Roof terminal kit (C31)
The roof terminal kit is used when the gas flue discharges to a sloping
roof. These roof terminals are suitable as combined passages for the
discharge of combustion gases and the supply of combustion air for
closed gas-fired appliances. The connection is made using concentric
tubes of Ø 100
–
Ø 150 (fixed or flexible).

5.
Get the roof terminal level using a spirit level.
6.
Put the supplied mounting bracket on the roof terminal and attach it to the roof
boarding. Do not tighten the mounting bracket yet.
