Fellow listers,



I'm getting ready to install my heater vents on the firewall.



The way I read it, the instructions say 'inlet down'.  This means that when you're not using the heater, the hot air is being blown up behind the engine instead of down towards the cowl exit area.



Did I miss something?  Does it matter?  I would think inlet up.......Did they instruct it the other way for a reason?



Pictures of how folks have already done it would be appreciated.  Also, If you did it one way and didn't like it......why?

Ralph,

I used the -7 upgrades on the -6A and it has the heater vavle waste exit on the left side.   Not sure I'd want to spill oil from the filter into the heater valve...which would happen if it was exit up.

Ralph,

I put them in with the inlet (actual cockpit outlet) down and have no 

problem. I think it might be more of a problem, reversed, with the heat 

being trapped up into avionics and instruments. I think it also would 

impede the flow away from your possibly cold feet and the cockpit. I 

also installed small tributary tubes that work as defrost, which 

contrary to some advice, I find necessary in NE Ohio.

I installed mine with the inlet up so that unused hot air would exit down at the cowl outlet and it works fine.  we have relatively mild temps here in Norcal but I can only crack my heater vent open before it begins to overheat the cabin.
