Note: The prices shown for the Torchbearer and Raku kilns here include the Ignition Ring with Thermocouple Safety Shut-off
which adds a high degree of safety. We can supply these kilns without the Ignition ring but we feel that for safety's sake these should always be installed. 
The price with out the ignition ring are $300 less for 28" kilns and $250 less for all others.
The ignition system is used to:
■ Light the multiple burner system from
one point
■ Maintain the flame on each burner
■ Re-ignite any burner that may
extinguish
The thermocouple safety shut-off will stop the gas flow if the flame is lost entirely.
