SERIES
The heater can be mounted horizontally or up to an angle of 45º maximum from horizontal. When the heater is to be angle
mounted, make sure the draft inducer assembly is on the lower side of the heater. 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.
15.1) MULTIPLE HANGING & DRAFT INDUCER POSITIONS — LTU 80-250
& LTS 40-250 SERIES
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.
