Boiler Noise Silencer F2 500ml

Application, Fitting & Dosing

A single dose treats a larger sized property with a heating system of 130 litres, up to 16 radiators, or 250 sqm of underfloor heating. Too much treatment will not cause problems and is preferable to insufficient dosing. Severe noise may require more than one application. For open vented systems add via the header tank. For sealed systems add via a suitable dosing point (e.g. a towel rail, or an in-line system filter). Alternatively, use a suitable dosing vessel to inject the product into the system. For long term protection against corrosion and limescale we recommend systems are cleansed using Fernox Cleaner F3 and then protected with Fernox Protector F1. In single feed indirect cylinders, e.g. ‘Primatic’ or similar, potable water chemicals must be used.
