Part 9 - Start-Up Procedure
FOR YOUR OWN SAFETY READ BEFORE OPERATING
1. This water heater does not have a pilot. It is equipped with
an ignition device which automatically lights the burner. Do
not try to light the burner by hand.
2. BEFORE OPERATING: Smell all around the water heater
area for gas. Be sure to smell next to the oor because some
gas is heavier than air and will settle on the oor.
WHAT TO DO IF YOU SMELL GAS
• Do not try to light any water heater.
• Do not touch any electric switch, do not use any phone
in your building.
• Immediately call your gas supplier from a neighbor’s
phone. Follow the gas suppliers’ instructions.
• If you cannot reach your gas supplier, call the re
department.
• Turn o the gas shuto valve (located outside the water
heater) so that the handle is crosswise to the gas pipe.
If the handle will not turn by hand, don’t try to force
or repair it, call a qualied service technician. Force or
attempted repair may result in a re or explosion.
4. Do not use this water heater if any part has been under
water. Immediately call a qualied service technician to
inspect the water heater and to replace any part of the control
system and any gas control that has been damaged.
5. The water heater shall be installed so the gas ignition
system components are protected from water (dripping,
spraying, rain, etc.) during water heater operation and
service (circulator replacement, condensate trap, control
replacement, etc.)
Failure to follow these instructions could result in property
damage, serious personal injury, or death.
A. Operating Instructions
If you smell gas, STOP. Follow listed safety instructions above.
If you do not smell gas, follow the next steps.

To assure adequate purging, open all hot water faucets.
Ensure the water heater is full of water before ring the
burner. Failure to do so will damage the heater. Such damage
IS NOT covered by warranty, and could result in property
damage, serious personal injury, or death.
