SAFETY FIRST
Read and understand all operating instructions before operating your kiln.
SAFETY PRECAUTIONS: Kilns are as safe as any other electrical appliance when
used under normal and proper operating conditions. All safety precautions throughout
this manual should be observed.
oUse common sense while installing and using this kiln.
oDo not install kiln closer than 12" from any surface, or closer than 18” from a
combustible surface. Remove all potentially combustible materials from the kiln
area
oMake sure all electrical specifications are followed. Use correct voltage, wire
size and circuit breaker. Make sure all connections are tight. Avoid using
aluminum wire. Always use the proper grounded receptacle. A qualified
electrician or service person should be used for all electrical service or repairs.
oInstall in covered, walled in, well-ventilated area. Do not allow your kiln to get
wet. Fumes from the ware should be vented to the outside. Never use your kiln
outside! Avoid moisture.
oAlways keep children and unsupervised personnel away. Surface will get hot and
a burn could result.
oFire glass only to the manufacturers recommended firing temperature. Improper
fire temperatures could result in damage to your kiln. Do not operate kiln over the
maximum temperature rating of 1700oF.
oReplace any worn or defective parts with ONLY genuine Jen-Ken Kiln
replacement parts.
oUnplug the kiln before servicing or vacuuming.
oDo not drop or slam the lid shut.
oLet the kiln cool to room temperature before opening the lid.
oNOTE: If you are in doubt about anything, call Delphi Glass 800.248.2048 or
Jen-Ken Kilns during regular business hours at 800.329.KILN.

ABOUT YOUR KILN
Introduction
The Delphi EZ- ProKiln 15-6 is a professional quality Jen-Ken kiln.
The controller has been designed and programmed to Delphi specifications by
Orton Ceramics.
Elements
Elements are the coils of wire that produce heat
inside the kiln. They are made from a high quality,
high-temperature wire. During the firing, they
become very soft and when cool become brittle. Life
expectancy of the elements will depend on the
number of firings and the firing temperatures. At
lower temperatures, the elements will last longer than
firing at higher temperatures. Care should be taken
to make sure that no foreign matter (such as glass,
glazes, clay or kiln wash) come in contact with the elements. This will greatly reduce
their life expectancy. Regular vacuuming of the kiln lid, bottom and the element grooves
is recommended.
In a digital kiln, the coils as a group turn on and off during firing. You will hear the
clicking of the relays. It will click more if a slow rate of rise in temperature is used and
less if the kiln is told to fire quickly. Your EZ-PRO kiln has separate relays for the top
and side elements to increase the life of the relays.
Glass kilns usually have coils in the lid and side walls. The lid coils do most of the work
in the kiln and get the hottest. Side coils are supplemental heat and help bring the kiln to
temperature. It takes the side and the lid coils to bring the kiln to fusing temperatures.
SAFETY FIRST: In a digital kiln, if a relay fails, the section that the relay controls might
not heat up, or could stay on continuously. If this happens, turn off the kiln at the
breaker and unplug. At this point, you will need to replace the relay. Call Jen-Ken Kiln
Company for assistance.
The EZ-Pro Kiln has multiple relays so that if one relay fails the kiln cannot heat too high
in temperature.

Kiln Brick
All Jen-Ken kilns are made of hand selected 2400°F
refractory brick. The brick is strong as a whole and
has a very long life. The brick can chip easily and
care should be taken to avoid bumps while loading
and unloading shelves. Frequently vacuum the brick
lid, the grooves that the elements are in and the
bottom of the kiln. This will remove the dust, sand
and loose kiln wash from the kiln.
Kiln Jacket
Your kiln is encased in a stainless steel jacket and is also equipped with handles for
easy moving. Due to the high temperatures, discoloration may appear on
the stainless jacket. A good metal polish will remove this discoloration.
Accessories
Shelves: Shelves help you make the most of the inside for your kiln. Shelves are sized
a few inches smaller than the inside diameter of the kiln so that they can be placed in
and out of the kiln more easily. They are made of refractory material so that they should
be handled carefully. Should a crack appear in a shelf, break the shelf along the crack
and use it as two separate pieces. A good coat of kiln wash should ALWAYS be
maintained on top of the shelves. Store shelves upright on edge, leaning on a sturdy
structure, not flat on their sides. Shelves stacked flat can put too much pressure on the
bottom shelf and cause it to stress and crack. Store shelves that are not in the kiln on
edge.
Posts: Posts are also made from refractory material
and should be handled carefully. Post sizes range in
heights from ½” to 14”. They are used to support the
shelves in your kiln at different levels depending
upon the height of the pieces you are firing. Usually,
three posts allow you to level the shelf more easily
(although some fusers prefer four).

