If the appliance is to be elevated above ﬂoor level, a solid continuous platform must be constructed below the appliance.

Note: The framed depth, 16 in. (406 mm) from a framed wall, must always be measured from a ﬁnished surface. If a wall covering such as drywall is to be attached to the rear wall, then the 16 in. (406 mm) must be measured from the drywall surface. It is important that this dimension be exact.

Headers may be in direct contact with the appliance top spacers but must not be supported by them or notched to ﬁt around them. All construction above the appliance must be self-supporting, DO NOT use the appliance for structural support.

Pre-installation Notes

The ﬁreplace may be positioned and then the framing built around it, or the framing may be constructed and the ﬁreplace positioned into the opening.

Usually, no special ﬂoor support is needed for the ﬁreplace, however, to be certain:

1. Estimate the total weight of the ﬁreplace system and surround materials such as brick, stone, etc., to be installed.

2. Measure the square footage of the ﬂoor space to be occupied by the system, surrounds and hearth extensions.

3. Note the ﬂoor construction, i.e. 2 x 6’s, 2 x 8’s or 2 x 10’s, single or double joists, type and thickness of ﬂoor boards.

4. Use this information and consult your local building code to determine if you need additional support.

Side Nailing Flanges

The ﬁreplace should be secured to the side framing members using the unit's nailing ﬂanges - two at the top and bottom on each side of the ﬁreplace front. See Figure 7. Use 8d nails or their equivalent.

Floor Nailing Tabs

Fireplace may be anchored to ﬂoor. Bend down two anchor tabs (one on each side) located at the base of the ﬁreplace and secure to the ﬂoor by nailing with 8d nails or equivalent

(Figure 8).

Figure 7

Note: Some units only have one anchor tab on each side.
