Gas Fireplace Inserts
Vented fireplace inserts are designed as gas log configuration
within a metal cabinet that can be installed (only) in existing masonry
and factory-built fireplaces. A metal surround seals off the space between
the unit and the fireplace opening. Conventionally vented inserts may
be vented with Type B vent or approved single wall liner through the
chimney. Direct vent inserts may be vented with colinear or coaxial
direct vent.
