I am still very new to all of this, and this is my first inquiry about installing the Avalon 900PS I just bought today. I still need to learn how it works and bench test it, though I am working on that. Looking ahead to the install.
I can install the vent vertically, but all I have is a hole in the roof, basically, so I would need to buy all the rest. I am looking at the instructions (that are about 20 years old.) It shows a horizontal vent install with 3-inch clearance on the back, three inch pipe through a thimble, and 1 foot extension beyond the exterior wall. Elsewhere, it mentions 4-inch pipe for high elevation.
Question one - does the 1 foot extension beyond the wall still make sense? (changes in code, conventions, etc.)
Question two - does it make any sense to use 4-inch pipe when the whole run will be about two feet? (I am at 8000 feet elevation.)
Question three - the diagram shows a termination with a 45-degree end, which would be about one foot above the interior floor, but obviously outside. Does this assume that the exterior wall would be well above a horizontal surface. In my case, there would be two feet of pipe, the 45 degree downturn, with the discharge one foot above a wood deck. The instructions don't say "no." But that seems weird to me. How hot is the exhaust and does it spit any sparks? It this just a plain old "that is bad."
