The line pressure supplied to the gas valve must be within the range specified in the chart on the next page. The supply pressure can be measured at the gas valve inlet pressure tap or at a hose fitting installed in the gas piping drip leg. The supply pressure must be measured with the unit OFF. To measure inlet pressure, use the following procedure.

1.Turn OFF gas to furnace at the manual gas shutoff valve external to the furnace.

2.Turn OFF all electrical power to the system.

3.Inlet pressure tap connections:

a.Honeywell VR8215 Valve:

Remove the inlet pressure boss plug. Install an 1/8” NPT hose barb fitting into the outlet pressure tap.

b.White-Rodgers 36G22 valve:

Back inlet pressure test screw (inlet pressure boss) out one turn (counterclockwise, not more than one turn).

4.Attach a hose and manometer to the outlet pressure barb fitting (Honeywell valve) or inlet pressure boss (White- Rodgers valve).

5.Turn ON the gas supply.

6.Turn On power and close thermostat “R” and “W” contacts to provide a call for heat.

7.Using a leak detection solution or soap suds, check for leaks at outlet pressure boss plug (Honeywell valve) or screw (White-Rodgers valve). Bubbles forming indicate a leak. SHUT OFF GAS AND REPAIR ALL LEAKS IMMEDIATELY!

8.Measure the gas supply pressure with burners firing. Adjust supply pressure using the Inlet Gas Supply Pressure table shown below. If supply pressure reading differs from the table, make necessary adjustments to pressure regulator, gas piping size, etc., and/or consult with local gas utility.

 

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.

9.Turn OFF all electrical power and gas supply to the system.

10.Remove the manometer hose from the hose barb fitting or inlet pressure boss.

11.Replace inlet pressure tap: a. Honeywell VR8215 valve:

Remove the 1/8” NPT hose barb fitting from the inlet pressure tap. Replace the inlet pressure boss plug and seal with a high quality thread sealer.

b. White-Rodgers 36G22 valve:

Turn inlet pressure test screw in to seal pressure port (clockwise, 7 in-lb minimum).

12.Retest for leaks. If bubbles form, SHUT DOWN GAS AND REPAIR LEAKS IMMEDIATELY.

13.Turn ON electrical power and gas supply to the system.

14.Turn valve switch ON.

GAS MANIFOLD PRESSURE MEASUREMENT AND ADJUSTMENT

CAUTION

TO PREVENT UNRELIABLE OPERATION OR EQUIPMENT DAMAGE, THE INLET GAS SUPPLY PRESSURE MUST BE AS SPECIFIED ON THE UNIT RATING PLATE WITH ALL OTHER HOUSEHOLD GAS FIRED APPLIANCES OPERATING.

This valve is shipped from the factory with the regulator preset (see control label).

Consult the appliance rating plate to ensure burner manifold pres- sure is as specified. If another outlet pressure is required, follow these steps.

1.Turn OFF gas to furnace at the manual gas shutoff valve external to the furnace.

2.Turn OFF all electrical power to the system.

3.Outlet pressure tap connections:

a.Honeywell VR8215 valve:

Remove the outlet pressure boss plug. Install an 1/8” NPT hose barb fitting into the outlet pressure tap.

b.White-Rodgers 36G22 valve:

Back outlet pressure test screw (outlet pressure boss) out one turn (counterclockwise, not more than one turn).

4.Attach a hose and manometer to the outlet pressure barb fitting (Honeywell valve) or outlet pressure boss (White- Rodgers valve).

5.Turn ON the gas supply.
