1. Remove the pilot gas seal (plug).
2. Cut tubing to desired length and bend as necessary
for routing to pilot burner.
CAUTION
Do not kink tubing.
1. Do not make sharp bends or deform the tubing.
2. Do not bend tubing at the gas control or pilot
burner after compression fitting has been
tightened because this can result in gas
leakage at the connection.
3. Square off and remove burrs from end of tubing.
4. Use the compression fitting supplied with this gas
control. Slip the fitting over the tubing and slide out
of the way.
NOTE: When replacing a gas control, cut off old com-
pression fitting and replace with the new com-
pression fitting provided on the gas control.
Never use the old compression fitting because it
may not provide a gas-tight seal.
