 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 p. 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.
