SAFETY
A wood evaporator can be a dangerous piece of equipment. Always wear heat
resistant gloves and clothing when you fire an evaporator. Often, visitors can be in
the sugarhouse. Make sure they stay at a safe distance from the evaporator,
especially children.
A wood evaporator works with solid material (wood) and produces intense heat in
front of the arch and around the smoke stack. For the location of your evaporator,
make sure you have a concrete or ceramic floor strong enough to support the weight
of the evaporator and its content as well as at least 24” between any wall and the
smoke stack. If you need to put it closer to the wall, a heat barrier (ceramic blanket
for example) should be installed. Also, make sure that your steam and smoke stacks
have a free way to the roof of the building (avoid rafters). Also, your ceiling should
be high enough for you to raise the hoods safely with a cable and pulley system.
IMPORTANT: Make sure to contact your insurance company in order to verify their safety
standards.
If your building is not insulated, you will have a better combustion and a better steam
evacuation. If it is insulated, you will need to have an air intake inside your building (air
trap, open window, etc)

INSTALLATION
1) Remove the wheels from the evaporator (if you have some).
2) Level your arch with the adjustable legs. Use a carpenter’s level onto the smooth rail
(pans are off the arch at this point) and adjust the leg adjustable bolts located at the
very bottom of the legs as needed.
3) Once the evaporator is leveled (length and width), make sure the locking nuts are
secured and tight.
4) Brick your arch (see drawing #C)
4.1 Place insulation board against inside arch panels using refractor cement to help
hold board in place if necessary. The insulation board can be cut with a utility knife
or saw. Always use a dust mask when insulating your arch.
4.2 Start placing firebricks in the firebox. Start around the grates and work up and
towards the rear of the arch. Refractory cement is applied in THIN layers only to
stick the firebricks to the insulation board and to each other.
4.3 The last layer of bricks at the top of the arch should be cut at an angle to allow heat
to touch as much pan surface as possible.
(drawing A). Do not force bricks into location. A too tightly bricked arch could
create problems.
4.4 Build a wooden form to allow you to pour castable concrete around the front end
of the arch. No bare metal should be exposed to the intense heat.
4.5 Fill the form slowly to make sure you have no air pockets in the concrete.
4.6 Allow 24 hours for concrete and mortar to set and dry with a room temperature
between 60 and 70 0F.
4.7 After a minimum of 24 hours, check to see if any area may need refractory cement
to fill any cracks or crevices.
4.8 Remove the form.
4.9 IMPORTANT: Make sure there is no air space between the top of the
bricks and the top steel rail. If there is, push in some wool insulation. If
heat directly hits the railing, it will warp.

4.10 It’s highly recommended to cure the concrete. Follow the following
procedure for optimal results:
a) Air cure at ambient temperature (no less than 400F and no more than
1000F) for 24 hours, keeping surface damp with light water spray, curing
compound or covering with plastic
b) Elevate temperature to 2500F and hold for 1 hour per inch of thickness
c) Elevate temperature 500F per hour to 5000F and hold 1 hour per inch of
thickness
d) Elevate 1000F per hour to 10000F and hold for 12 hours
e) Elevate 1000F per hour until 15000F, and let the temperature gradually
come back to the ambiant temperature.
Note: if at any time during the heat up excessive steaming is noted, STOP
the procedure at that point until steaming slows. If steaming is during a
holding period and continues for more than 15 minutes, reduce
temperature by 1000F
5) Place the pans on the arch. Start with the flue pan (the bigger one). Adjust it to the
back collar. Then install the syrup pan(s) on the front of the arch. Install the base
stack behind the flue pan and be sure that flue pan is levelled.
Don’t forget to install the insulation bars between each pan, they have to be
installed like this :
You don’t want the insulation to be touched directly by the flames.
6) Install the roof jack, base stack, stack pipe, collar and stack cover (please make sure
that the stack cover is installed, the cover has to be against dominant wind). Ideally,
have a rope coming down from the stack cover to a place where it is easy to operate.
7) If you have a drop flue pan, you need to raise the front of the pan (3/16”) to help
drainage.
