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