Replacing and Installing
A newly installed gas water heater will have some air in the gas
line. It may take several attempts to light the pilot. Follow the
lighting procedure on the label. Make sure the gas supply valve has
been turned on.
Newer water heaters are more energy efficient and have much
smaller pilot lights than older models. You may have to darken the
room and look carefully through the sight glass to see the
If you are replacing the water heater yourself, get an
Installation Kit. Most replacements require the use of common
plumbing tools, pipe joint compound or Teflon® tape approved for
potable water and fuel gas. If your house has copper pipes,
consider flexible connectors and compression fittings. For
non-professionals, compression fittings are easier to use than
soldering copper pipe. If you do plan to solder copper pipe, be
aware that the water heater connections may contain non-metallic
parts which can melt. Don't solder copper pipes directly attached
to the water heater. Instead, solder about a foot of pipe to an
adapter first, then attach the adapter and solder the pipe at least
one foot from the water heater's inlet and outlet connections (and
cool the adapter with wet rags).
The Installation Instructions have a comprehensive Check List.
Make sure you have successfully completed each step before lighting

IMPORTANT - Read and follow the printed
Installation Instructions that came with your water heater. The
printed Instructions and product labels contain model-specific
information, important warnings and safety notices. If you lack the
necessary skills to install, troubleshoot or repair the water
heater, get help from a qualified person.
Newly installed gas water heaters are normally trouble free. The
most common problem with gas water heaters is lighting the pilot
the first time. Newer water heaters are more energy efficient and
the smaller pilot light can be hard to see.
Leaks are almost always due to faulty water supply
The first time a gas water heater is started up, it will produce
condensation. You may hear dripping sounds or see a small puddle of
water in the drain pan. Condensation is normal and will go away
once the water heater has reached its normal operating
