4. Apply a moderate amount of good quality pipe
compound (do not use Teflon tape) only to the pipe,
leaving two end threads bare. On LP installations,
use a compound resistant to LP gas. See Fig. 3.
Fig. 3. Use moderate amount of pipe compound.
5. Remove the seals over the ignition system control
inlet and outlet, if necessary.
6. Connect the pipe to the ignition system control inlet
and outlet. Use a wrench on the square ends of the
ignition system control. If a flange is used, place the
wrench on the flange rather than on the ignition
system control. Refer to Fig. 4 and 5.

Connect Pilot Gas Tubing
1. Cut 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 ignition system control after
the compression nut is tightened, because this can
result in gas leakage at the connection.
2. Square off and remove burrs from the end of
the tubing.
3. Unscrew the brass compression fitting from the pilot
outlet (Fig. 4). Slip the fitting over the tubing and
slide out of the way. See Fig. 6
4. Push the tubing into the pilot gas tapping on the
outlet end of the control until it bottoms. While
holding the tubing all the way in, slide the fitting into
place and engage the threads—turn until finger tight.
Then tighten one more turn with a wrench. Do not
overtighten.
5. Connect the other end of the tubing to the pilot
burner according to the instructions supplied with
Q3450/Q3480.
NOTE:
The pilot tubing provides the SmartValve System
flame sense current path. Make sure the
connections are clean and tight for proper
operation.
Fig. 6. Always use new compression fitting.
