Smoke Exhaust - Lapierre FUSION X2 User Manual

SECTION 7 Troubleshooting kit (continued)

7.11 SMOKE EXHAUST

The FUSION X 2 evaporator uses combustion air fans that pressurize the combustion chamber. This pressurization
can cause smoke to leak into various parts of the evaporator.
Solutions
The following are troubleshooting tips for smoke infiltration at the following locations.
1. AROUND THE DOOR
• Replace the door sealing ring.
2. UNDER THE PANS
• LEVEL: Check that the evaporator is level.
• LEGS: Check that the adjustable legs are all in contact with the floor.
• INSULATION JOINT Inspect the condition of the insulation joint between the pan and the evaporator frame.
A damaged or blackened joint must be replaced.
3. BETWEEN THE PANS
• Check pans for deformations or dents. Replace as needed.
• Check the condition of the pan joint. Replace as needed.
4. THE CHIMNEY JOINTS
• SMOKING AT START-UP ONLY: No consequences.
• DOOR TO THE OUTSIDE OPEN:
- SMOKING STOPS: If the smoke exhaust stops when an exterior door is opened, the building is too airtight
and it is necessary to operate the evaporator with a 24 x 24 in. (60.96 x 60.96 cm) opening to the exterior.
- SMOKING CONTINUES: If the smoke continues to escape when a door to the outside is opened, the
chimney is blocked.
o RAIN CAP: Check to see if the rain cap is open or if it is not obstructed by debris such as a bird's nest,
leaves, etc.
o DEBRIS: Check for debris inside the chimney.
