11.8.3. Mark and cut the air and flue ducts to length. Always
check the dimensions before cutting. Do not cut the drilled or the
expanded ends of the ducts. Make the cuts square and smooth.
11.8.4 Assemble the air and flue ducts and the terminal
assembly as shown in the diagrams. Do not forget to fit the flue
support to an extended duct system. Refer to Fig 31,32.
11.9.
Internal fixing of the ducts
11.9.1. Fit the wall sealing collar and fix in place using the clip.
Refer to Fig 33.
11.9.2. Tie a cord around the terminal from inside the flue duct
leaving enough to grip and pull the duct into position.
11.9.3. Push the flue system through the hole in the wall until the
sealing collar has passed through the outside wall.
Note:
At this point fit the wall mounting plate/manifold
assembly and the appliance. Refer to Section 11.7.7-10
11.9.4. Pull the cord to bring the flue sealing collar flush with
outside wall.
11.9.5. Fit and secure the air duct into the clamp as shown in
Fig.34. The air duct fits more easily if it is lubricated with soap
solution. Fully engage the duct into the clamp taking care not to
distort the seal. Tighten the three screws.
11.9.6. Pull the flue duct forward 50mm. Slide the flue clamp
over the fan outlet.
11.9.7. Refit the fan in the appropriate position ensuring that the
flue duct enters the fan outlet by 20mm before tightening the
clamp as shown in Fig 36.
Note:
Remove the flue hood clamp
wing-nut when a side flue arrangement is used. Replace and
tighten the wing nut after re-fitting the fan.
11.9.8. Re-connect the tubes and electrical connections to the fan
and air flow sensor ensuring that they are correctly positioned
and to the flue sample tube. The
RED
tube is to the positive
connection. Refer to Fig 22 and 23.
11.9.9. Make good the external brickwork or rendering. Make
good the internal wall as necessary.
11.10.
External fixing of the ducts
11.10.1. Prepare the duct assembly as described in Clause 11.8.
11.10.2. From outside ease the assembly through the wall.
11.10.3. Fit and secure the air duct into the clamp as shown in
Fig 35. The air duct fits more easily if it is lubricated with soap
solution. Fully engage the duct into the clamp taking care not to
distort the seal. Tighten the three screws.
11.10.4. Pull the flue duct forward 50mm. Slide the flue clamp
over the fan outlet.
