Safety
For Your Safety
H 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.
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 loss of life.
Blocked or partially blocked chimneys must have the
blockage removed by a qualified heating contractor.
- Check pressure gage 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,
garbage, gasoline, combustible materials, flammable
vapors 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 is
recommended once a year.
Maintenance, service and cleaning are specified in the
Installation Instructions.
Before the heating season begins, it is recommended that
the boiler and burner be serviced by a qualified heating
contractor. Service contracts may be established through
gas suppliers or other licensed contractors in your area.

WARNING
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.
CAUTION
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.
WARNING
The operator/ultimate owner is required to have the
heating boiler, burners, and controls checked, as a
minimum once per year, by the original installer or
by a competent heating contractor familiar with the
equipment. Defects must be corrected immediately.
CAUTION
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.
WARNING
As there are no user-serviceable parts on the boiler,
burner or control, the end-user must not perform
service activities or adjustments of any kind on system
components. Failure to heed this warning can cause
property damage, severe personal injury, or loss of life.
