6.3 FLAME DETECTOR
Flame detector (kit P/N 24356-2) is used on ALL RECON Water Heater Models. The flame
detector is located on the flange of the blower-side intake manifold as shown in Figure 6-1. The
flame detector may be hot. Allow the unit to cool sufficiently before removing the flame detector.
To inspect or replace the flame detector:
Flame Detector Inspection/Replacement
1. Set the ON/OFF switch on the control panel, to the OFF position. Disconnect AC power from
the unit.
2. Remove the side and rear panels from the unit.
3. Disconnect the flame detector lead wire.
4. Remove the two (2) Phillips head screws securing the flame detector to the intake manifold
(Figures 6-1).
5. Remove the flame detector and gasket from the manifold flange.
6. Thoroughly inspect the flame detector. If eroded, the detector should be replaced. Otherwise,
clean the detector with a fine emery cloth.
7. Reinstall the flame detector with a new flame detector gasket with the two screws removed in
step 4.
8. Reconnect the flame detector lead wire.
9. Reinstall the side and rear panels on the unit.
6.4 COMBUSTION CALIBRATION
Combustion settings must be checked at the intervals shown in Table 6-1 as part of the
maintenance requirements. Refer to Chapter 4 for combustion calibration instructions.
6.5 SAFETY DEVICE TESTING
Systematic and thorough tests of the operating and safety devices should be performed to ensure
that they are operating as designed. Also, certain code requirements specify that these tests be
performed on a scheduled basis. Test schedules must conform to local jurisdictions. The results
of the tests should be recorded in a log book. See Chapter 5 for Safety Device Test Procedures.
