4.5 INSTALLATION OF STACK PROBE FOR PDS
FUNCTION
Install the probe for the Proven Draft Switch (PDS-1) in the
vent connector. The probe must be located between the
appliance and the power venter. The probe must be located
at least 3 vent diameters downstream of the draft hood, draft
diverter, or barometric damper. The probe placement should
also observe distances from elbows and tees as shown in
figure below. The tip of the probe MUST be flush with the
inner chimney wall to get a proper pressure reading.
4.6 CHECKING AND CHANGING ROTATION OF IPVB
350, 400 AND 500
To check the rotation of the impeller, it is necessary to be
able to see the impeller or the rotation of the cooling vanes at
the end of the motor housing.
Looking through the outlet of the fan, the rotation of the
impeller should be clockwise as shown in Fig. 13. Correct
rotation direction is also indicated by an arrow on the motor
end cover. There are holes in the end cover that allow you
to see the cooling vanes, but it is difficult to see the rotation
unless the fan is running very slowly.
It is possible for the fan to operate with improper rotation.
However, the fan will only provide 25-30% of full capacity.
Improper rotation damages the motor, and causes various
electrical faults at the Variable Frequency Drive.
Fan rotation can be changed by swapping the two phase
wires as shown on the wiring diagram in Fig.14.
