Ideal Burner Cable 174735

The Ideal 174735 is a burner cable supplied by Ideal for use in their commercial boiler range. It carries the electrical signal between the appliance's control board and the burner assembly, so the ignition sequence and burner operation depend on it being sound. Cables of this type sit in a hot, vibrating environment, and the connectors and insulation are the parts that usually degrade first.

• The burner fails to light, or ignition is intermittent rather than consistent
• The appliance locks out shortly after a call for heat, with ignition-related fault codes
• Visible damage to the cable: cracked, brittle or heat-hardened insulation, or exposed conductors
• Loose, corroded or heat-damaged terminals at either end of the cable
• Faults that move or disappear when the cable is disturbed, suggesting a broken conductor inside the sheath

• Confirm the appliance model and GC number against the compatibility list, as Ideal used different burner cables across its commercial range
• Check the existing cable's part number or the alternative number 1780538 against the one fitted, particularly if the appliance has been serviced or repaired previously
• Inspect the burner gasket and any seals disturbed during removal, and replace them if they are compressed or perished
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
