Filling the Water Heater
To fill the water heater with water:
1. Close the water heater drain valve by turning the han-
dle to the right (clockwise). The drain valve is on the
lower front of the water heater.
2. 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.
3. 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.
4. Check all new water piping for leaks. Repair as needed.
Check the venting system for signs of obstruction or deterio-
ration and replace if needed.
The combustion and ventilation air flow must not be
obstructed.
All vent gases must be completely vented to the outdoors
of the structure (dwelling). Install only the draft hood pro-
vided with the new water heater and no other draft hood.
Vent pipes must be secured at each joint with sheet metal
screws.

There must be a minimum of 6 inches clearance between
single wall vent pipe and any combustible material. Fill
and seal any clearance between single wall vent pipe and
combustible material with mortar mix, cement, or other
noncombustible substance. For other than single wall, fol-
low vent pipe manufacturer’s clearance specifications. To
insure a tight fit of the vent pipe in a brick chimney, seal
around the vent pipe with mortar mix cement.
Installing the New Water Heater (cont’d)
VENT PIPE INSTALLATION
For proper venting in certain installations, a larger diameter
vent pipe may be necessary. Due to great variances in
installations, unforeseeable by the manufacturer of the
water heater, you must consult your gas company to aid
you in determining the proper venting for your water heater
from the vent tables in the current edition of the National
Fuel Gas Code ANSI Z223.1, also referred to as NFPA 54.

CAUTION
Never use this water heater unless it is completely full of
water. To prevent damage to the tank, the tank must be
filled with water. Water must flow from the hot water
faucet before turning “ON” gas to the water heater.
WARNING
To insure proper venting of this gas-fired water heater, the
correct vent pipe diameter must be utilized. Any additions
or deletions of other gas appliances on a common vent
with this water heater may adversely affect the operation
of the water heater. Consult the local gas utility if any
such changes are planned.
WARNING
Failure to have required clearances between vent piping
and combustible material will result in a fire hazard.
WARNING
The vent pipe from the water heater must be no less
than the diameter of the draft hood outlet on the water
heater, and must slope upward to the chimney at least
1 ⁄
4
inch per linear foot.
WARNING
Obstructed or deteriorated vent systems may present
serious health risk or asphyxiation.
WARNING
The water heater with draft hood installed must be con-
nected to a chimney which terminates to the outdoors.
Never operate the water heater unless it is vented to
the outdoors and has adequate air supply to avoid risks
of improper operation, explosion or asphyxiation.
WARNING
VENT DAMPERS - Any vent damper, whether it is operated
thermally or otherwise must be removed if its use inhibits
proper drafting of the water heater.
Thermally Operated Vent Dampers: Gas-fired water heaters
having thermal efficiency in excess of 80% may produce a
relatively low flue gas temperature. Such temperatures may
not be high enough to properly open thermally operated
vent dampers. This would cause spillage of flue gases and
may cause carbon monoxide poisoning.
Vent dampers must bear evidence of certification as com-
plying with the current edition of the American National
Standard ANSI Z21.68 (ANSI Z21.66 & 67, respectively,
cover electrically and mechanically actuated vent dampers).
Before installation of any vent damper, consult the local
gas utility for further information.
