Air for combustion and ventilation
Adequate combustion and ventilation air ensures
proper combustion and reduces risk of severe
personal injury or death from possible flue gas
leakage and carbon monoxide emissions.
Do not install exhaust fan in furnace room.
Consider building construction
Older buildings with single-pane windows, minimal weather-stripping
and no vapor barrier often provide enough natural infiltration and
ventilation without dedicated openings.
New construction or remodeled buildings are most often built tighter.
Windows and doors are weather-stripped, vapor barriers are used
and openings in walls are caulked. As a result, such tight
construction is unlikely to allow proper natural air infiltration and
ventilation.
For buildings with tight construction, provide openings directly to
outside or to a ventilated crawl space or attic. Size the openings to
the same specifications as for the furnace location per the following
paragraphs.
Follow state, provincial or local codes when sizing adequate
combustion and ventilation air openings. In absence of codes, use
the following guidelines when furnace is in a confined room (defined
by NFPA 31 as less than 7200 cubic feet per 1 GPH input of all
appliances in area. A room 8 ft. high x 30.0 ft. x 30.0 ft. is 7200 cu.
ft.).
Provide two permanent openings
Openings locations
One within 12 inches of ceiling, one within 12 inches of floor.
Minimum height or length dimension of each rectangular opening
should be at least 3 inches.
When inside air is used:
Each opening must freely connect with areas having adequate
infiltration from outside. Each opening should be at least 140 sq. in.
per 1 GPH input (1 sq. in. per 1000 BTU input) of all fuel-burning
appliances plus requirements for any equipment that can pull air
from room (including clothes dryer and fireplace).
When outside air is used:
Connect each opening directly, by ducts to the outdoors, or to crawl
or attic space that freely connects with outdoors. Size per below:
 Through outside wall or vertical ducts – at least 35 sq. in. per 1
GPH input (1 sq. in. per 4000 BTU input) of all fuel burning
appliances plus requirements for any equipment that can pull air
from room (including clothes dryer and fireplace).
 Through horizontal ducts – at least 70 sq. in. per 1 GPH furnace
input (1 sq. in. per 2000 BTU input) of all fuel-burning appliances
plus requirements for any equipment that can pull air from room
(including clothes dryer and fireplace).
 Where ducts are used, they should have the same cross-
sectional area as free area of openings to which they connect.
Compensate for louver, grille or screen blockage when
calculating free air openings. Refer to the manufacturers’
instructions for details. If unknown, use:
 Wood louvers, which provide 20-25% free air.
 Metal louvers or grilles, which provide 60-75% free air.
Lock louvers in open position or interlock with equipment to
prove open before furnace operation.
Basement installations
When the furnace is located in an unconfined space, such as an
unpartitioned basement, adequate air should normally be available
without additional openings. An unconfined space is defined as one
having no less than 50 cubic feet room volume per 1,000 BTU/h
input of all appliances in the space.
If the house is of tight construction, provide air openings to the
basement directly from outside or from a ventilated attic. Size the
openings as described above under “When outside air is used”.
Closet installations – special NOTICE
Openings in closet doors
Provide TWO openings – one within 6 inches of top of closet door,
the other within 6 inches of the bottom of closet door.
EACH opening must be at least 24 inches wide by 12 inches high.
Advise homeowner that the openings to the closet
must never be obstructed or blocked in any way.
Failure to provide adequate air for combustion and
ventilation could result in severe personal injury,
death or substantial property damage.

Inspect & prepare furnace
Remove furnace from carton
Remove the furnace from its shipping carton and inspect thoroughly.
Remove access panels to inspect the furnace interior.
Immediately file a claim with the transportation
company if you discover concealed damage.
Do not install or attempt to operate the furnace if the
heat exchanger, burner or controls have been
damaged. Immediately contact your furnace
supplier. Operating a damaged furnace could result
in severe personal injury, death or substantial
property damage.
Prepare burner
Remove the burner from its shipping carton and inspect thoroughly.
Read the burner manual and follow instructions for preparing and
installing the burner.
