Fig. 1-Two-Stage Gas Valve The major difference in the two-stage G valve, besides the compact design, is the location of the Low and High stage regulators. Both regulators are located on top of the valve and are marked “Lo ” and “Hi ” next to the regulator seal caps. Both regulator springs are adjusted with a standard 3/16 ” or smaller flat-tipped screwdriver. The other difference is the G series valve IS NOT a dual-fuel gas valve.
