Connect Pilot 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
because this can 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. 3). Slip the compression fitting over the tubing and
slide out of the way.

NOTE: When replacing a entire gas control, cut off old

compression fitting and replace with the new compres-
sion fitting provided on the gas control. Never use the
old compression fitting because it may not provide a
gas-tight seal.

4. Push tubing into the pilot gas tapping on the outlet

end of the control until it bottoms. While holding tubing all
the way in, slide compression fitting into place, engage
threads and turn until finger tight. Then tighten one more
turn with wrench. Do not over tighten. Refer to Fig. 5.

5. Connect other end of tubing to pilot burner according

to pilot burner manufacturer instructions.

QUICK
CONNECTS

All wiring including insulated quick connect terminals

must comply with applicable electrical codes and ordinances.

Disconnect power supply before making wiring connec-

tions to prevent electrical shock or equipment damage.

1. Check the power supply rating on the gas control and

make sure it matches the available supply. Install trans-
former, thermostat, and other controls as required.

2. Connect control circuit to gas control terminals. See

Figs. 3 and 6 or 7.

3. Adjust thermostat heat anticipator to 1.4A rating

stamped on gas control.
