1.  INTRODUCTION

 

Please read these instructions completely and 
carefully before installing and operating the furnace. 

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 ductwork. A central location minimizes the 
trunk duct sizing. All models may be installed on 
combustible floors. 

MODELS O5LD-091A-12-R 

 

Model O5LD-091A-12-R is an oil fired forced air up-
flow furnace with an output capacity range of 59,000 
BTU/Hr. to 85,000 BTU/Hr. 

The minimum installation clearances are listed in Table 
1.

 

Table 1:  Clearances – (Inches)

 

 

DO NOT USE GASOLINE, CRANK CASE OIL, 
OR ANY OIL CONTAINING GASOLINE.

 

All models are CSA listed, (NRTL/C) for use with No. 1 
(Stove) and No. 2 (Furnace) Oil. Please refer to the 
tables in Appendix A for performance and dimensional 
data. 

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.  

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, 

Standard for the Installation of Oil-Burning Equipment

as well as in accordance with local codes. 

Regulations prescribed in the National Codes and 
Local regulations take precedence over the general 
instructions provided on this installation manual. When 
in doubt, please consult your local authorities.

4.  AIR CONDITIONING APPLICATIONS 

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

 

2.  HEAT LOSS 

The maximum hourly heat loss for each heated space 
shall 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 means prescribed, or approved by the local 
authority having jurisdiction. 

If the furnace is used in conjunction with air 
conditioning, the furnace shall be installed in parallel 
with or upstream from the evaporator coil to avoid 
condensation in the heat exchanger. In a parallel 
installation, the dampers or air controlling means must 
prevent chilled air from entering the furnace. If the 
dampers are manually operated, there must be a 
means of control to prevent the operation of either 
system unless the dampers are in the full heat or full 
cool position. The air heated by the furnace shall not 
pass through a refrigeration unit unless the unit is 
specifically approved for such service. 

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. 

The blower speed must be checked and adjusted to 
compensate for the pressure drop caused by the 
evaporator coil. Refer to Appendix B for recommended 
wiring and electrical connections of the air conditioning 
controls.
