Baffles
Boiler operation requires fitting the baffles supplied with the unit, according to that given
in the following tables.
Before inserting the fume exhaust pipe, check the presence of the right baffle (when it is to
be used) and that it is correctly positioned. The boilers are fitted standard with the smallest
diameter baffle. To replace the baffle (ref. 1 - fig. 10), proceed as indicated in fig. 10.

For coaxial connection, fit the unit with one of the following starting accessories. For the
wall hole dimensions, refer to the figure on the cover. Anyhorizontal sections of the fume
exhaust must be kept slopingslightly towards the outside, to prevent possible conden-
sate from flowing back towards the unit.

Before proceeding with installation, check the baffle to be used and make sure the max-
imum permissible length has not been exceeded, by means of a simple calculation:
1.
Completely establish the layout of the system of split flues, including accessories
and outlet terminals.
2.
Consult the table 4 and identify the losses in m
eq
(equivalent metres) of every com-
ponent, according to the installation position.
3.
Check that the sum total of losses is less than or equal to the maximum permissible
length in table 3.

3.7 Condensate drain connection
The boiler is equipped with an internal trap for condensate draining. Fit the inspection
union
A
and the flexible tube
B
, pressing it on about 3 cm. Fill the trap with approx. 0.5 l
of water and connect the flexible tube to the drainage system.
