Checking Manifold Pressure
MILLIVOLT VALVES
Natural Gas will have a manifold pressure of approximately 3.5" w.c.
for maximum input or 1.7" w.c. for minimum input at the pressure
regulator outlet with the inlet pressure to the pressure regulator
from a minimum of 4.5" w.c. for the purpose of input adjustment to
a maximum of 10.5" w.c.
Propane Gas will have a manifold pressure approximately 10.0"w.c.
(2.49kPa) for maximum input or 4.9"w.c. for minimum input at the
pressure regulator outlet with the inlet pressure to the pressure
regulator from a minimum of 11.0"w.c. for the purpose of input
adjustment to a maximum of 13.0"w.c.
INTERMITTENT PILOT VALVES
Natural Gas will have a manifold pressure of approximately 3.5"
w.c. at the pressure regulator outlet with the inlet pressure to the
pressure regulator from a minimum of 7.0" w.c. for the purpose of
input adjustment to a maximum of 10.5" w.c.

Control Valve - Gas Pressure Check
The valve regulator controls the burner pressure which should be
checked at the pressure test point. Turn captured screw counter
clockwise 2 or 3 turns and then place tubing to pressure gauge over
test point (Use test point "A" closest to control knob). After taking
pressure reading, be sure and turn captured screw clockwise
firmly to re-seal. Do not over torque. Check for gas leaks.
