Operation and Installation Warnings
To avoid serious injury or death, read, understand and
follow all the precautions listed here.
DANGER
Vapors from flammable liquids will explode and can
cause a fire, resulting in personal injury or death. The
water heater has a burner that can come on at any
time and ignite vapors. DO NOT use or store flammable
liquids around the water heater.
Improper venting can cause a build-up of carbon monoxide.
Breathing carbon monoxide can result in brain damage or
death. DO NOT operate the water heater unless it is properly
vented to the outside and has an adequate fresh air supply
for safe operation. Inspect the exterior exhaust gas outlet port and
fresh air inlet port on a regular basis to ensure they are functioning
properly.
A concentration of carbon monoxide as small as 0.04% (400
parts per million) in the air can be fatal. When making high
fire or low fire adjustments, CO levels must be monitored
using a flue gas analyzer such that a CO level of no more
than 400 ppm is exceeded at any time during operation.
Adjusting the “low fire offset” or the “main flow restrictor” in
small increments can result in a significant increase in CO
concentration. To avoid serious injury or death, DO NOT
make any adjustments to the gas valve without monitoring
the exhaust gases with a fully functional and calibrated flue gas
analyzer.
WARNING
The Hubbell water heater must be installed by a licensed plumber,
licensed gas fitter, and/or professional service technician. Improper
installation and/or operation can cause a potentially hazardous
situation, which, if not avoided, could result in serious injury or
death, and will void the warranty.
Proper care is your responsibility. Carefully read and
understand the Operation Information in this manual before
operating the Hubbell water heater.
Make sure you know the location of the gas shut-off valve
and how to operate it. Immediately close the gas shut-off
valve if the water heater is subjected to fire, overheating,
flood, physical damage, or any other damaging condition that
might affect the operation of the unit. Have the water heater checked
by a qualified technician before resuming operation.
