Cleaning the heat exchanger

NOTICE

Risk of damage to the heat exchanger due to improper cleaning.

▶ Do not use chemical agents to clean the heat exchanger.
▶ Only use one brush with plastic bristles for cleaning.

▶ Cover ignition unit [1].
▶ Remove loose dirt with a vacuum cleaner.
▶ Loosen any other dirt with a brush and remove it with a vacuum

cleaner.

▶ Purge the heat exchanger with water [2].
