lator, a pilot/sensor/electrode and an ON/OFF switch.
The controls are located behind the access door. Ro-
tate the door down to open. See Figure 1.
Minimum inlet gas supply pressure for purpose of input
adjustment is 4.5 inches w.c. (1.13kPa) for natural gas
and 11 inches w.c. (2.75kPa) for propane. Manifold (out-
let) pressures should be set at 3.5 inches w.c. (.8kPa)
for natural gas models and 9.5 inches w.c. (2.36kPa) for
propane models.
