General Safety Information

Fire or Explosion Hazard

Do not store or use gasoline or other flammable vapors and liquids in the vicinity of this or any other appliance.

Avoid all ignition sources if you smell gas.

Do not expose water heater controls to excessive gas pressure.

Use only the gas shown on the water heater rating label.

Maintain required clearances to combustibles.

Keep ignition sources away from faucets after extended periods of non-use.

Read instruction manual before

installing, using or servicing

water heater.

Breathing Hazard - Carbon Monoxide Gas

Do not obstruct water heater air intake with insulating blanket.

Gas and carbon monoxide detectors are available.

Install water heater in accordance with the instruction manual.

Breathing carbon monoxide can cause brain damage or death. Always read and understand instruction manual.

CAUTION

Property Damage Hazard

All water heaters eventually leak.

Do not install without adequate drainage.

Electrical Shock Hazard

Turn off power to the water heater before performing any service.

Label all wires prior to disconnecting when performing service. Wiring errors can cause improper and dangerous operation.

Verify proper operation after servicing.

Failure to follow these instructions can result in personal injury or death.

Fire Hazard

For continued protection against risk of fire:

Do not install water heater on carpeted floor.

Do not operate water heater if flood damaged.

Fire and Explosion Hazard

Use joint compound or Teflon tape compatible with propane gas.

Leak test before placing the water heater in operation.

Disconnect gas piping and main gas shutoff valve before leak testing.

Install sediment trap in accordance with NFPA 54.

Fire and Explosion Hazard

Do not use water heater with any gas other than the gas shown on the rating label.

Excessive gas pressure to gas valve can cause serious injury or death.

Turn off gas lines during installation.

Contact a qualified installer or service agency for installation and service.

Jumping out control circuits or components can result in property damage, personal injury or death.

Service should only be performed by a qualified service agent using proper test equipment.

Altering the water heater controls and/or wiring in any way could result in permanent damage to the controls or water heater and is not covered under the limited warranty.

Altering the water heater controls and/or wiring in any way could result in altering the ignition sequence allowing gas to flow to the main burner before the hot surface igniter is at ignition temperature causing delayed ignition which can cause a fire or explosion.

Any bypass or alteration of the water heater controls and/or wiring will result in voiding the appliance warranty.
