Gas Connections

Figure 3-9 is an illustration of the Gas Connector Panel. Optional gas

connections are shown in shaded blocks.

The unit is manufactured with

1

/

4

inch tube fittings only. Adapters must

be used for metric tubing. (At least 6 mm is recommended.)

For a safe connection:

1. Insert the tube into the tube fitting, and finger-tighten the nut until

the tubing cannot be rotated freely, by hand, in the fitting. (This
may require an additional

1

/

8

turn beyond finger-tight.)

2. Hold the fitting body steady with a backup wrench, and with

another wrench rotate the nut another 1

1

/

4

turns.
