SELECTING LOCATION
To determine the safest and most efficient
location for the fireplace, you must take into
consideration the following guidelines:
1. The location must allow for proper clear-
ances (see Figure 2).
2. Consider a location where the heat output
will not be affected by drafts, air condition-
ing ducts, windows or doors.
3. A location that avoids the cutting of
joists or roof rafters will make installation
easier.
4. If an outside air kit is to be installed, ac-
cessibility to outside combustion air must
be considered. This can also be achieved
through a vented crawl space in some
cases (see Optional Outside Air Kit on
page 6).
The typical installation for a (V)3612ST is a
projected installation which allows you to ex-
tend the fireplace any distance into the room.
A projection may be ideal for a new addition
on an existing, finished wall.
