Ideal Injector Kit 3.75mm 177155

The Ideal Injector Kit 3.75mm is a replacement injector assembly supplied by Ideal for use in its commercial appliance range. The injector meters and directs the gas and air mixture into the burner, so its bore size has a direct effect on combustion quality and flame stability. This kit is identified by part number 177155 and uses a 3.75 mm injector size.

• The burner fails to light, or lights inconsistently across the appliance's operating range
• A weak, yellow or lifting flame is visible at the burner
• Soot deposits or heat discolouration appear around the burner or heat exchanger
• Combustion readings drift outside the appliance's stated tolerance
• The injector is visibly blocked, corroded or damaged when inspected

• Confirm your appliance model against the compatibility list before ordering.
• Check that the existing injector size matches the 3.75 mm bore of this kit.
• Cross-reference the alternative part number 1782567 when working from older documentation or parts lists.
• Inspect the surrounding burner components at the same time, as injector faults often accompany other combustion-related wear.
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
