WATER CONNECTIONS
CAUTION
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 models CM-32,
CMO32 and CMO50.

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.

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
