Fire
and
Explosion
Hazard
•
Contaminants
in
gas
lines
can
cause fire or explosion.
•
Clean
all
gas
piping
before
installation.
•
Install
drip
leg in accordance
with
NFPA54.
Contaminants
in the gas lines may cause
improper
operation
of the gas
control valve
that may result
in fire 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 fitting with a capped
nipple
in the bottom
outlet or
other device
recognized
as an effective
sediment
trap. If a tee fitting
is
used,
it shall
be installed
in conformance
with
one of the methods
of
installation
shown in Figures
18 and 19.

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.
4.
