The location must allow for proper clear-ances (see Clearances).. Consider a location where heat outputwould not be affected by drafts, air con-ditioning ducts, windows, or doors.3. A location that avoids the cutting of joistsor roof rafters will make installation easier.Figure shows a plan view of a few com-mon locations.Flush installations are recommended whereliving space is limited or at a premium, andsince the space required to enclose the ap-pliance would be located beyond an outsidewall, this would also reduce the cutting ofjoists, roof rafters, and such. Check localcodes for any restrictions.Projected installations can extend anydistance into the room. A projection maybe ideal for a new addition on an existing,finished wall.Corner installations make use of spacethat may not normally be used and providesa wider and more efficient range for radiantheat transference.Internal wall installations provide a discreetoption for room separation and can also beideal as an addition to an existing wall.
