2  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.
