INSTALLATION INSTRUCTIONS FOR
FLEXIBLE VENT KIT PART NUMBER
239-47813-00
This vent kit is designed to bring all air for combustion from the outside and
vent all the combustion products to the outside when properly installed. This
vent kit should only be used with direct vent water heaters that were
designed for use with this vent kit. Refer to the label on the water heater to
determine if this kit is the correct kit for the water heater that you are
installing. Consult the supplier of the water heater if you are not certain that
this is the correct vent kit. Refer to the information in these instructions and
the instructions provided with the water heater when determining the location
of the vent terminal and water heater.
The vent system must terminate so that proper clearances are maintained as
cited in local codes or the latest edition of the National Fuel Gas Code, ANSI
Z223.1 as follows:
1. Do not terminate near soffit vents or crawl space or other area where
condensate or vapor could create a nuisance or hazard or cause
property damage.
2. Do not terminate the exhaust vent terminal where condensate or vapor
could cause damage or could be detrimental to the operation of
regulators, relief valves, or other equipment.
3. Do not terminate the exhaust vent terminal over public area or
walkways where condensate or vapor can cause nuisance or hazard.
4. The vent shall terminate a minimum of 12 inches (30.5 cm) above
expected snowfall level to prevent blockage of vent termination.
Vent pipes serving direct vent appliances are classified by building codes as
“vent connectors”. Required clearances from combustible materials must be
provided in accordance with information in this manual under LOCATION OF
WATER HEATER and CLEARANCES, and with National Fuel Gas Code
and local code.
WARNING
The vent-air intake system must be properly installed. Failure to properly
install the vent-air intake system could result in property damage,
personal injury or death.
DO NOT install any damaged vent-air intake system components.
Contact the manufacturer of the water heater for replacement parts.
