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.

DANGER OF FREEZING
CAUTION
If your boiler is shut down during the cold weather
season, water pipes may freeze, burst and cause
serious water damage. Turn off the water supply and
bleed the pipes.
If the heater is left unattended during the cold weather
season, take the following precautions:
a.
Close the main water valve in the house and purge the
pipes if possible. Open all the faucets in the house;
b.
Ask someone to frequently check the house during the
cold weather season to make sure that there is sufficient
heat to prevent the pipes from freezing. Tell this person
to call an emergency number if required.
2.5
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 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).
2.5.1
Freeze protection (when required)
WARNING
Only propylene glycol may be used in this hydronic
heating system, to prevent freezing.
It is recommended to add a maximum of 50% of
propylene glycol mixture to ensure proper operation.
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.
Ensure that it is

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.

INSTALLATION OF THE BOILER
At the time of installation, the following steps should be
followed. Refer to Figures 3 and 4 for additional information.
Choose an appropriate location.

ELECTRIC POWER SUPPLY
All electrical wiring must conform to the standards and
regulations in force and the Canadian Electrical Code CSA
C22.1.
Electrical power to the boiler must come from a 120/240V 60
