Arriva/Evolve flue installation guide: 10726-I 09-21
Down-and-out flueing
The down-and-out flue option allows for the adaption flue kit to face downwards
and for the flue to run vertically through a hole in the floor, and then horizontally
to a suitable location outside. When considering the location of the heater
due care must be taken to ensure that the flue path under the floor is free of
obstructions such as studs, noggins, joists, braces, wiring etc.
