מִבצָע

The Durablow DV970A-NG valve features a manual control dial with three positions:

OFF In this position, the gas supply to both the pilot and main burner is completely shut off.
טַיָס: This position allows gas to flow only to the pilot burner. Use this setting for lighting the pilot. Once the pilot is lit and established, hold the dial in this position for a short period (refer to your appliance's manual for exact timing) to allow the thermopile to generate sufficient millivoltage.
עַל: Once the pilot is lit and the thermopile is generating adequate power, turn the dial to the "ON" position. This allows gas to flow to the main burner when called for by the thermostat or remote control system.

For detailed instructions on lighting your specific appliance, refer to its owner's manual.

תַחזוּקָה

Regular maintenance ensures the longevity and safe operation of your gas valve. All maintenance should be performed by a qualified service technician.

בדיקה שנתית: Have a qualified technician inspect the gas valve and all gas connections annually for signs of wear, corrosion, or leaks.
ניקוי: Keep the area around the gas valve clean and free from dust, debris, and obstructions. Do not use harsh chemicals or abrasive cleaners on the valve.
Pilot Assembly: Ensure the pilot assembly is clean and the pilot flame is strong and blue. A weak or yellow pilot flame may indicate a problem with the gas supply or pilot orifice.
