Is there a way to over-ride the burner safety device for the MK-1
burners (I think that is the correct name... got them from Nils Lou) should
there be an electrical outage during a firing (the safety device operates
on 120 volt a/c)... Is it possible to operate the device (or similar
device) on a DC current? That would give one an option to use a battery in
case of power failure.. This has been a concern of mine and I have never
got a clear answer to this question... I am concern that a power outage
could happen during a glaze fire and a kiln load of pottery could
potentially be ruined...
Take Care... Marshall

>if the sail switch is designed to shut off your burners during power outage
why overide their function rather than remove them and not worry about power
outage?

Depending on the amount of amperage needed you could use a Battery
Backup for home computers. A UPS (uninterrupted power source), cost in
the neighborhood of $250 To $450 depending on the size. This type of
devise would take over supplying the control with electric instantaneous
and could power them for several hour. The length time would depend on
what size you use and the amp draw of the safety controls. If the burner
have blowers it is doubtful this arrangement would work very long. The
other option which is similar to a UPS is using a power inverter which
convert 12 volts D.C. to 120 volts A.C. . This inverter come in a
variety of wattage outputs and the length of time they will run depend on
the number of batteries you use. We have friends that use this type of
arrangement to run there house lights, mixers, and TV for up to a week,
they have no commercial electric. That of course means eight deep cycle
lead acid battery connected in parallel. The electric in our area is so
un-dependable that we have stuck to natural draft burners and Baso type
safety valves.

A typical solenoid and squirrel cage blower will pull about 1.5 amps total.
Not a whole lot, and less than most folks think. Feel free to call if you
have further questions.
