Re-commission the burner
1. Align burner combustion head into the boiler collar.
▶ Locate the burner retainer [A] over the threaded lug on the collar [B],
push the burner firmly into the flange and secure in place with the
retaining nut [C]. Tighten sufficiently but do not over tighten.
▶ Check that the burner is seated correctly on its mounting flange and
that the oil hose/s are routed correctly as shown on page 19.
NOTICE:
Ensure the o-ring seal between the burner collar and
mounting flange is in good condition to prevent flue
gases escaping from the combustion chamber into the
room.
2. Refit the flexible air duct and secure with clip [D].
3. Swivel the expansion vessel [F] back into position taking care not to
kink the flexible hose or snag electric cables.
4. Plug burner lead [G] into connector [H].
▶ 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
table 9, adjust the CO if necessary using the air shutter. When the
2
combustion is correct turn off the boiler, remove the pressure gauge
and refit the blanking plug and plastic cover.
