REMOVE LOW GAS PRESSURE SWITCH
NOTE: There are 2 ways that the Low Gas Pressure Switch
(LGPS) could have been installed during the original natural to
Propane gas conversion.
All 14 3/16-in Casings or Vent Passed Between Inducer
Assembly and Burner Assembly
If the vent pipe passes between the inducer and burner assembly,
or the furnace is a 14 3/16-in. wide casing, the switch may have
been installed as follows (See Fig 9).
1. Remove low gas pressure switch, brass street 90 ° elbow,
brass Hex nipple, brass tee and black iron street 90 ° elbow
from the gas valve inlet pressure tap. (See Fig 9.)
