Installation, Use and Maintenance
7.2.
Checks on the boiler environment
Before any maintenance operation, a number of common checks should be
carried out on the installation.
• Water pressure: check that the water pressure is greater than 1 bar
when cold.
•
Read the make-up water meter. This operation identifies hydraulic leaks
in the installation. If the consumption of make-up water changes, find out
why and make the necessary repairs.
7.3.
Cleaning the combustion chamber/exchanger
• Cut the electrical power to the boiler,
• Remove the boiler's top cover,
• Close the gas supply,
• Remove the gas supply, the air inlet hose and
the pressure transfer pipe (on the concentric
exhaust adapter side) as well as the burner
connection assembly located on the back of the
control panel.
