SECTION 3 PLANNING THE INSTALLATION OF YOUR EVAPORATOR
To reduce the risk of fire, electric shock or injury, it is important to follow these instructions when installing your
equipment.
• If you have to work in existing walls and ceilings, be careful not to damage electrical conduits or other utilities
that may be present.
• Your VISION evaporator must be installed on a horizontal and perfectly stable surface.
3.1 LOCATING THE EVAPORATOR
3.1.1 Determining the location of the evaporator
It is essential to plan for the installation of your new evaporator before you receive it. To help you, Table 1:
Dimensions of evaporators, chimneys and vents by model shows you the dimensions to take into consideration.
With these dimensions, you will be able to organize the installation and determine the conditions below.
•IMPORTANT | The space between the evaporator and the walls must allow for traffic as well as the safe
operation of the equipment. This space must be more than 24 in. (60.96 cm) from each wall.
• There must be enough space on the draw off side to work safely.
• Determine the exact location of the evaporator in the building.
• Plan the installation of the concentrate supply lines.
• Determine where the evaporator chimney will pass through the ceiling and/or roof.
- Table 1 shows the dimensions to be planned in the ceiling and/or roof for the passage of the chimney and
steam vents.
- It is recommended that the evaporator’s chimney exhaust is centred between two roof trusses.
• Determine where the evaporator vents will pass through the ceiling and/or roof.
- Table 1 shows the dimensions of the ceiling and/or roof for the vent openings.
3.1.2 Determining the chimney length
Below you will find information on how to determine the minimum chimney length of your evaporator.
3.1.2.1 LWS listed chimney
From the location where the chimney will exit the roof, within a radius of 10 ft. (3.05 m), identify the highest
obstacle. This may, for example, be the roof gable.
Complete TABLE 2: Grid for calculating the minimum chimney height, with the following data.
a. Measure the height from the chimney exhaust location on the roof to the top of the obstacle (measurement a).
b . M easure the height from the floor to the location of the chimney exhaust on the roof (measurement b).
c . A dd the heights measured in a and b. The result is the minimum height of the LWS listed chimney that you
must install.
In this way, when the chimney rests on the VISION evaporator, it will be 3 ft. (91.44 cm) above the highest
obstacle on the roof within the specified radius.
NOTE: The chimney must be installed with a minimum clearance of 2 in. (5.08 cm) from all combustible
materials.

Lapierre Equipment | VISION EVAPORATOR | USER MANUAL | Version 03 - March 2023
SECTION 3 Planning the installation of your evaporator (continued)
3.1.2.2 Single wall chimney (non-listed)
From the location where the chimney exhaust will be located on the roof, within a radius of 20 ft. (6.1 m),
identify the highest obstacle. This may, for example, be the roof gable.
Complete TABLE 2: Grid for calculating the minimum chimney height, with the following data.
a. Measure the height from the chimney exhaust location on the roof to the top of the obstacle then add 7 ft.
(2.13 m) to the result (measurement a).
b.Measure the height from the floor to the location of the chimney outlet on the roof (measurement b).
c. Add the heights measured in a and b. The result is the minimum height of the single-wall chimney that you must
install .
In this way, when the chimney rests on the VISION evaporator connection, it is 10 ft. (3.05 m) above the highest
obstacle on the roof within the specified radius.
NOTE: The chimney must be installed with a minimum clearance of 24 in. (60.96 cm) from all combustible
materials.

SECTION 5 Start-up, operation and shutdown procedures (continued)
5.2.2 Syrup production
Below is a list of points to check when making maple syrup.
• Monitor the water level in each of the pans.
• Monitor the temperature in the chimney.
- The reference temperature of the chimney to keep in mind is above: 850 °F (450 °C).
- LAPIERRE EQUIPMENT suggests using this reference as the minimum starting temperature.
- This reference will be used to determine when combustion chamber fuel refills are required.
o A temperature below this reference indicates that a refill is required.
- Evenly distribute coals and embers with a poker, load a fresh load not above the middle of the door window.
- Monitor the temperature of the chimney regularly.
- IMPORTANT | At all times, the chimney temperature must not exceed:
o 1000 °F (540 °C) for VISION equipment with STANDARD or DELUXE pans,
o 1200 °F (650 °C) for VISION equipment with ACCORDIAN PLEATED pans.
• Regularly check the Brix concentration of the syrup at the drawing valve.
5.2.3 Changing the syrup pan
Below are the instructions to follow when changing the syrup pan.
• Check the condition of the gasket between the pans and the combustion chamber.
• Check the insulation joints between the pans.
- IMPORTANT :
o a syrup soiled gasket must be cleaned,
o a blackened or damaged gasket must be replaced immediately or very quickly.
• Check that there are no concentrate leaks under the boiling pan.
• Check the boiling rear pan for cleanliness and accumulation of sugar stones.
• Before replacing the syrup front pan, make sure the fireproof bead is fully raised to its position.
5.3 EVAPORATOR SHUTDOWN
Below are the instructions for shutting down your evaporator.
• Make sure you have a minimum reserve of 2 hours of concentrate or water.
• Stop feeding the combustion chamber.
• Although the coals burn out quickly it should be noted that the heating of the pans will continue for some
time due to accumulated heat in the evaporator.
• After 2 hours, turn off the water or concentrate supply to the evaporator.
• Close the valve located between the boiling rear pans and the syrup front pan. For the 18 x 48 in. mono pan
(single pan) close the opening between the rear accordion section and the front section with the supplied
plug.

6.4 DOOR CLEANING AND MAINTENANCE
Below are the instructions for cleaning and maintaining the evaporator door.
Ceramic window
• Cleaning the window from the inside. You may use either of the following two methods:
- a paste designed for the maintenance of ceramic cook tops with a cloth,
- ash with paper towels or a damp cloth.
• Replacing the glass from the outside.
- First unscrew the stainless steel frame.
- Remove the seal that holds the glass in place.
- Remove the glass and replace it with your new glass.
- Replace the new seal in the correct position.
- Screw the stainless steel frame back in place.
Door seal and insulation.
• Replace the seal and insulation if damaged.
- Remove the lugs that hold the insulation mat in place.
- Remove the insulation mat.
- Using a drill, pierce the rivets of the plates that hold the door seal in place.
- Insert the new seal and then attach the plates back in place using rivets.
- Replace a new insulating mat.
- Replace the lugs that hold the insulation mat in place.
6.5 EVAPORATOR CLEANING
• The stainless steel components of your equipment must be cleaned with a product specifically designed for
this purpose. Do not use flammable liquids.
• Never use abrasive products, products containing chlorine or muriatic acid (also called hydrochloric acid) to
clean the components of your evaporator.
• The use of wire brushes and steel wool should also be avoided.
During prolonged storage, even the slightest CLEANING PRODUCT RESIDUE ON ALL
COMPONENTS will obviously lead to inconvenience and damage at the beginning of the next
season. Rinse each cleaned component thoroughly.
