Storage Of Vitomax Boilers Prior To Installation As Part Of The System - Viessmann VITOMAX 200-HS M73A Installation Instructions Manual

Storage of Vitomax boilers prior to installation as part of the system

Please note:
This information applies to the storage prior to the system installation.
1. Vitomax boilers must be stored in
enclosed rooms, free from weather
influences under dry conditions.
2. The room temperature must not fall
below 0 °C nor exceed +50 °C.
3. In its delivered condition the boiler is
protected as standard on the water
side with dummy flanges or caps
against the ingress of foreign matter.
4. Remove the shipping packaging to
prevent the formation of condensate.
To prevent corrosion in the non-pressur-
ised state, observe the following if the
boiler is stored for longer than 4 weeks:
■ Protect the interior of the boiler against
moisture on the flue gas side and on
the DHW side with a desiccant, e.g.
silica gel.
■ The amount of desiccant depends on
the boiler volume.
4
■ Check the effectiveness of the desic-
cant regularly. See the details provi-
ded by the desiccant manufacturer.
■ Ensure that the desiccant does not
come into contact with the boiler mate-
rial (e.g. through suspended fixing).
■ Preserve the dry flue gas side with a
thin film of graphite or boiled oil.
■ Instead of the moisture extraction on
the flue gas side by means of a desic-
cant; a dryer with air circulation can
also be connected.
