Hamworthy Venturi Medium Size 532418007

This is a medium size venturi supplied by Hamworthy as a replacement component for their appliances. The venturi sits in the air and gas pathway, where its tapered bore and throat create the pressure drop that draws gas into the airstream and holds the mixture at the ratio the burner needs. It is a small but critical part of the combustion circuit, and its internal profile has to be matched to the appliance it is fitted to.

• The appliance runs with an unstable or lifting flame, or the burner fails to light cleanly
• Combustion readings drift outside the expected range and cannot be corrected by adjustment
• Soot deposits or discolouration appear around the burner or heat exchanger
• The venturi body is cracked, distorted or has a damaged sealing face
• Debris, corrosion or a build-up of deposits has narrowed or blocked the venturi throat

• Confirm the appliance model and serial number, and match them against the compatibility list below, before purchasing
• Compare the number stamped or printed on the existing venturi with 532418007 and 45900450 to be sure you are replacing like for like
• Inspect any seals, gaskets or O-rings disturbed during removal and replace them if they are perished or compressed
• Work on the combustion circuit of a gas appliance should only be carried out by a competent, registered engineer
