7.5 Flue gas discharge and air supply
7.5.1 General
The remeha W40/60-m ECO is suitable for room sealed
fanned flue or open flue fan assisted operation.
Separate flue discharge and combustion air inlet con-
nections are located on top of the appliance.
These are sealed with dust caps which MUST be remo-
ved just before the flue discharge and any air supply
ducts are fitted.
The boiler, in either single or multiple configurations is
suitable for operation with a wide variety of flue systems
(see section 7.5.2). Any horizontal runs of flue ducting
MUST slope back towards the boiler. Horizontal runs of
air ducting MUST slope towards the outside supply
opening. The flue duct termination must be located such
that when exposed to wind it will remain under suction
when the appliance is out of operation.
The flue should be constructed from single walled alu-
minium or stainless steel (316) and any air supply ducts
from either single walled aluminium, stainless steel or
plastic. All seams and joints in the flue shall be air and
watertight. When room sealed applications are adopted
all seams and joints in the air supply ductwork must be
airtight.
