SAVE A SERVICE CALL

Check the items below before making a service call. You will be charged for attending to any condition or fault that is not related to manufacture or failure of a part.

NOT ENOUGH HOT WATER (OR NO HOT WATER)

Are you using more hot water than you think? Is one outlet (especially the shower)

using more hot water than you think? Very often it is not realised the amount of hot water used, particularly when showering. Carefully review the family’s hot water usage. Have your plumber fit a flow control valve to each shower outlet to reduce water usage.

Pilot flame alight?

Check the pilot flame is burning by viewing through the opening in the top of the front cover. Relight the pilot flame according to the lighting instructions (refer to “Lighting the Water Heater” on page 24).

Temperature pressure relief valve running

Is the relief valve discharging too much water? (Refer to “Temperature Pressure Relief Valve Running” on page 11).

Thermostat setting

Ensure the thermostat setting is appropriate. You may choose to adjust the thermostat upwards to gain additional hot water capacity.

Note: Hotter water increases the risk of scald injury.

Water heater size

Do you have the correct size water heater for your requirements? The sizing guide in the Rheem sales literature and on the Rheem website (www.rheem.com.au) suggests average sizes that may be needed.

WATER NOT HOT ENOUGH

You may find that due to heavy hot water usage the water temperature may be lower than normally expected.
