<DIV><FONT face=Arial size=2>Hi to all,</FONT></DIV>
<DIV><FONT face=Arial size=2>I am doing an energy audit on a museum with a
infrared heater that has the wrong combustion air ductwork(looks like a 4 or 6
inch dryer flex. going through a condition space.) Condensation
caused.</FONT></DIV>
<DIV><FONT face=Arial size=2>I want to specify in my report the actual
corrective measure and I looked through ASHRAE 90.1 2004 and could not find a
section that talked specifically about that?</FONT></DIV>
<DIV><FONT face=Arial size=2>Could someone point me in the right direction?I
spoke with my project manager who indicated the length of run and specific
information from the equipment spec sheet determined size.</FONT></DIV>
<DIV><FONT face=Arial size=2>and I am wanting to recommend at least R6 insulated
duct.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Thanks in advance.</FONT></DIV>
