and prevents equipment damage.
Empty Chamber Firing –We recommend that you fire your kiln empty for your first firing. This allows you to become familiar with the operation of
the kiln and controls without the possibility of destroying any glass.
Close both the lid and chamber –the kiln will not heat if either the lid or chamber are open.
Throw the power switch to the On position.
Refer to the controller manual and program your controls for a rate of 500°F/hour to 1200°F (260°C/hour to 650°C).
Start the firing.
As the firing starts you may notice a click sound or a series of click sounds (depending upon control type). This is normal and will end
briefly. The Studio Pro Series uses solid state relays to control the heat of the kiln. Solid state relays do not make any audible noise and you
should not hear any clicking sounds as the firing progresses.
Allow the kiln to heat up to temperature and shut off. Once off, allow the kiln to cool to a safe, low temperature of about 200°F (95°C)
before throwing the control power switch to the Off position and opening the kiln.

4.6 Operation – Firing
Actual operation of the kiln is a straightforward process. Consider the safety points above, and follow these steps;
4.6.1 Loading
●Ensure that the Kiln control power switch is thrown to the off position.
●Check that the items to be heated are of suitable size, weight and material.
●Position yourself to be able to safely access and handle the items to be heated.
●You may load your shelves and glass through an open lid or an open chamber –Dual Access!
●Take care not to contact the elements or the Thermocouple and minimize impacts with the inner surfaces of the kiln.
●We recommend to always use a primed refractory shelf as your firing surface with posts below it (1” posts are a good starting point)
and placing your glass on the shelf for firing. To say it another way, do not place your glass directly on the kiln floor and always post-up
your shelves.
●When placing shelves with the chamber open, always slowly lower the chamber to identify any contact of the shelves with the
chamber. If contact is made, re-position the shelves.
●The thermocouple works best if it’s not crowded against your work. Give it as much room as practically possible. Your firing surface and
glass should be positioned below the thermocouple. Avoid placing shelves above the level of the thermocouple.
●Check that you will be able to comfortably access and manage lid, chamber, shelves and glass when needed.
●Follow any manufacturers’ recommendations for materials being heated.
4.6.2 Setting Temperature and duration
●Kilns are equipped with temperature Controllers.
●Refer to the Controller documentation included with the kiln for programming methods. The controller manual for the Controller
installed on your Kiln is available at Evenheat-kiln.com/evenheat-support
●Follow all manufacturers’ recommendations for materials being heated.
4.6.3 Monitoring the firing
●Never leave a kiln unattended when in operation.
●Observe the kiln and surrounding area for any indication of a problem. Stop the firing if in doubt.
●If an interruption occurs during your firing, e.g., lose power/ no heat/ errors on controller, we recommend;
oPowering off the unit via the control power switch and allow it to cool.
oOnce cooled, remove any work/ware that is in the unit. Note: It’s possible that the work/ware is compromised, this would be
for the user to determine.
oRestart the unit and run a “test cycle” - take it up to 500°F/hour to 1000°F and determine if it is operating as normal.
oContinue as usual or begin further trouble shooting.
4.6.4 Shutdown
●Under normal conditions the Controller will complete the programmed cycle and move to the Off or standby mode.
●Throw the control power switch to the Off position.
4.6.5 Unloading
All safety recommendations should be followed to avoid any burn injuries.
●Ensure the area around the kiln is free of obstructions.
●Position yourself to be able to safely access and hand the items to be removed.
●Take care not to contact the elements or inner surfaces of the kiln.
●Carefully remove the items.
●When complete, close the lid and chamber.
Note - A kiln will remain hot long after the firing is complete.
4.6.6 Periods of Non-Use
When you have finished use for the day;

appropriate tool (Fig. 3), exposing jacket clamps (Fig. 4).
Grip each clamp with a pair of pliers and tighten the clamp screws. Fig. 5 illustrates using a screwdriver for tightening while Fig. 6
illustrates using a 5/16” socket. We prefer the use of the socket because it allows for a tighter clamp.
Once all clamps have been tightened, re-install the chamber handle assembly and lower the lid.

6.2.3 Fire Brick
The insulating fire brick while strong can be damaged with rough handling. Generally speaking, damage such as small grooves, chips or minor
cracks are acceptable. Any brick damage that potentially affects performance, such as a brick that holds the heating elements in place, should be
repaired. If you think a brick needs repair, please contact Evenheat for assistance and preferred repair methods.
If in doubt –ask.
6.2.4 Controllers
All our Controllers are maintenance free. In the unlikely event that you do need to replace a controller, instructions will be supplied with the
replacement part.
6.2.5 Control Fuse
The electronic controls are protected with a control fuse. Refer to the Technical Specification for location and type details.
Failure of the fuse is identified by a non-illuminated controller.
This is a user replaceable part.
If replacement is necessary, replace only with a fuse of the same size and rating.
6.2.6 Thermocouple and Thermocouple Wire
The thermocouple needs no maintenance other than replacement if it fails. Failure of the thermocouple is displayed as an error message on the
controls.
If thermocouple replacement is necessary, it should only be replaced with the genuine Evenheat replacement part. Replacing it with any other
thermocouple will introduce an error into the temperature reading.
Care should be taken to see that the extension wire be kept from harm. If the extension wire becomes damaged, it should only be replaced with
the genuine Evenheat replacement part. Replacing it with any other type of thermocouple will introduce an error into the temperature reading.
6.2.7 Control Relays
The kiln uses devices called relays to control power to the heating elements. A set of relays (mechanical) are connected with the Power Interrupt

switch and enables power only when the kiln lid and chamber are closed. Another relay set (solid state) controls the temperature of the heating
chamber.
Mechanical relays are a service part and will likely need to be replaced at some point. Solid state relays are generally considered to be a non-
service part and are expected to last the life of the kiln.
Access to the mechanical relays for replacement is via the Evenheat Control Center located at the back, rear of the base.
6.2.8 Heating Elements
The heating elements are made of special alloys that promote long life and element retention. Under normal operating conditions, elements
should last 10+ years. To maximize life, avoid getting debris on the elements and do not go beyond the rated kiln temperature.
In the event of heating element failure, contact Evenheat directly for instructions on replacement.
Loose debris that may accumulate in the sidewall grooves should be removed by periodically vacuuming the elements and element grooves. Prior
to vacuuming, ensure that the kiln is cold, unplug the kiln and gently and carefully vacuum the entire element groove.
