SAFETY CONSIDERATIONS

CAUTION: Application of this furnace should be in-

doors with special attention given to vent sizing and

material, gas input rate, air temperature rise, unit leveling,

and unit sizing. Improper installation or misapplication of

furnace can require excessive servicing or cause prema-

ture component failure.
