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- ProKiln 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.
