Save A Service Call - Rheem Integrity 20 Owner's Manual And Installation Instructions

Check the items below before making a service call. You will be charged for attending
to any condition or fault, which is not related to manufacture or failure of a part (refer
to Warranty on page 28).
NO DISPLAY ON THE CONTROLLER
Is the controller turned on? Press the on/off button (refer to Temperature Control
on pages 7 to 13).
Is the water heater plugged in and the power outlet switched on?
Is power available in the house? Try using another electrical appliance.
COLD WATER FROM HOT TAP
Is the controller turned on? Press the on/
off button (refer to Temperature Control on
pages 7 to 13).
Close the hot tap, wait 10 seconds and
open the hot tap again.
Is the hot tap open enough? The burners
will not light if the flow rate is less than 3 L/
min.
Is the water heater plugged in and the
power outlet switched on?
Is power available in the house? Try using
another electrical appliance.
Is the isolation valve in the gas line open?
Is there a gas supply to the rest of the
house? Try lighting another gas appliance.
Has the gas line been purged of air after
installation? Refer to your plumber.
WATER IS TOO HOT OR NOT HOT ENOUGH
Does the controller you are using have priority? (refer to Temperature Control
on pages 7 to 13)
NO WATER FROM HOT TAP
This may indicate a restriction in or failure of the cold water supply to the water
heater. Check for water flow at other taps and that the cold water isolation valve
(refer to page 18) is fully open.
WATER FLOW FLUCTUATES
Are there other hot taps open, or appliances such as a dishwasher or washing
machine, in use at the time? The shower should be adjusted so the hot tap is fully
open. To check the flow of the water, ensure only one hot tap (or appliance) is on at
one time. More than two hot taps in use at the same time may cause a decrease in
the hot water flow from the taps.
FAN CONTINUES TO RUN AFTER WATER HEATER OPERATION HAS STOPPED
This is normal operation. The fan may run for up to six minutes after the burners
extinguish, to prepare for the next ignition.
