STRATTON MK3 - Installation, Use and Maintenance
4.3.4. Assembling the flue
Flue terminals or extension ducts may be cut to shorter lengths if required
When cutting a duct ensure it is square by marking the length all the way
around and only cut back the plain end.
When cutting concentric duct, it is important that the inner duct is maintained
at 20mm longer than the outer duct to allow correct connection of the ducts.
Care should be taken to support the inner duct when cutting the flue. When
assembling only use water as a lubricant.
Note. Horizontal flue runs must be angled down between1.5° - 3° towards
the water heater to allow the condensate to drain. For this reason, it is
recommended that a support bracket is used for every 1m of extension pipe.
See below for flue assembly examples.
Cut the white terminal tube to the correct length and ensure the painted wall
plate is pushed hard up to the black terminal collar when fitted.
IMPORTANT:
There should be NO white terminal tube visible when viewed from the
outside.
