When connecting several boilers to
the same duct (i.e. types C43, C83
or cascades), make sure to install
an AIC-approved flue gas damper
on each boiler in the system.

If required by local regulations, install a
condensate neutralisation system. In that
case, it may be necessary to install the
floor-standing boiler on a base to get suf-
ficient downward flow. If flow is not suffi-
cient, install a condensate pump.

Description
C
43
Appliance connected via its two ducts to a common duct system (part of the building) designed for
more than one appliance. The common duct system consists of two ducts connected to a terminal,
which at the same time admits fresh air to the burner and discharges the products of combustion to
the outside through orifi ces that are either concentric or close enough to come under similar wind
conditions.
Additional requirements:
• Connection to a chimney with natural draught only.
• Condensate fl ow is not allowed into the appliance.
C
53
Appliance with separate ducts for the supply of combustion air and the discharge of fl ue gas. The
air inlet and fl ue exhaust are located in diff erent pressure areas, but not on opposite walls of the
building.
C
83
Appliance connected through one of its ducts to a single or common duct system (part of the build-
ing). The combustion air is taken from the outside, and the fl ue discharge duct is routed through
the chimney to the roof.
Additional requirement:
• Condensate fl ow is not allowed into the appliance.
