Install Adapters to Gas Control (if used)

393690-14 Straight Flange (3/4 in.)

쐃

Remove the seal over the gas control inlet or outlet.

쐇

Make sure that the O-ring is fitted in the flange groove.
If the O-ring is not attached or missing, do not use
the flange.

쐋

With the O-ring facing the gas control, align the gas
control threaded holes with the flange clearance holes.

쐏

Insert and tighten the screws provided with the flange.
Tighten the screws to 25 inch pounds of torque to
provide a gas tight seal.

Bushings

쐃

Remove the seal over the gas control inlet or outlet.

쐇

Apply a moderate amount of good quality pipe
compound to the bushing, leaving the two end threads
bare. For an LP installation, use a compound resistant
to LP gas. Do not use Teflon tape.

쐋

Insert the bushing in the gas control and thread the
pipe carefully into the bushing until tight.

Install Gas Control Piping

All pipe must comply with local codes and ordinances or with
the National Fuel Code (ANSI Z223.1 NFPA No. 54),
whichever applies. Tubing installation must comply with
approved standards and practices.

쐃

Use new, properly reamed pipe free from chips. If
tubing is used, ensure that ends are square, deburred,
and clean. All tubing bends must be smooth and
without deformation.

쐇

Run the new pipe or tubing to the gas control. When
tubing is used, obtain a tube-to-pipe coupling to
connect the tubing to the gas control.

쐋

Install a sediment trap in the gas supply line. See Fig. 10.

Fig. 10. Install sediment trap.

Mount Gas Control

쐃

The gas control can be mounted from 0 to 90 degrees,
in any direction including vertically, from the upright
position of the gas control knob.

쐇

Mount the gas control so the gas flow is in same
direction as the arrow on the gas control bottom.

쐋

Thread the pipe as listed in Table 1.

NOTE:

See Table 1 for maximum pipe threading
depth. If the pipe is inserted too deeply into
the gas control, the second main valve or
safety valve can distort or malfunction.

ALL BENDS IN METALLIC TUBING SHOULD BE SMOOTH.

CAUTION:  SHUT OFF THE MAIN GAS SUPPLY BEFORE REMOVING
END CAP TO PREVENT GAS FROM FILLING THE WORK AREA.  TEST 
FOR GAS LEAKAGE WHEN INSTALLATION IS COMPLETE.

쐏

Apply a moderate amount of good quality pipe
compound to pipe only; leave the two end threads bare.
Do not use teflon tape. In LP installations, use a
compound resistant to LP gas. See Fig. 11.

쐄

Remove protective seals over the gas control inlet and
outlet, if necessary.
