Application

A single dose of Fernox Cleaner F3 265ml is suﬃcient to clean an average domestic heating system of 100 litres, up to 12 radiators, or 190 sqm of underﬂoor heating. Additional / repeat applications of Cleaner F3 may be necessary for larger systems, or if systems are heavily sludged. Alternatively, Power Cleaner F8 may be used for heavily sludged systems.

First drain and reﬁll the entire system with plain water. For optimum results the entire system, including drop feed radiators where ﬁtted, should be completely drainable. Preferably, full bore gate valves with hose connectors should be provided temporarily for this purpose. Motorised and thermostatically controlled valves must be set so that no part of the system is closed off during cleansing, or rinsing. Discharges must be made to the foul drain and not the surface water drain. For open vented systems add Cleaner F3 via the header tank. For sealed systems add via a suitable dosing point, or use Fernox Cleaner F3 Express 400ml.

Fernox Cleaner F3 can also be used in conjunction with a powerﬂushing unit. In this case, please refer to the unit manufacturer’s instructions. When pre- commission cleansing new systems, Fernox Cleaner F3 should be circulated for a minimum of one hour at normal operating temperature. For cleaning existing systems, sludge and debris should be dispersed also within one hour at normal operating temperatures. However, to remove hardened iron oxides and limescale, the cleaning time can be extended to up to one week under the normal heating cycle. If a radiator still has a cold spot after one hour, increase the ﬂow through the radiator by closing the valves on the other radiators.

An additional or repeat dose of Cleaner F3 may be necessary in some cases. Drain and ﬂush thoroughly, at least twice, until the water runs clear. When using Cleaner F3 with a powerﬂushing machine, cleaning should be completed within an hour. Use dynamic ﬂushing with plain water until the water is clear. Reﬁll the system adding Fernox Protector F1 for long term protection against corrosion and limescale. In single feed indirect cylinders, e.g. “Primatic” or similar, potable water chemicals must be used.

“Cleaning a central heating system using Fernox F3 Cleaner and protecting with Fernox F1 Protector can restore and maintain system eﬃciency, resulting in a gas saving of up to 15% every time you heat your room. This saving is equivalent to 110 Kg CO2e per typical home per year.”
