How to realize the flue gas exhaust
In case of flue gas discharge in correspondence of the boil-
er, connect to the flue gas connection provided on the upper
part of the casing the special rainproof terminal, available as an
option (code OTRM031 for Caldaria 35 and Caldaria 55.1, code
OTRM009 for Caldaria 100.2).
It is not recommended to install the flue terminal near
the boiler if it is close to a wall. This condition could cause
condensation to form on the terminal and on the wall
that would fall on the boiler.
To avoid this type of problem, it is recommended to
take the flue terminal beyond the roof of the building
as shown in Figure 3.12 p. 26 or to carry out the flue
exhaust horizontally as shown in Figure 3.13 p. 26, re-
specting the indications given in Paragraph 3.4.3 p. 26.

Possible flue
In case of extension of the duct, follow the instructions below:
▶
Use ducts and terminals suitable for forced draft condensing
appliances.
▶
The residual head is detailed in Table 3.3 p. 27.
▶
The horizontal sections for flue gas exhaust must always be
mounted on a slope towards the appliance (3° slope = 5 mm
per metre of pipe). In this case, check that any condensation
residues coming from the terminal do not fall on objects or
material that could be damaged.
▶
For vertical ducts longer than 1,5 m, a curve and a Tee (Figure
3.14 p. 26) for condensate collection and drainage must
be provided. The condensate must then be evacuated in ac-
cordance with the regulations in force, at the same time as
that coming from inside the boiler.
