Conversation: propane preheater
Subject: propane preheater

I don't see anything wrong with running a duct into the cabin. My
plane
(74 warrior) has the battery under the back seat and it must also be
preheated. I run warm air into the cabin from my Red Dragon and prop
up
the bench seat so the air gets to it. By the time I've shut down the
heater, put it away, opened the door and got in, any CO buildup is
gone.


How do you keep the Carbon Monoxide detector from turning black? There
is enough CO in the heated air stream to trigger the detector -- or
don't you have one in the cockpit?
