INITIAL OPERATION
FOR YOUR SAFETY, READ
BEFORE OPERATING
Check the GAS and WATER CONNECTIONS for leaks
before firing unit for the first time.
Open the main gas supply valve to the unit using only
your hand to avoid any spark. Never use tools. If the
knob will not turn by hand, do not try to force it; call a
qualified service technician. Forced repair may result in
a fire or explosion due to gas leaks.
Be sure to check for the presence of leaking gas
toward the bottom of the unit because some gases are
heavier than air and may settle towards the floor.
Check the GAS PRESSURE. Refer to pg. 17.
Do not try to light the burner manually. It is equipped
with an electronic ignition device which automatically
lights the burner.
Check for PROPER VENTING and COMBUSTIBLE
AIR to the water heater.
Purge the GAS and WATER LINES to remove any air
pockets.
Do not use this water heater if any part has been
submersed under water. Immediately call a qualified
service technician to inspect the water heater and to
replace any damaged parts. •
