FLUE INSTALLATION
Installation of flue assembly
●
Fit rubber sealing collar
(F), see diagram 13,
into
groove at the outer end of pipe
(A).
●
Fit outer pipe
(A)
into wall with groove to the out-
side.
●
Pull pipe inwards to bring rubber sealing collar
hard up against external wall, see
diagram 14.
●
Fit internal plastic flange
(G)
onto outer pipe. Push
along the pipe until engaged against internal wall.
●
From inside, insert inner pipe
(B)
into outer pipe.
●
Fit both ‘O’ rings
(J)
into the flue elbow
(C),
one
at the inlet, one at the outlet. By necessity, they
are a loose fit, apply a small amount of silicone
grease to each ‘O’ ring when fitting.
●
Wrap sleeve
(D)
over outer pipe
(A)
and elbow
(C)
ensuring it is the correct way round.
●
Take hold of the inner flue and push gently onto
the elbow outlet taking care not to tear the ‘O’
ring.
●
Open fixing collard (
D
) and locate between
elbow and outer pipe (
A
). Close fixing jig.
●
Engage the two fixing clips
(E)
onto the colar
onto
(D)
and press down to lock into position.
Secure clips with screws provided.
Important
: If the flue has been cut, ensure that there
are no burrs that could damage the ‘O’ ring.
●
For flue systems less than 1,5 m long, leave the
restrictor
(a)
fitted in the fan outlet, see
diagram
15.
●
Remove the backing from the self adhesive gas-
ket
(H)
and carefully fit gasket to base of flue el-
bow.
●
Fit elbow onto boiler and secure with the four
screws
(I).
Concentric flue system
The maximum permissible length (
L
) for the concentric flue system is 3 m. For flue systems up to 1,5 m
length, the restrictor (
a
) supplied fitted to the boiler, inside the fan outlet, must be left in place. For longer
flue systems, the restrictor must be removed.
For each 90
°
flue elbow used, (or two 45
°
elbows) the maximum permissible length (
L
) must be reduced
by 1 metre.
