Framing & Finishing
Check the fireplace to make sure it is leveled and properly positioned.
1.Choose the unit location.
2.Place the unit into position and secure it to the floor with 1¹⁄₂” (38mm) screws or nails. Holes for securing the unit to floor are located behind the access door grille on the left and right sides of the unit.
3.Frame in the fireplace with a header across the top. It is important to allow for the finished wall face when setting the depth of the frame.
4.Attach the fireplace to the frame using the adjustable frame drywall strips (located behind the access door for shipping). Preset the depth to suit the facing material of the wall. The strips are adjustable to 1/2” (13mm), 5/8” (16mm) or
3/4” (19mm). (Fig. 5)
5.Screw through the slotted holes in the drywall strip and into predrilled holes in fireplace side. Measure from face of fireplace to the face of the drywall strip to confirm the final depth.
