Broag Gasket Set Engine (Set 1+2+3) 720404701

The Broag Engine Gasket Set (Set 1+2+3), part number 720404701, is a sealing kit for the engine assembly of Broag commercial boilers. It combines three gasket sets into a single pack, covering the sealing points required when the engine assembly is stripped and rebuilt. The gaskets restore a gas-tight and water-tight seal at the joints they serve.

• Visible water or coolant weeping from joints around the engine assembly
• Combustion gas traces or flue gas smell at gasket faces after reassembly
• Gaskets that are brittle, flattened, cracked or stuck to the mating faces on strip-down
• Repeated pressure loss or overheating traced to a failed seal on the engine assembly
• Gasket faces disturbed during a burner, engine or heat exchanger service

• Confirm the boiler model and serial number against the manufacturer's parts list
• Check that the engine assembly on your appliance uses the three-set arrangement covered by this kit
• Inspect the mating faces for corrosion or pitting before rebuilding, as damaged faces will not seal
• Have the manufacturer's torque figures and fitting sequence to hand before starting the job
