Safety
Important Regulatory and Safety Requirements
H Regular maintenance and service
The entire heating system must be cleaned and serviced
on a regular basis by a qualified heating contractor or
service agency to ensure reliable, energy-efficient, and
environmentally friendly operation.
The build-up of soot on the heat exchanger raises the flue
gas temperature and reduces efficiency.
Indirect-fired domestic hot water storage tanks (if
installed) must be serviced within two years (at most) of
the installation date, and regularly thereafter (see Service
Schedule starting on page 10).
For an overview of scheduled service procedures, please
see section entitled "Service Schedule" on page 10 of this
manual.
The owner or dedicated personnel should perform the
checks outlined in the Service Schedule to ensure proper
operation of the heating system.
WARNING
The boiler must not be located in areas or rooms
where chemicals are stored, or aggressive vapors
from (i.e. bleach, hair spray, methyl chloride, carbon
tetrachloride or perchloroethylene) or high dust
levels or humidity levels are present. Heat exchanger
corrosion might occur and reduce the lifetime of the
boiler significantly. If above criteria are not properly
observed and boiler damage results, any warranty
on the complete boiler and related components will
be null and void.
IMPORTANT
Keep boiler and boiler room clear and free from combustible
materials, gasoline and other flammable vapors and liquids.
Do not obstruct the flow of combustion and ventilation air.
All inspection, maintenance and service must be performed
by a qualified heating contractor.

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.
WARNING
As there are no user-serviceable parts on the boiler,
burners or control, the end-user must not perform
service activities of any kind on system components.
Failure to heed this warning can cause property
damage, severe personal injury, or loss of life.
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.
