Leak Check

After gas piping is completed, carefully check all piping

connections (factory- and field-installed) for gas leaks.

Use a leak detecting solution or other preferred means.

CAUTION

Figu re 28 shows thermostat designations for identifica- tion purposes. Refer to figure 29 for control box arra nge- ment, figure 30 for a detail of the Surelight _integrated

control, figure 32 for point-to-point field wiring and figure

33 for schematic wiring diagram and troubleshooting,

ELECTROSTATIC DISCHARGE (ESD)

Precautions and Procedures

A, IMPORTANT 1

1 - Install field make-up box on either side, inside orout of the cabinet. Knockouts are provided in box and cabinet to run wiring. See figures 26 and 27.

2 - Remove cap from knockout in blower deck on the same side as the installed make-up box.

iii::i:: i.................j

A field make-upbox is provided for line voltage wiring. Line voltage wiring to unit is done through the J69 jack

from the field make-up box to plug P69 from the control

box. See figures 26 and 27 for make-up box installation.
