Venting continued-
This water heater must be connected to a lined masonry chimney or venting
system approved by local codes or ordinances. The vent connector used to
attach the draft diverter outlet to the chimney or approved vent must be of the
same diameter as the draft diverter outlet or larger. For proper venting in
certain installations, a larger vent connector may be needed. Consult venting
tables in ANSI standard (Z223.1-or latest edition), National Fuel Gas Code
and CAN/CGA (B149.1 or B149.2-latest editions) Natural Gas and Propane
Installation Code, or local code officials for proper application for your area.
Combustion Air Supply
Provide adequate air for combustion and ventilation. An insufficient supply of
air will cause recirculation of combustion products resulting in air
contamination that may be hazardous to life. Such a condition often will result
in a yellow, luminous burner flame, causing carboning or sooting of the
combustion chamber, burners and flue tubes with possible damage to the
water heater.
When an exhaust fan is installed in the same room with a heater, sufficient
openings for air must be provided in the walls. Undersized openings will
cause air to be drawn into the room through the chimney, causing
recirculation of combustion products.
WARNING
Liquefied petroleum gases/propane gas are heavier than air and will
remain at floor level if there is a leak. Basements, crawl spaces, closets
and areas below ground level will serve as pockets for accumulation of
leaking gas. Before lighting, smell all around the appliance area for gas.
Be sure to smell next to the floor.
IF YOU SMELL GAS:
• Do not try to light any appliance.
• Do not touch any electric switch; do not use any telephone in your
building.
• Immediately call your gas supplier from a neighbor’s telephone.
Follow the gas supplier’s instructions.
• If you cannot reach your gas supplier, call the fire department.
DO NOT OPERATE APPLIANCE UNTIL LEAKAGE IS CORRECTED!
IMPORTANT
The flow of combustion and ventilating air must not be obstructed.
• Do not block or in any way restrict jacket air inlet slots located at the
bottom front of the water heater.
