Condensing Heat Exchanger Kit
Installation Instructions
Part No. 312731-755 through -761
NOTE:
Read the entire instruction before starting the installation.
INTRODUCTION
This instruction covers installation of a polypropylene-laminated
(PPL) steel condensing heat exchanger and collector box assembly
kit in an upflow condensing furnace. See Table 1 for furnace and
kit combinations.
NOTE:
If this kit is used to replace a stainless steel condensing
heat exchanger in a Model 398A, Series B through F, or a 58SX,
Series 110 through 180 Furnace, some modifications to the vent
system or unit may be necessary. Refer to Step 6—Replacing a
stainless steel condensing heat exchanger with a PPL condensing
heat exchanger.
NOTE:
Obtain a releasing agent (Pam or equivalent) and RTV
sealant (G.E. 122, 162, or Dow-Corning 738) before starting the
installation.
SAFETY CONSIDERATIONS
Installation and service of heating equipment can be hazardous due
to gas and electrical components. Only trained personnel should
install or service heating equipment.
Untrained personnel can perform basic maintenance functions
such as cleaning and replacing filters. All other operations should
be performed by trained service personnel. When working on
heating equipment, observe precautions in literature, and on tags
and labels attached to the unit.
Follow all safety codes. Wear safety glasses and work gloves.
Have a fire extinguisher available.
Before beginning any installation or modification, be sure the
main electrical disconnect switch is in the OFF position.
Electrical shock can cause personal injury or death.
