I have a non-controversial question for you ES and IV guys and maybe
  even you 2 seater guys.  I am not getting much air flow through my heat
  system on my ES.  My fresh air pickup to the heat muff is on the left
  air intake on the bottom of the baffling (horizon piece as opposed to
  the verticle piece).  Where are you getting your fresh air input to your
  heat muff?  Any other suggestions?

Chat,

 

I draw heat muff input air from the bottom of the forward part of the baffling, too.  If you are using the Lancair cabin heat valve (1.5") the most common mistake is connecting the heat muff hot air to the wrong leg. 

 

1. Valve control arm should be on the engine side of the firewall.

 

2. Hot air goes into the side opening.

 

3. Waste hot air goes out the forward opening (no cabin heat, valve closed) and is usually dumped into the lower cowl area.

 

4.  Cabin heat air exits the aft opening inside the cockpit when the valve is opened.
