Reading an owner manual for this furnace it appears you can install it in a garage, but it comes with the following warning:
WHEN THIS FURNACE IS INSTALLED IN A RESIDENTIAL GARAGE, IT MUST BE INSTALLED
SO THE BURNERS AND IGNITION SOURCE ARE LOCATED NO LESS THAN 18 INCHES ABOVE THE
FLOOR. THIS IS TO REDUCE THE RISK OF IGNITING FLAMMABLE VAPORS WHICH MAY
BE PRESENT IN A GARAGE. ALSO, THE FURNACE MUST BE LOCATED OR PROTECTED TO
AVOID PHYSICAL DAMAGE BY VEHICLES. FAILURE TO FOLLOW THESE WARNINGS CAN CAUSE A
FIRE OR EXPLOSION, RESULTING IN PROPERTY DAMAGE, PERSONAL INJURY OR DEATH.
There is also a concern with some of the duct work for a garage installation. I found the following here:
"A few problems can occur from the locating the furnace in the garage.
"It comes down to proper installation.
"With no duct work for the return, can cause issues in the home, when only one low return is used.
"If the return is not sealed, you would be pulling unconditioned air or contaminated air in the system.
"The location and sizing of the supply ducts can be an issues when installed in the garage.
"Many times there is not a big enough opening and the supply trunk or flex is chocked down to enter into the attic. This can cause the static pressure to drastic increase and effect the systems performance.
"A furnace can be installed in the garage with no problems, but it must be installed properly!"

To keep legal happy, let me just say that I am not an HVAC contractor, and you should never even look at your furnace without having a qualified, liability accepting HVAC contractor present.
