Statement of Intended Use:

The 

Burntech

 Vent-Free Universal Masonry Fireplace is a 

modular refractory masonry unit designed for 

fi

 eld assembly. 

The 

fi

 rebox 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 

fi

 rebox.

These 

fi

 replaces are not intended to serve as 

a primary heat source, rather, the 

fi

 replace was 

expressly created as a supplemental source of 
heat.

Burntech

 

Vent Free Fireplace 

is Designed 

for Use Only with any Vent free decorative gas 
log sets meeting standard ANSI Z21.11.2
