Mantels

Depending on the width of the mantel it may be in- stalled higher or lower from the combustion chamber opening. This also applies to the distance between the mantel leg (if installed) and the ﬁreplace. Refer to Fig- ures 3a and 3b for correct mounting heights and widths for combustible mantels and mantel legs.

Noncombustible mantels and legs may be installed at any height above the appliance opening.

When using paint or lacquer to ﬁnish the mantel, such paint or lacquer must be heat resistant to prevent discoloration.

Hearth Extension

A hearth extension in front of heater is recommended

but not required.

Planning

Planning the installation is an important ﬁrst step: it will save time and money later in the actual installation. In planning the installation, consider:

1.Where the heater will be located.

2.All components needed to complete the project.

Mounting the Heater

The heater should only be mounted on the following surfaces:

•A ﬂat combustible (burnable) surface.

•A raised wooden platform.

•A concrete block or other solid object placed be- neath each of the four corners of the heater.

To mount the heater:

1.Choose unit location.

2.Place unit in position and secure to ﬂoor with 1¹⁄₂" screws, or nails. The holes to secure the unit to the ﬂoor are located just behind the bottom louvre on the left and right hand side of the unit.

3.Frame in heater with a header across the top. It is important to allow for ﬁnished face when setting the depth of the frame.

4.Attach heater to frame using adjustable frame drywall strips (located behind access door for shipping). Preset depth to suit facing material (adjustable to 1/2" , 5/8" or 3/4" depths). (Fig. 4)

5.Use existing screws in side of unit to attach drywall strip. Measure from face of heater to face of drywall strip to determine ﬁnal depth. (Fig. 4)

Framing

Framing can take place before or after the heater is set in place. The framing should be positioned to accom- modate the wall covering and facing material. Framing material should be 2x4 or heavier. Framing headers may rest on top of heater. (Refer to Page 4, Figures 1

and 2 for heater and framing dimensions.)

Insulating for Cold Climates

When a heater is installed in a chase or an outside wall, the enclosure should be insulated like any other wall of the home. Insulation should be installed under the heater and on the inside of the exterior walls. (Fig. 5)

NOTE: Insulating for cold climates is strictly a recom- mendation and not a requirement.
