The Evenheat Model 5320 (often referred to as the 5320 XL) is a discontinued manual ceramic kiln typically equipped with a Dawson Kiln Sitter. Because it is an older model, the exact "5320" manual is often bundled into broader Evenheat Discontinued Manuals or general Ceramic Operating Instructions. 🛠️ Key Specifications
Control Type: Manual, typically featuring infinite switches that cycle elements on and off for temperature control.
Safety Device: Usually a Kiln Sitter Model K that uses pyrometric cones to shut off power.
Electrical: Operates on 240V, often requiring a 30-50 amp circuit depending on the specific sub-model.
Elements: Replacement heating elements are available via The Ceramic Shop for both 5320 and 5320XL variations. 🚦 Basic Firing Procedure evenheat kiln model 5320 manual
For manual models with toggle or infinite switches, use this general profile:
Initial Ramp: Set all switches to "Low" for the first 2 hours to drive out moisture.
Medium Phase: Turn switches to "Medium" for another 2 hours.
High Phase: Turn all switches to "High" until the Kiln Sitter trips and shuts off the unit. The Evenheat Model 5320 (often referred to as
Venting: Keep the top lid propped (using the lid prop) or leave the top peephole open during the first few hours to allow gases to escape. ⚠️ Vital Safety & Maintenance How to Operate a Manual Evenheat Kiln
Q: Can I fire the Model 5320 vertically? A. No. The manual explicitly states horizontal operation only. The element channels are gravity-dependent.
Q: My kiln turns off mid-cycle. Why? A. Check the door limit switch (if equipped) or the power cord connection. The manual notes that a loose plug will heat up, increase resistance, and drop voltage.
Q: What is the warranty coverage? A. According to the manual (section 11): 2 years on firebrick and case, 1 year on elements and thermocouple, 5 years on controller electronics. Labor not included. Section 9: Frequently Asked Questions (From the Manual’s
Q: How do I convert to Celsius? A. On TAP controller: go to Settings (plug icon) > Units > Switch to °C. On Rampmaster: Not possible; use a conversion chart.
Before diving into the manual specifics, it is important to understand what the Evenheat 5320 is. This is a 120-volt, 15-amp kiln with an interior chamber roughly 5.25 inches deep, 5.25 inches wide, and 20 inches long (hence the "5320" designation). It is a horizontal tube kiln, originally designed for glass annealing and ceramic testing, but has become legendary in the knife-making industry for heat-treating high-carbon and stainless steel blades.
Because this kiln is often used for precision work (heat treating a $200 knife blade or firing a bespoke pendant), the margin for error is zero. The Evenheat Kiln Model 5320 manual is not a suggestion—it is a survival guide for your projects.
Evenheat no longer lists the 5320 on their current website, but you have three solid options:
