General information
Offer your customer a maintenance contract covering annual inspection
and servicing work as required. To find out what a contract for annual
inspection and demand-based servicing covers, refer to Chapter 13.7,
page 42.
DANGER: Risk of fatal injury from the explosion of
flammable gases.
▶ Work on gas components must be carried out by
trained and certified personnel only.
Cleaning and maintenance:
If heating oil is being used, cleaning and maintenance must be carried
out twice a year. Depending on demand/run time, a shorter cleaning
interval may be necessary.
Spare parts can be ordered from the Buderus spare
parts catalog.

Why is regular maintenance important?
You should have your customer's system serviced for the following
reasons:
• to achieve a high level of efficiency and to operate the system
economically (low fuel consumption),
• to achieve a high level of operational safety and reliability
• to maintain a clean and environmentally-friendly combustion.
