Beforegoingintothesubjeels of maintenanceand
koubleshootiag,we wouldliketoprovidea brief
descriptiononlhe fu_lional unitsofthegasequipment,
whichwillmakefor a better understandingofthese items.
6.1 The gas equipment (Fig. D)
The gasconnector(D14) isconnectedto a manualshut
offvalve (D13),normally"to be left open(handtein

Thevalve(D13)isconnectedto thecombinationcontrol
valve(seefollowingitem) bya union(D15).
If the Refrigeratoristo be remoeedfor maintenanceor the

To tightIha burner, it is necessary to keep the gas supply
open manually, by depressing (G3), until the flame
ignite& Within 3 to 4 seconds,the frame will heat the
thermocouple (H1) enough Io bold the gas passage
open.
