5 − Return air from bottom and one side.
Refer to Engineering Handbook for additional information.
G61MPVT applications which include side return air
and a condensate trap installed on the same side of the
cabinet require either a return air base or field−fabri-
cated transition to accommodate an optional IAQ ac-
cessory taller than 368mm (14.5 inches).

Removing the Bottom Panel
Remove the two screws that secure the bottom cap to the
furnace. Pivot the bottom cap down to release the bottom
panel. Once the bottom panel has been removed, reinstall
the bottom cap. See figure 5.

Horizontal Applications
G61MPVT furnaces, with the exception of the
G61MPVT−60D−135, can be installed in horizontal applica-
tions with either right− or left−hand air discharge. The
G61MPVT−60D−135 can only be installed in horizontal ap-
plications with right−hand air discharge.
Refer to figure 6 for clearances in horizontal applications.

‡
*Front clearance in alcove installation must be 610 mm (24 inch-
es). Maintain a minimum of 610mm (24 inches) for front service ac-
cess.
**A 140mm (5−1/2) service clearance must be maintained below
the unit to provide for servicing of the condensate trap.
‡
For installations on a combustible floor, do not install the furnace
directly on carpeting, tile or other combustible materials other
than wood flooring.
FIGURE 6
This furnace may be installed in either a roof space or un-
der floor. Install the furnace on a field−fabricated raised
platform, as shown in figure 7. The unit must be supported
at both ends and beneath the blower deck to prevent sag-
ging.
NOTE −
In horizontal applications, the unit must be lev-
el side−to−side. The unit may be tilted back−to−front a
maximum of 25mm (1 inch) to ensure proper draining
of the heat exchanger.
The heat exchanger coil will not
drain properly if the unit is tilted backward.
