Installation or service of this water heater requires ability equivalent to that of a licensed tradesman in the field involved. Plumbing, air supply, venting, gas supply, and electrical work are required.

Light the unit in accordance with the operation instructions label attached to the water heater.

Under no circumstances should the input rate exceed the input rate shown on the water heater rating plate. Over firing could result in damage or sooting of the water heater.

If the unit is exposed to the following, do not operate water heater until all corrective steps have been made by a factory authorized independent service contractor or qualified service professional.

1.Flooding to or above the level of the burner or controls

2.External firing

3.Damage

4.Firing without water

5.Sooting

Never operate the water heater without first being certain it is filled with water and a pressure relief valve is installed in the HOT WATER OUTLET PIPING of the WATER heater.

GENERAL INSTRUCTIONS

TO FILL THE WATER HEATER

1.Close the water heater drain valve by turning the knob or valve stem clockwise.

2.Open the cold water supply shut-off valve.

3.Open several hot water faucets to allow air to escape from the system.

4.When a steady stream of water flows from the faucets, the water heater is filled. Close the faucets and check for water leaks at the water heater drain valve, pressure relief valve, and the hot and cold water connections.

SEQUENCE OF OPERATION

1.Water heater senses the minimum operating water flow which starts the ignition sequence to light the burners.

2.Blower ON

3.Gas valve opens and spark igniter starts.

4.Main burner ON

5.Flame signal confirmed

6.Burner flame and combustion blower modulates to maintain selected outlet temperature

7.Water flow is also regulated to not exceed the capacity of the water heater for the temperature selected.

8.Water flow shuts off.

9.Burners shut off immediately, but combustion blower continues for another 65 seconds to purge heat from coil.
