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, also referred to as NFPA 54.
SEDIMENT TRAP
A sediment trap shall be installed as close to the inlet of the
water heater as practical at the time or 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.
GAS METER SIZE - CITY GASES ONLY
Be sure that the gas meter has sufficient capacity to supply the
full rated gas input of the water heater as well as the
requirements of all other gas fired equipment supplied by the
meter. If the gas meter is too small, ask the gas company to
install a larger meter having adequate capacity.
Connecting the gas piping to the gas control valve of the water
heater can be accomplished by either of the two methods shown.

OPERATING INSTRUCTIONS FOR MODEL 100-400 BEFORE
OPERATING THE WATER HEATER
1. Review the installation and instruction manual before turning on the
electric power and gas supply to the water heater, to safeguard
against a possible dangerous malfunction of the water heater.
2. The electrical supply to this water heater must NOT be turned on
before the tank is completely full of water, the gas supply is available,
and the venting system is completely installed.
3. Because there is normally a certain amount of air in a gas line when a new
water heater has been installed, it may be necessary to re-sequence the
water heater several times before it lights on the initial start-up.
4. Turn on electrical and gas supply to the water heater. Turn the toggle switch
on. Turn the gas cock knob completely on. Go to "Operational Sequence" and
follow the operation of the water heater to insure it is operating properly.
AN ODORANT IS ADDED TO THE GAS USED
BY THIS WATER HEATER.
FOR YOUR SAFETY
IF YOU SMELL GAS:
1. Do not try to light any appliance.
2. Do not touch any electrical switch; do not use any phone in
your building.
3. Immediately call your gas supplier from a neighbor's phone.
Follow the gas supplier's instructions.
4. If you cannot reach your gas supplier, call the fire department.
These models are equipped with an electrically operated venting system
and an intermittent ignition system. For the pilot to light and the burner to
come on, the water heater's thermostat must call for heat. Then the
system will begin sequencing, each section proving itself before actual
pilot ignition takes place.
