Gas heater gurus... Some input please?

I'm at the final stage of install. My main question is, I made a section of 1.5" pipe for the heater exhaust. It is very close to the tank, is this of any concern? Should I wrap it or does it not get hot enough to be a potential problem? My secondary question is, after it passes through the bulk head / firewall area and gets level with the floor, is it really necessary to have it come all the way out back? I hate to have a pipe dangling underneath of a flat bottom car. I know, fumes. If my floor (new) is sealed up should it be an issue to have a simple dump tube?

The normal gas heater exhaust pipe runs pretty close to the tank. Evidently that's not a problem. The end of the pipe is about even with the passenger's feet (except under the floor of course.) Just a suggestion: Why don't you add your car type and year to a signature so responders don't have to guess what you're working on? It would sure be a help. Thanks.

I know next to nothing about the Corvair gasoline heater, but I do have some reference material (attached) which may prove to be useful if you don't already have copies.

That's a good idea. Thanks!

Yes I have those documents. I even have the dealership install manual. Thank you bbodie.

On the FC's the fuel supply and overflow lines run VERY close to the exhaust pipe. The corporate lawyers would have a stroke if anything like that was attempted today!

Hahaha ok I guess I'm safe then. I must say that after bolting the heater up, I have a crack in my firewall about 3 inches long going into the cowl. Must be thing there. It was pretty rusty... Seam sealer to the rescue!
