INTRODUCTION
This is a training manual not a job site service manual, nor a parts manual. The intent of this
manual is to train users of PowerVent water heaters. This manual does not assume any particular
user liability, skill level, experience or expertise. The terms and component parts used in this
manual are current manufactured items or vendor provided items used in Rheem PowerVent gas
water heaters, whether natural or liquid petroleum (L.P.). Exercise care when installing and
repairing gas water heaters. Finally, we encourage all users to exercise good common sense and
check your local plumbing, electrical and gas building codes.
SAFETY
FLAMMABLE LIQUIDS AND VAPORS Gasoline, as well as other flammable material and
liquids (adhesives, solvents, etc.), and
vapors they produce are extremely
dangerous. DO NOT handle, use or
store gasoline or other flammable or
combustible materials anywhere near or
in the vicinity of a water heater. The
spark ignition and burner assembly in
the water heater controls can ignite
these vapors. Failure to do so can result
in property damage, bodily injury or
death.
WATER TEMPERATURE ADJUSTMENT
Safety and energy conservation
are factors to be considered when
selecting the water temperature
setting on the thermostat. Water
temperatures above 125
0
F can
cause severe burns or death from
scalding. The chart shown here
may be used as a guide in
determining the proper water
temperature for your home.
