Why Upgrade from Mechanical Relays to Solid-State Relays?
Mechanical Relays, which come standard on most kilns have internal moving parts which over time wear out and need to be replaced. Kiln manufacturers recommend you replace your mechanical relays approximately every 2 years. Solid-state relays have no moving parts and last far longer than standard mechanical relays and offer far better temperature control during hold times. Since solid-state relays also have no moving parts to wear out, they NEVER need to be replaced. You will notice that solid-state relays are silent. The only sound you will hear is just the reassuring hum of the heating elements. So, this factory upgrade saves you potential downtime from having to wait for new relays to arrive, potential over-fires from relays sticking in the closed position, potential aggravation from having to learn how to remove and replace the mechanical relays yourself. We think this upgrade is well worth the cost and will save you time and aggravation over the life of your kiln.
NOTE*** This kiln is delivered fully assembled. No assembly is required on site. This kiln will require private freight company delivery as it cannot be sent through regular (LTL- less than truckload) shipping as it will require the entire truck. The carrier is responsible for transporting the freight but not for unloading it. Large capacity kilns 20 cubic feet and larger require the customer to have a forklift that can move the kiln from the truck to the desired location. If you do not have access to a forklift, check the internet or yellow pages for small moving companies that can take the freight off the freight carrier and move the freight to the desired location. Give any prospective mover a physical description of the kiln and its weight, and inform them that it is designed to be picked up with a truck and a forklift only. It is your responsibility to move the freight from the truck to its place of use.

Here's a Sample DPF Firing schedule:
Note: The specific firing schedule may vary depending on the DPF manufacturer, its condition, and the desired level of cleaning. Always consult the DPF manufacturer's guidelines for the most accurate and safe procedures.
Here's a general firing schedule using multiple segments in Fahrenheit:
Segment 1: Pre-Heat
Temperature Range: 150°F to 350°F
Duration: 10-15 minutes
Purpose: Gradually warms up the DPF to prevent thermal shock.
Segment 2: Soot Oxidation
Temperature Range: 350°F to 800°F
Duration: 30-60 minutes
Purpose: Oxidizes soot particles in the DPF.
Segment 3: High Temperature Cleaning
Temperature Range: 800°F to 1000°F
Duration: 30-60 minutes
Purpose: Removes any remaining soot and ash.
Segment 4: Cool Down
Temperature Range: 1000°F to 150°F
Duration: 30-60 minutes
Purpose: Gradually cools down the DPF to prevent thermal shock.
Additional Considerations:
Oxygen Supply: Ensure adequate oxygen supply during the cleaning process.
Monitoring: Monitor the DPF's temperature and pressure throughout the cleaning cycle.
Repeat Cycles: If necessary, repeat the cleaning process until the desired level of soot removal is achieved.
Professional Assistance: For complex or heavily clogged DPFs, consider consulting a professional for cleaning.
Remember: This is a general schedule. Always refer to the DPF manufacturer's specific guidelines for the most accurate and safe cleaning procedures.
For those who need a specific DPF Firing schedule to enter based on the above guidelines:
Segment 1: 250F p/h to 350F - HOLD 15min
Segment 2: 350F p/h to 800F - HOLD 60 min
Segment 3: 350F p/h to 1000F - HOLD 60 min
Segment 4: off
Do not open the oven door until you are under 200F.
