START-UP: CHECKING PROCEDURE
CHECKS BEFORE COMMISSIONING:
• That the burner is assembled in
accordance with the instructions given
here.
• That the burner is pre-set in accordance
with the values in the adjustment table.
• Setting the combustion components.
• All electrical connections must be correct.
• Check the burner motor for correct
direction of rotation.
• The heat generator must be ready for
operation, and the operating regulations
for the heat generator must be observed.
• The heat generator and heating system
must be filled with water and the
circulating pumps must be in operation.
• The temperature regulator, pressure
regulator, low water detectors and any
other safety or limiting devices that might
be fitted must be connected and
operational.
• The exhaust gas duct must be
unobstructed and the secondary air
system, if available, must be operational.
• An adequate supply of fresh air must be
guaranteed.
• Make a test of the all gas-carrying
elements for absence of leaks.
• With burner in starting position check that
air damper is in "CLOSED" position.
• Check that automatic furnace controller is
unlocked and in its original position.
• A standard-compliant measuring point
must be available, the exhaust gas duct up
to the measuring point must be free of
leaks to prevent anomalies in the
measurement results.

GAS START-UP
• Connect the measuring instruments for
the gas head pressure on the test
connection downstream of the gas damper
and the air pressure on the burner test
connection.
• Open the gas shut-off valve before the
gas-armatures and test the gas pressure
on the pressure gauge
• Set the "Manual-Automatic" selector
switch to "Manual".
If the valves are tested for absence of
leaks, this should be continued until a
positive result is obtained. If a valve is
found to leak, the program will not step
forward to the automatic furnace controller.
The burner will start according to the
program flow of the see control box.
Prior to the initial fuel feed start make
a functional test of the burner program
flow:
Gas system:
• Shortly open the gas shut-off valve in the
valve group until pressure is available
and close again.
• Start burner and check program flow for
correct start-up sequence:
1. Fan.
2. Pre-ventilation damper.
3. Check air pressure.
4. Partial-load damper.
5. Ignition.
6. Valves open.
7. Safety lock-out after expiry of
safety period (see control box) or shut-off
because of gas supply failure.
• Unlock the see control box.
