REPLACING ASHING ELEMENTS   

Once Silicon has dried, using two sets of pliers 
bend tails towards the centre of the furnace. 
You will need to bend to just over 90 Deg. 

Measure 50mm from centre of bend 
and cut excess tail off.  

NOTE:

 if you unwind the excess wire 

from the tails into two single bits of 
wire, you can use this to make ele-
ment pins if having issues with ele-
ments sitting flat. Bend to a U shape 
pin about 30mm long. 

Reinstall element tails into porcelain connectors. 

Once all have been reinstalled (before attaching 
back panel to furnace) turn on the furnace for 
one hour to anneal elements. 

Once elements have been annealed, check to 
see if elements are sitting correctly in grooves. 
Isolate power and check tightness of element 
tails in porcelain connectors, as the wire can be-
come loose as it softens. 

Once this has been checked replace back cover.
