Warmworld FFC 30/60 Installation & Service Instructions Manual page 11

Continue running for 15 minutes, venting every 5
minutes.
The Pilot is factory set.
The Main gas valve, GV2, gradually raises the
pressure to the set point. Allow at least 60 seconds
for the final pressure to stabilise.
IMPORTANT. It is essential when setting
the burner pressure that the inlet pressure
is at least 20 mbar with the boiler and any
other connected appliances running.
Set the burner pressure to the correct pressure by
using a manometer connected to the control and
adjusting the regulator to the desired input. (see the
charts below and Fig.1)
Where a bypass is fitted check its operation with the
system hot, the minimum flow rate through the boiler
should be as shown in the Technical Data on
Page1.
Set the pump speed to the highest setting that does
not provoke unreasonable operational noise within
the system.
Sealed Systems only:
pressure and set the gauge indicator
With the system hot, check again for water sound-
ness. Refit the case to the boiler. Add remainder of
corrosion inhibitor. Balance the system in the normal
way to obtain even heating of all radiators.
If fitted set the cylinder thermostat to 60 o C, or lower
if preferred.
Complete the Logbook and pass to the user when
explaining and demonstrate the operation of the
system. Their instructions are located under the
Electrical Tray.
Condensing Boiler
re-pressurise to required
Note: The boiler is fitted with a syphon trap
that includes a blocked drain device. This
is to safeguard the boiler and help defer
the effects from the possible freezing of
the condensate pipework in extreme
weather.
The user should be made aware of this
feature and, that in the event of blocked
condensate pipework, for example frozen
condensate pipework, the boiler will au-
tomatically stop functioning. It will start
again as soon as the blockage has
cleared.
