To determine the safest and most efficient location for your appli-
ance, you must take into consideration the following guidelines:
1. The location must allow for proper clearances (see Clearances,
next column).
2. Consider a location where heat output would not be affected
by drafts, air conditioning ducts, windows, or doors.
3. A location that avoids the cutting of joists or roof rafters will
make installation easier. Figure 2 shows a plan view of a few
common locations.
Flush installations are recommended where living space is
limited or at a premium, and since the space required to enclose the
appliance would be located beyond an outside wall, this would also
reduce the cutting of joists, roof rafters, and such. Check local codes
for any restrictions.
Projected installations can extend any distance into the room. A
projection may be ideal for a new addition on an existing, finished wall.
Corner installations make use of space that may not normally be
used and provides a wider and more efficient range for radiant heat
transference.
Internal wall installations provide a discreet option for room
separation and can also be ideal as an addition to an existing wall.
