Poor Evaporator Performance - Lapierre FUSION X2 User Manual

SECTION 7 Troubleshooting kit (continued)
o The combustion chamber temperature sensor must be replaced.
o See Troubleshooting Tip 7.4 above, item No. 3: Combustion chamber indicator.
- The flame intensity increases, the combustion chamber temperature indicator increases, but the chimney
temperature does not.
o The chimney temperature sensor must be replaced.
o See Troubleshooting Tip 7.4 above, item No. 4: Chimney indicator.
3. Both the combustion chamber and chimney temperature indicators increase, but the combustion chamber
temperature remains below 1.5 times the chimney temperature.
• The lining and insulation of the combustion chamber and the smoke passage under the pans must be
checked and repaired. Contact your LAPIERRE EQUIPMENT service centre.
RECOMMENDATIONS
• The chimney temperature must never exceed 1000 °F (540 °C).
• The temperature of the combustion chamber must be 1.5 times or more higher than that of the chimney.
• To ensure efficient production of quality syrup, the evaporator combustion chamber temperature must be
maintained:
- 42 in. (3-1/2 ft. / 106.68 cm) and smaller evaporators: between 1500 and 2000 °F (816 and 1093 °C),
- 48 in. (4 ft. / 1.22 m) and larger evaporators: between 1250 and 1750 °F (677 and 954 °C).

7.6 POOR EVAPORATOR PERFORMANCE

Poor evaporator performance can be detected by unusually low values displayed by the combustion chamber
and chimney temperature indicators.
Solutions
Poor performance can be caused by:
• a lower than usual sugar concentration,
• poor quality combustion chamber fuel,
• a lack of combustion air,
• a blocked chimney.
