Thank you for purchasing a Nyle Dehumidication
Kiln and taking the rst step towards making the
lumber industry cleaner and more ecient! Years of
development, innovation and the highest quality
materials have gone into building your kiln, but it’s
our dedication to eciency that sets Nyle System’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 Nyle Dehumidication Kilns doesn’t waste
energy through venting. Instead a refrigeration
system condenses the excess moisture which is
drained o 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 Nyle 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 oer!
Though Nyle 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 nally Nyle Systems oers 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 Nyle Kiln you have the support of
Nyle’s service team, the very same professionals that
built and tested your unit. Enjoy your new system!

• 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,
Nyle 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 pg 13 for more information on
deectors and baes.
Please reference Chamber Plans 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 Chamber Plans 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.
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.
Step7: Removethe right side panelofthedehumidi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 Chamber Plans 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 L53
is supplied by Nyle).

Place the dehumidier at the center of the long wall
with the inlet lter facing the board pile. Connect an
appropriate length drain hose. The dehumidier can
be elevated any reasonable amount to help the drain
gravity feed. The drain must have a trap. If the drain
hose extends outside (not to a oor drain in the kiln)
the wall opening should be sealed around the hose.
Place the controller at a convenient point outside the
chamber near the dehumidier. Remove the cover.
Be sure controller is in a space that will not reach
temperatures below freezing. A light bulb located
near the controller and left on during the cold weather
is usually a sucient way to keep it above freezing.
Drill 2 holes in the kiln wall to allow control cables
and the sensor wire (coiled up inside the controller)
to be carefully routed into the chamber. Separate the
sensors from the power.
Mount the temperature sensor 6 to 12 inches from
the wall 4 feet o the oor and 3 feet from kiln unit,
for an accurate reading.
Do not place the sensor near the blower outlet.
Remove the right side panel of the dehumidier
gaining access to the compressor and terminal
strip. Securely connect the control cable to the
dehumidier. Note that each wire is marked with
the terminal number to which it is to be connected.
Carefully connect each wire to the similarly marked
terminal. Ground wire is yellow with a green stripe.
Do not stretch or overstress the cable. Seal the hole in
the kiln wall after the system check out is successfully
concluded.
Install and caulk the vents so that they are on opposite
sides of the fans and at opposite ends of the kiln. The
vents can be mounted to open to the inside or the
outside. It is usually more convenient if it opens to the
outside.
With the system switch in OFF position, plug in the
power cable (the special receptacle for the L53 is
supplied by Nyle).
Install the fans in locations over the lumber as
suggested on the chamber drawings.
The unit is now ready for the check out procedure.

Although not standard on Nyle DH Kilns you may choose to add on this optional Spray System Kit which will
provide extra control when drying. The Sprayers are designed to be automatically activated by the system
when needed and help with regulating the relative humidity within the kiln chamber.
Nyle spray systems are designed to inject into kiln air one gallon of water per hour for every 1000 BF. Because
air temperature aects the quantity of water evaporated (warmer air holds more water vapor), we need to
balance the quantity of water vapor to the kiln capacity. DH units with small heaters will require proportionately
less water than larger units with bigger heating capacity. There are options available for every unit so be sure
that the kit you are purchasing matches the specications for the unit that it will be installed in.
Nyle encourages boosting water pressure to 100 psi for the spray system to have the best results. Commonly
this is done with the use of a jet pump, which can be purchased through Nyle if requested. Contact your Nyle
Sales or Service Representative for more information.
