FOR YOUR SAFETY
“WHAT TO DO IF YOU SMELL GAS”
• Do not try to light any appliance.
• Do not touch any electrical switch; do not use any
phone in your building.
• Immediately call your gas supplier from a neighbor’s
phone. Follow the gas supplier’s instructions.
• If you cannot reach your gas supplier, call the fire
department.
Do not use this Natural Gas control on a LP Gas
water heater. Improper operation could occur, re-
sulting in personal injury and/or death due to Car-
bon Monoxide poisoning, fire, or explosion. Check
for proper gas type as listed on the rating plate
affixed to the water heater.
FAILURE TO READ AND FOLLOW ALL INSTRUCTIONS BEFORE INSTALLING OR OPERATING THIS
CONTROL COULD CAUSE PROPERTY DAMAGE, PERSONAL INJURY AND/OR DEATH.
RETAIN INSTRUCTIONS FOR FUTURE REFERENCE.
WARNING
!
1. This control must be installed or serviced only by a
professional.
2. Do not use force when moving the gas control knob. If
you cannot turn the knob with hand pressure only, the
control must be replaced.
3. Do not use the control if the knob will not “pop up” after
being depressed while the knob is in the PILOT posi-
tion. The mechanism is damaged and the control must
be replaced. Shut off gas to the water heater.
4. For your safety, this control is supplied with tamper
resistant screws. Do not attempt to repair or adjust the
control. If you experience problems, replace the control
immediately. Continuing to use a damaged control
could result in fire and/or explosion.
5. An odorant has been added to the gas to help you
detect it. Before lighting, search for the odor of gas by
sniffing at floor level around the water heater.
6. In some situations, the gas may lose its odor. To detect
unodorized gas, you must have a gas detector which
can be purchased from your gas company. If you do not
have a detector and have the slightest suspicion that
gas may be present, get out of the house and call the
gas company. DO NOT RELY TOTALLY ON YOUR
NOSE.
Scald burns occur in under one second with 160°
water, which this thermostat will deliver if the
temperature dial is set at “VERY HOT”. Lower
settings of the temperature dial will reduce the risk
of scald and will reduce your fuel bill.
