Product Changes
Diameter and Height Changes
In April 2003 the jacket diameter on all 80 -160L models was reduced from 492mm to
478mm.
In January 2004 the overall height of single and twin element 400L models was reduced
by 40mm. As part of this change the inlet fitting was raised 40mm to maximise delivery
and the height of the booster element was dropped 40mm to retain the same boost
volume.
In May 2004 the 661050 (LH connections) and 671050 (RH connections) models were
replaced with the 691050 dual handed model. The dimensions remained unchanged.
In October 2005 the 691050 was superseded by the 691G50 to meet new MEPS
requirements. As part of this change the diameter increased from 393mm to 437mm and
the height increased from 670mm to 673mm
In March 2006 the 691G50 (dual handed) models were superseded by the 661050F (LH
connections) and 671050F (RH connections). The F series 50 litres have a double plus
cylinder allowing for a reduction in diameter from 437mm to 393mm making the unit more
suitable for in cupboard installation. The overall height however increases from 673mm to
690mm.
Element Changes
In November 2005 a new design electric element and cylinder element barrel was
introduced to all Vulcan electric storage water heaters (refer to fig. 1A & 1B).
The new design elements utilise a new flange, gasket and earthing arrangement and are a
direct replacement for earlier model elements and as such part numbers remain
unchanged.
The new type gaskets (refer to fig.2) will also fit earlier model elements and are now
supplied with the element. These new gaskets have a radius on the top internal edge
allowing a better seal against the element, are shorter overall by 2mm, and have a flange
thickness of 2.15mm instead of 2.25mm.
