The thermocouple is suppressed during heater ignition, and when that stops it shuts off the fuel flow if heater ignition should fail. I have never seen a checklist that called for cabin heat before engine start, but I suppose if one engine quits and then starts dribbling fuel it could get ignited anywhere such as at the heater.

I'm again confused by this though: "I suppose if one engine quits and then starts dribbling fuel it could get ignited anywhere such as at the heater."
Huh?

A running engine isn't going to drip as much but I guess it could. Would probably catch on fire all by itself if that happens. Any fuel leak is a fire hazard obviously. I do not think I would preheat a light twin cabin using a Janitrol like that, but if you did it then it must have worked out ok.

I've not known of one (or a Southwind, for that matter) to be wired through, say, and oil pressure switch. They'd all fire up with just the master on, if that's what you wanted. This is on Seneca IIs, PA30s, and Aztecs (and one Jeep). Overall I found them very reliable.
Goodman now owns the Janitrol name; there's no mention of it on their website that I can find. Stewart-Warner still mentions combustion heaters; OP might contact them for a manual. The Southwind operated similarly to the Janitrol, IIRC.
