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

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
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
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.
Local
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
be
the fire pot. Use shims made of
noncombustible material.
