SELECTING LOCATION

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, ﬁn-

ished 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 sepa-

ration and can also be ideal as an addition to an existing wall.
