OPERATING YOUR WATER HEATER
Lighting Instructions
Read and understand these directions thoroughly before
attempting to light or re-light the pilot. Make sure the
viewport is not missing or damaged. (See Figure 23)
Make sure the tank is completely filled with water before
lighting the pilot. Check the data plate near the gas control
valve/thermostat for the correct gas. Do not use this water
heater with any gas other than the one listed on the data
plate. If you have any questions or doubts, consult your gas
supplier or gas utility company.
FOR YOUR SAFETY READ BEFORE LIGHTING
TO TURN OFF GAS TO APPLIANCE
A. This appliance has a pilot which is lighted by a
piezoelectric igniter. When lighting the pilot, follow these
instructions exactly.
B. BEFORE LIGHTING smell all around the appliance area
for gas. Be sure to smell next to the floor because some
gas is heavier than air and will settle on the floor.
WHAT TO DO IF YOU SMELL GAS:
v Do not try to light any appliance.
v Do not touch any electrical switch; do not use any
phone in your building.
v Immediately call your gas supplier from a
neighbor’s phone. Follow the gas supplier’s
instructions.
v If you cannot reach your gas supplier, call the fire
department.
C. Use only your hand to push in or turn the gas control
knob. Never use tools. If the knob will not push in or
move by hand, don’t try to repair it, call a qualified service
technician. Force or attempted repair may result in a fire
or explosion.
D. Do not use this appliance if any part has been under
water. Immediately call a qualified service technician to
inspect the appliance. Water heaters subjected to flood
conditions or anytime the gas controls, main burner or
pilot have been submerged in water require replacement
of the entire water heater.
E. DO NOT USE THIS APPLIANCE IF THERE HAS BEEN AN
IGNITION OF VAPORS. Immediately call a qualified service
technician to inspect the appliance. Water heaters
subjected to a flammable vapors ignition will show a
discoloration on the air intake grid and require
replacement of the entire water heater.
2. Turn the gas control knob clockwise to the “OFF”
position.
1. Turn the temperature dial counterclockwise to its
lowest setting.
WARNING:
If you do not follow these instructions exactly, a fire or explosion
may result causing property damage, personal injury or loss of life.
