SILVER M
INSTALLATION – OPERATING - MAINTENANCE
5.14.
Direct lighted heat exchanger (burner
chamber in the airstream)
General
In order to avoid skin burns, do not touch hot surfaces. Observe
safety related regulations.
Install and connect the oil or gas burner in accordance with the
manufacturer's instructions.
Every system must be outfitted with an Emergency-Stop switch.
Overheating damage can result from system operation without
sufficient cooling or when emergency system shutdown is initiated
by the safety system. For this reason, the Emergency-Stop switch
should be used only for the protection of persons. We cannot accept
responsibility for damage resulting from Emergency-Stop actuation.
Give heed, as far as possible, to the uniform intake and exhaust
flows through the burner chamber. The adjustable covering plates
might have to be adapted in order to avoid heat build-up or
temperature stratification.
Commissioning
Undertake the assembly and wiring of all sensors and thermostats.
Check flame propagation; do not make contact with burner chamber
walls. Use a flame head extension or another nozzle angle.
Undertake connection of the chimney. This must be carried out in
accordance with technical construction and official regulation.
Establish operational readiness:
Bleed oil or gas lines
-
Thermostat ventilator: Rated value ca. 40 °C
-
Temperature monitor: Rated value ca. 75 °C
-
Safety temperature limiter - burner: Rated value ca. 100°C
-
(These values apply only to standard system designs with a supply
air temperature of 60°C. For higher supply air temperatures, the
manufacturer's specifications must be observed.)
Bring burner into service. The manufacturer's commissioning
instructions must be precisely adhered to. For this, it must be
ensured that the ventilator is continually operating. The fuel intake
must be adjusted so that the equipment rated performance is not
exceeded. For gas burners, it is highly recommended that a gas
meter be used.
Determine exhaust gas value.
Maximum exhaust gas temperature: ca. 210°C
-
Minimum exhaust gas temperature: ca. 150°C
-
All setting values are to be recorded and archived in the setting
adjustment protocol.
Use of a condensation separator is permitted only during the run-in
phase. Adjust the exhaust gas temperature to the allowable range
by adapting the turbulators (removal of the turbulators raises the
exhaust gas temperature).
Condensate accumulation should be disposed of according to local
directives.
Maintenance
Burner chamber
Dismantle the burner chamber. Using a suitable light source,
-
check the burner chamber for contamination, damage and
leakage. Damaged burners must not be put into service.
After cleaning the downstream heating surfaces, vacuum clean
-
the burner chamber.
Flame pan
Check the flame pan for damage. In the event of damage or
-
deformation, restore or replace. For this, the burner plate and
the cylinder cover must be dismantled.
Downstream heating surfaces
Remove the inspection cover plate and cleaning cover from the
-
burner chamber. Remove all turbulators and check for general
condition. In case of heavy corrosion, replace individually or
completely.
Clean all downstream heating surface pipes with a stainless
-
steel brush and vacuum clean the collector tank.
Check the de-watering unit and clean as necessary.
-
Burner
Subsequent to cleaning the burner chamber, service and
-
maintenance of the burner is to be carried out in accordance
with manufacturer's directives.
Determine exhaust gas value.
-
All work tasks are to be recorded in the protocol.
-
Check gas lines, connections and the gas control path for leak-
-
tightness; re-seal as necessary
Check regulating and safety devices
-
Check bypass and burner chamber dampers
-
