Vokera Gas Diaphragm 3,6 10027159

The Vokera gas diaphragm 3,6 is a flexible diaphragm used within the gas section of the appliance, where it responds to pressure changes to allow the gas valve to modulate or open correctly. It is manufactured by Vokera for the Mynute VHE range of gas boilers. The part is identified by Vokera part number 10027159.

• The boiler fails to light or repeatedly locks out during a demand for heat.
• Burner pressure or modulation is erratic and does not follow the expected range.
• The flame is unstable or the boiler cycles more often than normal.
• The diaphragm is visibly perished, split, stretched or hardened when the gas valve assembly is opened.
• Gas pressure readings at the burner do not respond as expected when the appliance is modulated.

• Confirm the boiler model against the fitment list above, as the diaphragm is specific to the Mynute VHE range.
• Check the diaphragm designation 3,6 matches the one removed from the appliance.
• Inspect the surrounding gas valve components for wear or contamination before reassembly.
• Work on the gas section must be carried out by a competent Gas Safe registered engineer.
