1. Choose the unit location.
2. Place the unit into position and secure it to the floor
with 1¹⁄₂” (38mm) screws, or nails. The holes to
secure the unit to floor are located just behind the
access door grille on the left and right side 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”
(13 mm), 5/8” (16 mm), or 3/4” (19 mm). (Fig. 4)
5. Screw through the slotted holes in the drywall strip
and into pre-drilled holes in fireplace side. Measure
from face of fireplace to the face of the drywall strip
to confirm the final depth.
Check fireplace to make sure it is levelled
and properly positioned.
