12 Horizontal Top Flue Installation
12a.4 Installation of horizontal top flue
assembly
Important: If the flue has been cut, ensure that there are no
burrs that could damage the ‘O’ ring.
• For flue systems less than 0,5 m long, fit the flue restrictor (a)
into the fan outlet, see diagram 10a.4.
• Remove the backing from the self adhesive gasket (H) and
carefully fit gasket to base of elbow (C).
• 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 suitable lubricant to each ‘O’ ring when fitting.
• Fit elbow onto boiler and secure with the four screws (I).
• Fit rubber sealing collar (F), into groove at the outer end of pipe
(A).
• Insert flue duct pipe (B) into inner end of air duct pipe (A), rotate
flue duct pipe to locate into groove inside air duct pipe.
• Fit air/flue duct pipe assembly through the wall with rubber
sealing collar to the outside.
• Fit internal plastic flange (G) onto air duct pipe (A).
• Fit the fixing collar seal (D) onto the flue duct pipe (B) ensuring
it is the correct way round (the larger diameter onto the pipe).
• Pull air/flue duct pipe assembly inwards to bring rubber sealing
collar (F) hard up against external wall, while carefully pushing
the fixing collar seal onto the elbow ensuring that the flue duct
pipe locates into the flue elbow outlet while taking care not to
tear the ‘O’ ring.
• Fit the fixing collar (E) around the fixing collar seal (D) and
secure with 2 screws provided.
• Push the internal plastic flange (G) along the air duct pipe (A)
until engaged against internal wall.
Horizontal Top flue system
The maximum permissible length (L) is 3.5 m.
For each 90
°
flue elbow used, (or two 45
°
elbows) the maximum permissible length (L) must be reduced by 1 metre.
