INSTALLATION
WARNING
The installation of this unit must be performed by
a qualified technician and it must conform to the
standards and regulations in force as well as the
Canadian Installation Code for Hydronic Heating
Systems CSA B214-01.
1.6.1) Positioning and clearances
The unit must be installed in an area that is dry, non-
corrosive, without excessive dust, well ventilated and where
the ambient temperature does not exceed 27°C (80°F).
The boiler can be installed directly on a wall, by way of the
mounting plate, supplied with the unit.

DISTRIBUTION SYSTEM
The proper functioning of your heating system is directly
related to the quality of the plumbing installation. Therefore,
the entire installation must be performed by qualified
technicians.
See Figure 3, p. 11 for the functions of the various boiler
connections.
The heating system must be set-up to operate at a maximum
pressure of 28 psi and the operating temperature may range
from 32˚C to 99°C (90˚F to 210°F).

Do not use automotive anti-freeze, ethylene glycol
or any undiluted anti-freeze.
If the above recommendations are not followed,
severe personal injury, death or substantial
property and/or equipment damage can result.
All installations must include the following items:
a.
1 pressure regulator, adjusted to 12 psi, installed
between the boiler and the main water supply in the
building;
b.
1 expansion tank, pre-pressurized to 12 psi and of
appropriate size;
c.
1 or more automatic air purge valves;
d.
1 or more circulating pumps of appropriate capacity.
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.
discharge line shall be installed in such a way that it
will allow for the complete drainage of the valve and
the discharge line.
