SW4024 and Pizzo Ignitors [RE-wrenches]

[matthew tritt]

Scott,

My bet is that the genset isn't powerful enough to both run the ignitor and
charge batteries at the same time. A bigger generator is the answer (if your
customer doesn't want to buy another stove!) I find old stoves for my
clients all the time which use a standing pilot or a match! (The old ones
are better anyway.
;-)_

Good luck

Matt
