Hi Kevin,

I'm basically taking your advice since Espar is being unresponsive now that I've bought the replacement furnace. I do have two questions for you based on your experience.

First, did any on the heaters you installed have a separate self-regulating feed-pump (in addition to the metering pump) ? If so, did you wire them in parallel ? There are no pinouts that I see for a separate feed-pump when a gravity-tank is not used.

Second, the power coming to the furnace is supplied by heavy cables going through a 40 Amp fuse. The power going into the new Airtronics goes through a 5 Amp fuse and what looks like 12 ga. wires. Do you know if the Airtronic uses a spark igniter rather than a glow-plug or why the power requirement is just 1/8th of what it was in the old heater ?

Thanks,



-Sven
