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 inch w.c. (.871 kPa) at the valve
outletwiththeinletpressuretothevalvefromaminimumof4.5inch
w.c. (1.120 kPa) for the purpose of input adjustment to a maximum
of 14.0 inch w.c. (3.484 kPa). Propane gas models will have a
manifold pressure approximately 10.0 inch w.c. (2.49 kPa) at the
valve outlet with the inlet pressure to the valve from a minimum of
10.8 inch w.c. (2.68 kPa) for the purpose of input adjustment to a
maximum of 14.0 inch w.c. (3.484 kPa).

Note: Island and Room Divider installation is possible as long as the horizontal portion of the vent system does not exceed 20 feet with
a minimum vertical run of 8 feet. See details in Venting Section.
Note: When installing this appliance against an exterior wall, insulate to applicable insulation codes.
When you install your Direct Vent Fireplace in Room divider or Flat on wall corner positions, a minimum of 6 inches clearance must be
maintained from the perpendicular wall and the front edge of the appliance.
