7.2 Independent Operation from Ambient Air (Type C)
DANGER:
For room sealed operation, the boiler location and air/flue terminal
position must obey national and local requirements, gas safety regulations and
relevant standards.
Type C (hermetic) boilers are not suitable for outdoor installations. These boilers should be installed
inside the building.
In case of gas leakage, it is necessary to vent the installation room according to national and local
requirements, although the room sealed operation boilers are independent of room volume and ventilation.
DANGER:
Do not block the air vents, which provide fresh air to the installation room.
The air/flue terminal must be exposed to the external air and allow free passage of air cross
it at all times.
The minimum acceptable dimensions from the terminal to obstructions an ventilation
openings must obey national and local requirements.
All horizontally fitted ducts (air/flue) should be fitted 2° or 3° upwards incline to allow condensate water
drain to the boiler.
The flue ducts are always wet.
Under cold or excessive humid weather conditions the water vapor inside the
waste gas may condensate while leaving the flue.
7.3 Mounting the Combi Boiler
Having determined the boiler location,
The points of lock screws of wall bracket and assembly bracket are marked by using the wall-mounting
template provided with the boiler.
After drilling the marked points, wall assembly bracket and assembly bracket are fixed on the wall by
the dowel and lock screws, which are inside the packaging of the boiler.
Finally, the boiler is hanged on the wall by placing the assembly bracket on the back side of the boiler
on the mounting bracket assembled on the wall.
