3.4. VENTILATION
HOOD
Proper ventilation hood operation is very important for the correct operation of this appliance and the
safety of personnel. The ventilation hood should be inspected at the time of installation of this
appliance to insure that it will operate properly in conjunction with the appliance. A regular schedule
of examination, in accordance with ANSI/NFPA 96 latest edition and/or local codes must be followed.
Your new gas appliance must have proper ventilation to function safely and properly. Exhaust gas
temperatures can reach as high as 1000°F (538 °C). Therefore, it is very important to install a fire
safety system. Your ventilation system should be designed to allow for easy cleaning. Frequent
cleaning of the ventilation system and the appliance will reduce the chances of fire. Additional
information can be obtained from CSA International, 8501 East Pleasant Valley Rd., Cleveland, OH
44131.
CAUTION
Excessive ventilation causes drafts, which will interfere with the operation of the appliance. Leave
at least 18 inches of open space between the flue opening and the intake of the exhaust hood.
CAUTION
Ensure that your ventilation system does not cause a down draft at the appliance’s flue opening.
Down drafts will not allow the appliance to exhaust properly and will cause overheating which
may cause permanent damage. Damage caused by down drafts will not be covered under
equipment warranty. NEVER allow anything to obstruct the flow of combustibles or ventilation
exiting the appliance flue.
