Larry-
Air intake is a safety issue: you definitely want to get the fresh intake
air from outside the van. That completely closes the combustion loop so that
the entire process-intake, burn and exhaust, are sealed from the air that
you are breathing. There is no opportunity for combustion biproducts to
enter the passenger compartment. Please make sure this is how you install
it.
I've no experience with a side mount, but looking at the pictures and
recalling what I can about the interior of air cooled buses, that is mounted
on an angled surface, I think, not vertically as you are thinking about. .
The photo is not very good.
I'd really check the manual or the factory on this, because while I have
never seen the actual burner in my propex, and it may be that it is designed
so that the direction of the flame is important. Hot air rises.
What if the unit is installed on the side, but was designed to be on its
bottom only. The burner flame maybe be pointing toward the heat exchanger,
and they may count on the principle of hot air rising to get the most heat
transfered to the exchanger. It may work, but it also may be less efficient.
I'd really check with the factory on this one, or someone that knows a lot
about the units.
Good luck

Subject: [Syncro] Propex Furnace Install Question
Volks,
Two questions on the Propex 1600 Furnace install.
Question One:
This unit has three vent/intake hoses.
Heat Output
Fresh Air Input
Exhaust Output
This question concerns the Fresh Air Intake Hose.
All the installs I have seen (under rear seat or nxt to water tank) seem to
route the Air Input Hose/Vent to the outside.
One Example:

<http://home.attbi.com/~aaronanderberg/Exhaust_Detail.html>
Can't this hose be routed inside the van, rather than externally?
Could we use recirculated air for this, rather than outside air and
elimanate the need to cut another hole in the floor of the Van?
Question Two:
This heater can't be mounted vertically or upside down ... but I believe it
is OK to mount it on its side as depicted in this photo?

<http://www.bluebird-type2.co.uk/how%20to%20propex.htm>
I'm thinking of mounting mine nxt to the water tank like the first link, but
on its side, fastened to the wall between the closet and water tank. Anyone
see a problem with this?
Hitting the Trail Soon ... REALLY!
