outlet should be at least 1 metre higher than the nearest ridge to avoid down draughts. Where a
chimneycowlistted,careshouldbetakentoensurethatthedistancebetweenthelowestpoint

cone type.
Note: If the ue layout is such that it may produce an excessive up-draught, a draught stabiliser may be required.
Note: Avoid tting 90° elbows whenever possible, if unavoidable compensate by increasing the ue diameter.
Note: Ensure all ue pipes from the boiler to the main ue have a rising pitch.
2.4.2 BLOWDOWN VALVES
There are six blowdown valves on the boiler, two main boiler blowdown valves at the bottom of
the boiler, two water bottle blowdown valves 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.
WARNING
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ttingaBlowdownAfterCooling
