Before proceeding with installation, check with table 2 that the maximum permissible
length is not exceeded, bearing in mind that every coaxial bend gives rise to the reduc-
tion indicated in the table. For example, a Ø 80/125 duct comprising a 90° bend + 1 hor-
izontal metre has a total equivalent length of 1.5 metres.
Table. 2 - Max. length coaxial ducts
Connection with separate pipes
fig. 27 - Examples of connection with separate pipes ( = Air / = Fumes)
Separate Ø80 ducts can be connected directly to the unit.
Before proceeding with installation, make sure the maximum permissible length has not
been exceeded, by means of a simple calculation:
1.
Establish the layout of the system of split flues, including accessories and outlet ter-
minals.
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.

quired, proceeding as follows:
1.
Disconnect the power supply to the boiler.
2. Remove the casing.
3. Detach the electrical connections from the gas valve controller.
4. Unscrew the gas valve ( e ) fixing ring fig. 29“A” fig. 30.
5. Undo the two fixing screws “B” and remove the fan assembly as indicated in fig. 29
for the model ENERGY TOP W 70 - W 80 and in fig. 30 for the model ENERGY TOP
W 125 .
