Theuediametermustbethesameorlargerthantheboilerueoutlet.Areductioninue
diameter will cause additional resistance which could have an adverse effect on combustion.
Note: Avoid tting 90° short radius elbows, 90° tees and long horizontal runs wherever possible.
Note: All horizontal ue runs should have a rising pitch of 15° minimum to prevent condensate build-up and
subsequent corrosion.
Note: Oil-red boiler installations are generally more critical because of the sulphur content in the fuel and the
higher dew-point temperature.
Note: Specialist advice should be obtained on ue material and insulation.
