apparatus.
In a cold climate, do not vent into a masonry chimney that
has one or more sides exposed to the outside. Install a listed
stainlesssteellinertoventtheueproducts.

Combustion/ventilation air openings
Even if combustion air is piped to an (optional) burner
air intake adapter, the boiler room must still have the
minimum air openings listed in Table 2 and described in the
following paragraphs. This is to provide needed ventilation to
keep the burner and appliance cool and to avoid the boiler
room developing negative pressure.
 ThecombustionairopeningsMUSTbesizedbasedonthe
total input of all appliances in the room.
Check appliance manual and applicable codes for required sizing/design/
placement of combustion/ventilation air openings. You can use the follow-
inggeneralguidelines,takenfromNFPA31,providedtheymeetalllocal
requirements.

the grilles used, assume free area is 20% of total for wood louvers, or
60% of total for metal louvers.

generally allow enough air infiltration so special provisions will seldom
be required.
