Return air question

New postby Marc M on Sun Aug 25, 2013 1:35 am

Hey Jerry,
just need clarification. Does this below exception underlined, say that you "can" have a return air near a fireplace etc...?

2010 CMC 311.3 Prohibited Source. Outside or return air for a heating
or cooling air system shall not be taken from the following
locations:


Exception: Such openings when used for a heating or
cooling air system in a dwelling unit shall be permitted
to be reduced to not less than 50 percent of the required area, provided the balance of the required return air is taken from a room or hall having not less than three (3) doors leading to other rooms served by the furnace.
(5) A closet, bathroom, toilet room, or kitchen.
(6) From rooms or spaces containing a fuel-burning appliance
therein.Where such room or space serves as source
of return air.
Exceptions:
(1) This shall not apply to fireplaces, fireplace appliance,
residential cooking appliance, direct vent
appliance, enclosed furnaces, and domestic-type
clothes dryers installed within the room or space
.
