Test for gas leaks

WARNING
9
NEVER TEST FOR GAS LEAKS USING A FLAME
If any leaks are detected, do not proceed past this
step until all leaks have been eliminated.
Leak testing is to be conducted by the installer according
to the instructions given in this section.
Turn on gas. Apply a non-corrosive leak detection fluid to
all joints and fittings in the gas connection between the
shutoff valve and the cooktop. Include gas fittings and
joints in the cooktop if connections may have been
disturbed during installation. Bubbles appearing around
fittings and connections indicate a leak. An electronic
Gas Leak Detector can also be used.
If a leak appears, turn off the supply line gas shutoff
valve and tighten the leaking connections. Retest for
leaks by turning on the supply line gas shutoff valve.
When the leak 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 adjustment is required.
Yellow tips on outer cones:
Normal for LP Gas.
Soft blue flames:
Normal for Natural Gas.
If the flame is completely or mostly yellow, verify that
▯
the regulator is set for the correct fuel. After
adjustment, retest.
Some yellow streaking is normal during the initial start-
▯
up. Allow unit to operate 4 to 5 minutes and re-
evaluate before making adjustments.
