BLOWDOWN VALVES

There are three blowdown valves on the boiler, the boiler blowdown valve at the front underside
of the boiler and two water level gauge (sight glass) blowdown valves.
All of these valves must be connected to a blowdown receptacle of approved design.
Regulations exist covering such items and care must be taken to ensure compliance with these
regulations.
If in doubt regarding blowdown arrangements, consult Fulton Ltd or Health and Safety Executive
Guidance Note PM60 which covers blowdown tanks and associated pipework installation.
Never discharge blowdown from the boiler directly to a drain. Where a high level of blowdown or automatic
blowdown systems are installed, serious consideration should be given to fitting a Blowdown After Cooling
