Install Piping to Control
All piping must comply with local codes and ordinances
or with the National Fuel Gas Code (ANSI Z223.1, NFPA
No. 54), whichever applies. Tubing installation must
comply with approved standards and practices.
1.
Use new, properly reamed pipe that is free from
chips. If tubing is used, make sure the ends are
square, deburred and clean. All tubing bends must
be smooth and without deformation.
2.
Run pipe or tubing to the ignition system control. If
tubing is used, obtain a tube-to-pipe coupling to
connect the tubing to the ignition system control.
3.
Install a sediment trap in the supply line to the igni-
tion system control. See Fig. 3.
Install Control
1.
Mount 0 to 90 degrees in any direction, including
vertically, from the upright position of the ignition
system control switch.
2.
Mount 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 6 for
insertion into ignition system control or adapters.
Do not thread pipe too far. Valve distortion or mal-
function can result if the pipe is inserted too
deeply.
Table 6. NPT Pipe Thread Length (in.).
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. 4.
Fig. 3. Sediment trap installation.
Fig. 4. 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. 5.
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 (Fig. 6). Slip the fitting over the tubing
and slide out of the way. See Fig. 7.
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, then turn until
finger tight. Tighten one more turn with a wrench,
but do not overtighten.
