Connect Pilot Gas Tubing
1. Cut the tubing to the desired length and bend as
necessary for routing to the pilot burner. Do not make
sharp bends or deform the tubing. Do not bend the
tubing at the control after the compression nut has
been tightened because this can result in gas leakage
at the connection.
2. Square off and remove the burrs from the end of the
tubing.
3. Push the tubing into the compression nut clearance
hole until the tubing bottoms.
NOTE: When replacing a pilot burner or orifice, cut off
old compression fitting and replace with the
new compression fitting provided with new
pilot burner. Never use the old compression
fitting because it may not provide a gas-tight
seal. See Fig. 19.
4. While holding the tubing all the way in, engage the
threads and turn until finger tight.
5. Using a wrench, turn the compression nut one turn
beyond finger tight. Do not overtighten .
