k)
Unscrew the three nuts holding the heat exchanger to the back
panel; refer to Figure 43.
l)
Remove the heat exchanger.
m)
Disconnect the condensate drainpipe sump adaptor from the
heat exchanger.
n)
Remove the flue hood from the heat exchanger, two screws,
and fit the flue hood onto the new heat exchanger, Check integrity
of the flue hood seals and replace as necessary. Remove the
manual air vent and vent tube from the heat exchanger and fit
onto to new heat exchanger; refer to Figure 43.
o)
Fit the condensate drainpipe sump adaptor to the heat
exchanger and flue hood.
p)

return pipe 'O' rings and fibre washers and replace as necessary.
Ensure that all joints and seals are correctly re-fitted.
q)
Open the isolating cocks and vent air from the system using
the manual air vent. Re-pressurise the system as necessary and
check for water leaks.
Note: It is likely that the heat exchanger will still
contain water.
