Venting System Inspection

The venting system of an indoor water heater should be inspected annually to ensure all of the vent sections are secure and air-tight.

It is recommended that qualified service personnel familiar with Category III venting inspect the venting system.

Check vent connection joint sections with a solution of soapy water to assure air-tightness while the unit is operating.

Bubbles around a joint connection indicates a seal leak. Refer to page 10 for vent sealing instructions.

DO NOT operate the unit if vent system shows signs of leaking exhaust.

Check to make sure that the air intake and vent outlet on the OUTDOOR water heater or the air intake filter and the vent terminal on the INDOOR water heater has not been blocked or contain debris.

Burner Inspection

Visually inspect the main burners annually.

Through the side sight glass, inspect the burner flame. Blue flames should be seen when the main burner is firing. See figure on left for location of sight glass.

If any unusual burner operation is noted, the water heater should be shut off until qualified service assistance can be obtained.

!CAUTION: For your safety, burner inspection and cleaning should be performed only by qualified service personnel.

For cleaning, a vacuum cleaner can be used on the burner.

Vacation and Extended Shut-Down

NOTICE: Refer to the Freeze Protection Section on page 31.

If the water heater is to remain idle for an extended period of time, the power and water to the appliance should be turned off.

The water heater and piping should be drained if they might be subjected to freezing temperatures.

After a long shut-down period, the water heater’s operation and controls should be checked by qualified service personnel.

!CAUTION: Do not operate without the condensate trap connected to the vent and routed to the proper drain.

Condensate Trap Inspection

On a regular basis, inspect the condensate trap to ensure there is enough water in the trap and the condensate is draining properly.

Ensure that condensate is disposed of per local codes and regulations.
