Installation and Servicing ecoTEC plus

8.1.4
General
All routine servicing requirements can be achieved by
the removal of the front casing, inner case and chassis
panel only.
Remove the two screws on the underside of the front
casing and lift off.
Remove the two screws on the front of inner case and
lift off, see fig 8.1.
Drop down the electronics box into the service
position.
Remove the four screws from the chassis panel, see
fig 8.2. Remove the chassis panel by pulling it out at
the top from its retaining slots.
Note!
When replacing chassis front panel ensure the
bottom fits behind lip.
Unless stated otherwise any part removed during
servicing should be replaced in the reverse order to
removal.
With the appliance operational carry out the following
functional checks:
1. Check the combustion, preferably with a flue gas
analyser, see section 9. If a flue gas analyser is not
available remove the outer and inner case, see figs 8.1
and 8.2, and taking care not to touch any components,
check the flame picture through the viewing window,
fig 8.3.
Should the flame show signs of lift, sooting or appear
yellow then it will be necessary to service the burner,
if the servicing does not correct the condition, then
proceed to the combustion test described in section 9.
2. Measure the gas rate during operation. If the gas
rate is lower than the minimum gas rate the burner
will require servicing.
Should the combustion measurement or flame and gas
valve be correct, then it is not necessary to remove
the burner assembly for a service.
3. Check the operational performance of the central
heating agrees with the technical specification.
