Safety and Installation Requirements

Please ensure that these instructions are read and
understood before starting any service work. Failure
to comply with these instructions may cause product/
property damage, severe personal injury and/or loss of
life.

Working on the equipment

The installation, adjustment, service and maintenance of
this product must be performed by a licensed professional
heating contractor who is qualified and experienced in the
installation, service, and maintenance of hot water boilers.
There are no user serviceable parts on the tanks.

Product Information

Ensure that main power to the equipment being serviced
is off.

Take precautions to avoid accidental activation of power
during service work.

Do not perform service work on any component part
without ensuring safe operation of the heating system.
When replacing parts, use original Viessmann or
Viessmann approved replacement parts.

Refer to the Installation and Start-up/Service
Instructions applicable to this boiler.

ASME ‘U’ code symbol stamped, pressure vessel with
a Canadian Registration Number (CRN). When used in
conjunction with Biomass boilers, the Biomass Thermal
Storage Tank acts as a thermal reservoir and as a
hydraulic break, decoupling boiler and the heating circuit
from each other.

Heat may be added to the tank by the biomass boiler
or back-up systems and removed by the distribution
system at different rates. This ensures steady supply
temperatures to the heating system and ensures efficient
energy use.

The tanks are equipped with three or five temperature
sensors connected to the boiler control to regulate the
biomass boiler operation.
