Hello. I'm also considering putting a unit in an airstream ('61 22ft in my case), probably a sardine. The trailer has an existing vent that was previously used for a propane hot water heater. The hot water heater was removed before I purchased the trailer, but the vent is still there. It looks to be 3.5 inches. A few questions: Any problem in theory with using a vent originally set up for a hot water heater? Would a stove vent need to be installed differently for any reason? Any problem with narrowing the pipe to 3.5 inch using a connector? The placement I'd like to use would cause me to run the vent at an angle of something like 30 to 45 degrees from horizontal for a distance of about 2 feet. Any foreseen problems with that?
Pipe installed for hot water heaters does not cut it for woodstoves. You will need to use 4" insulated pipe. Send us an email to request the info PDF's.
The pipe "offset" you mention is not a problem. You will need a pair of adjustable elbows. A/NSW
