SLEEVE AND MANIFOLD INSTALLATION
METHOD FOR STANDARD WALLS
1. Dis-assemble Manifold from Sleeve.
The flue consists of 3 parts, sleeve, inside
connectors and tube, outside terminal; (dis-
assemble by pulling hard on outside terminal
and inner connections, then pull sleeve off outer
terminal).
2. Adjustment of Sleeve Length.
Measure wall thickness through previously
drilled 80mm hole.
End of sleeve should protrude 5-10mm from
outside wall. Adjust sleeve length to wall
thickness plus 5-10mm. (Sleeve is threaded for
adjustment).
3. For A and S flues only
Depending on flue set and wall thickness
extension piece “C” may need to be removed.
Cut plastic, remove extension, then follow
instruction 2.
This applies to “A” and “S” flues only.
There is no extension on other flues, they can
be fully adjusted by turning the threaded
section.
4. Fixing Sleeve.
Fix to the wall, using the 3 screws provided.
NOTE:
The flange is marked “TOP”, sleeve must be
fitted with this mark UP.
Check sleeve protrudes 5-10mm on the
