Service Instructions For Your Heating System - Viessmann Vitotronic 100 HC1 User's Manual And Operating Instructions

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 trouble-free, energy-efficient and
environmentally friendly heating activity of your heating system.
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.
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
DHW storage tank, including DHW
connections, may only be performed by
a 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 tester.
Drinking water filter (if installed)
For hygienic reasons
H replace filter element every
6 months on filters which cannot be
flushed back, and perform a visual
inspection every 2 months,
H flush back reversible flow filters
every 2 months.
Safety valve (DHW tank)
The safety valve function should be
checked every six months by venting,
either by the system user or the local
heating contractor. The valve seat may
become contaminated.
Service Instructions
Notes on operation:
H Ensure boiler room and boiler
are clean.
H Regularly check heating system
pressure on the pressure gage:
If the needle of pressure gage is
below 12 psig, the system pressure
is too low; in this case, please
contact your heating contractor.
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.
