OPERATING THE EVAPORATOR
Checking the furnace (before first use only)
1.
Make sure that the air inlets to the fire box are not obstructed (front, door, grates,
rear).
2.
Completely close the 4 gate valves under the evaporator (access through the panels
on each side).
3.
Start the blower.
4.
Open the door and check that some air is flowing through the duct under the door,
even when the gate valves are fully closed. This is a safety measure to prevent the door
from overheating. If you do not detect any airflow, contact your CDL representative.
5.
Stop the blower.
Before starting the evaporator
1.
Open the stack covers.
2.
Check that all water supply valves are functional and make sure that the outlets are
not blocked.
3.
Make sure the outlet on the evaporator feed tank is at least 12 inches higher than
the water level in the rear pan. Connect the tank to the rear float box.
4.
We recommend installing a thermometer on each syrup pan. Calibrate the
thermometers by placing them in boiling water and adjusting the temperature to
0 degrees.
5.
Open the valve of the maple water tank that leads to the flue pan. Fill the pan to
1 inch over the flues.
6.
Open the valve on the front float box and raise the water level in the syrup pans to
at least 2 inches.
7.
Using a tape measure, compare the actual reading with the scale reading on the
water levels and adjust if necessary.
(Note: In the rear pan, level “0” is equivalent to
a level above the terminals.)
8.
After the evaporator has been switched on, use the float boxes to stabilize the level
in the pans. We recommend 1 inch above the flues in the flue pan and 1½
–
2 inches
in the syrup pans.
9.
To check whether the arch is level, measure from the bottom of the pans to above
the water level in each corner of the pans; the measurement will be the same in all
corners if the arch is level.
10.
Make sure the valve on the water tank output is always open. If it is closed, you may
burn the pan.
