installing chimney for propane stove

I have tried this thread before, but got off topic answers to stove installation that I didn't ask. Looking for information on running it thru the fiberglass room of my airporter style short bus.

I don't need help with running propane and installing millboard as a heat shield.

It is most likely that I will run the chimney thru the roof as this is a venting propane stove. So, wonder what you have done with your bus that has a propane heater or fireplace? I think my stove pipe is 6"

Proper double wall venting, a jig saw, some butyl caulk and one of these:

Dektite Red Silicone Metal Roof Pipe Flashing


Make the roof hole a couple inches bigger than the pipe for a thermal gap. I used some steel L-brackets to secure my chimney in the center of the hole.

It'll work anywhere you go as long as you're above the water line.

Terminate your chimney with one of these to keep the rain out:

This is my setup:


Check the manual for your propane appliance, but you may not need to get much height for appropriate draft. You typically need to get the chimney above the highest point on your roof to prevent back draft.

Also, you probably don't need the cat..

I solved my problem by putting up the fireplace on craigslist and will be buying a vent free stove, no stove pipe, no problem.

An unvented propane heater, I presume? They work, but if you thought rain on the outside of the bus could be a problem, just wait until you have rain forming inside the bus Propane creates lots of moisture when burned. Also be sure to buy a CO alarm.

These stoves are 99.0% efficient and a similar one kept us warm for about ten years. They give off a slight amount of water vapor and I always keep a window cracked for ventilation. Never had the rain experience you speak of and I live in the rainy Tacoma area, but just because it is not a problem for me, doesn't mean it isn't for you esp if you don't have cross ventilation. BTW, I have always been religious about cracking a window open and having air exchange. People die all the time In RVs from Oxygen starvation.
