Condensate pipe and traps

The full length of the condensate pipe
should be check for leaks.
The boiler has a built-in condensate trap
provided with a ball valve that prevents the
escape of combustion products when the
trap is empty.
It is however recommended that any oth-
er trap in the drain system is correctly
filled with water before to run the boiler.
Fill the built in condensate trap
by removing the flue elbow and
pouring a cupful of water into
the flue outlet (Fig. 7.5).

Lighting the boiler

Some products incorporate an anti cycling
time delay. It is normal when first switch-
ing the boiler on for the boiler to operate on
heating for a few seconds then switch off.
After 3-4 minutes has elapsed the boiler will
then re ignite and operate perfectly normal-
ly. The ignition delay cycle does not prevent
normal operation of the boiler to provide
d.h.w.
If external controls are fitted (e.g. Timeclock,
room thermostat) ensure they "call for heat".
• Turn on the electricity supply to the boil-
er, switching on the fused spur isolation
switch. The appliance operation light 10
will flash every 4 seconds.
• Turn the function selector 8 as in Fig. 7.7.
The appliance operation light 10 will flash
every 2 seconds.
