PRODUCT FEATURES
OPERATION
This firebox is designed for use with approved ANSI Z21.11.2 deco-
rative type unvented room heaters. (Physical size limitations apply.
Refer to minimum firebox requirements supplied with log heater.) It
requires no outside venting or chimney making installation easy and
inexpensive. When used without the blower, the firebox requires no
electricity making it ideal for emergency backup heat.
OUTSIDE AIR KIT ACCESSORY
The optional AK4 and AK4F air kit provides additional outdoor air to
improve burner efficiency and reduce build-up of condensation in living
space. Follow instructions included with air kit.
REFRACTORY BRICK LINER
Your firebox may feature a concrete refractory 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.