RECOMMENDED
KILN ACCESSORIES
Glass Kiln Wash is a mixture of very fine minerals that will not fuse or
melt together at high temperatures and act as a barrier between the kiln shelf or mold
and glass. It is used to prevent glass from sticking to the firebrick bottom of the kiln and
the kiln shelves.
Kiln wash is a powder that‟s mixed with water to form a wash that‟s brushed onto kiln
shelves. When mixing, follow manufacturer instructions for powder and water ratio and
use care and do not breathe in the powder. (A DUST MASK IS RECOMMENDED) Kiln
wash has an unlimited shelf life in dry powder form.
The Haik Brush is a very absorbent natural bristle brush used to
apply kiln wash onto the kiln shelf in a very smooth, thin layer.
Kiln shelves and posts are made of a high-fired clay, like mullite,
that has been fired to temperatures that are higher than what can be
fired in your kiln. When working with glass in a kiln, you should
always fire your glass on either a kiln shelf or a mold. It is
necessary to coat the surface and edges of the kiln shelf with kiln
wash to prevent glass from sticking to it while firing.
Always wear Safety Glasses whenever you look into a hot kiln to
protect your eyes from infrared and ultraviolet light.
Hot gloves and / or Lid Lifter: An operating kiln is very hot.
These items can help preclude burns.

KILN SPECIFICATIONS
To operate the kiln safely and efficiently, your kiln needs the proper electrical outlet with
the correct electrical capacity and voltage. The chart below will assist you in the
selection of the proper wire and breaker size for your Jen-Ken Kiln. A licensed
electrician or the local power company should determine if you have the proper voltage
and wiring.

CHOOSING A LOCATION FOR YOUR KILN
The proper location is as important as choosing the right kiln. Below are some safety
guidelines.
oPlease review the safety considerations listed on page 5 when selecting a
location for your kiln.
oYour kiln should be located in a covered, dry, fireproof and well ventilated area,
but never in a small enclosed area such as a closet, cabinet or very small room.
Otherwise, the room temperature will increase past a reasonable level quickly. In
a larger room, the exterior of the kiln will stay cooler than in a very small room.
oYour kiln should be on a cement or fireproof surface and positioned a minimum
of 12” from any surface. The best and safest place for your kiln is on a cement
floor. If not, some type of adequate fireproof material should be used beneath
the kiln to prevent a possible fire hazard or prevent discoloration of the floor.
oConcrete blocks 8” x 8” x 16”, with holes up, may be used to raise the kiln to a
higher level. Solid bricks transfer heat through to the floor and should not be
used.
oAir circulation and ventilation are needed to remove heat and vapors that may be
released from the firing. In a larger room, the exterior of the kiln will stay cooler
than in a very small room. If ventilation is a problem, call to see if an Orton Vent
System or a hood system is applicable.
oProper electrical service must be available. Refer to the section on Electrical
Specifications. Select a grounded, three-pronged receptacle that is as close as
possible to either your fuse or breaker box. DO NOT use extension cords!
oRemove all flammable or combustible materials such as gasoline, paper, paints,
plastics, etc. from the surrounding area.
oSince the exterior of the kiln gets very hot, place the kiln out of the way of
children, traffic, and work areas.
oDo not let the power cord come in contact with the kiln. The kiln may need to be
rotated a little for the cord not to touch the kiln.
oNever install a kiln outside and avoid undue moisture.
