Common questions
Can this kiln run on both natural gas and propane? Yes. The Olympic 23 Raku is convertible between natural gas and propane. The kiln can be factory-configured for either fuel type, and conversion kits are available if you need to switch fuel sources. Natural gas typically provides more consistent BTU delivery for long firing sessions, while propane offers greater portability. Contact us to specify your preferred fuel type when ordering.
What are the gas supply requirements for this kiln? For natural gas operation, you'll need a dedicated gas line with adequate pressure (typically 7-14 inches water column) and sufficient BTU capacity to reach Cone 10 temperatures. For propane, a standard tank with appropriate regulator is required. The exact BTU rating and supply line sizing should be determined by a licensed gas technician based on your facility's specifications. All gas installations must comply with local codes and regulations.
Does this kiln come with kiln furniture? No, kiln furniture (shelves and posts) is sold separately. Raku firing often requires specialized furniture that can withstand rapid temperature changes and thermal shock. We recommend high-temperature shelves rated for Cone 10 and sized to fit the 23.375″ diameter chamber. Contact us for furniture kit recommendations specific to raku firing techniques.
What installation and ventilation requirements should I plan for? The Olympic 23 Raku requires outdoor installation or a well-ventilated indoor space with proper exhaust ventilation, as gas kilns produce combustion byproducts. You'll need clearance from combustible materials as specified in the owner's manual, typically 18-36 inches on all sides. The kiln should be installed on a non-combustible surface with the included stand. A licensed gas technician must perform the gas connection, and installation must meet all local fire and building codes.
How is the one-year warranty activated? Register your kiln with Olympic Kilns within 30 days of delivery to activate the one-year limited warranty. The warranty covers manufacturing defects in materials and workmanship but does not cover damage from improper installation, misuse, or normal wear components like burner parts. Warranty service is only valid when the kiln is purchased through an authorized Olympic dealer like Peach State Pottery.

Common questions about this kiln

Still stuck? Call or text (470) 264-3563 and talk it through with a real person.

Is freight delivery included in the price?

No. Kiln prices do not include freight, and we do not quietly build it into the product price. Freight is charged at a flat rate based on your delivery address and is shown at checkout. Liftgate service is included when it is needed, and standard delivery is curbside. You can estimate your delivered cost with the ZIP code tool above the Add to Cart button.

Can I return this kiln if it is not right?

Return requests can be submitted within 30 days of delivery. The kiln needs to be in its original packaging, in new and resellable condition, and approved before it is sent back. A restocking fee may apply. Completing the manufacturer's recommended first test firing does not by itself make a kiln non-returnable, so you can confirm it works before you commit. Full terms are on our Returns page.

What electrical supply do I need for this kiln?

The Specifications tab on this page lists this model's voltage, amperage, required breaker size and NEMA plug configuration. Most 240V kilns need their own dedicated circuit fitted by a licensed electrician, while many 120V models run from a standard household outlet. If you are unsure what your space can support, call or text (470) 264-3563 before ordering.

Does this kiln come with a warranty?

Yes. This kiln carries the Olympic Kilns manufacturer warranty. Coverage length, what is included and any registration deadline are listed in the Specifications tab on this page. We are an authorized Olympic Kilns dealer, which is a condition of warranty coverage on most kiln brands.

What comes with the kiln, and what do I need to buy separately?

The What's Included tab on this page lists exactly what ships with this kiln. Most kilns need shelves, posts and kiln wash before your first firing, and these are not always included. A vent is recommended for indoor installations. Any add-ons available for this model are shown above the Add to Cart button.
