Post-Ignition Start Up (First Fire Only/Commisioning)
Shortly after the stove is lit, a stove air pressure reading should be taken and the pressure monitored at fifteen
minutes intervals to ensure the stove and the flue are operating safely with sufficient air. As the stove and flue
warm, the supply of air being induced into the burner will increase, and it will be possible to increase the stove's
burn rate incrementally until the stove is running at maximum output. The entire stove and flue should be
allowed to reach normal operating temperature.
Reduce the control setting to No.1 (Low setting) After 5-10 minutes take a draft reading. This reading should be
within the requirements discussed in the Flue Pressure Adjustments and Requirements section of this manual.
Once the correct low fire chimney draft been achieved gradually increase the setting on the control allowing 5-
10 minutes after each increase. Once the control in is in the highest setting (No. 6) allow the unit to run for 10-
15 minutes. Adjust the draft stabalizer weight so the flue draft meets the required readings. You now have the
flue draft settings dialled in.
Carburator Adjustments:
With the chimney flue settings correctly set, the oil flow rates will need to be checked. This is normally checked
by the visual size of the flame. All adjustments to the control settings should be followed by 5 minutes of
undisturbed burn to confirm the change.
If needed, adjust these screw no more than one quarter of a turn at a time and allow the stove to
stabilize for ten minutes before making a further adjustments. Both screw and plate should be marked
to provide a reference of the original screw position.
High Setting:, Allow the stove to run at maximum output for at least 10-15 minutes. The flame should
be bright yellow and with the flame tips just short of the firebox ceiling. The base of the flames should still be
blue. The catalyser should be glowing red. If the flame is too high and allowed to impinge on the firebox ceiling,
soot will be generated. Adjust the "high-fire screw" on the control to achieve the proper flame.
Low Setting: Turn the control knob to the low setting and allow the stove to burn for a minimum of 15
minutes. The flame on low should be a small and completely blue. The catalyser should be a dull red. If there is
any yellow flame present then the "low-fire screw" must be increased until the there is only blue flame. At
minimum output, the flue stabilizer will normally be fully closed.
likely that further restriction of the flue will be necessary.
