Midco J83-DS - Manual (Page 4)

„ A suitable Main Gas Pressure Regulator should be installed as shown in Figures 1 or 2
Choose a regulator(s) to adjust the available gas pressure to the pressure shown in SPECI-
FICATIONS, page 2.
CAUTION: The regulated gas pressures must not exceed 14"W.C. or Main
Automatic Gas Valve and Ignitor Regulator will be damaged. If excessive gas pressure
is prevalent, the regulator must be a tight shut-off type to prevent high pressures from
developing during stand-by.
