Mounting older counterflow gas furnace sideways

Does anyone know if it's okay to mount an older counterflow natural gas furnace on its side? I know the newer units are okay sideways, but not sure about the older ones. I just pulled a working unit out of a repo house I'm renovating and considering reusing this furnace in my workshop.

The furnace is approximately from 1988, 80+ power vented natural gas, 3" vent, I believe 80k btu. Squirrel cage works good, induction blower works good, burner seems to work good. I would basically hang it from the ceiling with none or minimal ducting other than a filter rack on the intake.

Some counterflows can be turned sideways, some can't. A make, model, & serial number might help.

The plate on the front panel reads "Kenmore Power Miser 80".

The label inside the service compartment:

Manufactured by HQCO Lavergne, TN
Model No.: NDGE050AD01 867.768310
Ser No.: L904533254
Input BTU: 50,000

There is also a wiring diagram and a number of basic safety and operation stickers, but nothing regarding installation or mounting orientation.

Most HQ counterflow units are made to be installed as counterflow only. The newer ones with an 'M' in the model number are multi-position. Your's was made in 1990, 45th week.

Thanks for the info Grady. I think I might pass on this one and keep my eye out for a better unit.
