  • What You Need to Know Before Buying a Kiln

    Purchasing a kiln might seem overwhelming at first, but the team at Olympic Kilns provides all of the information and support you need from start to finish. Follow the steps below and you’ll be firing up your new kiln in no time!

    Choosing a Kiln Model

    Before all else, do some research to determine which model kiln is best for you. In order to make that decision, consider these three important factors:

    1. The dimensions (width and height) of the pieces you plan to fire
    2. The temperature range needed for those pieces
    3. The type of power and electrical wiring that is available where you plan on putting your kiln

    With these three things in mind, browse our electric, gas and glass firing kilns. You can also find a variety of kilns in our catalogues, which list complete pricing and size information. If you’re not sure which catalog to start with, take a look at the comprehensive price list for detailed specifications on all types of kilns.

    If you would like help choosing the right kiln, be sure to call us at 770-967-4009.

    Purchasing a Kiln

    Once you have decided which kiln is best for you, you can order it directly from our online store. Select the kiln you would like and choose any accessories or additional options. From there you can add the customized kiln to your cart and complete the checkout process. Alternatively, you can contact an Olympic Kilns dealer found on the Distributors page.

    Fill out the warranty registration form to apply for a warranty on your kiln.

    Receiving your Kiln

    Olympic Kilns packages shipments so that they will not be damaged during delivery. The carrier is responsible for getting the kiln to you, but not for unloading it and transporting it to its intended destination.

    If you order a large kiln that requires a loading dock and/or forklift, ensure that you have access to the required equipment. If you do not have access to a forklift or other tools needed to unload the kiln, contact a local moving company to assist you.

    For more details on receiving your kiln, read our receiving guide.

    Locating and Installing your Kiln

    For installation instructions for your specific model, choose your kiln model and click “More Info.” You can also read more about installing electric kilns, updraft gas kilns and downdraft gas kilns via our onsite resources.

    Though each model will vary, there are some general rules you should follow when installing your kiln:

    • Check the dimensions of entryways to ensure that the kiln can fit into the room. If not, contact us to see if we can make modifications to the kiln before it is ordered and built.
    • Allow enough space between the wall and your kiln to walk around it in case maintenance is required.
    • Remove all flammable materials such as curtains, plastics, etc. from the area around the kiln.
    • Ensure there is proper ventilation. Gas kilns in confined areas need an exhaust hood vented to the outside of the building.
    • If the kiln is outside, keep it under a roof and/or water-resistant tarp to keep moisture from the kiln.
    • Use sheet metal or non-flammable material to shim the legs when leveling the kiln.
    • Place the kiln on a concrete floor to avoid heat damage.

    Operating and Maintaining your Kiln

    The Olympic Kilns website has a wealth of resources available to kiln owners. Read through the operating manual that corresponds to your kiln to confirm that you fire safely and correctly. If you experience issues with your kiln, contact a trusted repair technician.

    If you have any questions throughout the process, we will be happy to help. Contact us or call us at 770-967-4009.



  • How to Safely Install an Electric Kiln

    Installing an electric kiln can seem like a complex process, and if done incorrectly, can greatly increase the risk of fire. In this article, we will discuss three easy tips that will help you safely install your electric kiln and avoid common mistakes.

    Proper Location

    An electric kiln must be installed in a dry, large room. Most electricians recommend that you place the kiln between 4 and 50 feet from the breaker box. The closer the kiln is to the breaker box the better, but it must be at least 4 feet away to prevent the kiln from tripping the breakers.

    Another factor to consider when ensuring a proper location is the flooring. Do not install a kiln on flammable floorings such as carpet or wood. Concrete is the recommended flooring but tile or laminate can also suffice. While tile and laminate can be used, concrete is the better choice because it provides a solid foundation.

    Proper Wiring

    A kiln cannot be safe, or operate effectively, without correct wiring. For this reason, you should have an experienced electrician wire the kiln for you. Here are few wiring tips that you can use to double check that the wiring is done correctly.

    • Make sure the electrician does not use aluminum wire. Aluminum wire cannot handle heat from the kiln and can cause fire. Copper wire is the recommended wire to use.
    • Make sure the outlet supports the voltage and has the correct phase power. Installing a shutoff box is also a recommended precaution.
    • For Kiln models with wall plug-ins, the outlet needs to be above the kiln so that the wire hangs down.
    • Periodically check all wiring for corrosion and damage. Due to the extreme heat conditions, the wires are put under intensified stress and need to be checked regularly.

    Proper Ventilation

    Kilns should be installed in a room with an exterior wall so that it can be properly ventilated. Motorized vents should be inserted through the exterior wall to remove fumes from the air and release them outside.  In addition to the motorized vents, the kilns should be placed no closer than 3 feet apart to spread the heat out more evenly across the room.

    With these helpful tips and precautions, you are on your way to installing a safer kiln. You can also read more about electronic wall units, relay schematic, thermocouple replacement and other helpful information.  Please contact us with any additional questions.
