MULTIPLE HANGING & DRAFT INDUCER POSITIONS
The heater can be mounted horizontally or at an angle of 45º maximum from horizontal. Make sure the long axis
of heater is level.
Multiple draft inducer positions can also be used as shown in the diagrams. This allows for the desired
configuration of flue venting. Regardless of the position chosen, the junction box must remain horizontal as
shown. This may be achieved as follows:
1. Remove the three (3) ¼-20 locknuts securing the motor and blower wheel assembly.
2. Pull the motor and blower wheel assembly with the motor plate slightly from the end of the housing studs.
Use care not to damage the motor leads.
3.
Rotate the junction box assembly to the upright position using the multi-hole mounting bracket.
4. Replace the motor and blower assembly. Tighten the locknuts.
5. Horizontal and 45º draft inducer positions can allow the plastic vacuum air tube to sag. The air tube should
be shortened to prevent a downward sag that could allow condensation build-up in the tube.
