Flue Preparation - Glow-worm SwiftFlow 125 Instructions For Use Manual

7.1 Flue Length
For a rear flue, measure the distance from the outside wall face to
the boiler mounting wall. Check that the flue length will be suitable,
see diagram 3.1 for a standard flue system or diagram 3.3 for a 2
or 3metre flue system.
For a side flue, measure the distance from the outside wall face to
the side of the boiler mounting frame. Check that the flue length will
be suitable, see diagram 3.2 for a standard flue system or diagram
3.4 for a 2 or 3metre flue system.
7.2 Rear Flue
Note. Do not cut the flue duct at the pre-drilled end.
Mark the air duct/terminal assembly and the flue duct at the lengths
shown in diagram 7.1 then cut to length, cutting square and
removing any burrs.
7.3 Side Flue
Note. Do not cut the flue duct at the pre-drilled end.
Mark the air duct/ terminal assembly and the flue duct at the lengths

7.4 Flue Assembly
Locate the flue duct, drilled end, onto the flue elbow and secure with
screw supplied in loose items pack, see diagram 7.3.
Slide the spacer onto the flue duct.
Locate the flue duct/elbow into the air duct/terminal spigot and the
air duct/terminal into the flue elbow making sure of the correct
alignment of top. Drill the air duct and secure/seal (external fixing,
do not seal) as shown in diagram 7.3.
