VENTILATION AIR

Ventilation Air From Inside
Building

This fresh air would come from an adjoining
unconfined space. When ventilating to an
adjoining unconfined space, you must pro-
vide two permanent openings: one within
12" of the ceiling and one within 12" of the
floor on the wall connecting the two spaces
(see options 1 and 2, Figure 2). You can also
remove door into adjoining room (see op-
tion 3, Figure 2). Follow the National Fuel
Gas Code, NFPA 54/ANS Z223.1, Section
5.3, Air for Combustion and Ventilation
 for
required size of ventilation grills or ducts.

 WARNING: Rework work-

sheet, adding the space of the
adjoining unconfined space. The
combined spaces must have
enough fresh air to supply all
appliances in both spaces.

Ventilation Air From Outdoors

Provide extra fresh air by using ventilation
grills or ducts. You must provide two per-
manent openings: one within 12" of the
ceiling and one within 12" of the floor.
Connect these items directly to the outdoors
or spaces open to the outdoors. These spaces
include attics and crawl spaces. Follow the
National Fuel Gas Code, NFPA 54/ANS
Z223.1, Section 5.3, Air for Combustion and
Ventilation
 for required size of ventilation
grills or ducts.

IMPORTANT:

 Do not provide openings for

inlet or outlet air into attic if attic has a
thermostat-controlled power vent. Heated air
entering the attic will activate the power vent.
