Filling the Water Heater
_, CAUTION I
Never usethis water heater unlessit iscompletelyfilledwith
water. Toprevent damageto the tank, the tank must befilledI
with water. Water must flow from the hot water faucet
beforeturn ng ON gasto the water heater.
For properventing in certain installations,a larger diameter vent
pipe may be necessary. Due to great variances in installations,
unforeseeableby the manufacturer of the water heater, you must
consult your gas company to aid you in determining the proper
venting foryourwater heater fromthe vent tablesin the latestedi-
tion of the National FuelGas Code ANSI Z223.1, alsoreferredto
asNFPA 54.
To fill the water heater with water:
• Close the water heater drain valve by turning the handle to
the right (clockwise). The drain valve is on the lower front of
the water heater.
• Open the cold water supply valve to the water heater.
NOTE: The cold water supply valve must be left open
when the water heater is in use.
• To insure complete filling of the tank, allow air to exit by
opening the nearest hot water faucet. Allow water to run
until a constant flow is obtained. This will let air out of the
water heater and the piping.
• Check allnew water piping for leaks. Repairas needed.

high enough to properly open thermally operated vent
dampers. Thiswouldcausespillage of fiuegasesand maycause
carbon monoxide poisoning.
