Check Manifold Gas Pressure; Final Check; Before Calling Service - Bosch NGM5455UC Mode D'emploi

check is complete (no bubbles appear), the test is
complete. Wipe off all detection fluid residue.

Check Manifold Gas Pressure

During any pressure testing of the gas supply piping
system at test pressures greater than 14" of water column
pressure (approximately ½" psig, 3.5 kPA) it is necessary to
disconnect the cooktop and its individual shut-off valve
from the gas supply piping system.
If it should be necessary to check the manifold gas
pressure, connect a manometer (water gauge) or other
approved gas pressure reading device to the top burner
right rear orifice. Using a rubber hose with inside diameter
of approximately 1/4" hold tubing down tight over orifice.
Turn burner valve on.

Final Check

After conversion is complete, place each correct sized
burner cap in its seated, notched position and check the
operation of the electric igniters. Check flame
characteristics. Flame should be blue with a minimal yellow
tip on the outer cone of the flames.
Check Flame Characteristics
Yellow flames:
Further adustment required.
Yellow tips on outer
cones:
Normal for LP Gas.
Soft blue flames:
Normal for Natural Gas.
Note: If the flame is mostly yellow, verify that the regula-
tor is set for the correct fuel. If adjustment is neces-
sary, retest the system.
Some yellow streaking in the flame is normal during the
initial start-up. Allow the unit to operate 4 to 5 minutes and
then re-evaluate before making further adjustments.
