Vitoflex 300-UF Service & Maintenance
Cleaning
(continued)
Flue gas re-circulation system (optional)
WARNING
A mixture of emissions and air that may contain carbon
monoxide (CO) and other toxic odorless gases is produced
inside the re-circulating flue gas piping system. Its pressure
is slightly above atmospheric.
Therefore the correct assembly of the cleaning lids must
be checked and the system must be checked for leaks
each time the system has been cleaned (when the
re-circulating flue gas exhaust blower is in operation and
the flaps are closed, no gas may escape).
Approx. every 4000 operating hours:
Clean the secondary air blower.
Approx. every 1000 operating hours:
Clean the re-circulation flue gas exhaust blower.
After around 1800 operating hours (annually):
Checks for leaks must be repeated each year
so that any possible wear on the seals,
particularly in the area of the maintenance
covers, may be recognized and corrected in time.
Approx. every 4000 operating hours:
Clean the re-circulation flue gas line
RISK OF INJURY: Shut the system off before starting
any cleaning. Be absolutely sure to wear protective
gloves, protective eyewear if required and use the
cleaning tools that come with the system (danger
of blow-ups, burns and getting crushed)!
