How to drain a Saunier DUVAL boiler and CH system?

How do i drain down a Saunier Duval central heating system? Also how do i refill it? What "chemicals" must i add?

The reason i ask is i suspect there may be sludge in the pipework/radiators and i wish to flush these out.

Any help will be greatly appreciated.

Drain it using several hand grenades obviously from a distance and refill it with unleaded after the dust has settled and light it up using yet another hand grenade.
should also eliminate any sludge problems

Just to add, its a combi boiler, the F30
