STEP 5 – Initial Firing of the Appliance
Before firing, ensure that the combustion pot and ash pan are in place as they may have been
displaced during transport/installation (refer to Figure 2). Switch the appliance on, ensuring all
controls are calling for heat.
Under normal conditions the appliance will proceed through the start-up sequence as shown in
Figure 16 on page 15. The appliance will use its temperature sensors to determine the required
heating demand for the property and, if conditions are met, proceed to the modulation sequence
shown in Figure 17.
During this time, observe the ‘Information’ menu in order to monitor time clock status,
temperatures, operating modes, draught and intake fan information. Guidance on typical values
is provided in Tables 2 and 3 of this document.
The combustion settings are factory set and cannot be altered, the exhaust fan works under
negative pressure (draws exhausted air out of the combustion chamber) and is controlled by the
differential pressure sensor. The intake fan is controlled by the lambda sensor fitted to the
appliance. Intake fan speed will modulate depending on the auger feed rate.
STEP 6 – Fuel regulation check
The fuel regulation feature regulates the fuel feed via the auger mechanism into the combustion
chamber of the appliance. Fuel regulation occurs in powerband 5 only, therefore the appliance
should be kept operational until powerband 5 is reached.
The main function of the fuel regulation feature is to automatically select the correct auger mode
to achieve the target intake fan speed of 7700rpm in Powerband 5. The following 3 scenarios
can occur during operation:
1. The appliance is operating in Powerband 5 and the intake fan speed is 7700 ± 300rpm.
Fuel regulation will not activate and the auger mode will not change.
2. The appliance is operating in Powerband 5 and the intake fan speed is
≤
7400rpm. Fuel
regulation will activate and increase the auger mode accordingly.
3. The appliance is operating in Powerband 5 and the intake fan speed is
≥
8000rpm. Fuel
regulation will activate and decrease the auger mode accordingly.
The appliance needs to operate in Powerband 5 and the flue gas oxygen content needs to
remain stable within permissible limits for a period of 13 minutes before any change in auger
mode will take place.
Navigate to the information screens to observe the intake fan speed of the appliance when firing
in Powerband 5. Refer to Figure 13 and 14. If the intake fan speed is low or high then the auger
mode should adjust as noted in points 2 and 3 above. The change in auger mode can be
observed in Parameters screen 3 (Refer to Figure 84).
A fuel regulation sequence is part of factory testing, therefore the auger mode of the appliance
at initial firing should be correct to achieve the required intake fan speed of 7700rpm. If not,
always allow sufficient time for the fuel regulation feature to activate.
NOTE – Fuel regulation will not activate if:
•
There is an active pellet level low alert – Ensure the fuel hopper is sufficiently full
•
The lambda sensor has been disabled – Refer to Figure 83 and Table 9
