Breathing Hazard - Carbon Monoxide Gas
o High altitude orifice must be installed for
operation above 7,700 feet (2,347 m).
- Contact a qualified installer or service
agency
Breathing carbon monoxide can cause brain damage or
death. Always read and L4nderstand instruction manual

Fire and Explosion Hazard
" Contaminants in gas lines can
cause fire or explosion
• Clean all gas piping before
installation.
• InstaN drip leg in accordance with
NFPA 54
Water heaters covered in this manual have been tested and
approved for installation at elevations up to 7,700 feet (2,347 m)
above sea level. For installation above 7,700 feet (2,347m),
the water heater's Btu input should be reduced at the rate of 4
percent for each 1,000 feet (305 m) above sea level which
requires replacement of the burner orifice in accordance with
the National Fuel Gas Code ANSI Z22&1/NFPA 54. Contact
your local gas supplier for further information.
Failure to replace the standard orifice with the proper high
altitude orifice when installed at elevations above 7,700 feet
(2,347 m) could result in improper and inefficient operation of
the appliance, producing carbon monoxide gas in excess of
the safe limits. This could result in serious injury or death.
Contact your local gas supplier for any specific changes that
may be required in your area.
Firs and Explosion Hazard
, Use joint compound or tape
corn patible with propane,
Leak test before operating
heater.
, Disconnect gas piping and
shut-off valve before pressure
testi ng syste m.
Use pipe joint compound or teflon tape marked as being
resistant to the action of petroleum (Propane [LR]) gases,
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 19 and 20.
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 al! 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 Z223.1INFPA 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 19 and 20.
