Maintenance and cleaning

g
Regular inspection and service by a qualified heating
contractor is important to the performance of the
Viessmann CM2 boilers. Neglected maintenance
impacts on warranty; regular inspection ensures
clean, environmentally friendly and efficient operation.
We recommend a maintenance contract with a
qualified heating contractor.

Regular maintenance and service

g
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) should be serviced within two years (at
most) of the installation date, and regularly thereafter.
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.
WARNING
Do not use this boiler if any part has been under, or
exposed to 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, or exposed to, water.