Install the correct nozzle for the required firing rate, using the burner
manual shipped with the burner. Follow the burner manual
instructions for nozzle installation. Verify the correct setting of
electrodes after nozzle and burner oil tube assembly are in place.
Openings in walls, floor & ceiling
General
Ensure that the finished door opening to the furnace room is large
enough to install and remove the furnace, water heater or any other
appliances in the room.
Before placing furnace in a closet or small room, cut all openings
required in floor, ceiling or walls for ducts and vent. This will simplify
the work and prevent construction dust from entering the furnace
heat exchanger.
Verify that all clearances to combustible construction
and for service accessibility will be met. The vent
must be no closer than 18 inches to any combustible
surface unless a type “L” double-wall vent pipe is
used or the vent is constructed per the requirements
of the NFPA 31. Provide a ventilated thimble per all
applicable codes where vent pipe passes through
wall or ceiling. Failure to comply could result in
severe personal injury, death or substantial property
damage.
Duct locations and sizing
Verify that the size of the supply and return duct system is sufficient
for the application. The pressure drop through the duct system must
not exceed 0.2” water column. The total drop through the duct
system and air conditioning condensing coil (if used) must not
exceed 0.5” water column.
See suggested duct sizing in this manual. For more detailed sizing
information, refer to ACCA Manual D.
Openings … (continued)
Supply and return ducts
You must install a return air duct, sealed to the furnace, even if no
return manifold is used. Cut the required opening for the supply air
duct in the floor of the room before placing the furnace.
Verify that the filter will be easily accessible for
removal after the furnace is in place.
Install furnace and burner
Place furnace
Place the furnace in the desired location. Measure clearances and
verify per page 3 or table 1 of this manual.
Level the furnace using a spirit level on the front and one side.
Inspect combustion chamber
Inspect the combustion chamber. Verify that it is in good condition
and correctly positioned inside the heat exchanger. The burner
opening in the chamber must align with the burner heat exchanger
opening.
The combustion chamber is constructed of ceramic
fiber materials. See the WARNING information on
page 21 of this manual. Comply with these
instructions when handling any ceramic fiber or
fiberglass materials. Failure to adhere to these
guidelines could result in severe personal injury or
death.
Insert burner
Following the burner manual instructions, install the burner and its
gasket in the burner opening. Make sure the burner passes through
the opening in the combustion chamber and does not protrude more
than ¼inch into the chamber.
Secure the burner in place with the four nuts and washers provided.
Wire and pipe fuel to the burner as per the burner manual and this
manual.
Burner orientation
For a horizontal installation, you must turn the burner 90o, to the

Blocked Vent Shut-Off (BVSO) for chimney venting
(OPTIONAL)
It is imperative that this device be installed by a
qualified agency.
This device is designed to detect the insufficient evacuation of
combustion gases in the event of a vent blockage. In such a case
the thermal switch will shut down the oil burner. The device will then
need to be re-armed MANUALLY.
In the event that the BVSO repetitively shuts down the oil burner, a
qualified technician needs to evaluate the cause of this shut down.
Refer to the figures 3 to 5 at section 6, Wiring Diagrams and detailed
instructions supplied with the BVSO for the installation and wiring
procedures.
It is also essential that the BVSO be maintained annually.

Duct sizing
Determine airflow CFM
The temperature rise through the furnace must not exceed 85oF and
should be at least 55oF for comfort. When calculating airflow,
assume a temperature rise of 70oF.
The noticeable temperature change for cooling would be
approximately 27-30oF. Actual temperature change will be
approximately 18-21oF due to humidity of the air.
To calculate the noticeable heat temperature change (T), you can
use the formula:
T = BTU/h/(1.1 x CFM) Eq. 3-1
To calculate airflow when you know temperature change (T), you
can use:
CFM = BTU/h/(1.1 x T) Eq. 3-2
You can estimate airflow using the following rules of thumb:
Heating: 14 CFM per 1,000 BTU/h output Eq. 3-3
Cooling: 400 CFM per ton air conditioning Eq. 3-4
Determine the required airflow based on whichever is larger –
heating mode or air conditioning mode.
Examples:
 What would the temperature rise be for a 100,000 BTU/h output
furnace with an airflow rate of 1200 CFM?
