Installation “Sealed”; “Forced Open” Installation; Concentric Ducts - MHG Heating procon gwb smartline Installer And User Manual

draught sealed chamber accessories can be used, as they better adapt to
installation characteristics.
For fume extraction and burning air restoration in boiler, use original pipes or
other EC-certified pipes with equivalent characteristics; check connection is
correct as shown on instructions fume accessories provided for with. More
appliances can be connected to a single chimney, provided that all appliances
are sealed chamber type.
Boiler is a C-type appliance (sealed chamber) and must be safely connected
to fume exhaustion duct and burning air suction duct, both getting outside;
appliance cannot operate without these ducts.
9.2 - "Forced open" installation (Type B23P/B53P)
Fumes outlet duct Ø 80 mm (9.3-A)
The fumes outlet duct can be aimed in the most suitable direction for installation
needs.
To install follow the instructions supplied with the kit.
In this configuration, the boiler is connected to the Ø 80 mm fumes outlet duct
by means of a Ø 60-80 mm adaptor.
In this case, the combustion supporting air is taken from the room in
which the boiler is installed, which must be a suitable and ventilated
technical room.
Non-insulated fumes outlet ducts are potential sources of danger.
The fumes outlet duct must be inclined 1% towards the boiler.
The boiler automatically adapts ventilation according to the type of
installation and the length of the duct.

9.3 - Installation "sealed" (Type C)
The boiler must be connected to concentric or twin fumes discharge and air
intake ducts which must both be taken outside. Do not use the boiler without
them.
Concentric ducts (Ø 60-100 mm) (Fig. 9.3-B)
The concentric outlets can be placed in the most suitable direction for the
requirements of the installation, respecting the maximum lengths shown in
the table.
The fumes outlet duct must be inclined 1% towards the boiler.
Non-insulated fumes outlet ducts are potential sources of danger.
The boiler automatically adapts ventilation according to the type of
installation and the length of the duct.
Do not obstruct or narrow the comburent air inlet duct in any way.
To install, follow the instructions supplied with the kits.
Rectilinear length means without bends, outlet ends and connections.

Concentric ducts (Ø 80-125) (Fig. 9.3-B)
The relative adapter kit must be installed for this configuration. Concentric
ducts can be arranged in the most suitable direction for installation
requirements. To install, follow the instructions provided with the specific kits
for condensation boilers.

Twin ducts (Ø 80 mm) (Fig. 9.3-C)
The twin ducts can be aimed in the most suitable direction for installation
needs.
To install, follow the instructions supplied with the specific kits for condensation
boilers.
The fumes outlet duct must be inclined 1% towards the boiler.
The boiler automatically adapts ventilation according to the type of
installation and the length of the ducts. Do not obstruct or narrow the
ducts in any way.
The maximum lengths of individual pipes are shown in the graphs (Fig.
9.4).
The use of longer ducts will reduce the power output of the boiler.
Rectilinear length means without bends, outlet ends and connections.
