tions.
7. Perform installation check out procedure (piping leak check,
line pressure measurement, manifold pressure adjustment,
etc.) as outlined in the unit installation instructions.
8. Turn OFF gas supply.
9. Turn OFF power to furnace. Connect jumper harness be-
tween LPLP switch and gas valve and gas valve wiring as
indicated in Figure 7 (single-stage models - some models
may require the use of long single-stage harness) or Fig-
ures 8-11 (two-stage models). Some two-stage models may
require the use of long jumper wires to accommodate con-
nection of the switch. (2nd long jumper wire can be taken
from long single stage harness.)
