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 .04% (400 parts
per million) in the air can be fatal. When making high re or low
re adjustments, CO levels must be monitored using a ue gas
analyzer such that a CO level of no more than 150 ppm is exceeded
at any time during operation.
Adjusting the “low re oset” or the “main ow restrictor” in small
increments can result in a signicant 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 ue gas analyzer.
This water heater must be installed by a licensed plumber, licensed
gas tter, and/or qualied installer / service technician. Improper
installation and/or operation can cause a potentially hazardous

death, and will void the warranty.
The manufacturer cannot anticipate every circumstance that
might involve a potential hazard. Each installation has its own
specialized characteristics, requirements, and possible hazards.
Therefore, all possible incidents are not included in these

damage, or any other damaging condition that might aect the
operation of the unit. Have the water heater checked by a qualied
technician before resuming operation.
Do not power up the unit unless the gas and water supply valves
are fully opened. Make sure the fresh air intake port and exhaust
gas port are open and functional.

This water heater provides a overheat shutdown limit. In the event
the water heater water exceeds the set point of the control limit, the
cuto will trip and the water heater will shut down. Certain local
codes require additional temperature limits. In addition, certain
types of systems may operate at temperatures below the minimum
set point of the limit provided with the water heater. Contact the
manufacturer for additional overheat controls.
