Install Control
1.
This ignition system control can be mounted 0 to
90 degrees in any direction, including vertically,
from the upright position of the ignition system
control switch.
2.
Mount the control so the gas flow is in the direction
of the arrow on the bottom of the ignition system
control.
3.
Thread the pipe the amount shown in Table 7 for
maximum pipe insertion into ignition system con-
trol or adapters. Do not thread pipe too far. Valve
distortion or malfunction can result if the pipe is
inserted too deeply.
4.
Apply a moderate amount of good quality pipe
compound (do not use Teflon tape) only to the pipe,
leaving two end threads bare as shown in Fig. 4. On
LP installations, use a compound resistant to LP
gas.
Table 7. NPT Pipe Thread Length (in.).
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 as shown in Fig. 5 and 6.
Fig. 4. Use moderate amount of pipe compound.
Connect Pilot Gas Tubing
1.
Cut tubing to the desired length and bend as nec-
essary 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 com-
pression 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 as shown in Fig. 6.
4.
Slip the fitting over the tubing and slide out of the
way as shown in Fig. 7.
5.
Push the tubing into the pilot gas tapping on the
outlet end of the control until it bottoms.
6.
While holding the tubing all the way in, slide the fit-
ting into place and engage the threads; then turn
until finger tight.
7.
Then tighten one more turn with a wrench. Do not
overtighten.
8.
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 Sys-
tem flame sense current path. Make sure the
connections are clean and tight for proper appli-
ance operation.
