Olympic's large capacity gas car kilns provide flexibility and easy loading in a range of sizes for business, school or the professional potter. Heavy, solid construction inures low fuel consumption for many years of service. The design also gives the kiln operator the capability to have multiple cars with items ready to fire once a load has completed the firing process. So as one car is removed from the firing chamber, another can be placed on the rails and fired in the kiln chamber.

  • Olympic Downdraft (DDs) Gas Kilns are front-loading and built of either fiber or brick and board insulation.
  •  Multiple venturi burners give even heat distribution to cone 10 on low-pressure propane and natural gas with minimal maintenance.
  •  Gas flow and reduction are easily controlled from the front of the kiln.
  •  An ignition system with thermocouple safety shut-off, gas pressure gauge, heavy welded hinges and an adjustable supporting door wheel are standard.

  Olympic designs are durable and efficient, but a special feature of all their commercial kilns is the easy disassembly for repair or maintenance when it becomes necessary.

Venting Gas Kilns
Proper ventilation is required when firing a gas kiln. Gas kilns fired outside may not require a vent but any gas kiln fired indoors will require ventilation. When purchasing vents it is often best to choose a local HVAC or sheet metal manufacturer, or Olympic Kilns can build one for you. Vent dimensions need to be round or square in a cone shape and the bottom of the vent needs to be larger than the outside diameter of the kiln. Diameter at the top of the vent needs to be 10” discharging into a nonflammable exhaust pipe determined by building conditions or local codes
Olympic DownDrafts Construction
he DownDraft kiln’s exhaust, as well as intake, is at the bottom. DownDrafts require a chimney or stack to induce enough draft to pull in fresh air for combustion. Olympic DownDrafts fire to cone 10, 2350° F and can be built of brick or fiber. Fiber walls allow the kiln to heat up and cool down faster than brick walls, which are designed for a slower cooling down and heating up firing.

The frames of the Olympic downdraft gas car kilns are built of heavy angle iron and metal tubing. Kiln walls are 4 ½” insulating brick with 1” ceramic fiberboard and 1” air space created by the tube frame. The exterior of the downdraft kilns are durable stainless steel. Fiber and brick DownDrafts are built with double insulated floors, consisting of brick and ceramic fiberboard. The additional strength and insulation enables the kiln to fire at high temperatures, and to maintain temperatures, without damage or deterioration. The roofs of the Olympic DownDrafts are designed with bolt in pyro-block modules for energy efficiency and easy repairs. The DownDraft car kilns have a heavy gauge iron track for rolling the kiln floor and door in and out of the kiln chamber.

Olympic DownDrafts are built with high efficiency venturi burners that are underneath the kiln chamber and have an option of being built on the side of the kiln chamber. Forced air burners are an available option. Olympic DownDraft gas kilns come fully assembled ready to fire and are shipped with peephole plugs, instruction manual, and warranty card. One-year Limited Kiln warranty.
