5. Spread the slit open and slip the insulation over the
cold water (inlet) pipe. Apply gentle pressure along
the length of the insulation to ensure it is fully seated
around the pipe. Also, ensure the base of the insulation
is fl ush with the water heater. Once seated, secure the
insulation with duct tape, electrical tape, or equivalent.
6. Repeat steps 4 and 5 for the hot water (outlet) pipe.
7. Add additional sections of pipe insulation as needed.
HIGH ALTITUDE INSTALLATION
Breathing carbon monoxide can cause brain damage or death.
Always read and understand instruction manual.
• For operation above 10,100 ft.
a high altitude orifice must be
installed.
• Contact a qualified installer or
service agency.
Breathing Hazard - Carbon Monoxide Gas
WARNING
This heater is approved for operation up to 10,100 ft.
without alteration.
Failure to replace standard orifi ce with a high altitude
orifi ce when installed above 10,100 ft. could result in
improper and inefficient operation of the appliance,
producing carbon monoxide gas in excess of safe limits,
which could result in serious injury or death. Contact
your gas supplier for any specifi c changes which may be
required in your area.
GAS PIPING
• Do not use water heater with
any gas other than the gas
shown on the rating plate.
• Excessive pressure to gas
control valve can cause serious
injury or death.
• Turn off gas lines during
installation.
• Contact qualified installer or
service agency.
Fire and Explosion Hazard
WARNING
Explosion Hazard
Have a qualified technician make sure that the L.P.
gas operating pressure does not exceed 14" water
column.
Failure to do so can result in death, explosion, or
fire.
WARNING
Make sure the gas supplied is the same type listed on the
model rating plate. The inlet gas pressure must not exceed
14” w.c. for natural gas and propane gas. The minimum
inlet gas pressure shown on the rating plate is that which
will permit fi ring at rated input.
All gas piping must comply with local codes and ordinances
or with the “National Fuel Gas Code”, ANSI Z223.1/
NFPA 54. Copper or brass tubing and fi ttings (except tin
lined copper tubing) should not be used.
If the gas control valve/thermostat is subjected to
pressures exceeding 1/2 psi, the damage to the gas
control valve/thermostat could result in a fi re or explosion
from leaking gas.
If the main gas line shut-off serving all gas appliances is
used, also turn “OFF” the gas at each appliance. Leave
all gas appliances shut “OFF” until the water heater
installation is complete.
A gas line of suffi cient size must be run to the water heater.
Consult the current edition of “National Fuel Gas Code”,
ANSI Z223.1/NFPA 54 and your gas supplier concerning
pipe size.
There must be:
• A readily accessible manual shut-off valve in the gas
supply line serving the water heater, and
• A sediment trap ahead of gas control valve/thermostat
to help prevent dirt and foreign materials from entering
the gas control valve/thermostat.
• A fl exible gas connector or a ground joint union between
the shut-off valve and gas control valve/thermostat to
permit servicing of the unit.
Be sure to check all the gas piping for leaks before lighting
the water heater. Use a soapy water solution, not a match
or open fl ame. Repair and retest as required. When
fi nished, rinse off soapy solution and wipe dry.
