Installation Instructions
When the thermostat is calling for heat, 230V is supplied
to terminals 10 and 11 on the control box and tab 1 and 2
on the fan, energizing the fan.
There will then be a short delay while the control box
checks that the fan is running and pre-purges. Providing
there is gas to the burner, combustion should be
established after approximately 30 seconds.
On first firing after installation or servicing, the burner may
go to lock out, until all the air has been purged out of the
burner. Wait at least 10 seconds before pressing the reset
button. (See Fig. 8).
Check gas cock is in the on position.
Check inlet gas pressure at test point.
Check to ensure electrical safety is carried out by a
competent person.
For safety purposes, a combustion discharge safety
device is fitted. This will only operate under adverse flue
conditions. If the switch has been operated, it should be
pushed in to reset. If this problem persists, contact your
local engineer to determine and rectify the cause. It is
important not to reset more than once as this may indicate
a flue blockage.
WARNING:
The combustion discharge safety device
must not be interfered with or rendered inoperative, as
this could interfere with the safe operation of the
appliance and invalidate the appliance warranty.
