Place Unit in Final Location
WARNING
Goodman 88
To prevent property damage, the unit should remain in an
upright position during all rigging and moving operations.
To facilitate lifting and moving when a crane is used,
place the unit in an adequate cable sling.
IMPORTANT: Place the unit in the final location and position it in
the proper orientation to the house so that connecting ducts,
electrical and gas supplies is easily done. Hoisting may be
required.
INSTALLATION INSTRUCTIONS
Gas Supply Requirements
This unit is equipped for use with Natural gas. A conversion kit is
required for use with propane. To order the correct conversion kit,
see your local distributor.
Gas supply piping should be installed in accordance with
local, state and national codes and the regulations of the
utility. Piping must be of adequate size to prevent undue
pressure drop. Consult the local utility or gas supplier for
complete details on special requirements for sizing gas
piping.
If local codes allow the use of a flexible gas appliance
connector, use a CSA design-certified outdoor flexible
stainless steel appliance connector or rigid gas supply line as
needed.
Hoisting
IMPORTANT: If using the bottom discharge with the roof curb,
the ductwork should be attached to the curb prior to installing the
unit. Ductwork dimensions are shown in the roof curb installation
instructions.
See "Roof Curb Installations Only" in "Location Requirements"
for the proper curb installation. Curbing must be installed in
compliance with the National Roofing Contractors Association
Manual.
Lower the unit onto the roof mounting curb. While rigging the
unit, the center of gravity will cause the condenser end to be
lower than the supply air end.
Rigging
Airflow Conversion
Units can easily be converted from horizontal to downflow airflow
delivery. In downflow or high-static installations, the installer
should measure the total external static and review the blower
performance charts before performing the installation. In some
installations, it will be necessary to change the blower speed to
provide proper airflow.
Horizontal Application
This unit is shipped ready for horizontal application.
