plenum cap


I am new to business. I have installed a few furnaces, all have been upright with upward air flow. My question is when buying plenums they always ask if I need a cap..Are the caps used if the are air flow changes direction at the out end of the plenum? The few that I have installed all had the duct work right above the furnace. No such thing as a silly question right?
Thanks

plenum cap


A plenum often stops just under the joist, and the trunk then taps off the side/front, or rear of the plenum, so a cap is needed for them.

plenum cap


Thank you for your reply, that's what I thought. So far my few have been straight up. Is it a good idea to always wrap the plenum in insulation? This is in an area of California where the winter is pretty mild.

plenum cap


Only if its in an area that if you have A/C the plenum will sweat. if the furnace is in a utility closet or basement that doesn't get very cold, then leaving it unwrapped will help keep that area a little warm, and no harm is done.
