SAFETY
Wood-burning evaporators are very powerful pieces of equipment. They can be
dangerous if the operator does not follow the recommendations in this guide. Always
wear heat-proof gloves and clothing when operating an evaporator. Visitors must also be
informed of potential hazards and should keep a reasonable distance from production
equipment at all times.
Wood-burning evaporators run on solid fuel and produce intense heat that could cause
serious burns, both when the door is open and when it is closed. Some metal components
can also be hot enough to create flash burns, mainly around the door, pans, and stacks.
Operators must also watch out for boiling syrup splashes and steam backflow, as they
may cause burns.
The evaporator should be installed on a fireproof surface that can bear the weight of the
equipment and its contents. It should have at least 24 inches of clearance on all sides. If
you need to place the evaporator closer to a wall, install a heat-resistant coating on that
wall. Make sure that the stacks are not blocked by roof trusses. Correctly sized jacks must
be installed for any stacks that run through the roof. We also recommend that the ceiling
of the cabin be high enough to allow you to safely lift the hoods (if applicable) with a cable
and pulley system.
IMPORTANT: We strongly recommend that you contact your insurance company to
make sure that the evaporator is installed according to their safety rules, as different
companies have different requirements.

INSTALLING THE ARCH
You will have better combustion and steam will exit more easily if your building is not
insulated. If it is well insulated, you will need to make sure you have air inlets to improve
combustion and stack draft.
1. Place the evaporator in the chosen location, remove the delivery wheels, and install
the adjustable feet (included) in the indicated spots.
2. Remove the pans and accessories from the arch.
3. Using a level, adjust the legs so that the bottom of the arch is perfectly level along the
length and width. Tighten the nuts at the bottom of the legs.
4. Connect the evaporator to the tank(s), making sure that there is a valve to block the
water if necessary.
5. Have a certified electrician connect the blower and controls. (Note: the controls must
be powered according to the electrical diagram in the main control panel.)
CLEANING BEFORE FIRST USE
Before using your evaporator for the first time, prepare a hot soapy water solution and
add the equivalent of one cup of vinegar (250 ml) or ½ oz (15 ml) of acetic acid per gallon
(4 L).
Hand clean any components, such as stainless steel pipes, fittings, and valves, that may
come into contact with maple water or maple syrup. Rinse and dry the components with
a soft, clean cloth. This removes any residual manufacturing oil, polish, and/or packaging
debris.

BRICKING
Here is the procedure for bricking your arch. You can also view a full bricking manual on
our website:
https://www.cdlinc.ca/wp-content/uploads/2018/05/Bricking-instructions-1.1-EN_low.pdf
Please note that we offer a bricking service. Contact your CDL representative for more
information.
1. Place the ceramic wool against the inside walls of the arch from the bottom of the fire
box upwards. Leave an 8-inch overhang on top of the rail and cut with a retractable
knife. Tape down the excess if necessary. Dust masks must be worn when insulating
the evaporator.
2. Use heat-resistant bricks to brick the bottom of the arch, followed by the walls. Start
at the front bottom and gradually work upwards and backwards. High-temperature
mortar must be applied in a thin layer behind and between the bricks to keep the
bricking solid and seal any gaps.
3. The last row of bricks at the top should be cut at an angle so that the heat from the
fire covers as much of the area under the pans as possible. Do not force the bricks
under the top rail. The bricks will always move slightly when heated. If they are too
tight, the arch frame will warp. Leave approximately ¼ inch between the top of the last
row of bricks and the rail. (Diagram A)
4. Cut the excess ceramic wool at an angle, following the angle of the cut of the last brick.

5. Build a wooden form for a Pyromix cement wall around the top, the bottom of the
door, and the upper rear sections of the fire box. The metal surfaces should not be
directly exposed to heat. IMPORTANT: You must tape over the air outlets to prevent
cement from getting inside.
6. Slowly fill the form with high temperature cement. Make sure there are no air pockets
in the form.
7. Let the cement stand for at least 24 hours between 60 °F and 70 °F to let it dry; you
can add a heat source if needed.
8. Remove the wooden form, break the cement opposite the air inlets (if necessary), and
remove the tape on the air outlets.
9. Check for cracks in the cement. If you find cracks, fill them with cement to create an
even surface.
IMPORTANT: Contact your insurance company to make sure that your installation
complies with its safety rules.

ASSEMBLY
Now that your arch has been bricked and insulated, you can assemble the pans, jacks, and
collars.
1. Install the pans on the base, starting with the rear spacer and the flue pan (the largest).
Do not forget to install the pan spacers. Next, install the syrup pans in the front. You must
have an insulating pan spacer at each joint; make sure to install them with the curved
edge facing up (see photos). Check that the pans are level and clamp them properly
together using the front pan clamp.
2. Install the jack(s) on the roof; each jack must be perfectly aligned with the stacks on
the evaporator. Make sure the joint is tightly sealed to prevent leakage. (In order to
avoid complications with potential claims, we suggest you check with your insurance
company to find out the required clearance for the smoke stack as each insurance
company has its own rules.)
4. Using rivets or self-piercing screws, install the entire provided smoke stack, starting
with the base and including the strip of insulating wool at the base of the stack. Install
all pipes supplied with the evaporator; the pipes must be at least twice as tall as the
length of the evaporator. The pipes must extend 2 feet beyond the pinion.
5. Install the steam stacks (if applicable) following the same procedure.
6. Place the collars, then install the China cap and/or stack covers on the outside of the
building. Hinged stack covers will require you to run a cable for opening and closing
the cap from inside the building. (Note: Hinged stack covers should always be installed
in a way that prevailing winds can close the cap.)
7. Attach steel cables to the pipes to keep them attached and in place. Do not tighten the
cables too much, as the stack expands as it heats up.
8. Remove the protective plastic film from the stainless steel finish on all evaporator
parts. (Note: The film can be very difficult to remove in cold weather.)

9. Install the float boxes, fittings, and water level(s). Connect the evaporator’s water inlet
to your tank. The lowest level of your tank should be at least 12 inches above the
evaporator’s maximum water level. Place Teflon tape on all threads to prevent
leakage.
Once the bricking is finished, we recommend curing the cement to maximize the lifespan
of the brickwork. Here’s how:
1. Air cure at room temperature (stack temperature must be between 40 °F and 100 °F)
for 24 hours, keeping the surface of the cement moist by lightly spraying it with water
or covering it with plastic.
2. Fill the pans with water as you would when boiling.
3. Raise the stack temperature to 400 °F and maintain it for 3 hours.
4. Gradually lower to room temperature and let it rest for 24 hours. This will prevent
thermal shock and help limit cement cracking.
