrected by
changing the nozzle.

MAINTENANCE

This furnace should never be operated without an air filter. Filters should be cleaned at least twice a year.
Figure 2

Limit Control Check:

After the furnace has been in operation for at least 15
minutes, restrict the return air suppiy by blocking the filters or closing the return registers and allow the furnace to shut down on high limit. The burner will shut OFF and the main blower should continue to run.
Remove the restriction and the burner should come
back on in a few minutes.
For Year Round Air Conditioning; The furnace is designed for use in conjunction with
cooling equipment to provide year round air conditioning. The blower has been sized for both
heating and cooling, however, the fan motor speed may
need'to be changed to obtain the necessary cooling air flow.
Heating: The blower speed is factory set to deliver the required
air flow at normal duct static pressure.

Cooling:

The blower speed may be adjusted in the field to deliver the required air flow, for cooling application, as outlined in Figure 6.
To avoid personal injury, make sure the electrical supply power is "OFF" before servicing.
ALWAYS KEEP THE MAIN OIL VALVE TURNED OFF, IF THE BURNER IS SHUT DOWN FOR AN EXTENDED PERIOD OF TIME.

WARNING

Before performing any service functions, unless operations specifically require the power to be on, make sure ail utilities are turned "OFF" upstream of the appliance. Failure to comply with this warning will cause a fire hazard and/or bodily harm.
Periodic oiling of the blower motor may be necessary. Check for instructions on the inside of your blower compartment door.
To maintain proper performance, the oil burner nozzle must be replaced once a year. Contact your dealer serviceman if you are unsure of this procedure.
The procedure for nozzle installation and/or replacement is outlined in the oil burner instruction manual which came with the furnace. For ease of maintenance, the oiling procedure for the burner motor, as outlined in the burner manual, should be performed at this time.
After replacement of the nozzle, the burner should be adjusted in accordance with the "COMBUSTION CHECK" section of the instruction.
Ordinarily, it is not necessary to clean the heat exchanger or flue pipe every year, but it is necessary to have your oil burner serviceman check the unit before each heating season to determine whether cleaning or replacement of parts is required.

Constant Blower Switch:

This furnace is equipped with a constant iow speed blower option. Whenever the room thermostat is not calling for heating or cooling, the blower will run on low speed in order to provide air circuiation. If this constant blower option is not desired, the rocker switch on the side of the controi box may be used to "turn off" the constant speed.
If cleaning is necessary, the following steps should be performed:
1. Turn "OFF" all utilities upstream of the furnace.
2. Disconnect the flue pipe.
3. Remove the collar on the flue connection.
ISSUE 9413
20142901 918

A filter and filter rack is supplied with the furnace.
It is NECESSARY THAT ALL FURNACES BE
EQUIPPED WITH A FILTER.
)
When filter rack is used on side of furnace:
1. Filter rack may be mounted on either side of furnace.
2. The filter rack is made up of four (4) pieces - a top and bottom (which are the same), and the rear and access panels (which are the same). (Use the shorter two rear/acess panels-discard the long pair.)
clearance holes in the filter rack top, bottom, and rear panels. DO NOT SCREW THE ACCESS PANEL IN PLACE!
4. To fasten return air duct to filter rack, first cut a notch in the return air duct (for filter access panel) to dimension shown in detail. Then slide duct over filter rack.
5. Remove access panel, slide filter in piace, then replace access panel.
Minimum filter size and suggested filter material:
(If different type filter is used, it must be an equivalent high airflow capacity.) 38'/4' X 24/i'
3. Using corner indentations as a guide, cut out the selected side duct return opening (See Figure 7).
4. Clip the filter rack pieces together, as shown in
Figure 9.
5. Remove the rear-most sheet metal screw
(approximately 10" from the front of the unit) from the base. Align the second hole from the front of the filter rack bottom piece with the base hole and
reinsert the screw. (The frame should be centered over the knockout opening.)
6. Hold the filter rack against the unit (make sure it is
; square) and drill the remaining holes in the side of
the unit located according to the clearance holes in the filter rack top, bottom, and rear panels. DO
NOT SCREW THE ACCESS PANEL IN PLACE!
7. To fasten return air duct to filter rack, first cut a notch in the return air duct (for filter access panel)
to dimension shown in detail. Then slide duct over filter rack.
8. Remove metal rod from filter. Trim 4W' from width
of filter (24Vf to 20VJ'). Reinsert rod into filter at an angle, so that it does not extend past sides of filter.

WARNING

Never operate unit without a filter or with filter access door removed. Failure to adhere to this warning could lead to a hazardous condition which could lead to equipment damage and bodily harm.

Keeping Filters Clean

As a homeowner, this is your most important
responsibility. A dirty filter reduces the efficiency of
your system, causes erratic performance of controls
and could result is damage to the motor or heating element.
1. Inspect filters at regular intervals depending upon dirt conditions. For new homes, check filters every week for 4 consecutive weeks. In all cases, inspect your filters at least every 3 to 4 weeks when the system is in constant operation. Replace or clean filter at least at the beginning of each season (heating and cooling) and thereafter as needed.
1. Clip the filter rack pieces together, as shown above. (Use the longer two rear/acess panels-discard the
shorter pair.)
2. Position the rack centered over the opening in the supply end of the furnace, with access panel toward
; front of unit.
3. Hold the filter rack against the end of the unit
(make sure it is square) and drill the mounting holes in the end of the unit according to the
2. If the permanent filter supplied with the filter rack becomes dirty, it can be cleaned with cold water and soap.
Be sure that the filter is thoroughly dry before
installing back into the .furnace.

USER'S INFORMATION

Here's How Your Heating System Works

The furnace operates automatically. It is controlled by a thermostat which you set at the temperature most comfortable to you. When the inside temperature drops below this setting, your thermostat will turn on the heating system.
When the thermostat calls for heat, power from the transformer energizes the fan control board. The fan control energizes the ignition control. The ignition control will light the burner automatically.
The electronic fan control will automatically turn on the blower after 30 seconds. Fan "ON" control is not adjustable. The air moved over the heat exchanger by the blower is warmed and passes through the ducts to the room registers.
When the thermostat is satisfied, the circuit is de energized and the primary control shuts off the burner. The blower continues to run until the selectable fan off time period has expired.
The heat sensing switch performs as the furnace high temperature limit switch. If the furnace overheats for any reason, the limit switch opens, breaking the circuit to the burner. The blower motor will be energized and as the unit cools the limit switch will close. This will relight the burner and unless the overheating condition is corrected, the furnace will cycle on limit.
This unit is equipped with an interrupted ignition electronic control. If the main burner does not ignite within 15 seconds from the call for heat, the conirol will go into lockout. The red button on top of the control must be depressed for 3 seconds in order to reset the control. The control can not be reset from the room thermostat.
1. Open all warm air registers and make sure that all return air grills are unobstructed.
2. If a humidifier is installed with your system, open the water supply valve.
3. Set the thermostat to its lowest setting.
4. Turn "ON" the electric power to the furnace.
5. Open the oil supply valve.
6. Check all connections to insure there are no leaks.
