2.5.4 Side-wall venting
The heating unit is approved for side-wall venting. This system
includes model VTK-65 / VTK-3 / KLAVT0201DET side-wall
venter and a 5” insulated vent pipe, model IFV5xx /
KLAFVxx01DET. Refer to the installation instructions provided
with the venting system.
2.6 BLOCKED VENT SHUT-OFF DEVICE (BVSO)
FOR CHIMNEY VENTING
CAUTION
It is imperative that this device be installed by a qualified
service technician.
A positive pressure venting system (Sealed Combustion
System or Direct Vent)
MUST NOT uses the BVSO. Follow the
instructions supplied with the venting system.
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 re-armed MANUALLY.
Refer to the detailed instructions and wiring diagrams 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 also essential that the BVSO be maintained annually. For
more details refer to the instructions supplied with the device
itself, as well as Section 3 of this Manual.
2.6.1 BVSO Functional Test
The purpose of the following test is only to check that the
electrical outlet on the furnace, designated to the BVSO, is
functional.
1. Start up the burner;
2. Remove the three-pole plug from the BVSO outlet on the
furnace;
3. The burner must shut-off immediately, while the blower
continues to run to the end of the cool-down cycle.
If the test is not in line with the above, call a QUALIFIED
SERVICE TECHNICIAN.
2.7 COMBUSTION AIR SUPPLY
AND VENTILATION
WARNING
Poisonous carbon monoxide gas hazard.
Comply with NFPA 31 (U.S.) and CSA B139 (Canada)
standards for the installation of Oil Burning Equipment
and applicable provisions of local building codes to
provide combustion and ventilation air.
Failure to provide adequate combustion and ventilation
air can result in death, bodily injury and/or property
damage.
Oil furnaces must have an adequate supply of combustion air.
It is common practice to assume that older homes have
sufficient infiltration to accommodate the combustion air
requirement for the furnace. However, home improvements
such as new windows, doors, and weather stripping have
drastically reduced the volume of air infiltration into the
home.
Refer to oil furnace installation codes relative to
combustion and ventilation air requirements. Consult
Section 2.1 in this manual, specifically for units installed
in an enclosed space.
Home air exhausters are common. Bathroom and kitchen
fans, power vented clothes dryers and water heaters all
tend to create a negative pressure condition in the home.
Should this occur the chimney becomes less and less
effective and can easily downdraft. In certain cases,
mechanically supplied air, by way of a blower, interlocked
with the unit, is necessary. It is the installer’s
responsibility to check that.
2.7.1 Contaminated Combustion Air
Installations in certain areas or types of structures will
increase the exposure to chemicals or halogens that may
harm the furnace. These conditions will require that only
outside air be used for combustion.
The following areas or types of structures may contain or
be exposed to certain substances, potentially requiring
outside air for combustion:
a. Commercial buildings;
b. Buildings with indoor pools;
c.
Furnaces installed near chemical storage areas.
Exposure to the following substances:
a. Permanent wave chemicals for hair;
b. Chlorinated waxes and cleaners;
c.
Chlorine based swimming pool chemicals;
d. Water softening chemicals;
e. De-icing salts or chemicals;
f.
Carbon tetrachloride;
g. Halogen type refrigerants;
h. Cleaning solvents (such as perchloroethylene);
i.
Printing inks, paint removers, varnishes, etc. ;
j. Hydrochloric acid;
k. Solvent based glue;
l. Antistatic fabric softeners for clothes dryers;
m. Acid based masonry cleaning materials.
2.7.2 Burner with Outdoor Combustion Air Kit
Certain burners are designed to function with combustion
air taken directly from the outside. Follow the instructions
provided with the burner, the fresh-air supply kit or the
side-wall venting kit.
2.8 OIL TANK
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, bodily injury
and/or property damage.
