GAS SUPPLY
Thegaspipelinecanbebroughtinthroughtherightorleftsideof
the appliance. The insert has a Flexline with shutoff valve located on
the left side when facing the unit. See Figures 16 and 17. Consult
the current National Fuel Gas Code, ANSI Z223.1 CAN/CGA-B149
(.1 or .2) installation code.
