Step 7
Disconnect the two plugs from each other and the auger will stop.
Refit the pellet delivery hose onto the pellet feed tube of the burner.
WARNING
Ensure that the pellet delivery hose forms an air tight seal each end and
that the hose is not damaged. Leakage of air could cause increased
temperature in the pellet delivery hose and result in the pellet feed tube
thermostat shutting down the burner.
Step 8
Re-fit both the 6-way and then 7-way plugs to their corresponding sockets on
the left side of the burner. Ensure that both plugs are fully pushed home until the
small catch on each plug clicks into place.
Step 9
Make sure that the boiler pellet hopper is correctly located against the side of the
boiler with the front edge aligned with the top front edge of the boiler. Refer to
Figure 7-5.
Step 10
Finally, set the burner ON/STANDBY switch to the ON position.
8 Lighting your Boiler
To start your boiler:
•
First ensure that the electrical supply to the hopper and boiler is switched on.
•
Check that the heating system controls are operating and are ‘calling’ for
heat. There should be a cursor next to the ‘Heating Demand’ symbol on the
burner display. Refer to Section 5.4 – Active Symbols.
•
Set the burner ON/STANDBY switch to ON. The flue fan will start and pellets
will be delivered to the burner for it to start.
NOTE
If the burner ON/STANDBY switch is switched to STANDBY at this stage
the pellet feed will continue, and then the burner will go through the ‘WAIT
BOILER LIGHTING’ phase and light.
It will then immediately go to ‘TURNING OFF BRAZIER’ followed by ‘WAIT
POST PURGE’ and then stop.
This process will take several minutes to complete before the boiler can be
re-started.
•
The flue fan will start and pellets will be delivered to the burner. The boiler will
now light automatically after a short ignition period.
•
Set the heating (CH) and hot water (HW) functions on your programmer
to ‘Timed’. The boiler will now operate during the ‘on’ periods set on the
programmer.
CAUTION
Do not repeatedly switch the ON/STANDBY switch on and off the burner
at this stage, as a build-up of pellets in the brazier will occur resulting in
poor combustion during lighting.
