ing it ideal for emergency backup heat.

brick liner. As with all concrete liners, this liner
may develop slight cracks when exposed to heat.
These cracks will not affect the performance of
the fireplace or vent-free gas logs.
OUTSIDE AIR kIT ACCESSORY
The optional AK4 air kit provides additional out-
door air to improve burner efficiency and reduce
build-up of condensation in the living space. Fol-
low the instructions included with the air kit.