Use Equation 3-1 since you know CFM and BTU/h:
T = 100,000/(1.1 x 1200) = 76oF
Thetemperaturerisewouldbe76
oF.
Iftheairentersthefurnaceat70
oF, it would leave the
furnace at 70oF + 76oF = 146oF.
 What would the airflow be to obtain a 70
oF rise through a
120,000 BTU/h output furnace?
Use equation 3-2 since you know T and BTU/h:
CFM = 120,000/(1.1 x 70) = 1,558 CFM
Theairflowwouldhavetobe1,558CFMtoobtaina
temperature rise of 70oF.
 Estimate the required airflow for a 75,000 BTU/h output furnace
installed with a 2-ton air conditioning evaporator coil.
Heating mode airflow (use Equation 3-3):
CFM = 75 x 14 = 1,050 CFM
Cooling mode airflow (use Equation 3-4):
CFM = 2 x 400 = 800 CFM
Thelargernumberis1,050CFM(heating),sotheduct
system should be sized for 1,050 CFM.
Thesupplyductwouldneedtobe16”roundorarectangular
equivalent such as 8” x 25” or 12” x 16”, using Table 4,
page 8.
 Estimate the required airflow for the same furnace installed with
a 4-ton air conditioning evaporator coil.
Heating mode airflow is still 1,050 CFM.
Cooling mode airflow (use Equation 3-4):
CFM = 4 x 400 = 1,600 CFM
Thelargernumberis1,600CFM(cooling),sotheduct
system should be sized for 1,600 CFM.
Thesupplyductwouldneedtobe18”roundorarectangular
equivalent such as 8” x 36” or 12” x 21”, using Table 4,
page 9.
Always check the size of existing ducts, particularly
if you are adding air conditioning. The air pressure
loss through the cooling evaporator coil reduces
available airflow. If the ducts are too small as well,
the system may not work satisfactorily on either
heating or cooling.
Determine duct dimensions
Table 4, page 9, and Table 5, page 10, provide typical round and
rectangular duct sizes for rectangular and flat oval galvanized ducts.
Do not apply these tables to size ductwork if the total equivalent
length of the duct exceeds approximately 100 feet. For longer
systems or for ductboard, fiberglass-lined or flexible duct sizing, use
the ACCA Manual D or the ACCA duct sizing slide rule. These
tables are based on pressure loss of approximately 0.10” water
column per 100 feet equivalent length of duct.
Use Table 3 below to size or check sizing of take-offs to supply
registers or return grills.
Verify the size and type of registers, diffusers and grills from the
manufacturer’s ratings. Do not exceed the recommended flow rate.
The pressure drop allowance for each should not exceed
approximately 0.05” water column.
Install a return air filter, sized per specifications in Section 12.
Use only a return air filter mounted to the furnace. Do not add
additional filters unless the duct system is carefully sized to allow for
the additional pressure drop.

4Venting
General venting requirements
Failure to follow all instructions can result in flue gas
spillage and carbon monoxide emissions, causing
severe personal injury or death.
Inspect existing chimney before installing furnace.
Clean chimney thoroughly. Replace or repair
chimney if visual inspection indicates chimney may
be unsuitable for use. Insufficient draft can cause
flue gas leakage and carbon monoxide emissions.
Failure to clean or replace perforated pipe or tile
lining and/or patch mortar and joints can cause
severe personal injury or death.
 Proper draft for these oil furnaces may be achieved using either
a conventional chimney (natural draft) or a power vent (sidewall)
system that has been properly designed for use with oil-fired
equipment. Power vent manufacturer’s instructions must be
followed.
 Use vent material approved by local codes for oil-fired burners.
In their absence, refer to:
 NFPA 31, Installation of Oil-Burning Equipment.
 NFPA211, Standard for Chimneys, Fireplaces, Vents and
Solid Fuel Burning Appliances.
 In Canada, refer to CSA B139, Installation Code for Oil-
Burning Equipment.
 NFPA-211 requires chimney to be lined before connected to
furnace.
 To prevent downdrafts, extend chimney at least 3 feet above
highest point where it passes through roof and 2 feet higher than
any portion of building within 10 feet. Increase chimney cross-
sectional area and height at least 4% per 1,000 feet above sea
level.
