Single wall or Twin wall chimney
Single wall chimney may be used inside a building however we would recommend twin-wall insulated chimney.
Access for cleaning
Good access for cleaning must be included in the chimney system.
Connection to the rear of the appliance
- The F28 is only available as a natural draught chimney model. This is commonly fitted with a 90deg bend at the rear to allow for a vertical rise of the chimney.
- The F55 and F85 models can be supplied with natural draught chimney versions or our recommended flue fan versions.
- Whichever version is chosen we would recommend the first connection is a T pipe of 90deg or better still a 135deg T pipe.
Chimney support
The weight of the chimney should be supported by a stand and not the rear of the appliance.
Bends in a chimney
These should be kept to a minmium. Where a bend is needed it should be of no more than 45deg.
Chimney cowl
We do not recommend a chimney cowl as this can slow the volume of flue gasses. We recommed a cap of the connecting T pipe to include a drain point. This drain will allow any excess rain which enters chimney to exit the chimney system.
Routing Chimney through roof
There are several different methods to pass through a roof.
- The chimney must be supported as it passes through the roof. Commonly roof support is used.
- Any wood or flammable material MUST be at least 2" 50mm away from the outside of the twin wall insulated chimney pipe. (refer to chimney manufacturer).
- Prevent water ingress. A roof flashing should be used.
- In heavy weather conditions, it is possible to rainwater can leak between chimney and flashing seal. Use a storm collar attached above the flashing.
