STANDOFFS
Before you begin, you must install the standoffs.
Install the two sides standoffs and the top one like
showned on (Figure 3).
LOCATION
Your Onyx AP fireplace may be installed without any
special floor reinforcement.
WARNING: If this fireplace is not properly installed,
a house fire may result. For your safety, follow the
installation directions and heed the minimum
clearances.
The enclosure walls can be framed using any suitable
materials (2 x 4 studs, plywood, gypsum board, etc.).
See (Figure 5) for dimensions. Normally, framing will be
set back to allow the sheeting to be level with the front of
the fireplace.
When framing in the header (directly above the fireplace), DO NOT bring any combustible material lower than the
top of the stand-off.
1. Note the location of floor and roof joists. Choose a location which does not require cutting the joists. Note the
location of doors and windows in relation to the fireplace and chimney on all floors of the house.
