The appliance and its gas connection must be leak tested before placing
the appliance in operation.
The appliance and its individual Shut-off valve shall be disconnected
from the gas supply piping system during any pressure testing of
that system at test pressures in excess of 1/2 pound per square inch
(3.5 kPa). It shall be isolated from the gas supply piping system by
closing its individual manual Shut-off valve during any pressure testing
of the gas supply piping system at test pressures equal to or less than
1/2 pound per square inch (3.5 kPa).
Connecting the gas piping to the gas control valve of the water heater
can be accomplished by either of the two methods shown in Figures
18 and 19.

FLEXIBLE CONNECTOR.

BLACK IRON PIPE TO GAS CONTROL.

SEDIMENT TRAPS

Contaminants in the gas lines may cause improper operation of the gas
control valve that may result in fi re or explosion. Before attaching the
gas line be sure that all gas pipe is clean on the inside. To trap any
dirt or foreign material in the gas supply line, a drip leg (sometimes
called a sediment trap) must be incorporated in the piping. The drip leg
must be readily accessible. Install in accordance with the "Gas Piping"
section. Refer to the current edition of the National Fuel Gas Code,
ANSI Z223.1/NFPA 54.
A sediment trap shall be installed as close to the inlet of the water heater
as practical at the time of water heater installation. The sediment trap
shall be either a tee fi tting with a capped nipple in the bottom outlet or
other device recognized as an effective sediment trap. If a tee fi tting is
used, it shall be installed in conformance with one of the methods of
installation shown in Figures 18 and 19.

FILLING THE WATER HEATER

Never use this water heater unless it is completely full of water. To prevent
damage to the tank, the tank must be fi lled with water. Water must fl ow
from the hot water faucet before turning "ON" gas to the water heater.
To fi ll the water heater with water:
1. 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.
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 fi lling of the tank, allow air to exit by opening the
nearest hot water faucet. Allow water to run until a constant fl ow is
obtained. This will let air out of the water heater and the piping.
4. Check all water piping and connections for leaks. Repair as
needed.

BLOWER ASSEMBLY INSTALLATION

SEQUENCE OF INSTALLATION
1. This power vented water heater comes with the blower assembly
installed.
2. After the unit is set in place, make sure the blower assembly is still
mounted securely and the air intake screen of the blower assembly
is installed in the dilution air opening. Also make sure the drain port
of the rubber boot vent adapter is capped off. Lastly, make sure there
is no damage to the blower.
3. Make sure there is no packing material in the discharge of the blower
or the intake of the dilution air restrictor, see Figure 21.
