When you have completed about 90% of the
element layout, gently unroll the remaining
wire and the second power supply cable
(black) from the spool. At the end point where
the power supply cable meets the heating
element you will find another join. Tape this
join to the
end point
(which is the second
chiselled channel), at least 50mm apart from
the start point join that you taped down
previously.
You will be left with a coil of unsecured
element. This unsecured element should be
laid out in reverse order i.e. starting from the
end point and working backwards to the last
point at which the element was taped down.
In order to achieve even coverage of the
balance of the area to be heated, you may at
this stage need to adjust some of the element
spacing that you previously secured.
This can be achieved by untaping a few of the
previous runs of element that you taped down,
and re-fixing them at wider or narrower
intervals. You may wish to alter the element
layout to fit your particular requirements.
Where there are irregularities of shape you
can lay out the element to provide warmth
around toilets, etc.
