I haven't read about very many people taking this approach for a HERMS system so I'm looking for clarification to see if I've got the concept correct (and I'm not going to suck down CO or blow myself up).
I plan on using high pressure propane with an adjustable regulator. I'd like to use an outdoor grill's electronic ignition system to light my burners (Something like this kit) without a pilot light. If the ignition system does not come with a flame sensor, I'd pick that up separately.
I'll have a computer controller managing the logic, eg, if the gas solenoid is open but the flame sensor reads false then close the solenoid, wait for gas to clear, then begin ignition cycle. The ignition cycle would consist of opening the gas solenoid, sending a signal to the electronic ignitor, and setting a timeout for the flame sensor, shutting down if lighting was unsuccessful.
My questions are: will this work? is this safe/sane? am I missing anything?
