2.1.10. Peripheral Distances of the Flue Outlet Connections

For positioning of the flue set outlet pipe, see Figure 16. The flue shall be installed in accordance with the national and local regulations.

No part of the outlet pipe or connections shall be blocked. If the outlet pipe passes1000 mm nearby of a plastic or painted groove or 500 mm of painted fringes, an aluminum shield with at least 1000mm length shall be placed below the groove or fringe. Outlet pipe shall be at least 2 m over surfaces within reach by individuals. Under certain weather conditions, outlet pipe may emit water vapor; installation shall not be performed at places where this vapor may cause discomfort.

Exhaust gases shall be prevented from entering flue ventilation spaces. Flue system of combi may be installed from inside the room without requiring intervention from the external wall. For that reason, an enclosure shall be installed in the wall for lining the internal surface of channel wherein the outlet pipe passes through the wall, particularly for thick walls.

2.1.11. Installation with (Ø80/125 mm) horizontal homocentric flue sets Connection of (Ø80/125 mm) horizontal homocentric flue set to the boiler

Since your boiler is a hermetic model, it takes the used air from outside and discharges exhaust gases created as the result of burning through the same flue group. In order to prevent emission of extremely harmful exhaust gases, flue usage and installation is very important, therefore warnings should be taken into consideration when flue connections are being performed.

• Carry out required flue selection for the external flue connection. If the standard flue set is not adequate, please select most suitable components from our list of connection accessories considering warnings given in our user guide.

Select the most suitable components by also considering our

warnings.

• Fix the flange under the Bend piece (1) by using the Flange Bolt (10) Flange Connection Screws (11) to holes on the boiler.

(10) secure it with Flange Connection Screws (11) onto the holes on

the boiler.

• 2 impermeability bolts within the hermetic flue set (2) are placed into internal pipe slots at both ends of the 90° Bend.

• Place the exterior wall (EPDM) bolt into the flue terminal as seen in Figure 11a for grouping the flue outlet terminal.

After placing the flue outlet terminal through exterior of wall and the

previously drilled hole, ﬁx the Interior Wall Connection Bolt (7) into the flue terminal. Place the other end of EPDM connection bolt installed on 90° flue bend of your boiler to the flue outlet. Ensure that sealings are placed properly:

VENTILATION

“Viwa 50 -65” boilers an be installed in boiler rooms whose size and requirements meet current regulations. The following is provide for your guidance only, and assumes the ventilation air is taken directly from outside.

The sizes of the vents may need to be increased inrespect of other appliances installed in the same area, and seasonal use. Take care that the position of low level vents would not subject to adverse weather conditions, ie flooding. Ventilation requirements for Viwa 50 -65 boilers and cascade systems. BS6644 has a requirement that the temperatures in a room or compartment do not exceed certain levels:

- +25°C at floor level (0-100 mm)

- +32°C at mid level (1.5 m above the floor level)

- +40°C at ceiling level (0-100 mm from ceiling)
