Maintenance Instructions

TRIGON L Condensing Boiler
Maintenance and cleaning must be
performed by trained and authorized
personnel only. Said personnel shall
bear all responsibility for their
proper implementation.
Measurement and assessment of
specified emission values
Turn off heating main switch, and
secure against accidental turning on,
or separate all poles of equipment
from power lines
Turn off gas valve
Dismount equipment panels
Disassemble blower, gas valve, and
burner unit
Remove ignition cable. Check ignition

ter (remove stubborn dirt accumulati-
ons with a thin plastic brush, then
rinse)
Clean out siphon and fill with water

nitor (10 mbar), if necessary
Check all condensate-bearing parts
for leaks. Remove any leaking con-
densate or other moisture.
Check all fastener bolts, replace if
necessary
Check system pressure, expansion
