Delivery, Handling And Siting - Viessmann VITOCROSSAL 200 Type CM2 Technical Manual

Design information

8.1 Delivery, handling and siting

Delivery
We deliver the equipment to site on a vehicle with crane and will unload
the equipment, subject to there being no special hindrance.
Handling and siting
A sufficient number of lifting eyes is provided on each boiler, to which
lifting gear may be attached.
Vitocrossal 300, type CT3B, with 187 to 635 kW can be delivered in
sections upon request. The front part of the combustion chamber can
then be removed for easier handling (chargeable option; please state
when ordering).
The Vitocrossal 300, type CR3B boilers can be supplied with a split
combustion chamber and heat exchanger for individual handling. The
linear base rails simplify handling. Our experts can undertake the han-
dling and siting on prepared foundations upon request (chargeable
option).
Installation location
General requirements
The installation room must meet the standards laid down by the Fire
Regulations of the respective country. In rooms where air contamina-
tion through halogenated hydrocarbons may occur, such as hairdress-
ing salons, printing shops, chemical cleaners, laboratories etc., the
boiler may only be installed if adequate measures can be taken to
provide a supply of uncontaminated combustion air. If in doubt, please
contact us.
Boilers should not be installed in areas subject to dusty or very humid
conditions. The installation room must be kept free from frost and must
be adequately ventilated. If these instructions are not observed, any
consequential boiler damage directly related to any of these causes is
excluded from our warranty. These boilers are particularly suitable for
installation in attics. They require no high chimneys as they are oper-
ated with a pressurised combustion chamber.
Requirements of the Muster-Feuerungsverordnung [Sample
Combustion Ordinance - Germany]
Requirements for installation rooms are listed in the "Sample Com-
bustion Ordinance". The Building Regulations of each country apply.
Combustion air supply
For open flue combustion equipment with a total rated heating output
in excess of 50 kW, the combustion air supply is deemed to have been
verified if the combustion equipment is located in rooms that provide
an aperture or duct leading outdoors. The cross-section of the aperture
2
must be at least 150 cm and must be 2 cm
kW above 50 kW rated heating output. Pipes must be sized to provide
equivalent flow rates. The required cross-section may be split over a
maximum of 2 apertures or pipes.
A
Gas condensing boilers
The boilers may be placed onto concrete without special foundations.
However, to facilitate cleaning of the boiler room it is advisable to posi-
tion the boiler on a plinth.
For recommended minimum wall clearances for installation and main-
tenance work, see the datasheet of the respective boiler.
Anti-vibration boiler supports may be used if structure-borne noise
attenuation is required.

Combustion air apertures and pipes must not be closed or blocked if
installed safety equipment cannot adequately ensure that the com-
bustion equipment can only be operated when the aperture is open.
The required cross-section must not be blocked by any closure or
grille. An adequate combustion air supply can also be assured by other
means.
Installation locations for combustion equipment
Only install combustion equipment for gaseous or liquid fuels with a
total rated heating output in excess of 50 kW in areas meeting the
following conditions:
■ Not used for other purposes, except the installation of heat pumps,
■ No openings leading to other rooms, except doorways
■ Doors tight and self-closing
■ Ventilation facility
The burner and the fuel supply of the combustion equipment must be
able to be shut down at any time by an emergency stop switch installed
outside the installation room. Provide a sign adjacent to the emergency
stop switch that reads "EMERGENCY STOP SWITCH – COMBUS-
TION".
