Checking Manifold Pressure

VFP(32,36)FP(30,31)LN (Natural gas) will have a manifold pressure of approximately 3.5" w.c. (.871kPa) for maximum input or 1.7" w.c. (.423kPa) for minimum input at the pressure regulator outlet with the inlet pressure to the pressure regulator from a minimum of 4.5" w.c. (1.120kPa) for the purpose of input adjustment to a maximum of 10.5" w.c. (2.614kPa). VFP(32,36)FP(20,21)LN (Natural gas) will have a manifold pressure of approximately 6.0" w.c. (1.49kPa) at the pressure regulator outlet with the inlet pressure to the pressure regulator from a minimum of 7.0" w.c. (1.74kPa) for the purpose of input adjustment to a maximum of 10.5" w.c. (2.615kPa). VFP(32,36)FP(30,31)LP (Propane gas) will have a manifold pressure approximately 10.0"w.c. (2.49kPa) for maximum input or 4.9"w.c. (1.220kPa) for minimum input at the pressure regulator outlet with the inlet pressure to the pressure regulator from a minimum of 11.0"w.c. (2.739kPa) for the purpose of input adjustment to a maximum of 13.0"w.c. (3.237kPa).

VFP(32,36)FP(20,21)LP (Propane gas) will have a manifold pressure approximately 10.0"w.c. (2.49kPa) at the pressure regulator outlet with the inlet pressure to the pressure regulator from a minimum of 11.0"w.c. (2.739kPa) for the purpose of input adjustment to a maximum of 13.0"w.c. (3.237kPa).

A test gage connection is located downstream of the gas appliance pressure regulator for measuring gas pressure. The connection is a 1/8 inch (3mm) N.P.T. plugged tapping.

VFP(32,36)FP(30,31) Millivolt Control

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.

Minimum Wall and Ceiling Clearances (Figure 4)

Sidewall Clearances: The clearance from the inside of the ﬁreplace to any combustible wall should not be less than 2".

Fireplace Side and Back Clearances: The ﬁreplace outer casing sides and back have zero clearance to combustibles.

Ceiling Clearances: The ceiling height should not be less than 36" from the top of the hood.

Mantel Clearances: Vent free ﬁreplace models must use the hood supplied with the ﬁreplace. If a combustible mantel is installed, it must meet the clearance requirements detailed above.
