DAMAGE. REPORT ANY DAMAGE TO THE FREIGHT CARRIER. After inspection, keep the
unit in its shipping container until it is installed. It can be installed on combustible and
non-combustible floors. Minimum clearances are:

needed on the right side.
Level the unit front to rear and left to right by adjusting its legs. Levelness may be
checked by using a spirit level on top of the cabinet.
A free flow of air around the boiler promotes efficient operation. Similarly, keep the
area directly around the appliance clear of combustible material.
Installation must conform with local codes, or in the absence of local codes, with the
National Electrical Code should be followed (ANSI/NFPA-70-1987 - or latest edition).
