5.5 Combustion gas bypass (code EHP-B)
Combustion gas bypass (code EHP-B)
The purpose of the combustion gas bypass is to reroute the air flow in the event
of a fire. Faulty function gives rise to disturbances that may result in serious
problems.
Inspection
1. Check the function of the damper actuator.
2. Check that damper tightens when closed, follow point 3 under "Combustion
gas bypass, commissioning" on page 17. If they are not sealed, adjust the
damper actuator to make the damper tight.
3. Check the sealing strips.
4. If the damper is not working, check that there are no screws penetrating the
drive mechanism/damper blades to interfere with damper function.
Cleaning
Vacuum and/or wipe all surfaces with a damp cloth. If more intense cleaning is
needed, do so with rotating nylon brushes.
