REFERENCE
1.
INTRODUCTION
Please
read
these
instructions
completely
and
carefully before installing and operating the furnace.
MODELS
O4LD-091A-12-RA
AND
O4LD-091A-
14-RA-DV
Models O4LD-091A-12-RA and O4LD-091A-14-RA-DV
are oil fired forced air up-flow furnaces with an output
capacity range of 59,500 BTU/Hr. to 87,000 BTU/Hr.
ACAUTION
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
shail
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.
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.
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.
3. LOCATION OF UNIT
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.
The
minimum
installation clearances are listed in Table
1.

4. AIR CONDITIONING APPLICATIONS
lf
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.
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
