Design information

Installation for balanced flue operation
The Vitopend is a boiler type B , B
22
C , C , C or C to TRGI '86/96.
52 62 82 82x
& The Vitopend can be installed for balanced flue operation inde-
pendent of the size and ventilation of the boiler room.
& It may, for example, be installed in rooms with personnel traffic
or in accommodation rooms, in ancillary rooms without ventila-
tion, in cupboards and recesses without maintaining minimum
clearances to combustible components as well as in attic rooms
(pitched attics and ancillary rooms) where the balanced flue
pipe can be directly routed through the roof.
Installation for open flue operation
As equipment of type B is being installed, the boiler room is
11BS
subject to the following requirements to TRGI '86/96:
&
Avoid air contamination through halogenated hydrocarbons (e.
g. as in sprays, paints, solvents and cleaning agents)
& Avoid very dusty conditions
& Avoid high levels of humidity
& Protect against frost and ensure good ventilation
& Provide a drain in the boiler room for the blow-off line of the
safety valve.
& The maximum ambient temperature of the system should not
exceed 45 °C.
&
Secure the Vitopend near the chimney stack/duct.
&
In rooms where air contamination from halogenated hydrocar-
bons is to be expected, operate the boiler only in balanced flue
mode.
If these instructions are not observed, any consequential losses
directly related to any of these causes are excluded from our war-
ranty.

Permissible:
&
Boiler installation on the same floor
&
Living space with interconnected room ventilation
& Adjacent rooms with interconnected room ventilation (larders,
basement, utility rooms, etc.)
& Adjacent rooms with apertures to the outside (ventilation air/
