WARNING
Fire and explosion hazard.
Use only approved heating type oil in this
furnace. DO NOT USE waste oil, used motor oil,
gasoline or kerosene.
Use of these will result in death, personal injury
and/or property damage.
NOTE
: You may notice a slight odour the first time
your furnace is operated. This will soon disappear.
It is only the oil used on certain parts during
manufacturing.
1.8
BLOCKED VENT SHUT-OFF DEVICE
(BVSO) For chimney venting
WARNING
It is imperative that this device be installed by
a qualified technician.
This device is designed to detect the insufficient
evacuation of combustion gases in the event of a vent
blockage. In such a case the thermal switch will shut
down the oil burner. The device will then need to be
restarted MANUALLY.
Refer to the wiring diagrams and the detailed
instructions supplied with the BVSO for the installation
and wiring procedures. The length of wires supplied with
the unit is such that the safety device must be installed
between the flue outlet of the appliance and the draft
regulator, as indicated in the instructions.
It is further imperative that the BVSO be maintained
annually. Refer to the instructions supplied with the
device itself, as well as Section 3. of this Manual.
CAUTION
Do NOT use the BVSO on a positive pressure
venting system (Sealed Combustion System or
Direct Vent). Follow the instructions supplied with
the venting system.
1.9 INSTALLING
ACCESSORIES
WARNING
Electrical shock hazard.
Turn OFF electric power at fuse box or service
panel before making any electrical connections
and ensure a proper ground connection is made
before connecting line voltage.
Failure to do so could result in death, bodily
injury and/or property damage.
1.9.1
Electronic air cleaner
Wire terminals are provided to direct 115 volts @ 0.5 Amp
maximum to an Electronic Air Cleaner (EAC). Power will be
available to the EAC at all times, so it must incorporate a flow
proving switch if it is to be wired into the furnace control box. Most
modern EACs have the required integral airflow proving switch.
Wire the electronic air cleaner between terminals #5 and #2. Refer
to wiring diagram, Figure 6.
1.9.2 Humidifier
The red wire from burner can be used to direct 115 volts @ 1.0
Amp maximum to the transformer powering the humidifier. The
humidifier will be energised anytime the burner is operating in the
“Heating Mode”. Refer to wiring diagram, Figure 6.
1.9.3 Air
conditioning
An air conditioning coil may be installed on the supply air side only.
Also, notwithstanding the evaporator coil manufacturer’s
instructions, a minimum of 15 cm (6") clearance must be allowed
between the bottom of the coil drain pan and the top of the heat
exchanger. Wire the thermostat and condensing unit contactor as
indicated in Figure 6
.
1.9.4
Ductwork and Filter
Installation
Design and install the air distribution system to comply with Air
Conditioning Contractors of America manuals or other approved
methods that conform to local and/or national codes and good
trade practices.
When furnace supply ducts carry air outside furnace area, seal
return air duct to furnace casing and terminate duct outside furnace
space.
Install air conditioning cooling coil (evaporator) on downstream
side from the supply air plenum of the furnace. If a separate
evaporator and blower unit is used, install appropriate sealing
dampers for air flow control. Cold air from the evaporator coil going
through the furnace could cause condensation and shorten furnace
life.
CAUTION
Dampers (purchased locally) MUST be automatic.
WARNING
Poisonous carbon monoxide gas hazard.
Do NOT draw return air from inside a closet or utility
room. Return air duct MUST be sealed to furnace
casing.
Failure to properly seal duct can result in death,
personal injury and/or property damage.
