resideo V5306 Servo Pressure Regulators Instruction Manual

V5306, V5307, V5308, and V5309 Servo Pressure Regulators
FOR THE V400, V800, VR400, VR800, AND VR8440 FAMILIES OF COMBINATION GAS CONTROLS

INSTALLATION INSTRUCTIONS

APPLICATION

These Servo gas pressure regulators are for Adatrol (add-on) or replacement use on Resideo V400, V800, VR400, VR800, and VR8440 combination gas controls. Utilizing the Servo principle of operation, they control burner manifold pressure by repositioning the main valve diaphragm.

FEATURES

• Provide straight line regulation.
• The V5306 provides standard pressure regulation.
• The V5307 provides “step opening” regulation. It restricts the flow of gas during the burner ignition period, minimizing burner concussion and flame roll-out.
• The V5308 is manually adjustable to a HI setting (rated input) or to a LO setting. During mild weather, the LO setting prolongs the period of burner operation resulting in closer temperature control and greater comfort.
• The V5309 is for use on mobile homes and recreational vehicles. Depending on the type of fuel available, it can be manually set for operation on natural or LP gas.
• All four types of regulators are interchangeable and adapt to all pipe sizes and capacities.
• Regulators mount on the top surface of control.
• Installation and adjustment are readily accomplished with a screwdriver.
• 391937 Conversion Kit changes a (V5306) pressure-regulated natural gas valve to a pressure-regulated LP gas valve.

STARTUP AND ADJUSTMENT

Gas Cock Settings
Refer to gas control instructions.

Pilot Lighting Procedure (standing pilot valves only)

1. Slightly depress Lite-Rite knob if at PILOT position and tum clockwise to OFF. Wait 5 minutes for all unburned gas to vent.
   WARNING
   Remember that liquefied petroleum (LP) gas will not vent upward normally, so forced ventilation may be required for installations below ground level.

2. Tum the Lite-Rite knob to PILOT, depress it completely and light the pilot burner. The knob must be held down about one minute before the pilot burner will stay lit after releasing the knob.

3. Turn the knob to ON, and set the thermostat above room temperature to tum on the main burner.

Gas Leak Test

WARNING
Do not omit this test.

With the main burner in operation, paint pipe joints, pilot gas tubing connections, and valve gasket lines with rich soap and water solution. Bubbles indicate gas leakage. To stop leaks, tighten joints and screws or replace the gasket.

NOTE: Gas leak will affect outlet pressure.

Check Gas Input and Burner Ignition

CAUTION

1. Do not exceed input rating stamped on the nameplate of the appliance, or manufacturer’s recommended burner orifice pressure for size orifice(s) used. Make certain the primary air supply to the main burner is properly adjusted for complete combustion. Follow instructions of appliance manufacturer if provided.
2. IF USING METER CLOCKING METHOD: Make certain there is no gas flow through the meter other than to the appliance being checked. Other appliances must remain off, and the pilot extinguished (or other consumption deducted from the meter reading).
3. IF USING MANIFOLD PRESSURE METHOD: Be sure gas cock is in PILOT or OFF position before removing pressure tap plug to connect pressure gauge (manometer). Also, turn the gas cock back to PILOT or OFF when removing the gauge and replacing the plug. Repeat gas leak test at the plug (the main burner must be operating).

V5306 (standard PRV) Adjustment

1. Check input to the main burner by clocking the gas meter or by using a pressure gauge (manometer) connected to downstream tapping (Fig. 7). The standard natural gas model is factory-set at 3.5 in. wc [0.9 kPa] outlet pressure (nominal), but may vary from 3.2 to 3.8 in. wc [0.8 to 0.94 kPa]. Input can be adjusted from 3 to 5 in. wc [0.74 to 1.2 kPa]. The standard LP gas model is set at 11 in. wc [2.7 kPa] (nominal) but may vary from 10.2 to 11.8 in. wc [2.5 to 2.9 kPa]. Input can be adjusted from 8 to 12 in. wc [2 to 3 kPa]. If adjustment is required, proceed with step 2.
2. Remove cover screw (Fig. 7). Using a screwdriver, turn to adjust screw clockwise  to increase or counter-clockwise to decrease gas pressure to burner.
3. NOTE: Adjustment fitting is plastic and may require slightly greater turning force than metal thread.
4. Replace the cover screw.

V5307 (step-opening PRV) Adjustment

NOTE: Full rate pressure is adjustable-step rate is not.

1. With the main burner operating, check input by clocking the gas meter or check the burner manifold pressure using a pressure gauge (manometer) connected to downstream pressure tapping (Fig. 7).
2. If adjustment is required, remove the cover plug (Fig. 7). Using a small screwdriver, turn to adjust screw clockwise to increase or counter-clockwise to decrease gas pressure to burner. Replace cover plug.
3. Check burner performance at step pressure, observing burner ignition and flame characteristics. The burner should ignite promptly and without a flashback to the orifice, and all ports should remain lit. Cycle burner several times. (Wait 30 seconds between cycles to allow servo regulator to resume step action.) Repeat after allowing the appliance to cool.

V5308 (Hi-LO PRV) Adjustment

The HI or LO flame setting is selected by positioning the white knob (Fig. 8) on the regulator. The burner will operate in the low fire position when the knob is upward; it will operate in the high fire position when the knob is downward.

1. Adjust to LO setting by pulling the knob (Fig. 8) upward to its outermost position.
   NOTE: Turn on the main burner, observing ignition and flame characteristics. The burner should ignite promptly and without a flashback to the orifice, and all ports should remain lit. Cycle burner several times, and then repeat after allowing the appliance to cool.

2. Adjust to the HI setting by pushing the knob (Fig. 8) downward toward the regulator body.

3. Check gas input to the appliance:
   a. With burner operating check gas input by clocking gas meter, or check burner manifold pressure using a pressure gauge (manometer) connected to downstream pressure
   tapping (Fig. 7).
   b. If gas input exceeds nameplate rating, check burner orifice diameter against appliance manufacturer’s specification for gas being used. (The V5308 is not fielded adjustable.)

1. Adjust to LP gas setting as follows:
   a. Remove the cover screw (Fig. 2).
   b. With a small screwdriver, depress and rotate the shaft so the slot is in line with “LP” stamped on the bushing (Fig. 9).
   NOTE: The shaft will remain depressed for LP gas operation.
   c. Replace the cover screw.

2. Adjust to Nat. gas as follows:
   a. Remove the cover screw (Fig. 2).
   b. With a small screwdriver, rotate the shaft so the slot is in line with “N” stamped on the bushing (Fig. 9).
   c. Replace the cover screw.

3.  Check gas input to the appliance:
   a. With burner operating, check gas input by clocking gas meter or check burner manifold pressure using a pressure gauge (manometer) connected to downstream pressure
   tapping (Fig. 7).
   b. If gas input exceeds nameplate rating, check burner orifice diameter against appliance manufacturer’s specification for gas being used. (The V5309 is not fielded adjustable.)

WARNING
At the time of the changeover to other gas, again check gas input alter changing pilot and main burner orifices. Follow the procedure above.
