Connection with coaxial pipes

fig. 21 - Examples of connection with coaxial pipes (

 = Air / 

 = Fumes)

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. Any horizontal sections of the fume
exhaust must be kept sloping slightly towards the outside, to prevent condensate from
flowing back towards the unit.

fig. 22 - Starting accessories for coaxial ducts

Before proceeding with installation, check  that the maximum permissible length is not
exceeded, bearing in mind that everycoaxial bend gives rise to the reduction indicated in
the table. For example, a Ø 60/100 duct comprising a 90° bend + 1 horizontal metre has
a total equivalent length of 2 metres.

Table. 2 - Max. length coaxial ducts

Connection with separate pipes

fig. 23 - Examples of connection with separate pipes (

 = Air / 

 = Fumes)

For connection of the separate ducts, fit the unit with the following starting accessory:

fig. 24 - Starting accessory for separate ducts

Before proceeding with installation make sure the maximum 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.

Connection to multiple flues

fig. 25 - Examples of connection to flues (

 = Air / 

 = Fumes)

To connect the boiler 

DIVAtop MICRO F

 to a multiple flue or a single chimney with nat-

ural draught, the flue or chimney must be expressly designed by professionally qualified
technical personnel in conformity with the current regulations and be suitable for sealed
chamber units equipped with a fan.

In particular, chimneys and flues must have the following characteristics:

•

Be sized according to the method of calculation given in the current regulations.

•

Be fumetight, resistant to the fumes and heat and impermeable to condensate.

•

Have a round or square section, with vertical run and without constrictions.

•

Have the ducts conveying the hot fumes, adequately separated or isolated from
combustible materials.

•

Be connected to only one unit per floor.

•

Be connected to a single type of unit (or all and only forced draught units or all and
only natural draught units).

•

Have no mechanical suction devices in the main ducts.

•

Be at low pressure, along the entire length, under conditions of stationary operation.

•

Have a collection chamber at their base for solid materials or possible condensate,
equipped with an airtight metal door.
