Ideal Combustion Chamber 170265

The combustion chamber is the enclosed metal section where the gas burner flame is contained and where heat transfer to the appliance's water circuit begins. This unit is supplied by Ideal for its Commercial range of boilers and is listed under part number 170265. It forms part of the combustion assembly on Viceroy GT and GT10 appliances, so it is a gas-carrying component that must be fitted and commissioned by a competent engineer.

• Flame picture is unstable, with lift, roll-out or a visibly disturbed burner flame.
• Soot deposits or heavy discolouration on the chamber walls or baffles.
• Corrosion, cracking or distortion of the chamber panels after prolonged heat cycling.
• Flue gas readings drifting outside the expected range during a service or combustion analysis.
• A rising carbon monoxide reading on a flue gas analyser, or a CO alarm activating near the appliance.

• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
• Confirm the appliance model and serial number against the compatibility list before ordering.
• Check the old part number 82290532 and the alternative number 1177498 against the unit being replaced.
• Inspect the chamber seals, gaskets and fixings on the appliance and order any that are due for renewal at the same time.
