5. Locating the Unit - [See Table 1]
•
Locate furnace so flue connection to chimney is short,
direct and consists of as few elbows as possible.
• Centralize furnace location with respect to supply and
return air ductwork. Central location minimizes trunk
duct sizing.
•
All models may be installed on combustible floors.
6. Furnace Used In Conjunction With Air
Conditioning
• Install furnace in parallel with or upstream from
evaporator coil to avoid condensation in heat
exchanger.
• When installed in parallel, prevent chilled air from
entering furnace by use of dampers or air controlling.
• Manually operated dampers must have a control to
prevent operation of either system unless dampers
are in full heat or full cool position.
• Air heated by the furnace shall not pass through
evaporator coil unless coil is specifically approved for
such service.
• Check and adjust blower speed to compensate for
pressure drop caused by evaporator coil.
• Maintain required clearance between bottom of coil
drain pan and top of heat exchanger as specified by
coil manufacturer.
