The Evenheat Model 5320 is a classic manual electric kiln favored for its durability and straightforward operation. It is often equipped with a Kiln Sitter for mechanical shut-off. While older models are frequently found on the used market, their robust construction allows them to remain functional for decades with proper maintenance. Core Features & Specifications Firing a Manual Kiln with a Kiln Sitter
The Evenheat Model 5320 is a versatile kiln frequently used for glass casting, ceramics, and heat-treating. While official legacy manuals are often digitized as field guides or community PDFs, the core operation involves a multi-step digital controller that manages temperature ramps and holds. Core Programming Logic
Operating the 5320 requires programming a sequence of steps, each defined by three specific attributes:
Rate (C/Ramp): How fast the temperature changes (e.g., 300°F per hour).
Temperature (T/Sv): The target heat level for that specific step.
Time (Sv/Hold): How long to maintain that temperature once reached. Initial Setup & Troubleshooting When you first power on the controller:
Startup: You should see PASS in the primary display and 0000 in the secondary display. To unlock settings, use the arrow keys to enter code 2000 and press SET. evenheat kiln model 5320 manual
Sensor Check: If the duty cycle jumps to 100% within 3 seconds of turning it on, check your T1 (thermocouple) setting. It should initially reflect the room temperature.
Element Testing: To check if your heating elements are functional, you can perform a visual test by letting the kiln run for 10–15 minutes; they should begin to glow red. For a more technical check, use a multimeter to test for resistance (ohms) across the coils. Safety & Location Requirements
Spacing: Maintain at least 12 inches (ideally 18) between the kiln walls and any room walls to prevent heat buildup.
Ventilation: Ensure the room has strong natural ventilation or a forced fan system, as kiln firing can release gases.
Surfaces: Keep all flammable materials away and use steel shelving for hot tools and ceramic ware. Typical Firing Schedule (Glass Example)
A standard program for this model often follows this structure: The Evenheat Model 5320 is a classic manual
Initial Ramp: Heat to 1250°F at 300°F/hr; hold for 30 min.
Process Heat: Increase to 1420°F at 300°F/hr; hold for 30–60 min.
Annealing: Rapidly drop to 960°F (as fast as the kiln allows); hold for 90 min.
Cooling: Slow ramp down (e.g., 50°F/hr) to 800°F, then 100°F/hr to 600°F before turning off.
Let’s assume you are using a TAP controller. The Evenheat Kiln Model 5320 manual provides this exact workflow:
Meaning: Kiln exceeded setpoint by >50°F. Solution: This usually happens if your ramp rate is too high (e.g., 9999). The manual advises reducing the ramp rate by 50% and adding a "dwell" 100°F below target. Section 3: Step-by-Step Programming Guide (As per the
The Evenheat Kiln Model 5320 manual has a dedicated troubleshooting matrix. Here are common issues:
Symptom: Kiln won’t heat past 500°F
Symptom: Controller shows “Err” or “Sbr”
Symptom: Large temperature overshoot (+100°F)
SET and PAGE simultaneously for 5 seconds. Navigate to At parameter, set to 1, press ENTER. The kiln will cycle on/off for 30-60 minutes to learn its thermal mass.Symptom: Hot spots (blade bends during heat treat)
