Table 3 | Guide To The Potentiometers For Igniting The Oven - Lapierre FUSION X2 User Manual

SECTION 5 Start-up, operation and shutdown procedures (continued)
• Check that the combustion chamber fuel load is lit through the combustion chamber window.
• After 2 minutes and/or when the combustion chamber fuel load is well lit, leave the potentiometer for the
PRIMARY air fan(s) in POSITION 2, and turn the one for the SECONDARY air fan to POSITION 3.
• Monitor the temperature level indicators.
- The combustion chamber temperature should rise faster and be higher than the chimney temperature.
• When the combustion chamber temperature reaches 1000 °F (540 °C) or if the temperature stops rising and
starts to drop, turn all the air fan potentiometers to the Ø (Zero) position.
• To avoid flashback, wait 5 to 10 seconds before opening the combustion chamber door.
• Using a long poker, push the combustion chamber load backwards.
• Then place a feeder load of wood one to two logs thick over the entire surface of the combustion chamber. Start by
loading the rear and finish at the front.
• Close the door.
• Turn the PRIMARY air fan(s) potentiometer to position 2, and the SECONDARY air fan potentiometer to
POSITION 3.
• After 2 minutes, turn the PRIMARY air fan(s) potentiometer to POSITION 4, and the SECONDARY air fan
potentiometer to POSITION 2.
• It is recommended to use 32 in. (81.28 cm) long pieces of wood with a maximum diameter of 8 in. (20.32 cm).

Once the fire is started check
• Underneath the combustion chamber: check for smoke or hot air leaks.
• At the gaskets: check for leaks of smoke or hot air.
• Chimney: check for smoke or hot air leaks.
• Each pan: check the boiling distribution.
• Once the evaporator is boiling there shall be very minimal to no visible smoke emitted, except immediately
after reloading the combustion chamber.
