Solutions
Pay attention to the following points in case of poor evaporator performance.
Check, over a 60-minute period, with a building door open to the outside, to see if evaporator temperatures rise
or remain the same. If temperatures rise, 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 outside, or with a door or window open.
1. Check the sugar content of your concentrate.
• Note this draft value for future reference.
2. About the combustion chamber fuel:
• Has there been a change in the combustion chamber fuel used?
• Is your combustion chamber fuel too damp?
- Measure the moisture content of the combustion chamber fuel with a moisture meter or other device
available at hardware stores.
o Combustion chamber fuel with a higher than normal moisture content, or higher than 25%, affects the
performance of the evaporator.
3. With the evaporator cold, turn the PRIMARY air fan(s) potentiometer to POSITION 9 (maximum).
• Check under the boiling rear pan to see if the fan(s) are running.
- If they are running, check that air is passing through the combustion chamber floor.
o If no air is detected, remove the ash and retest.
- If they are not running, correct the situation by referring to Troubleshooting Tip 7.2 One of the primary or
secondary air fans is not working.
o Then proceed with the airflow test through the floor of the combustion chamber in the previous
sub-point.
ATTENTION | 48 in. (4 ft. / 1.22 m) evaporators and larger are equipped with two PRIMARY air fans. For
this reason, you may detect air coming from the floor of the combustion chamber even if only one of the
two fans is operating. The accumulation of a large amount of ash on the floor can limit the supply of primary
combustion air to the combustion chamber and reduce the performance of the evaporator.
4. With the PRIMARY air fan(s) potentiometer in POSITION Ø (Zero), turn the SECONDARY air fan potentiometer
to POSITION 9 (maximum).
• Check under the boiling rear pan to see if the fan is running.
- If it is running, check that air is flowing through the nozzles located at the top of the two sides of the
combustion chamber.
- If they are not running, correct the situation by referring to Troubleshooting Tip 7.2 One of the primary or
secondary air fans is not working.
5. Check your chimney for any blockage.
