Operation
Before operating the boiler, make sure you fully
understand its method of operation. Your heating
contractor should always perform the initial start-up
and explain the system. Any warranty is null and void if
these instructions are not followed.
DANGER
What to do if you smell flue gas
•
Ensure all people are evacuated from the house
immediately
•
Deactivate heating equipment.
•
Open windows and doors.
•
Do not try to light any appliances.
•
Do not touch any electrical switches, do not use
any phone in your building.
•
Immediately call your heating contractor or gas
supplier from a neighbour's phone. Follow the gas
supplier's instructions.
•
If you cannot reach your gas supplier, call the fire
department.
Working on the equipment
All personnel working on the equipment or the heating
system must have the proper qualifications and hold all
necessary licenses.
Ensure main power to equipment, heating system, and
all external controls has been deactivated. Close main
gas supply valve. Take precautions in all instances to
avoid accidental activation of power during service
work.
Dangerous conditions
• Deactivate main power immediately.
• Close gas supply valve.
CAUTION
Incomplete combustion and poisonous gases result
if the fresh air intakes in the mechanical room are
closed. Never close these openings.
Maintenance and cleaning
Regular inspection and service by a qualified heating
contractor is critical to the performance of the boiler.
Neglected maintenance impacts the warranty;
regular cleaning and maintenance ensures clean,
environmentally friendly and efficient operation. We
recommend a maintenance contract with a qualified
heating contractor.
For safe operation
We recommend that you frequently:
- Check for debris which could obstruct the flow of flue
gases. The vent or chimney must not be blocked.

Safety Information
A blocked or partially blocked vent or chimney can
cause flue gases to leak into the structure. Flue gases
leaking into the house can cause injury or death.
Blocked or partially blocked chimneys must have the
blockage removed by a qualified heating contractor. Check
pressure gauge for correct system (water) pressure.
- Check for water on the floor from the discharge pipe
of the pressure relief valve or any other pipe, pipe
joint, valve or air vent.
- Check for moisture, water, or appearance of rust
on the flue gas pipes, their joints as well as vent
dampers, or side wall vent terminals (if so equipped).
- Ensure that nothing is obstructing the flow of
combustion and ventilation air and no chemicals,
propane tanks, garbage, gasoline, combustible
materials, flammable vapours and liquids are stored
(not even temporarily) in the vicinity of the boiler.
- Do not allow unsupervised children near the boiler.
- Service/inspection of the boiler and the system must
be serviced yearly. Maintenance, service and cleaning
are specified in the Installation Instructions.
- Before the heating season begins, the boiler must be
serviced by a qualified heating contractor.
• There are no user serviceable parts on the boiler,
burners or control. Failure to heed this warning can
cause property damage, severe personal injury, or
loss of life.
• Improper installation, adjustment, service, or
maintenance can cause flue products to flow into
living space. Flue products contain poisonous
carbon monoxide gas which can cause nausea or
asphyxiation resulting in severe personal injury or
loss of life.
• Should overheating occur or the gas supply fail to
shut off, do not disconnect the electrical supply to the
pump. Instead, shut off the gas supply at a location
external to the appliance.
Do not use this boiler if any part has been under water.
Immediately call a qualified heating contractor to inspect
the boiler and to replace any part of the control system
and any gas control which has been under water.
Do not store chemicals containing chlorine or other
corrosive materials near the boiler, such as bleach,
cleaning solvents, detergents, acids, hair spray, spray
cans, paint thinners, paint, or water softener salt.
