INSPECTION AND SERVICE
Re-commission the burner:
1 Align burner combustion head (K) into the
boiler housing tube with gasket (O)
correctly fitted.
Push firmly down to compress the gasket (O).
Tighten burner retainers (H) sufficiently to
ensure a good seal.
IMPORTANT:
Ensure the gasket is a good seal between
the burner combustion head and the boiler
housing to prevent flue gases escaping
from the combustion chamber into the room.
Refit flexible air duct and secure with clip (J).
2 Refit the expansion vessel (D) onto the
support bracket (E) and taking care not to
kink the flexible hose or snag the thermostat
capillaries.
3 Plug burner lead (L) into control box (G).
Connect an oil pressure gauge to the oil
pump, run the burner and check the oil
pressure is correct for the required boiler
output. Check that the smoke reading is
between 0 and 1, if the smoke reading is
above 1 check the air setting. If the air
setting is correct check that the burner has
been reassembled correctly.
Allow the boiler to warm up then check the
combustion settings are correct as
indicated in the table below, adjust the
CO if necessary using the air shutter.
2
When the combustion is correct turn off the
boiler, remove the pressure gauge and refit
the blanking plug and plastic cover.
Refit panels:
4 Unlock supports (R) to pivot control box (G)
and slide into the boiler.
Secure with screws (C).
5 Locate top edge of panel (P) onto the top
supporting ledge (M) on the boiler.
Locate the ball stud connections (N) at the
base of the front panel (P) and push towards
the boiler to secure.
6 Locate the top panel (A) onto the ball stud
connections (B) and press down to secure.
After service handover:
Make a note of the date of any water treatment.
Set the controls back to the users
requirements.
Complete the service interval record at the
back of this manual and a CD11 or an
equivalent form.
If the appliance is unused and exposed to
freezing conditions; shut off all the mains
supplies, isolate the boiler and drain the
system and boiler, including the secondary
heat exchanger.
