• Check that water is circulating correctly. Balance the radiators to ensure that the flow and return
differential does not exceed 20°C.
• Check that when operating in the "Winter" mode, the pump stops and domestic hot water is produced
correctly when the hot water tap is turned on.
• Check that in the "Summer" mode, the burner lights up and shuts down correctly when the domestic
hot water tap is turned on and off.
• Check that the domestic hot water flow and ∆T correspond to the table. Do not rely on empirical
measurements. Temperature should be measured using thermometers as near as possible to the boiler,
bearing in mind the heat loss from the pipes.
• Check that the gas valve modulates correctly both during the central heating phase and the domestic
hot water production phase.
• Determine the combustion efficiency and the composition of the flue gases (refer to 8.04)
• If any of the above are not correct refer to Technical Data (page 5). Adjustment (page 41) and
Troubleshooting (page 58).
