The mini-helic indicates the pressure generated inside the combustion chamber while the unit is in operation. The
pressure varies accordingly to the selected heat levels (1 to 5). To follow the suggested chart, press the combus-
tion fan icon (green) indicating a plus or minus to increase or decrease pressure. 10 settings are available to
calibrate the unit accordingly to the chart. The setting 5 will appear by default.
Important: The pressure indicated on the chart may vary accordingly to the fuel type. The
height of the fuel bed dominates over the pressure chart. The moisture and / or size of the
fuel may vary the pressure.
Note: Always refer to the fuel bed (embers) height in burner before decreasing or increase the pressure
displayed on the gauge.
Each heat level is factory programmed. The quantity of fuel per hour are displayed in the chart below. The length
or moisture can influence the flow per hour. Wood pellets varies in length from one manufacturer to another and
the moisture content and grain size also vary and can influence the flow.
Use the heat level 3 as a reference (see chart). Steps to follow: Empty the hopper and fill it with 40 lbs or 18.2kg
of fuel. Before startup, fill the measuring cup with wood pellets from another bag and start normally. Verify hopper
level after 16 hours of operation. To view how many hours, refer to page 15 tabs C for duration time. Then, check
every hour to see when the hopper is empty. A bag of 40 lbs or 18.2kg should last approximately 20 hours on heat
level 3, (40 lbs divided 2 lbs/h or 18.2kg divided .91kg = 20 hours)
Note: Refer to page 21 for adjusting the fuel flow.
