Figure 5.6-25 Detail, Vent Fan Motor Orientation
5.6.6.2 Installation
Note: When REPLACING the Vent Fan Motor, a NEW Vent Fan Impeller
MUST also be installed (ref. 5.6.4).
Impeller and Motor MUST be considered
a “matched set”.
Note: Inspect Driver Magnet for signs of scoring or rubbing. If rubbing is
present, inspect burner casting magnetic cup for damage.
Replace if
necessary.
Note: If the Driver Magnet is scored sufficiently as to require replacement,
the Burner Housing MUST also be replaced (ref. 5.7.7).
1.
Apply Loctite 243 (blue) to four (4) flat-head countersunk screws. Insert the Motor into
the Vent Fan Housing, and using a #1 cross-tip screwdriver, secure the Motor into the
Housing with the screws.
Note: It may be necessary to rotate the motor until all 4 screw holes are
aligned because the screw hole pattern is ‘keyed’.
2.
Install Vent Fan Impeller (ref. 5.2.4).
3.
Install Vent Fan Shroud (ref. 5.2.3).
