INSPECTION AND SERVICE
Re-commission the burner:
1 Align burner combustion head into boiler
collar.
Locate the burner retainer (A) over the
threaded lug on the collar (B), push the
burner firmly onto the flange and secure in
place with the retaining nut (C). Tighten
sufficiently but do not overtighten.
Check that the burner is seated correctly
on its mounting flange and that the oil
hose/s are not trapped in front of or
underneath the burner.
Refit the deflector plate (D) and secure
with screws (E). Ensure that the flexible oil
pipe/s are not positioned between the
deflector plate and the combustion
chamber door.
Attach air duct pipe and tighten clip (F) to
secure to the burner air intake.
IMPORTANT:
Ensure the gasket is a good seal between
the burner combustion head and the boiler
housing to prevent flue gases escaping.
2 Plug burner lead (G) into control box (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 - 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 sample point cap, (hand tighten
only, do not over tighten) and refit the
plastic cover.
Refit panels:
3 Refit the top panel and press down to
compress the seal when fitting the
securing screws ( I ).
Push the front panel ( J ) up behind the top
panel and push in at the base to secure
with the twist lock screws (K) using the tool
provided.
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.
* 25/32 model for 25kW remove the plastic air
guide ( see page 38 ).
