Please read these instructions completely and carefully 
before installing and operating the furnace. 
 
The furnace must be installed and set up by a qualified 
contractor 

MODEL 80F 

Model 80F is an oil-fired upflow forced air furnace, with 
an output capacity range of 58,100 BTU/Hr. to 78,900 
BTU/Hr. The 80F furnace equipped with a direct drive 
blower may be installed in both horizontal positions. 

MODEL 120F 

Model 120F is an oil-fired upflow forced air furnace, with 
an output capacity range of 87,700 BTU/Hr. to 113,400 
BTU/Hr. The 120F furnace equipped with a direct drive 
blower may be installed in both horizontal positions. 

NOTE: Furnace models equipped with belt drive blowers 
are not suitable for horizontal applications. 

Both 80F & 120F Model furnaces are listed with the 
Canadian Standards Association, (CSA), complies with 
both Canadian and American (U.S.) standards for use 
with No. 1 (Stove) and No. 2 (Furnace) Oil. Please refer 
to the tables in the appendix for performance and 
dimensional data. 

 

In the United States of America, the installation of the 
furnace and related equipment shall be installed in 
accordance with the regulations of NFPA No. 31, 
Installation of Oil Burning Equipment, as well as in 
accordance with local codes. 

In Canada, the installation of the furnace and related 
equipment shall be installed in accordance with the 
regulations of CAN/CSA - B139, Installation Code For 
Oil Burning Equipment, as well as in accordance with 
local codes.  

When installation or application questions arise, 
regulations prescribed in the National Codes and Local  

Regulations take precedence over the general 
instructions provided with this installation manual. When 
in doubt, please consult your local authorities.  

 

All models are shipped assembled and pre-wired. The 
furnace should be carefully inspected for damage when 
being unpacked. 

 

To determine the correct furnace and firing rate for an 
application, it is necessary to calculate the maximum 
hourly heat loss of the building based on local design 
conditions. In new construction, the heat loss should be 
calculated on a room-by-room basis to enable proper 
sizing of the trunk and branch ducts. In retrofit 
applications, a building shell (overall) heat loss 
calculation may be used. 

In the United States, Manual J. titled, "Load 
Calculation" published by the Air Conditioning 
Contractors of America, describes a suitable procedure 
for calculating the maximum hourly heat loss. 

In Canada, the maximum hourly heat loss may be 
calculated in accordance with the procedures described 
in the manuals of the Heating, Refrigeration and Air 
Conditioning Institute of Canada (HRAI), or by other 
method prescribed by authorities having jurisdiction that 
are suitable for local conditions. 

 

The furnace should be located such that the flue 
connection to the chimney is short, direct and consists of 
as few elbows as possible. When possible, the unit 
should be centralized with respect to the supply and 
return air duct work. A central location minimizes the 
trunk duct sizing. All models may be installed on 
combustible floors. 

Minimum installation clearances are listed in Table 1.
