Vitorond 200, VD2A Series Installation
Connections
CAUTION
The Vitorond 200, VD2A boiler is not approved for side
wall venting.
Chimney
For proper operation of the Vitorond 200, VD2A boiler,
all products of combustion must be safely vented to
the outdoors, while ensuring that flue gases do not cool
prematurely.
It is critical that the chimney system be properly designed
to handle the relatively cool flue gas temperatures
produced by the Vitorond 200, VD2A boiler.
If the chimney system lacks sufficient insulation and/or
the chimney diameter is too large, corrosive and damaging
condensation will result due to flue gases cooling too
quickly. If a calculated chimney diameter lies between
two values, the larger diameter should be selected.
The chimney connection length between the boiler vent
pipe collar and the chimney must be installed with
insulation.
Vent pipe collar diameter does not automatically
indicate vent/chimney size.
We recommend consulting a reputable chimney installer
for advice in project-specific circumstances.
When installing the Vitorond 200, VD2A boiler,
it is necessary to install a barometric draft regulator
in the chimney/vent for proper operation of the boiler.
Install the barometric draft regulator within 5 to 7 ft.
(1½ to 2 m) from the breeching outlet located at the
rear of the boiler.

WARNING
When installing or insulating (overhead) piping

Advise other trades accordingly!
Never operate boiler without an installed venting system
which safely vents all products of combustion to the
outdoors.
The vent system must comply with all applicable local
and/or national codes.
Vitorond 200, VD2A boilers are Category I and III boilers
