2.0 INSTALLATION
2.1
LOCATION
The water heater must be installed on a level and
NON-
COMBUSTIBLE
surface, as close as possible to the
chimney. The water heater must also be located close to a
suitable free-flowing floor drain. Where a floor drain is not
adjacent to the water heater, a suitable drain pan must be
installed under the water heater. This drain pan should be at
least 4’’ (10,2 cm) larger than the diameter of the water heater,
and at least 1’’ (2.5 cm) deep providing access to the drain
valve. This pan must be piped to a suitable drain to prevent
damage to property in the event of a water leak from the
piping, the relief valve, or the water heater.
Sooner or later, all water heaters leak. The manufacturer,
based on national building codes has given the necessary
advice to prevent damage to the building. Under no
circumstances is the manufacturer to be held liable for any
water damage in connection with this water heater.
Note :
If the temperature in the house and/or the
basement is under 16°C (60°F) there is an increased
possibility of condensation inside the chimney.
2.2
ACCESS FOR MAINTENANCE
Convenient access shall be provided to permit cleaning of
heating surfaces, flue pipe and for burner maintenance.
Minimum clearances from combustible material should be:
Table 1 : Minimum clearances
2.3
SHIPPING COMPONENTS
The unit is shipped in two separate cartons; the first carton
is for the water heater tank. The second is for the burner the
aquastat, the wiring harness and the flue adaptor.
2.4
WATER CONNECTIONS
WARNING
To avoid water damage and/or scalding due to relief
valve operation, a discharge line must be connected to
the valve outlet and run to a drainage area. The
discharge line shall be installed in such a way that it will
allow for complete drainage of the valve and discharge
line.
Make the hot and cold water connections to the water
heater. Do not apply heat to the hot water outlet and cold
water inlet, as they contain a plastic sleeve inside. Pressure
relief valves are installed on all models.
2.5
FLUE PIPE
The water heater should be connected to a chimney or an
approved pre-fabricated flue. The flue pipe should be the
same size as the flue outlet of the unit. It is preferable to
maintain a pitch or rise from the heater to the chimney of 2.0
cm per 1 m (1/4" per foot). The flue pipe must not be
extended past the inside wall of the chimney.
2.6
DRAFT REGULATOR
The draft regulator must be installed between the flue outlet
of the water heater and the chimney. (Installation
instructions are furnished with the regulator).
2.7
BLOCKED VENT SHUT-OFF (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 re-armed MANUALLY.
Refer to the wiring diagrams and the detailed instructions
supplied with the BVSO for the installation and wiring
procedure. 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
and paragraph 4.2 of this manual for more details.
2.8
CHIMNEY
For information pertaining to chimney sizes, elevation,
conditions, etc., see C.S.A. Standard B-139, "Installation
code for oil burning equipment."
WARNING
An oil-fired unit shall be connected to a flue having
sufficient draft at all times to assure proper operation of
the unit.
2.9
CONTROLS
Mount the aquastat control on the unit. Set operating control
between 48°C (120°F) and 60°C (140°F). The maximum
setting for all models is 60°C (140°F). If required, set the
high-limit at a temperature of 20 ° F higher than the
operating control.
2.10
WIRING
Connect BX harness from aquastat to the side of the burner
relay junction box. Wire oil burner and controls according to
the attached wiring diagram. The field supplied wiring should
be connected to the top of the aquastat on all models.
