Adjusting a burner solenoid valve (typically referring to a gas solenoid valve) primarily involves rotating an adjustment screw located on the valve body to control the gas flow rate, thereby adjusting the flame size. The operating procedure is as follows: Ensure the equipment is shut down; rotating the screw clockwise decreases the flow rate, while rotating it counter-clockwise increases the flow rate. Each adjustment should not exceed 1/4 of a turn, and an ignition test should be performed after each adjustment to ensure the flame remains blue and stable.
I. Basic Adjustment Steps
1. Preparation: Ensure the burner is turned off, the main power supply is disconnected, and the equipment is in a safe state.
2. Locate the Adjustment Component: Find the screw used for flow adjustment on the top or side of the solenoid valve body (it is usually covered by an adjustment cap).
3. Adjust the Flow Rate: Use a screwdriver to make adjustments. Clockwise: Decreases the flow rate, making the flame smaller. **Counter-clockwise:** Increases the flow rate, making the flame larger.
4. Fine-tuning Principle: The rotation angle for each adjustment should not be excessive; it is recommended to turn it by \(1/4\) of a turn at a time, then power on the equipment to observe the flame status.
5. Flame Verification: An ideal combustion flame should be blue and stable. If the flame appears yellow or red, or if flame lift-off (detachment) occurs, perform a fine-adjustment in the opposite direction.
II. Adjustment of Special Solenoid Valves (Slow-Opening / Two-Stage) — If using a slow-opening solenoid valve (e.g., the Elektrogas VML series), the adjustment method is as follows:
Initial Opening: Remove the black cap on top and adjust the brass screw located underneath.
Maximum Flow Rate: Adjust the internal set screw located inside the central brass screw (a wrench is required to hold the outer brass screw in place while adjusting).
III. Precautions and Safety Tips
Safety First: During the adjustment process, never violate established gas safety operating procedures.
Coordinate with Air Damper: After adjusting the solenoid valve, it is usually necessary to also adjust the burner's air damper to ensure the proper air-to-gas ratio.
Professional Advice: For complex proportional solenoid valves, it is recommended to have the commissioning performed by a qualified professional to avoid compromising equipment efficiency or causing flashback.
Regular Maintenance: Periodically check the solenoid valve for leaks (seal integrity) and clean any soiled parts of the valve body.
