If pressure exceeds 0.5 psig (14-in. wc), gas supply pipe must be disconnected from furnace and capped before pressure test. If test pressure is
equal to or less than 0.5 psig (14-in. wc), turn off electric shutoff switch located on furnace gas valve and accessible manual shutoff valve before
test.
The gas supply pressure shall be within the maximum and minimum inlet supply pressures marked on the rating plate with the furnace burners
ON and OFF.

PROCEDURE 5—ELECTRICAL CONNECTIONS

See Fig. 31 for field wiring diagram showing typical field 115-v and 24-v wiring. Check all factory and field electrical connections for tightness.
Field-supplied wiring shall conform with the limitations of 63°F (35°C) rise.

WARNING: ELECTRICAL SHOCK HAZARD

Failure to follow this warning could result in serious injury or death.
Blower access panel door switch opens 115-v power to control center. No component operation can occur. Do not bypass or close
switch with panel removed.

CAUTION: FURNACE MAY NOT OPERATE

Failure to follow this caution may result in furnace operation stopping and water pipes freezing during cold weather.
Furnace control must be grounded for proper operation or control will lock out. Control is grounded through green/yellow wire routed
to gas valve and burner box screw.
