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 of
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).
ATTENTION: Pressures in excess of 1/2 psig (14-in w.c.)
(3.5 kPa) on the fireplace gas valve will result in a hazardous
condition.

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.
GAS LINE CONNECTION
Remove the access panel from the right side of the fireplace
shown in Figure 18 to access the gas valve, gas flex line,
junction box, and system wiring.
Attach the gas flex line to the pre-installed gas line. Refer to the
Gas Supply section in this manual for details on the installation
requirements for the gas supply line.