 Provide minimum clearances from vent (flue) pipe to
combustible material:
 Single-wall vent – 18 inches minimum
Type“L”double-wallvent–6inchesminimum
Oversized chimneys, outside masonry chimneys
and/or derated inputs can result in condensation in
chimney.
Connect venting
Long horizontal vent runs, excessive number of tees
and elbows, or other obstructions restricting
combustion gas flow can result in the possibility of
condensation, flue gas leakage and carbon
monoxide emissions, which can lead to severe
personal injury or death.
 The horizontal vent must slope upwards, away from the furnace,
a minimum of ¼inch per foot.
 Connection must be made above bottom of chimney to avoid
blockage. Vent pipe must not enter chimney far enough to cause
obstruction. Use thimble or slip joint where vent pipe enters
chimney to allow removal for cleaning.
 When burner and furnace are properly installed, draft overfire
will be approximately –0.01” to –0.02” w.c. Install barometric
Connect venting (continued)
control in vent, per control manufacturer’s instructions, when
excess draft needs to be relieved or to comply with applicable
codes and regulations. Use draft gauge to adjust proper
opening.
 An induced draft fan for the chimney may be necessary if:
 Excessive resistance to flow of combustion gases can be
expected.
 Cross-sectional area of chimney is smaller than minimum
recommended.
 Chimney height is less than recommended.
 When using induced draft fan seal all vent joints and
interlock burner with fan operation.
Vent dampers
Do not install a thermal-type vent damper on this
furnace. Failure to comply could result in severe
personal injury, death or substantial property
damage.
If a vent damper is required, use only a motorized
one, installed and wired in the furnace according to
the vent damper manufacturer’s instructions.
Barometric draft control
Install a barometric control in the vent, per the manufacturer’s
instructions, when excess draft needs to be relieved or to comply
with applicable codes and regulations. Use draft gauge to adjust
proper opening.
 Install a barometric draft control in the vent pipe at least one foot
from the furnace vent connection, preferably in the highest part
of the vent pipe before the vent enters the chimney. If headroom
does not provide enough clearance to locate the control at least
one foot from the vent connection, install an elbow at the furnace
and mount the control in an horizontal pipe at least one foot from
the elbow. Install an elbow after the control to turn vertically.
 The barometric draft control must be located in the same room
as the furnace to operate correctly.
 Ensure that the barometric draft control is accessible. Adjust the
damper to obtain the correct overfire draft, as described in this
manual and the burner manual.

5Connect fuel oil piping
General oil piping requirements
 Location and installation of oil tanks, oil piping and burners must
follow:
NFPA31,StandardfortheInstallationofOil-Burning
Equipment.
In Canada, CSA B139, Installation of Oil-Burning
Equipment.
 Local codes and regulations.
Informationprovidedwithburnerandfuelpump.
 If any part of the fuel oil tank is above burner level, an anti-
siphon device must be used to prevent the flow of oil in case of
an oil line break.
 Support oil lines as required by codes.
 Make tank connections with swing joints or copper tubing to
prevent breakage in case the tank settles. Make swing joints so
they will tighten as tank settles. Non-hardening pipe joint
compounds should be used on all threads.
Do not use Teflon tape as an oil pipe sealant. It can
cause valves to fail, creating hazards. Use only flare
fittings. Do not use compression fittings. Failure to
comply could result in severe personal injury, death
or substantial property damage from oil leakage
and/or fire hazard.
 Underground pipe must be run in a casing to prevent oil leaking
into the ground or under the floor. Check local codes for
information.
Oil piping connection at burner
 Connect oil line to burner using a flare fitting.
Use of any connection other than a flare fitting at the
oil connection to the burner could result in a fuel oil
leak, with the potential for severe personal injury,
death or substantial property damage.
 See local codes for appropriate arrangement and piping of filter,
control valves, etc. connecting to oil tank.
 Refer to burner manual for oil system requirements. Verify that
suction lift does not exceed stated limit. Where lift exceeds limit
for a one-pipe system, use a two-pipe system as directed in
