Where Should You Put Your Kiln?
Kilns are vital for potters, glass workers, and some metal workers, so selecting and installing one requires careful consideration. One of the most crucial aspects is determining the right location for your kiln. Placing a kiln in an unsuitable environment or improper installation can lead to serious accidents. This article aims to guide you in selecting the best location for your kiln and highlights key considerations for placing it effectively in your space.
Location of the Kiln
When setting up a kiln in your home, several location options are available, each with its own considerations. Garages and basements are popular choices due to their typically sturdy flooring and generous space. These areas often provide a good balance of accessibility and safety. Another option is an unheated outbuilding, such as a shed, which can offer isolation from living spaces. However, if you choose this route, be aware that cold kiln temperatures can affect electric controllers. In such cases, you may need to warm up the space before use to ensure proper functioning of the kiln's computer. Regardless of the location you choose, always prioritize safety and follow local building codes and manufacturer guidelines.

Room Dimensions and Air Circulation
Before you buy your kiln, you’ll need to know the space of where you place your kiln. This is crucial for both safety and efficiency. Avoid small, enclosed areas like closets or compact utility rooms, as these can lead to dangerous heat buildup. Instead, opt for a spacious area that allows for proper heat dissipation and air circulation.
While specific clearance requirements may vary depending on the kiln model and local regulations, a general guideline is to maintain at least 12 - 18 inches of clear space between the kiln and the nearest walls. This space not only enhances safety but also provides room for ventilation and storage of ceramic ware on steel shelves. If you're operating multiple kilns, aim to keep them at least 12 inches apart to prevent heat accumulation. It's also crucial to keep the kiln area free from flammable materials, including shipping supplies. For added safety, consider using non-combustible materials like cement board or masonry tile on walls near the kiln. Always consult your local building codes and the kiln manufacturer's instructions for specific requirements tailored to your situation and kiln model. Keep in mid that most kilns only have a 6ft cord, making placement near the receptacle important. The longer the electricity must travel to the kiln, the less efficient the kiln will be. Proper planning of your kiln space ensures a safe and efficient firing environment.
What Walls Are Best For Your Kiln?
Ideal kiln placement involves a room with a window or a place to vent hot air out of the room. This configuration facilitates proper venting, which is crucial for safe kiln operation. A motorized vent system, similar to those used for clothes dryers, can be installed to expel fumes directly outside through any exterior wall. If your kiln room is entirely surrounded by interior walls, you'll need to route the venting system through either the ceiling or floor to reach the outdoors. When planning wall materials near the kiln, consider heat-resistant options like cement board or masonry tile. Always consult local building codes for specific requirements regarding wall materials in proximity to high-heat appliances.
Flooring For Your Kiln
The floor beneath and around your kiln requires careful consideration due to the significant heat emitted from the kiln's base. It's essential to place the kiln on a non-combustible surface that can withstand high temperatures without damage. Concrete or sturdy ceramic tiles are excellent choices. Avoid weaker materials like thin tiles, linoleum, carpet, or wood, as these can be damaged or pose fire risks. If a suitable non-combustible floor isn't available, you can create a safe surface using concrete pavers at least two inches thick. These pavers should extend a minimum of 12 inches beyond the kiln's outer diameter to ensure adequate heat protection. For added safety, consider installing a heat-resistant pad designed specifically for kilns beneath the unit.
Proper Venting System
Proper ventilation is critical when operating a kiln, regardless of whether it's gas or electric. Without adequate venting, heat and potentially harmful gases can accumulate in confined spaces, posing serious health and safety risks. A well-designed venting system directs these byproducts outside, where they can safely dissipate. You have several options for venting, including overhead hood systems or integrated kiln vents. Integrated vents not only remove fumes but can also help the kiln cool more quickly after firing. Your choice of venting system will depend on factors such as the kiln's location, size, and your specific firing needs. Consult with a kiln professional or HVAC specialist to determine the most effective venting solution for your setup. A full venting system is not always necessary for firing bisque or for glass work, and most metals.
Electrical Capacity
Before purchasing a studio kiln, it's crucial to assess your building's electrical capacity. Start by determining your available voltage. If you're unsure how to measure this, contact your power company or hire a licensed electrician for an accurate assessment. For commercial spaces, it's important to know whether your power supply is single-phase (two hot wires and one grounding wire) or three-phase (three hot wires and one grounding wire). Most household power is single phase and only some commercial sites are 3-phase. It’s always safe to ask and not assume what your setting will have. Ensure your electrical system can handle the kiln's amperage requirements, as older buildings might require costly upgrades to support a new kiln. Additionally, consider future expansion when planning your electrical capacity. It's also important to verify that the kiln can physically fit through doorways and hallways to reach its intended location. Consult with your kiln distributor for precise exterior dimensions and electrical specifications.
Heat Safety when Using a Kiln
Kiln safety is paramount due to the extreme temperatures involved in firing. During operation and cooling, kiln surfaces become dangerously hot and can cause severe burns. Establish and maintain a safety perimeter around the kiln, keeping children, pets, and unauthorized personnel away from the area during firing and cooling cycles. Remove all flammable items from the vicinity of the kiln, including curtains, plastics, paper, and other materials that could ignite or melt when exposed to high temperatures. Avoid using hair sprays or other aerosols near the kiln, as these can be flammable. Consider installing heat-resistant barriers or warning signs around the kiln area. Always use appropriate personal protective equipment, such as heat-resistant gloves and safety glasses, when working with or near the kiln. Regularly inspect your kiln and its surrounding area to ensure continued safe operation.

What About Fire Sprinklers?
In the commercial setting of a kiln room, make sure sprinkler heads in the ceiling are positioned away from the kiln. There have been instances where schools were flooded because a sprinkler head located directly above a kiln activated the fire alarm. To avoid this, consider using a higher temperature sprinkler head in the kiln room or one that detects smoke instead of heat. Additionally, installing a vent hood can help reduce the temperature around the kiln.
Conclusion
Installing a kiln can be quite challenging due to the numerous precautions and specific requirements involved. However, once you navigate these complexities and complete the installation, the process should become much smoother. While occasional issues may arise, such as needing to replace parts, reaching out to the manufacturer can provide valuable assistance for acquiring replacements or resolving problems. Once your kiln is operational and functioning optimally, the initial effort and stress will prove worthwhile.
