Air Supply & Ventilation
The following notes are intended to give general guidance. For detailed recommendations, refer to the applicable
codes in the Country, State, County and City of installation.
Do not obstruct the flow of combustion and ventilation air.
Proper ventilation is critical for optimum performance. The area in front of, around and above the appliance must be
kept clear to avoid any obstruction of the flow of combustion and ventilation air. Adequate clearance must be
maintained at all times in front and at the sides of the appliances for Servicing and proper operation.
The ideal method of ventilating gas fired equipment is the use of properly designed canopy that should extend six
inches (152mm) beyond all sides of the appliance (s) and six feet six inches (1981mm) above the floor. Information
on the construction and installation of ventilating hoods may be obtained from the standard for "Vapor Removal
from Cooking Equipment,"
NFPA No. 96
(latest edition), available from the National Fire Protection Association,
on their web site: http://www.nfpa.org/.
A strong exhaust will create a vacuum in the room. For an exhaust vent to work properly, replacement air must be
equal to the amount of air exhausted. An imbalance between exhaust and replacement air can cause degradation in
the appliance’s performance. Strong exhaust fans in this hood or in the overall air conditioning system can produce a
slight vacuum in the room and/or cause air drafts, either of which can interfere with pilot or burner performance and
can also be hard to diagnose. Air movement should be checked during installation; if pilot or burner outage problems
persist, make-up air openings or baffles may have to be provided in the room.
NOTICE:
In the Commonwealth of Massachusetts all gas appliances vented by either mechanical systems or
ventilation hoods shall comply with
248 CMR
interlocking requirements.
