This furnace can NOT be common vented or connected
to any type B, BW or L vent or vent connector, nor to
any portion of a factory-built or masonry chimney. If
this furnace is replacing a previously common-vented
furnace, it may be necessary to resize the existing vent
and chimney to prevent oversizing problems for the
other remaining appliance(s). See Venting and
Combustion Air Check in Gas Vent lnstallation section.
This furnace MUST be vented to the outside.
Failure to properly vent this furnace or other
appliances can result in death, personal injury and/or
property damage.
Locationand Clearances
1. Refer to Figure 1 or Figure 2 for typical installation and
basic connecting parts required. Refer to Figure 4 for typi-
cal horizontal direct vent installation and basic connecting
parts required. Supply and return air plenums and duct are
also required.
2. If furnace is a replacement, it is usually best to install the
furnace where the old one was. Choose the location or
evaluate the existing location based upon the minimum
clearance and furnace dimensions (Figure 3).
CAUTION
Special precautions MUST be made if installing furnace in an
area which may drop below freezing. This can cause
improper operation or damage to equipment. If furnace
environment has the potential of freezing, the drain trap and
drainline must be protected. The use of electric heat tape or
RV antifreeze is recommended for these installations. (See
"Condensate Trap Freeze Protection Section")
Do NOT operate furnace in a corrosive atmosphere
containing chlorine, fluorine or any other damaging
chemicals. Refer to Combustion & Ventilation Air section,
