Like everyone has said before, the instructions are hard to understand. It is in English, but not very understandable. Even so, keep the manual, it does have some info that will help me (hopefully) figure it out. I opted to buy different fuel line, and also didn't use the \"seal\" in the install. I also used high temp sealant for the exhaust, and plan on wrapping the exhaust too. The only issue I ran into was with the tank. Two days after it started leaking slowly, so took it apart and discovered the issue. The surface on the tank next to the o ring was not flat, so I filed it down to level. No problems now. It took about three starts for the heater to start. I didn't prime the fuel line, I let it prime itself, and no issues. Really pumps out the heat!
