FIREBOx FRAMING
Firebox framing can be built before or after the appliance is set in place. Construct firebox framing following
Figure 2
and the chart below for your specific installation requirements. Refer to
Figure 3
on page 8 for firebox
dimensions. The framing headers may rest on the top of the firebox standoffs. Do not bring headers below top
of standoffs.
Please note: When planning your framing and installation, keep in mind that your gas line will come
in on the right side of the box (as you are facing it) and your electricity will come in on the left side.
The firebox may be installed directly on a combustible floor or raised on a platform of an appropriate height.
When the firebox is installed directly on carpeting, tile,
or other combustible material, other than wood flooring,
the firebox shall be installed on a metal or wood panel
extending the full width and depth of the enclosure.
