©2017 Pinnacle Climate Technologies 9 Vent-Free Gas Log Heater User’s Manual
Preparing for Installation (cont.)
If the area in where the heater operates does not meet the required volume for
indoor combustion air, you must provide combustion and ventilation air by one of the
methods described in the NATIONAL FUEL GAS CODE, ANSI Z223.1/NFPA 54, the INTERNATIONAL FUEL GAS
CODE, or applicable local codes.
WARNING
VENTILATION AIR FROM INSIDE A BUILDING
Fresh air comes from a connected unconned space.
You must provide two permanent openings when
ventilating to a connected unconned space, one of
which that’s within 12" of the wall that connects the
two spaces (see options 1 and 2, Fig. 1). You may also
remove the door into the adjoining room (see option 3,
Fig. 1). Follow the National Fuel Gas Code NFPA 54/ANS
Z223.1 for the required size of ventilation grills or ducts.
VENTILATION AIR FROM OUTDOORS
Extra fresh air is provided via ventilation grills or
ducts. You must provide two permanent openings:
one within 12" of the ceiling and one within 12" of the
oor. They must connect directly to the outdoors or
spaces that open to the outdoors. Such spaces may
include attics or crawl spaces. Follow the National
Fuel Gas Code NFPA 54/ANS Z223.1 for the required
size of ventilation grills or ducts.
IMPORTANT: Do not provide openings for inlet or
outlet air into an attic if the attic has a thermostat-
controlled power vent. The power vent will be
activated by heated air that enters the attic. You must
add the space of the connected unconned space
and rework the information on page 8. The combined
spaces must have enough fresh air to supply all
appliances in both spaces.
