Honeywell Model VR9205 Connected to Manometer
1. Turn OFF gas to furnace at the manual gas shutoff valve
external to the furnace.
2. Connect a calibrated water manometer (or appropriate gas
pressure gauge) at either the gas valve inlet pressure Tap
or the gas piping drip leg. See Honeywell gas valve figure
or White-Rodgers gas valve figure for location of inlet
pressure Tap.
NOTE: If measuring gas pressure at the drip leg or Honeywell gas
valve, a field-supplied hose barb fitting must be installed prior to
making the hose connection. If using the inlet pressure Tap on the
White-Rodgers gas valve, then use the 36G/J Valve Pressure Check
Kit, Goodman Part No. 0151K00000S.
3. Turn ON the gas supply and operate the furnace and all
other gas consuming appliances on the same gas supply
line.
4. Measure furnace gas supply pressure with burners firing.
Supply pressure must be within the range specified in the
Inlet Gas Supply Pressure table.
