ken care of:
•
The boiler should be located in a dry space.
• The boiler should always be operated within the recommended limits.
• The boiler should be cleaned up when the flue gas temperature has risen 20–30°C above
that of a clean boiler.
• If any part is damaged, it must be replaced with a new one as early as possible.
• Check that condensation water or water from pipe leaks cannot damage the boiler.
