11. When discharging condensate into a soil stack or waste pipe
the effects of existing plumbing must be considered. If soil pipes
or waste pipes are subjected to internal pressure fluctuations
when WC's are flushed or sinks emptied then back-pressure
may force water out of the boiler trap and cause appliance
lockout.
12. A boiler discharge pump is available, 'MULTIFIT'
part no. 720648301. This pump will dispose of both condensate
& high temperature water from the relief valve. It has a
maximum head of 5 metres. Follow the instructions supplied
with the pump.
13. Condensate Drain Pipe 'Trace Heating' Elements are
available in various lengths. 'MULTIFIT' part nos.:-
1 metre 720644401
2 metre 720664101
3 metre 720664201
5 metre 720664401*
*Where the drain is between 3 & 5 metres a 5 metre kit can be
used and "doubled back" upon itself.
14. It is possible to fit the element externally on the condensate
drain or internally as detailed in the instructions provided.
15. The fitting of a 'Trace Heating' Element is NOT a substitute
for correct installation of the condensate drain. ALL
requirements in this section must still be adhered to.
