Prepare furnace and place in position
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.

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 ¼ inch 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 90
o
, to the
normal orientation. Always keep the motor shaft in horizontal
position.
