Your Kiln
How your Dehumidication Kiln Works
Thank you for purchasing a Nyle DH Kiln and
taking the rst step towards making the lumber
industry cleaner and more efcient! Years of
development, innovation, and the highest quality
materials have gone into building your kiln. It’s
our dedication to ef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
off, 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. Sometimes, temperature increases
are desired during the cycle, saving you time and
money. But that’s not all your new kiln has to offer!
Though Nyle kilns don’t rely on venting to remove
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 offers a wide variety of
upgrades and accessories to enhance your kiln
drying experience. See the upgrades and accessories
section on page 45 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
A Concrete oor with insulation installed underneath
is recommended for best results. However, if the
kiln will 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.
The 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 lift-off doors are also acceptable.
At least one access door should be installed in
the back of the chamber to allow dehumidier
servicing 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 the 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 handheld meter.
Construction Guidelines
Please reference The 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 a foil-faced polyisocyanurate
(urethane) board that is orange or yellow and is
available in 4’ x 8’ sheets of various thicknesses.
Celotex Thermax is a trade name; similar products
under other 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 the construction of
the kiln chamber, install the following air deectors
and bafes to control the airow within the chamber.
Bafes and Deectors
Do not underestimate the effect of bafing.
Correct bafing will result in faster and more
even drying. The benets more than offset the
extra time and effort to place the bafes correctly.
Corner deectors: typically made of plywood,
are used to help turn the airow.
Top Bafe: A hinged bafe that falls from the fan
wall to the top of the load used to compensate
for different load sizes and allow for shrinkage of
the board pile.
Side Bafe: A bafe that closes in the open space
when the lumber does not ll the entire width.
This bafe can be xed or portable.
Please reference pg 14 for more information on
deectors and baf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 The 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 a proper length drain hose. The
drain must have a trap.
Note: The dehumidier 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.
Note: Be sure the controller is in a space that will
not reach temperatures below freezing.
Step 4: Remove the cover
Step 5: Drill 2 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 E+E Sensor See “E+E Sensor
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 its
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 the OFF
position, plug in the power cable (the particular
receptacle for the L200 is supplied by Nyle).
The unit is now ready for the check-out procedure.
Equipment Installation
Sensors
E+E Electronic Sensor
The E+E Electronic Sensor replaces the Dry bulb
and Wet bulb sensors as well as it’s function on
the L200 Pro Controller.
Additional Probes
The Controller also still has 2 x PT100 probes
which can be used as traditional Dry bulb and
wet bulb sensors by disabling the Electronics
Sensor on the Advanced page of the touch
screen controls
E+E Sensor Installation
The Electronic Sensor probe is mounted on the
Dry bulb sensor bracket approximately 3-4 ft
from the oor and roughly 6-12” from the loading
door against the side wall that is closest to the
control box
