PART 1 – GENERAL SAFETY INFORMATION
INSTALLER – Read all instructions in this manual before installing. Perform steps in the order given.
USER – This manual is for use only by a qualified heating installer/service technician. Have this water heater serviced/inspected by a
qualified service technician annually.
FAILURE TO ADHERE TO THE GUIDELINES ON THIS PAGE AND HAVE THIS WATER HEATER SERVICED/INSPECTED
ANNUALLY CAN RESULT IN SUBSTANTIAL PROPERTY DAMAGE, SEVERE PERSONAL INJURY, OR DEATH.
A. PRECAUTIONS
This water heater is approved for indoor installations only. Clearance to combustible materials: 0” top, bottom, sides and back. Heater
must have room for service: 24” front and 6” sides are minimum recommended service clearances. (A combustible door or removable
panel is acceptable front clearance.) This water heater has been approved for closet installation, and installation on combustible
flooring. Do not install this water heater directly on carpeting.
NOTE: If the heater is exposed to the following, do not operate until all corrective steps have been made by a qualified serviceman:
FIRE
DAMAGE
WATER
Any claims for damage or shortage in shipment must be filed immediately against the transportation company by the consignee.
DO NOT USE THIS WATER HEATER IF ANY PART HAS BEEN SUBMERGED IN WATER. Immediately call a qualified service
technician. The water heater MUST BE replaced if it has been submerged. Attempting to operate a water heater that has been
submerged could create numerous harmful conditions, such as a potential gas leakage causing a fire and/or explosion, or the release
of mold, bacteria, or other harmful particulates into the air. Operating a previously submerged water heater could result in property
damage, severe personal injury, or death.
NOTE: Water heater damage due to flood or submersion is considered an Act of God, and IS NOT covered under product warranty.
