PART 9 – START-UP PROCEDURE
1. This water heater does not have 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 floor because some gas is
heavier than air and will settle on the floor.

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 fire department.

Turn off gas shutoff valve (located outside of 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 qualified service technician. Force or attempted repair may result in a fire
or explosion.
4. Do not use this water heater if any part has been under water. Immediately call a qualified 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.
