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. 6)
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. 6)

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 3, Figure 1 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. 7)
NOTE: Insulating for cold climates is strictly a recom- mendation and not a requirement.
