Installation manual

cutting an extension of 1 m at the

required dimension.

The air/flue duct must be installed on a perfectly horizontal position since it already has a

minimum standard slant which prevents the condensate from dropping and freezing on the

ground.

The duct will be fixed following the relevant figures.

1. Cut the hole in the wall for the air/flue duct. Its minimum diameter should be sufficient

to allow the insertion of a plastic duct (as long as the wall and with ø130 mm) which will

be sealed with mortal. Cut the duct at the required length.

2. Before inserting the duct into the hole, insert the rubber sealing ring of the terminal part

(9 fig. 10) into the swage.

3. Insert the internal rubber sealing ring into the duct (9 fig. 10)

4. Push the duct outward until the rubber sealing ring comes out. Pull the duct inward and

align the ring on the wall.

5. Insert the gaskets (2) and (3) of fig. 10 into the bend. Push the flue ducts and the

external air inlet duct into the bend. The firm hold of every extension or bend which is

added must be warrantied by applying the necessary gaskets. Every vertical or

horizontal item must be fixed on the wall or ceiling by means of a suitable support. In

the event that a vertical extension is to be used, the terminal part of the duct should

have a horizontal outlet with a slant as previously explained.

2.22 ROOF OUTLET AIR/FLUE DUCT TYPE C33

To fit a Vertical Roof Cowl to Co-axial flue pipe, ensure the length of flue meets to Gas

Regulations and carefully fit the Cowl to both inner and outer pipes to allow combustion air

to enter the outer space of the flue and that the combustion air pipe is located in the inner

sleeve of the cowl.
