Service Instructions for Your Heating System

Viessmann strongly recommends inspection/service of the
boiler and the system by a licensed professional heating
contractor once a year.
Before the heating season begins, the boiler with its
burner(s) and direct vent system should be serviced by a
qualified heating contractor. Service contracts may be
established through gas suppliers or other licensed
contractors in your area.
Regular inspection/service ensures troublefree, energy-
efficient and environmentally friendly heating activity of
your heating system.
IMPORTANT
If the domestic cold water supply to the hot water storage
tank has a water treatment device (water softener)
installed, ensure its proper working condition is checked
regularly by your heating contractor.
The same applies if a dirt trap or a water filter is installed
in the domestic cold water supply. Any of these devices
installed in the domestic cold water supply must be
flushed out and serviced on a regular basis.
Boiler
All boilers must be cleaned on a regular basis as debris
build-up will result in increased flue gas temperature, and
thus in increased energy consumption.
Notes on operation:
Ensure boiler room and boiler are clean.

Regularly check heating system pressure on the

pressure gauge:
If the needle of pressure gage is below 12 psig, the
system pressure is too low; in this case, please
contact your heating contractor.
Domestic hot water storage tank
Inspection and (if necessary) cleaning of the tank must
take place within 2 years of initial start-up and as required
thereafter.
Cleaning of the inside surfaces of the domestic hot water
storage tank, including domestic hot water connections,
may only be performed by an licensed professional
heating contractor.
Vitocell 100:
Viessmann recommends an annual inspection, and
replacement if required, of the consumable anode by a
licensed professional heating contractor.
The inspection can be carried out during regular operation
of the heating system; shut-down is not required.
The heating contractor measures the protective current
with an anode testing instrument.
Drinking water filter (if installed)
For hygienic reasons
replace filter element every 6 months on filters which

cannot be flushed back, and perform a visual inspection
every 2 months,
flush back reversible flow filters every 2 months.

Please follow manufacturer's instructions.
