FLUE EXHAUST
The smoke duct and the connection to the chimney must be built in compliance with the Standards and the Laws in force, with
rigid pipes, suitable for the temperature, resistant to condensate, mechanical stresses and sealed.
m
IMPORTANT
The smoke duct must have a diameter equal to or larger than the Boiler fitting.

DANGER
–
the chimney must ensure the draught necessary for the Boiler operation and provided by the Technical Standards in
force, considering a “zero” pressure at the connection with the smoke duct
–
unsuitable or badly dimensioned chimneys and smoke ducts can cause problems and adversely affect the combustion
parameters
–
non-insulated drain pipes can lead to a potential risk and the tightness of the joints must be ensured with materials
resistant to the temperatures of the drain flue gases (we recommend at least 250°C)
–
check that the chimney has an adequate draught and that is free from bottlenecks and waste.
CONDENSATE DRAIN
MONOLITE GT
Boilers are equipped with a condensate drain pipe, derived from the appliance and the flue gas drain.
The condensate is acid and
MUST
be treated, by the installer, in compliance with the national and local Laws in force in the
country of installation.
The condensate acidity can be periodically checked using litmus test paper to determine the pH.
For the choice of the condensate neutraliser, which is system ACCESSORY to be ordered and purchased separately, use the ICI
catalogue.
m
IMPORTANT
–
The condensate drain pipe must be sealed and have dimensions ≥ than those of the appliance drain pipe and of the trap
and it must not have bottlenecks and reductions.
–
It is recommended that it always has a slope ≥ than 3% towards the drain.
