Common questions
Can I convert this kiln between natural gas and propane?
The DD9 is configured at the factory for either natural gas or propane – you must specify which fuel type you need when ordering. Converting between fuel types after purchase requires replacing burner orifices and adjusting gas pressure settings, which should only be performed by a qualified gas kiln technician. If you anticipate needing to switch fuel types, consult with Peach State Pottery before ordering.
What are the installation requirements for the DD9?
The DD9 requires a dedicated gas line sized appropriately for the kiln's BTU rating, proper gas pressure regulation, and a ventilation system that exhausts combustion gases safely to the exterior. The installation must comply with local building codes and gas appliance regulations. We strongly recommend hiring a licensed gas fitter and kiln installation specialist to ensure safe operation. The kiln also needs a stable, level, non-combustible floor surface with adequate clearance from walls and combustible materials.
Do I need to purchase kiln furniture separately?
Yes, kiln furniture is not included with the DD9 and must be purchased separately. For a 15 cubic foot chamber, you'll need multiple 30″ × 25″ shelves and an assortment of posts in various heights to create efficient stacking configurations. We recommend starting with at least 6-8 shelves and a full post set. Contact Peach State Pottery for a furniture kit recommendation based on your specific production needs.
What is the difference between downdraft and updraft gas kilns?
In a downdraft kiln like the DD9, heat enters at the top or mid-level, circulates downward through the ware, and exits through a flue at the bottom. This creates more even heat distribution from top to bottom compared to updraft kilns, where heat enters at the bottom and rises directly upward. Downdraft kilns typically produce more consistent results across all shelf levels, making them preferred for production work where uniformity is critical.
How is the Olympic kiln warranty activated?
Olympic Kilns provides a one-year limited warranty that must be registered within 30 days of delivery. The warranty is only valid when purchased through an authorized dealer like Peach State Pottery. Register your kiln directly with Olympic Kilns after delivery using the serial number and purchase documentation. The warranty covers manufacturing defects but does not cover damage from improper installation, misuse, or normal wear components.

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.
