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 boss or the gas piping drip leg. See Honeywell VR9205 gas valve figure or White-Rodgers 36G54 gas valve figure for location of inlet pressure boss.

NOTE: If measuring gas pressure at the drip leg or Honeywell VR9205 gas valve, a field-supplied hose barb fitting must be installed prior to making the hose connection. If using the inlet pressure boss on the White-Rodgers 36G54 gas valve, then use the 36G 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.

Inlet Gas Supply Pressure

Natural Gas

Minimum: 5.0" w.c.

Maximum:10.0" w.c.

Propane Gas

Minimum: 11.0" w.c.

Maximum:13.0" w.c.

If supply pressure differs from table, make the necessary ad- justments to pressure regulator, gas piping size, etc., and/or consult with local gas utility.

5.Turn OFF gas to furnace at the manual shutoff valve and disconnect manometer. Reinstall plug before turning on gas to furnace.

6.Turn OFF any unnecessary gas appliances stated in step 3.
