3 Flue Location and Ventilation
3.1 Flue Position and Length
There are several flueing options available for the Energysaver
Combi, e.g. horizontal, vertical and twin flue.
The standard horizontal flue is fitted onto the top of the boiler
using the flue elbow.
See diagrams 3.1 to 3.3 to determine whether a standard flue
can be used.
The standard flue can be extended using 1m long extension kits
and 90
°
elbows. A maximum of 3500mm of extension pipes plus
3x90
°
bends can be added to the standard horizontal flue
length.
NOTE: When extension pipes are used the flue system must be
designed to have a continuous fall to the boiler of at least 2.5
°
to facilitate the removal of condensate.
3.2 Internal Flue Installation
The flue can be installed from inside the building, when access
to the outside wall face is not practicable.

3.3 Terminal Position
The minimum acceptable siting dimensions for the terminal
from obstructions, other terminals and ventilation openings are
shown in diagram 3.4.
The terminal must be exposed to the external air, allowing free
passage of air across it at all times.
Being a condensing boiler some pluming may occur from the
flue outlet. This should be taken into consideration when
selecting the position for the terminal.
Car ports or similar extensions of a roof only, or a roof and one
wall, require special consideration with respect to any openings,
doors, vents or windows under the roof. Care is required to
protect the roof if made of plastic sheeting. If the car port
comprises of a roof and two or more walls, seek advice from the
local gas supply company before installing the boiler.
If the terminal is fitted less than 600mm below plastic guttering
or less than 450mm below painted eaves or a painted gutter, an
aluminium shield 750mm long should be fitted immediately
beneath the guttering or eaves.
