System Maintenance - IDEAL VANGUARD L 170 Installation And Servicing

37 SySTEm mAINTENANcE

Water Level
Check the water level in the installation regularly, and if
necessary top it up without allowing a sudden inlet of cold
water into the hot boiler.
The operation should only be necessary a few times per
season; if it has to be done more frequently, there is probably
a leak which should be found and corrected without delay.
Safety Devices
Check that safety devices, and particularly the heating circuit
safety valve, are working correctly at regular intervals, and at
least when the boiler is cleaned.

INSTALLATIoN
Draining
It is recommended that an installation should not be emptied
unless absolutely necessary.
For example: when leaving for several months and/or there is
a risk of frost in the building.
In the event of a long shutdown of the boiler we would
recommend the following:
1. The boiler must be fully maintained.
2. IF the boiler is to be isolated during the winter period
then we would advise that the system be treated with an
antifreeze to prevent the heating water from freezing.
Otherwise drain the system completely.
Detail 2:
Fit the pin in the radial hole with a
hammer.
Detail 5:
Withdraw the turbulator.
• Check the water system is correctly filled and free of air.
Air in the boiler could cause damage to the heat
exchanger.
• With the system hot examine all water connections for
soundness.
• Check the gas rate and measure the combustion CO/CO
content.
• Complete the boiler log book.
• Carry out functional checks as appropriate.
Detail 3:
Screw the turbulator remover onto
the turbulator.
Detail 6:
Turn the remover counterclockwise to
release the turbulator.
