Before Beginning the Installation
Read these instructions carefully before beginning the
installation of this Vent-Free fireplace. Also read the gas
log appliance manufacturer’s literature regarding sizing
and suitability for installation into this Enclosure prior to
installation.
Statement of Intended Use:
The Mason-Lite Vent-Free Universal Masonry Fireplace is a
modular refractory masonry unit designed for field assembly.
The firebox is constructed using pre-cast, interlocking
refractory blocks. The blocks are then secured to each other
using Mortar. The system includes all parts necessary for the
assembly of a complete masonry vent-free decorative gas log
enclosure.
In addition to the basic enclosure, a standard 1-1/8” thick,
high temperature refractory brick is required to line the interior
of the firebox.
These fireplaces are not intended to serve as a primary
heat source, rather, the fireplace was expressly created as a
supplemental source of heat.
The MASON-LITE is Designed for Use Only with any Vent
free decorative gas log sets meeting standard ANSI Z21.11.2
Vent free decorative gas log sets meeting standard ANSI
Z21.11.2, are supplied by others and are limited to any listed
vent-free gas-fired log sets with heat input ratings up to
40,000 Btu/hr.
