1.1 In Operation
The Potterton Promax SL is a range of high efficiency
condensing boilers.
In common with other condensing boilers its exceptional
efficiency means the flue gases are cooled to such an extent
that steam is often visible at the outside flue terminal.
The amount produced depends on system design, product use
and outside air temperature but it is not harmful to the
individual or the working of the boiler in any way.
Other Controls
A Potterton Electronic Programmer or other type of clock
should have been fitted in your system, together with heating
and hot water controls. Full instructions on the use of these
controls will have been supplied with them.
1.2 To Light
1. Ensure that the main gas and electricity supplies to the boiler
are ON.
2. The fan will start to run and after a short period the ignition
spark will commence. Sparking will continue until the flame is
established then stop automatically. Check that a flame is
visible through the sight glass.
