SECTION 5 Start-up, operation and shutdown procedures (continued)
Hot syrup can cause severe burns. Always wear SAFETY GOGGLES and HEAT-RESISTANT
GLOVES AND CLOTHING when working with this equipment.
5.2 EVAPORATOR OPERATION
REFRACTORY CONCRETE COMPONENTS ON FIRST FIRING must be heated at a low temperature
to complete their cure and ensure a better longevity. Therefore, it is important to maintain the
maximum temperature of the combustion chamber at 1200 °F (650 °C) for at least 4 hours.
5.2.1
Lighting up the combustion chamber
To do pre-ignition
• Remove all ash from the combustion chamber floor.
Pre-ignition check
• Check:
- operation of the fans,
- if there are concentrate leaks,
- the correct positioning of the pans,
- that the insulation joints between each pan are in good condition and compressed,
- that the evaporator is well supplied with concentrate,
- the amount of the concentrate reserve to be boiled,
- that the amount of liquid in each pan is sufficient to function.
Clean the door window combustion chamber side before any firing as recommended in Section 6.4: Door
cleaning and maintenance, Ceramic window.
• Check:
- the proper condition of the gasket between the pans and the combustion chamber,
- that the following valves are fully open:
o concentrate supply,
o from the boiling rear pan to the syrup front pan,
o from the hot float,
- that the unit is switched ON.
Lighting up the combustion chamber
A RAPID COMBUSTION CHAMBER TEMPERATURE RISE MAY DAMAGE THE ARCH. The
following firing procedures are recommended.
• Use plenty of paper and cardboard to prepare your load.
• Place your load on the front half of the combustion chamber.
• Ignite the load; close the door; and turn the potentiometer (rotary knob) for the PRIMARY air fan(s) to
POSITION 2 and the SECONDARY air fan to POSITION Ø (Zero), for one to two minutes each.
