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.
