SERVICE AIDS

1.This type product is polarity sensitive. Be certain that your electrical supply wire neutral has no voltage.

2.This unit will produce condensation — quite heavily at times. The outlet drain hose must be allowed to drain. Exhaust Vent piping must also drain condensate. Code 11 error would imply that these must be checked.

3.If the unit is located in a cold climate, take steps to ensure that exhaust vapors are not pulled into the air intake. Terminate both pipes on direct vent installations in the same area, but max- imize the distance between them.

4.Do not combine vent these units.

5.Pushing the reset button at random times may alter setting of the control. Note the sequence of operation comments on when to push this button.

6.If you make a setting change, cycle the heater with this new setting to lock it into memory.

7.The first items to check on a service call

a.Correct venting installation

b.Drainage of condensate from hose and exhaust vent pipe

8.SUF models are certified to 6.800 ft. above sea level with the standard orifice — air and gas.

9.The temperature display board indicates average tank water temperature. If one tank sensor is “open”, the indicator will display the active sensor temperature. (Because the top tank sensor also contains the high limit-24V-sensor, disconnecting this from the control board results in an error code (04).)

10.Temperature and pressure relief valve operation. Weeping usually indicates thermal expan- sion. Large volume discharge usually indicates excessively hot water operation.

11.SUF models are well within decimal level limits, but if you desire to lower the installation level approximately 6 decibels a muffler (Part No. 195334) may be installed in the exhaust vent.
