Pipework
IMPORTANT
. The Heat Exchanger connections
are made using O rings and should not be
strained in any direction. Any strain will result in
damage to the Heat Exchanger and will not be
covered by the warranty.
All plastic pipework joints are solvent welded
and cannot be remade but have to be replaced.
Condensate Syphon
The lower bowl of the Syphon can be un-
screwed, examined and cleaned.
Air Duct & Flue Seals
A visual inspection should establish there are no
leaks around any of the seals, including the
flexible Air Duct to the Venturi.
Gas Rate & Combustion
See the Datatable on Page 1 for the correct
values.
A Combustion sample point is provided on the
front of the Flue Adapter. (
