Installation
Flue considerations:
▶ If extensions are to be added then the complete flue must rise at an
angle of 3° or 52mm for every metre of flue length.
▶ When using a 100mm diameter flue, a 150mm diameter hole is
required through the wall. However, When installing the flue from
inside the property with the weather sealing collar fitted. Push the
weather seal through the wall until the seal is outside the building,
then pull the flue back until the seal is firmly up against the outside
face of the wall.
WARNING:
Risk of poisoning due to escaping flue gases!
Flue gases can escape from a damaged flue system.
▶ When drilling fixing points in the outer flue tube, take care not to drill
into the inner tube.
▶ Ensure all seals are correctly seated.
▶ Ensure joints are secured with the screws provided in the flue kit and
accessories.
▶ Ensure the flue system is adequately supported, approximately one
metre intervals and a change of direction.
▶ Ensure you carry out a flue integrity check when commissioning the
appliance.
4.1
Flue assembly
Correct orientation of the terminal assembly:
▶ Ensure that the words
TOP
on the terminal assembly are orientated
correctly before securing the fixed flue in position.
▶ This ensures rain ingress into the appliance is kept to a minimum.
▶ This must be done to allow the correct fit and use of the plume
management system.
Assemble the flue before fitting through the wall.
Refer to figure 15
▶ Slide the inner wall seal [1] onto the flue.
▶ Insert the flue [2] fully into the flue elbow [3].
▶ Ensure that words
TOP
[4] on the flue terminal are at the top.
▶ Secure the flue to the flue elbow with the two “self drilling” screws [5]
through the two pre-formed holes in the flue elbow.

Installing the fixed flue through the wall
WARNING:
Products of combustion
To ensure products of combustion do not enter the property through the
flue outlet.
▶ As a minimum, the flue must be sealed to the inner wall using a
suitable non-combustible building material and the rubber collar
fitted to the flue against the outside face. Providing the face of the
outside wall is flat then the rubber collar is considered to be an
adequate seal.
Refer to figure 16
Fitting the flue assembly
▶ Push the terminal [3] through the flue opening in the wall until the
outer seal is outside the building then pull the flue back until the outer
seal makes contact with the outer wall.
▶ Seal the inner wall around the opening with a suitable building non-
combustible material and then slide the decorative inner wall seal [1
] against the wall.
