High Efficiency and
Flexibility Designed to Meet
the Needs of New Homes
The model 58MCB combines high
efficiency with flexibility to meet the
changing needs of new home
construction. The unique 4-way,
multipoise design of the 58MCB allows
for installation in upflow, downflow,
horizontal left, and horizontal right
orientations, meaning it is perfect for a
variety of installation applications. With
the exception of the 140 size unit, all
sizes of the 58MCB can be installed in a
manufactured (mobile) home when the
optional kit is used and in installations
with elevations up to 10,000 ft (140
size unit limitation 7,000 ft). The
furnace is factory configured for upflow
application but can easily be made ready
for downflow or horizontal installation.
With the exception of the 140 size, all
sizes can be installed with 2-pipe or
1-pipe venting. The 140 size can be
installed only as a 2-pipe system.
Horizontal applications offer the ad-
vantage of reduced space requirements
by locating the furnace in an attic or
crawlspace, freeing space formerly ded-
icated to a furnace or utility room.
The 58MCB is specifically designed
to meet the needs of home builders and
new home owners. Home builders
benefit from the 58MCB’s unmatched
flexibility and by building a reputation
of using quality appliances in homes.
Home owners benefit by energy savings

The components of the 58MCB
represent the finest in the industry. Hot

center provide reliable and efficient
ignition. The combustion inducer is
