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.
