B. SECURING REFRIGERATOR IN ENCLOSURE

The refrigerator is installed in the enclosure with eight screws. Six screws are in the front frame and two are in the plate on the rear. See FIG. 5.

FIG. 5

NOTE: Push refrigerator into enclosure until front frame is tight against the cabinet. First, secure the frame to cabinet with six screws. Second, install the two screws to the floor at the rear of the refrigerator.

Failure to follow the sequence in securing the refrigerator in the enclosure can cause leakage between the frame and cabinet. Any space between the counter, storage area or ceiling and top of the refrigerator should be blocked. The heat produced at the rear of the refrigerator will become trapped in this space, making the top of the refrigerator hot and reducing the efficiency.

The dimensions shown in FIG. 3 will give you adequate space for service and proper installation.

8. GAS CONNECTION

Hook-up to the gas supply line is accomplished at the manual gas shutoff valve, which is furnished with a 3/8" SAE (UNF 5/8" - 18) male flare connection. Always use a backup wrench when connecting the gas supply line to the gas inlet fitting. All completed connections should be checked for leaks with a noncorrosive leak detector. (See FIG. 6 - Gas inlet fitting may have a different orien- tation than shown).

! WARNING

DO NOT use a flame to check for gas leaks.

When testing the gas supply system at test pressures in excess of 1/2 psig, the refrigerator and its individual shutoff valve must be disconnected from the gas supply piping system.

When testing the gas supply system at pressures less than or equal to 1/2 psig, the appliance must be isolated from the gas supply piping by closing its individual manual shutoff valve.

In case detailed instructions on the installation and connection to the gas supply are required, contact your dealer or distributor.
