Flow direction Figure 9.8.2.b
Rear Flue
L = wall thickness (B) + 150mm
Side Flue
L = wall thickness (B) + distance between boiler and wall (C) + 150mm
If the length L is more than 580mm rear fl ue or 585mm side fl ue, then a
Horizontal fl ue fi xed length 1000mm (60/100mm) with elbow (FA100205)
will need to be used instead, up to 810mm.
Fitting the fl ue
Note : If it is required to cut an extension, DO NOT cut the end of the inner duct that incorporates the seal
joint.
Ensure the inner duct end without the seal joint is cut so that it is fl ush with the outer duct.
Ensure that all cuts are square and free from burrs.
Once assembled with the components pushed home, the fl ue is fully sealed.
1. Adjust the telescopic fl ue and secure with sealing tape supplied or cut the fi xed length terminal fl ue to the
required length.
2. Fit the fl ue to the extensions (if required) by locating the inner duct into the seal joint and push fully home
the inner and outer duct.
3. When connecting the horizontal fl ue terminal length ensure the terminal end outlet is at the uppermost
part of the fl ue.
4. Pass the terminal fl ue assembly through the wall.
5. Fit the bend to the boiler turret.
6. If the inside sealing collar (white) is being used, then it will need to be fi tted before assembling the fl ue
and making good the inside wall.
7. Pull the fl ue assembly towards the bend, locating the inner duct into the seal joint on the bend and secure
the fl ue assembly to the bend by pushing fully home (Outer fl ue duct must be seen through the small
inspection hole to confi rm fully home).
8. Make good the outside wall and fi t the outside sealing collar onto the location provided immediately
behind the fl ue terminal grille.
When mounting the fl ue gas system, pay attention to the fl ow direction (See
fi gure 9.8.2.b). It is not permitted to mount a system upside down and will lead to
complaints.
Use a soap solvent or special grease (supplied in the accessory bag with the
boiler) to simplify the fi tting.
The ATAG fl ue system used is a push fi t fl ue system, which does not require
screws to be fi tted at each fl ue joint.
The fl ue system must be adequately supported at regular intervals between
brackets of no more than 1.0 metres for horizontal sections and no more than
2.0 metres for vertical sections.
