IMPROPER INSTALLATION MAY
CREATE A CONDITION WHERE THE
OPERATION OF THE PRODUCT
COULD CAUSE PERSONAL INJURY
OR PROPERTY DAMAGE.
IMPROPER INSTALLATION,
ADJUSTMENT, ALTERATION,
SERVICE OR MAINTENANCE CAN
CAUSE INJURY OR PROPERTY
DAMAGE. REFER TO THIS MANUAL
FOR ASSISTANCE OR ADDITIONAL
INFORMATION, CONSULT A
QUALIFIED INSTALLER, SERVICE
AGENCY OR THE FUEL SUPPLIER.
THIS PRODUCT MUST BE INSTALLED
IN STRICT COMPLIANCE WITH
THESE INSTALLATION
INSTRUCTIONS AND ANY
APPLICABLE LOCAL, STATE, AND
NATIONAL CODES INCLUDING BUT
NOT LIMITED TO: BUILDING,
ELECTRICAL AND MECHANICAL
CODES.
The furnace area must not be used as
a broom closet or for any other
storage purposes, as a fire hazard
may be created. Never store items
such as the following on, near or in
contact with the furnace:
1. Spray or aerosol cans, rags,
brooms, dust mops, vacuum
cleaners or other cleaning tools.
2. Soap powders, bleaches, waxes
or other cleaning compounds;
plastic items or containers,
gasoline, kerosene, cigarette
lighter fluid, dry cleaning fluids,
or other volatile fluids.
3. Paint thinners or other painting
materials and compounds.
4. Paper bags, boxes, or other paper
or cardboard products.
Never operate the furnace with the
blower door removed. To do so could
result in serious personal injury
and/or equipment damage.
DO NOT USE GASOLINE,
CRANKCASE OIL, OR ANY OTHER
OIL CONTAINING GASOLINE AS A
FUEL FOR THIS FURNACE.
INTRODUCTION
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
O4HD-091A
is an oil fired forced
air multi-positional furnace, with an
output capacity range of 58,000 BTU/Hr.
to 79,000 BTU/Hr. Model
O4HD-140A
is
an oil fired forced air multi-positional
furnaces, with output capacity ranges of
87,000 BTU/Hr. to 118,000 BTU/Hr.
These models may be installed in the up-
flow position, as well as both horizontal
positions.
O4HD-091A-12-FA
and
O4HD-140A-16-
FA
are equipped with direct drive
permanent split capacitor motors.
O4HD-091A-V-F
and
O4HD-140A-V-F
are equipped with direct drive ECM
motors.
All models are listed with the
Canadian
Standards Association
, (CSA)
, and
comply with the standards of both the
United States and Canada for use with
No. 1 (Stove) and No. 2 (Furnace) Oil.
In the United States, 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.
HEAT LOSS
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 ductwork. 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,
(ACCA)
, 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 (HRAI)
,
or by other method prescribed by
authorities having jurisdiction that are
suitable for local conditions.
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. Do not install the
furnace on carpet or tiled floors.
Minimum installation clearances are
listed in Table 1.
NOTE
: The recommended installation
clearances do not necessarily take into
consideration the clearances necessary
to replace the air filter or perform other
routine maintenance.
UP-FLOW INSTALLATION
All
O4HD
furnace models have been
assembled for installation in the up-flow
position. Maintain all clearances to
combustibles as outlined in Table 1.
Suggestion
; as a measure to prevent fuel
oil from accumulating in locations other
than the fire pot, as could be the case in
the event of nozzle drip, install the
furnace with an approximate 2 degree
slope from the oil burner casing towards
the fire pot. Use shims made of
noncombustible material.
