Carrying Out A Tightness Test In Operating Conditions - Buderus GB142-60 Instruction

Read out the differential pressure.
The differential pressure (p
-0.02 inch W.C. (- 5 Pa) (±0.02 inch W.C. = ± 5 Pa)
(read-out on pressure gauge: -0.04 – 0 inch W.C. =
-10 – 0 Pa).
Enter the value measured in the start-up report.
If the gas/air ratio is not correct it can be adjusted
using the adjustment screw (fig. 8, pos. 1). The
adjustment screw is located behind the cover screw.
Repeatedly press the "Service"
temperature indication is displayed.
Press the "Chimney Sweep"
imal point is cleared from the display.
Switch off the heating system using the main switch.
Remove the measurement set-up, tighten the screw

Switch on the heating system using the main switch.
3.4 Carrying out a tightness test in
operating conditions
Check all gaskets and joints in the burner gas circuit
for leaks while the burner is operational, using a
foaming agent.
DANGER !
Leaks may be caused to pipes and screw
connections during start-up activities if
flammable gas explodes.
– Only use approved leak detection
agents for leak detection such as a
soapy water solution.
CAUTION
due to a short circuit.
– Cover damageable parts before leak
testing.
– Do not spray the leak testing agent onto
cables, plugs or electrical connection
lines. Do not allow it to drip onto them
either.
