Baxi Pilot Tube 13 To 15 Section S137192

The Baxi pilot tube (section 13 to 15) is a formed metal tube that carries gas to the pilot burner on the appliance's pilot assembly. It is supplied by Baxi under part number S137192 and is listed against the Potterton Derwent Prestige Plus appliance family. The tube runs between the gas valve outlet and the pilot burner, delivering a controlled pilot supply so the flame can be established and proved before the main burner is allowed to fire.

• The pilot flame will not stay lit once the gas valve button is released.
• The pilot flame is weak, unstable or noticeably yellow rather than a steady blue.
• The appliance fails to establish a pilot flame at all during an ignition attempt.
• The tube shows visible kinking, cracking, corrosion or a damaged compression joint.
• A gas smell or a detected leak at the pilot tube connection points.

• Confirm the appliance model and serial number against the compatibility list before ordering, as pilot assemblies vary between appliance variants.
• Check the existing tube's section marking to confirm that the 13 to 15 section length is the correct match for your pilot assembly.
• Note the alternative number 1134566 when cross-referencing against older documentation or stock records.
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
