WARNING!
The dimensions shown in

are minimum clearances to maintain when
installing this heater. Left and right clearances
are determined when facing the front of the
heater.
Follow these instructions carefully to ensure
safe installation. Failure to follow instructions
exactly can create a fire hazard.
Floor Clearance
— The fireplace may be installed directly
on a combustible floor or a raised platform of an appropriate
height. Do not place fireplace on carpeting, vinyl, tile or
other soft floor coverings. It may, however, be placed on flat
wood, plywood, particle board or other hard surfaces. Be
sure fireplace rests on a solid continuous floor or platform
with appropriate framing for support so that no cold air can
enter from under the firebox. See note below regarding
floor installation with wide contemporary faces.
