IMPORTANT
Ensure that the lifting/handling equipment is able to
securely handle the size and weight of this tank
(see data on page 2).
The floor where the tank is to be positioned must be able
to properly support the weight of the tank filled with water.
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.
Refer to the Installation and Start-up/Service
Instructions applicable to this boiler.
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.
Product Information
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.

Technical information subject to change without notice. Printed on environmentally friendly
(recycled and recyclable) paper.
PRV Installation
Note: The pressure relief valve/air vent is normally
installed to the top opening of the tank (as shown).
If height is a concern, the pressure relief valve can
be installed to the flanged supply connection to the
heating system or from the biomass boiler (see N2/
N4 on page 2) using a field supplied fitting.
Ensure that the pressure relief valve spindle is
always installed vertically. The air vent must be
installed at the top of the tank.
The discharge line opening of the pressure relief
valve must be piped 1.0 ft. (300 mm) above the
floor close to the floor drain with copper or steel
pipe. The discharge pipe must be installed in the
shortest distance and pitch downward from the
pressure relief valve and terminate plain. Ensure
the pressure relief valve is adequately secured.
WARNING
The discharge pipe for the pressure relief valve must be
oriented to prevent scalding of attendants.
Never pipe the discharge pipe to the outdoors.
WARNING
Do not install an isolation valve or any kind of an
obstruction between the tank and the pressure relief
valve or between the pressure relief valve and the
discharge pipe outlet.
Wall Clearances
Note: Dimensions shown are recommended minimum
service clearances. IMPORTANT
The final location/position of the tank inside the building/
structure must allow access to the manway opening for
tank inspection. If the tank is tight to the wall, an opening
in the wall/structure must be provided to properly access
the manway opening.
The tank rating plate must be in an accessible location.
