Venting continued-
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
Z223.1.73.4e and 7.8a, b 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 (
25.4 cm
) above expected
snowfall level to prevent blockage of vent termination.
Vent pipes serving power vented 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 codes.
WARNING
Risk of carbon monoxide poisoning or fire due to joint separation or
pipe breakage.
This water heater must be properly vented and connected to an approved
vent system in good condition.
DO NOT
operate water heater with the
absence of an approved vent system. A clean and unobstructed vent system
is necessary to allow noxious fumes that could cause injury or loss of life to
vent safely and will contribute toward maintaining the water heater’s
efficiency. The acceptance of the venting system is dependent upon full
compliance with these installation instructions.
Venting system
must not
pass through rated fire separations.
The venting system must be free to expand and contract. This venting
system
must be
supported in accordance with these instructions.
Clearance to combustibles for all venting pipes and terminals
For installations in the US
0” minimum
For installations in Canada
Refer to vent pipe and terminal
manufacturer’s installation instructions
for clearances to combustibles
DO NOT place insulation or other materials in the required clearance spaces
between the venting to combustible material unless otherwise specified.
