MAINTENANCE AND SERVICE
Checking Manifold Pressures
Both propane and natural gas valves have a built-in pressure
regulator in the gas valve. Natural gas models will have a
manifold pressure of approximately 3.5-in w.c. (.871 kPa)
at the valve outlet with the inlet pressure to the valve from
a minimum of 4.5-in w.c. (1.120 kPa) for the purpose of
input adjustment to a maximum of 14.0-in w.c. (3.484
kPa). Propane gas models will have a manifold pressure
approximately 10.0-in w.c. (2.49 kPa) at the valve outlet with
the inlet pressure to the valve from a minimum of 10.8-in w.c.
(2.68 kPa) for the purpose of input adjustment to a maximum
of 14.0-in w.c. (3.484 kPa).
If one of the procedures results in pressures in excess of 1/2 psig
(14-in w.c./3.5 kPa) on the fireplace gas valve, it will result in a
hazardous condition.
