Mantel Clearances:
Vent free firebox models must use the hood
supplied with the firebox, or one of the optional hood kits
available for each model. If a combustible mantel is installed,
it must meet the clearance requirements detailed below.
Grate Clearance:
The minimum clearance between the front legs
of the grate and front edge of the firebox is 2".
Leave at least 36" clearance from the front of the firebox.
Any vent-free Gas Log Heater must be “For use with approved
ANSI Z21.11.2 unvented room heater.”
Follow and complete the installation instructions of the gas log set
and the requirements of this firebox.
Check all fittings for leaks before lighting the gas log set.
In planning the installation for the firebox, it is necessary to
determine where the unit is to be installed and whether optional
accessories are desired. Gas supply piping should also be planned
at this time.
A gas shut off must be in this line.
