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.

NOTE - If emergency shutoff is necessa04 shut off the main manual gas valve and disconnect the main power to the furnace. The installer should properly label these devices.

&CAUTION

The furnace must be isolated from the gas supply system by closing its individual manual shut-off valve during any pressure testing of the gas supply system at pressures less than or equal to 1/2 psig (3.48 kPa, 14 inches w.c.).

ELECTROSTATIC DISCHARGE (ESD)

Precautions and Procedures

&CAUTION

The unit is equipped with a field make-up box, The make- up box may be moved to the right side of the furnace to fa- cilitate installation, If the make-up box is moved to the right side, the excess wire must be pulled into the blower compartment. Secure the excess wire to the existing harn- ess to protect it from damage.
