8.6. CHECKING THE AIR INLET

When an external combustion air
line is connected to the boiler, then
first inspect this line all along its
length to see whether it is clogged.
It is suitable for ensuring whether
the boiler receives
combustion air. All clogging and
deposited materials (for instance,
accumulated dust, etc.) have to be
fully removed. In combustion air
lines, their throats have to be
installed at locations
protected against wind pressure
outside buildings. No dust, toxic or
corrosive gases, steams may be
conducted to these lines.
Warning! / Important!
The exhaust gas line connected to the chimney has to be cleaned with the use of a cleaning
brush. When this cleaning operation is not performed, the removal of combustion products from
the combustion chamber becomes more difficult, which may lead to operation disturbances!

8.7. CHECKING AND CLEANING THE ELECTRICAL PARTS

Again, ensure in advance whether the power supply connector has been unplugged. Check the
laying of the electric cables visually. It is forbidden to conduct cables across sharp edges or
hot places, while cables cannot have cracks or naked surfaces. Cracked or otherwise
damaged cables shall be replaced. When they are strongly dusty, electrical structural elements
have to be cleaned with a brush, and corrosion remains shall be removed from the electrical
contacts as required.

8.8. COMPLETION OF MAINTENANCE WORKS, TEST OPERATION

After the completion of the maintenance works, all the connections shall be inspected, and test
operations shall be carried out.

9. FIRE PROTECTION REQUIREMENTS

Near the boiler, all the combustible building parts, furniture or even ornamental objects
have to be protected against the effects of heat. The locally valid fire protection
provisions and requirements shall be observed at all times.
