Valve Access; Check Gas Pressure - Monessen Hearth ARTISAN Series Installation Manual

E. Valve Access
The valve and controls are located in the appliance con-
trol area. See Figure 5.4.
The controls area can be accessed by lifting engine as-
sembly as shown in Figure 5.4.

supports, provided under the engine, against lower
front space at the bottom of the face, and slide into
the slots at the bottom of the engine assembly. See
Figure 5.4.
• Locate valve on face of engine assembly.
• Gas line sizing requirements will be determined in
ANSI Z223.1 National Fuel Gas Code in the USA.
• Pressure requirements are:
These pressures can be verified by lifting engine and
removing control cover to reveal the valve.
When an appliance is connected to a fixed piping sys-

F. Check Gas Pressure
Check the gas pressure with the appliance burning and
the control set to HIGH.
The valve regulator controls the burner pressure which
should be checked at the pressure test point.
Turn captured screw counterclockwise two or three turns
and then place tubing to pressure gauge over test point.
Use test point "A" closest to gas inlet. After taking pres-
sure reading, be sure and turn captured screw clockwise
firmly to reseal. Do not over torque. Check for gas leaks.
See Figure 5.5.
