Positioning The Furnace; Installation In An Enclosure; Configurations; Upflow Installation - Bryant OVM098 Installation Instructions Manual

The unit is shipped with a burner and its controls. It requires a 115VAC
power supply to the control panel and thermostat hook-up as shown on
the wiring diagram, one or more oil line connections, suitable ductwork
and connection to a properly sized vent.
All local and national code requirements governing the installation of oil
burning equipment, wiring and the flue connection MUST be followed.
Some of the codes that may apply are:
CSA B139: Installation code for oil burning equipment;
ANSI/NFPA 31: Installation of oil burning equipment;
ANSI/NFPA 90B: Warm air heating and air conditioning systems;
ANSI/NFPA 211: Chimneys, Fireplaces, Vents and solid fuel
burning appliances;
ANSI/NFPA 70: National Electrical Code;
CSA C22.1 : Canadian Electrical Code;
or CSA C22.10
Only the latest issues of these codes shall be used.

2.1 POSITIONING THE FURNACE

WARNING
F
IRE AND EXPLOSION HAZARD
The furnace must be installed in a level position, never where
it will slope toward the front.
Do not store or use gasoline or any other flammable
substances near the furnace.
Non-observance of these instructions will potentially result in
death, bodily injury and/or property damage.
CAUTION
This furnace is not watertight and is not designed for outdoor
installation. It must be installed in such a manner as to protect
its electrical components from water. Outdoor installation will lead
to a hazardous electrical condition and to premature failure of the
equipment.
The minimum clearances from combustible material for each of
the positions are specified in Table 9.
If the furnace is installed in a basement or on a dirt floor, in a crawl
space for example, it is recommended to install the unit on a cement
base 2.5 cm to 5.0 cm (1" to 2") thick.
The unit must be installed in an area where the ambient and return air
temperatures are above 15°C (60°F). In addition, the furnace should
be installed as closely as possible to the vent, so that the connections
are direct and kept to a minimum. The heater should also be located
close to the centre of the air distribution system.

2.1.1 Installation in an enclosure

The unit can be installed in an enclosure such as a closet. However,
two ventilation openings are required for combustion air. The openings
should be located in front of the furnace approximately 15 cm (6")
above the floor and 15 cm (6") below the ceiling. Figure 1 indicates the
minimum dimensions required and the location of the openings.

openings in a closet door

2.2 CONFIGURATIONS

2.2.1 Upflow installation
The return air opening may be located on either side of the furnace.
Care should be taken not to damage the wires inside, while cutting
the opening. Install the filter rack supplied with the unit according to
the instructions provided with it. It is also recommended to install the
blower door before handling or moving the unit. Refer to Figure 2 for
additional details.
Figure 2 – Upflow Installation
2.2.2 Downflow Installation
When the furnace is installed in the downflow position on a combustible
floor, the clearances from combustibles must be adhered to.
downflow base DFB-102 or KLASB0801DET can be used to ensure
these clearances. Refer to Figure 3 and the installation instructions
provided with the base.
In cases where the return air enters through the floor, the floor return
base FRB-101 or KLARB0101DET must be used.
The burner must always be installed in the same manner, regardless of
the discharge position of the furnace. Refer to Figure 3 for additional
details.
The protection plate (B03789) must be installed on the plastic
cover of the Beckett NX burner to protect it from vent. ONLY the
