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.
