INSTALL CONTROL
1. These controls can be mounted O-90 degrees, in
any direction, from the upright position of the gas
cock knob.
2. Install the control so that gas supply is con-
nected to the end provided with projecting boss for
wrench application. See Fig. 1.

2. Slip compression fitting over tubing and slide
out of way. Push tubing into pilot gas tapping on
outlet end of control (Fig. 1) until it bottoms. While
holding tubing all the way in, slide fitting into place
and engage threads - turn until finger tight. Then
use wrench and tighten one turn beyond finger tight.
3. Connect other end of tubing to pilot burner ac-
cording to the pilot burner manufacturer’s
instructions.
WIRING
CAUTION
Never connect these millivoltage controls to
line voltage or to a transformer.
Since the entire system is powered by the
millivoltage generated by the Powerpile
generator, it is important to clean and scrape all
wires before connecting. Solder and tape all
necessary splices using rosin flux to prevent
corrosion. Tighten terminal screws. Total con-
trol circuit wiring must not exceed 30 feet of
2-wire 18 gauge cable, or 50 feet of 2-wire 16
gauge cable.
