The Fireplace models covered in this manual
are Direct-Vent sealed combustion vented gas
fireplace heaters designed for residential ap-
plication. Direct-Vent appliances operate with
the combustion chamber completely isolated
from the inside atmosphere. All air for com-
bustion is brought in from the outside and
exhaust gases are vented through the same
direct vent, vent system.

without the use of matches. This system
provides continued service in the event of a
