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.\u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"d-faq-item\"\u003e\n    \u003cdiv class=\"d-q\"\u003eWhat are the installation requirements for the DD9?\u003c\/div\u003e\n    \u003cdiv class=\"d-a\"\u003eThe 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.\u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"d-faq-item\"\u003e\n    \u003cdiv class=\"d-q\"\u003eDo I need to purchase kiln furniture separately?\u003c\/div\u003e\n    \u003cdiv class=\"d-a\"\u003eYes, 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.

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.\u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"d-faq-item\"\u003e\n    \u003cdiv class=\"d-q\"\u003eHow is the Olympic kiln warranty activated?\u003c\/div\u003e\n    \u003cdiv class=\"d-a\"\u003eOlympic 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.
