Important Regulatory and Installation Requirements
Codes
The installation of indirect-fired hot
water storage tanks might be governed
by individual local rules and regulations
for this ty e of roduct, which must be
observed. Always use latest editions of
codes.
Mechanical room
Ensure the mechanical room com lies
with the requirements of the technical
data manual.
The tank must be installed in a
mechanical room which is never subject
to freezing tem eratures.
If not in use and danger of freezing
exists in the mechanical room, ensure
water in tank is drained.
Please carefully read this manual prior
to attempting installation. Any
warranty is null and void if these
instructions are not followed.
his product must be installed
observing not only the necessary
product literature (see list below), but
also all local, provincial/state
plumbing and building codes, as they
apply to this product and all periphery
equipment.
For information regarding other
Viessmann System echnology
componentry, please reference
documentation of the respective
product.
We offer frequent installation and
service seminars to familiarize our
partners with our products. Please
inquire.
Working on the equipment
The installation, adjustment, service,
and maintenance of this equi ment
must be done by a licensed professional
heating contractor who is qualified and
ex erienced in the installation, service,
and maintenance of hot water heating
systems. There are no user serviceable
arts on this equi ment.
Ensure main power su ly to
equi ment, the heating system, and all
external controls has been deactivated.
Close main oil or gas supply valve. Take
recautions in all instances to avoid
accidental activation of ower during
service work.
he completeness and functionality of
field supplied electrical controls and
components must be verified by the
heating contractor. hese include low
water cut-offs, flow switches (if used),
staging controls, pumps, motorized
valves, air vents, thermostats,
temperature controls, etc.
Technical literature
Literature a licable to all as ects of
the Vitocell:
- Technical Data Manual
- Installation Instructions
- Start-u /Service Instructions
- O erating Instructions
and User’s Information Manual
Leave all literature at the installation
site and advise the system
operator/ultimate owner where the
literature can be found. Contact
Viessmann for additional copies.
5167 519 v2.2
If the heating system itself is to be
filled with Glycol or any other
antifreeze, the system fill must be of
non-toxic or food grade antifreeze. In
any circumstance, a non-toxic fluid
must be used. Ensure a copy of the
Material Safety Data Sheet (MSDS) is
supplied to the operator/ultimate
owner of the system.

mounted on the tank.
HPosition tank carefully and remove

Multiple Tank Set-up only for 79 and 120 USG / 300 and 450 ltr capacity
Two tanks, each with 79 USG / 300 ltr content, or up to four tanks, each with 120
USG / 450 ltr content, may be installed side-by-side.
he tank battery is controlled via one DHW tank aquastat making control of
individual tanks within the tank battery impossible.
If control of individual tanks within a battery is necessary, two alternatives exist.
Either a 4-tank battery needs to be separated into smaller batteries i.e. two
batteries each consisting of two tanks (one DHW tank aquastat controls each
battery), or all tanks should be installed individually i.e. individual tank set-up (one
DHW tank aquastat controls each tank).
