The 325 Series with OPD is suitable for limited horizontal mounting (less than or equal to 90º from upright). But when using the vent limiting device, the regulator must be mounted in a horizontal upright position. Install the regulator properly with gas flowing as indicated by the arrow on the casting (also see the Safety Warning Instructions bulletin). |
NOTE: |
Vent limiters can only be installed in regulators for which they are certified. Vent limiters must only be installed directly into the vent connection of the regulator without intermediate pipe or fittings.
