Thank you for purchasing a Wood-Mizer
Dehumidification Kiln and taking the first step
towards making the lumber industry cleaner and
more efficient! Years of development, innovation
and the highest quality materials have gone into
building your kiln, but it’s our dedication to
efficiency that sets Wood-Mizer’s kilns apart from
the rest and makes your system the best on the
market.
During kiln drying moisture in green lumber is
evaporated into the air increasing the humidity
inside the chamber. If the air becomes oversaturated
the lumber can’t continue to dry so moisture must
be periodically removed from the chamber. In
a conventional kiln moisture would be expelled
through venting. Venting causes a signicant loss of
heat requiring more energy to bring the kiln back up
to temperature.
Your Wood-Mizer Dehumidification Kilns doesn’t
waste energy through venting. Instead a
refrigeration system condenses the excess moisture
which is drained off and the existing heat energy is
recovered to be reused. After the moisture is
removed and heat is reintroduced to the dry air it is
pumped back into the kiln chamber to start the
process over. Unlike conventional kilns the heater in
your Kiln is only used during the initial warm up
and, sometimes, when temperature increases are
desired during the cycle, saving you time and
money. But that’s not all your new kiln has to offer!
Though Wood-Mizer kilns don’t rely on venting to
get rid of moisture, a Vent System is supplied to add
extra control of your kiln temperature. If the internal
kiln temperature exceeds what’s required, these
vents can be opened to remove excess heat and
bring the temperature back to where it needs to be.
And finally Wood-Mizer offers a wide variety of
upgrades and accessories to enhance your kiln
drying experience. See the upgrades and
accessories section on page 34 for more
information.
Concrete oors with insulation installed underneath
is recommended for best results. However if the
kiln is going to be on an existing concrete oor,
the insulation may be omitted. Concrete must not
extend beyond the kiln walls.
Wood oors may be used but must be built to
construction guidelines (see Pg 3)
If the kiln chamber is a freestanding outside
building, the attic space must be well ventilated
through the eaves. This is done to avoid any
moisture buildup in this space, which will condense
on the cold roof, dripping onto the insulation.
An interior kiln can have the ceiling insulation open
to the atmosphere.
Build ceilings to construction guidelines. (Pg 3)
At the front of the kiln chamber install bay/loading
doors with at least two sides hinges, and a center
door latch to close (recommended). Top hinged or a
lift o doors are also acceptable.
At least one access door should be installed in the
back of the chamber to allow for service of the
dehumidier and/or lumber monitoring.
All installed doors must:
•Be built to construction guidelines. However they
may be lightened by increasing the stud spacing and
using 3/8” plywood. The lighter weight will reduce
the load on the hinges
Please read through carefully as some options
may not apply.
By purchasing a Wood-Mizer Kiln you have the support
of Wood-Mizer’s service team, the very same
professionals that built and tested your unit.

•Have a vapor barrier.
•Have gaskets wherever the door meets the kiln; this
will give a good, airtight t.
•Have a scraper type weather strip to reduce air
leakage if door sill is not present.
•Close tightly against the gasket using turnbuckles,
tarp straps, lag studs with wing nut, etc.
Remember: There will be considerable expansion and
contraction during kiln use, plan door construction
accordingly.
While outside electronic moisture meters can be
used to avoid entering the kiln, during the drying
cycle, Wood-Mizer strongly recommends regular
checks inside the kiln to visually inspect the
surface or end checks, mold, stain and to check
with a hand held meter.
Step 4: Cover Thermax with one or two layers of
6 mil polyethylene, then enclose with ½” CDX or
marine grade plywood.
Step 5: Coat CDX interior surface with “mobile home
or metal roong aluminum paint”
Paint is an asphalt based coating with powdered
aluminum and ber for strength, available in
hardware stores. Re-coat as necessary every year.
Step 6: Finish exterior walls to suit your tastes, but
avoid galvanized steel or other ferrous sidings.
Once you have completed construction of the kiln
chamber install the following air deectors and
baes to control the airow within the chamber.
• Corner deector typically made of plywood used to
help turn the airow.
• Hinged bae that falls from the fan wall, to be held
up during load with a nylon rope. Hinged baes
compensate for dierent load sizes, and allow for
shrinkage of the board pile.
• Bae that closes in the open space for lumber that
does not ll the entire width. This bae can be xed
or portable.
Do not underestimate the eect of this baing, as
correct baing will pay o in more even drying and
faster drying. This more than osets the extra time
and eort to correctly place the baes.
Please reference Figure 1-2 for more information on
deectors and baes.
Please reference Figure 1-1 for more information on
construction.
Step 1: Build all walls, ceilings and oors with a 2” x
4” framework, with blue or pink Styrofoam (extruded
polystyrene) friction tted between the studs.
Step 2: Cover the interior face of the studs with a 1”
layer of Celotex Thermax (or for better results two
overlapped ½” layers).
Celotex Thermax is foil faced polyisocyanurate
(urethane) board which is orange or yellow in
color and is available in 4’x 8’sheets of various
thicknesses. Celotex Thermax is a trade name and
similar and acceptable products are available under
other trade names.
If you want to use spray foam insulation, urethane
based only applied at 2.2lb/cu ft. Fiberglass is never
recommended.
Step 3: Caulk joints and nail heads with high
temperature silicone (optional: apply aluminum tape
over silicone)

Please reference gures 1-1,2,3,4 and 5 for more
information on installation.
Step 1: Place the dehumidier at the center of the
long wall with the inlet lter facing the board pile.
Step 2: Connect an appropriate length drain hose as
shown in Figure 1-1.The drain must have a trap.
The dehumidier can be elevated any reasonable
amount to help the drain gravity feed. If the drain
hose extends outside (not to a oor drain in the kiln)
the wall opening should be sealed around the hose.
Never have a oor drain.
Step 3: Place the controller at a convenient point
outside the chamber near the dehumidier.
Step 4: Remove the cover
Step 5: Drill holes in the kiln wall to allow control
cables and separately the sensor wires (inside the
controller) to be carefully routed into the chamber.
Do not route control and sensor wires through the
same hole.
Step 6: Mount the Dry Bulb Temperature Sensor 6 to
12 inches from the wall 4 feet o the oor, at least 3
ft from kiln unit, away from the blower outlet, for an
accurate reading.
Step 7: Remove the right side panel of the
dehumidier gaining access to the compressor and
terminal strip.
Step 8: Securely connect the control cable to the
dehumidier.
Step 9: Carefully connect each wire to their
corresponding terminal. Do not stretch or over stress
the cable.
Wire insulation is marked with the corresponding
terminal number.
Step 10: Seal holes after wires are installed to keep
moisture from the control box. Seal the holes in the
kiln wall.
Step 11: Install the fans in locations over the lumber
see gures 1-1,2,3,4 and 5 as a reference.
Step 12: Install and caulk the vents so that they are
on opposite sides of the fans and at opposite ends of
the kiln.
The vents should be located as shown on the
chamber drawings.
Step 13: With the system switch in OFF position,
plug in the power cable (the special receptacle for
the KD150 is supplied by Wood-Mizer).
