VENTING OF GAS VALVES AND PRESSURE SWITCHES
The optional gas pressure switches may be provided with threaded termination points to be vented to the atmosphere, outside the building.
The gas pressure regulation function is provided by the ratio gas valve which does not require installation of a vent line. The optional gas
pressure switches are installed in the upper chamber of the appliance. Threaded vent line connections from components requiring an
external vent line are provided on the component. These vent line connection points may be accessed by removing the top of the
appliance. Local codes may require the routing of these bleeds and vents to the atmosphere, outside the building. Proper routing of vent
lines to the atmosphere from the factory supplied termination points is the responsibility of the installing contractor.
