Do not alter the unit heater in any way or damage to the unit and/or severe personal injury or death may occur!
Disconnect all power and gas supplies before installing or servicing the heater. If the power disconnect is out of sight, lock it in the open position and tag it to prevent unexpected application of power. Failure to do so could result in fatal electric shock, or severe personal injury.
Ensure that all power sources conform to the requirements of the unit heater, or damage to the unit will result!
Follow installation instructions CAREFULLY to avoid creating unsafe conditions. All wiring should be done and checked by a qualified electrician, using copper wire only. All gas connections should be made and leak- tested by a suitably qualifi ed individual, per instructions in this manual. Also follow procedures listed on "Gas Equipment
Use only the fuel for which the heater is designed (see rating plate). Using LP gas in a heater that requires natural gas, or vice versa, will create risk of gas leaks, carbon monoxide poisoning, and explosion.
Conversion to a fuel other than that listed on the rating plate is permitted only with a factory supplied, ETL approved conversion kit.
Make certain that the power source conforms to the electrical requirements of the heater.
Do not depend upon a thermostat or other switch as sole means of disconnecting power when installing or servicing heater. Always disconnect power at main circuit breaker as described above. Failure to do so could result in fatal electric shock.
Special attention must be given to any grounding information pertaining to this heater. To prevent the risk of electrocution, the heater must be securely and adequately grounded. This should be accomplished by connecting a ground conductor between the service panel and the heater.To ensure a proper ground, the grounding means must be tested by a qualified electrician.
