Your Kiln
How your Dehumidication Kiln Works
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. It’s our
dedication to eciency that sets Nyle kilns apart
from the rest making your system the best on the
market.
During kiln drying, moisture from green lumber is
evaporated into the air increasing the humidity inside
the chamber. The lumber can’t continue to dry if the
air becomes over-saturated therefore the 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 resulting in a waste of energy to bring the
kiln back up to temperature.
Instead of venting, Nyle Dehumidication Kilns
utilize a refrigeration system that condenses the
excess moisture. This moisture is then drained o
retaining the existing heat energy. 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.
Finally 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. 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!
Getting Started
Please read through carefully as some options may not apply.
Floors
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)
Ceilings
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
and drip onto the insulation.
An interior kiln can have the ceiling insulation open
to the atmosphere.
Ceilings must be built to construction guidelines.
(Pg 3)
Doors
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
• 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.

3
• 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 so it is imperative
to plan your kiln 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
ends for checks, mold, stain as well as testing with
a hand held meter.
Construction Guidelines
Please reference Chamber Plans for more information
on construction.
Step 1: Build all walls, ceilings and oors with a 2” x
4”framework using 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 ( for better results overlap
two 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, similar products
under other trade names are acceptable.
Note: If you want to use spray foam insulation, only
use urethane based spray foam applied at 2.2lb/cu
ft. Fiberglass is never recommended.
Step 3: Caulk joints and nail heads with a high
temperature silicone (optional: apply aluminum
tape over silicone)
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”
Note: Paint is an asphalt based coating with powdered
aluminum and ber for strength, available in most
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.
Baes and Deectors
Do not underestimate the eect of baing. Correct
baing will result in faster and more even drying.
The benets more than oset the extra time and
eort to correctly place the baes.
• Corner deector: typically made of plywood
are used to help turn the airow.
• Top Bae: Hinged bae that falls from the fan
wall to the top of the load used to compensate
for dierent load sizes, and allow for shrinkage
of the board pile.
• Side Bae: Bae that closes in the open space
when lumber that does not ll the entire width.
This bae can be xed or portable.
Please reference pg 13 for more information on
deectors and baes.
Power Vent
The Power Vent is to be secured to the inside of
the kiln wall with the fan side facing the exterior.

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.
Note: The dehumidifier can be elevated to any
reasonable amount to help the drain gravity feed.
The wall opening should be sealed around where
the drain hose extends outside of the chamber.
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. See “Wet Bulb & Dry Bulb
Installation” on the next page
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.
Note: Wire insulation is marked with the corresponding
terminal number.
Step 10: Seal the holes in the kiln wall after wires
are installed to keep moisture from the control box.
Step 11: Install the fans 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.
Note: 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).
The unit is now ready for the check out procedure.
