6.13 — Low Gas Pressure Switch
Adjust the scale setting to slightly below the normal burning pressure. The control circuit will be broken when
pressure falls below this point. Since gas line distribution pressure may decrease under some conditions, shut-
downs may result if the setting is too close to normal. However, regulations require that the setting may not be
less than 50% of the rated pressure downstream of the regulator. Manual resetting is necessary after a pressure
drop. Press the reset lever after pressure is restored.

6.14 — High Gas Pressure Switch
Adjust the scale setting to slightly above the normal burning pressure. The control circuit will be broken when
pressure exceeds the normal operating pressure. Unnecessary shutdowns may result if the setting is too close to
normal, however, regulations require that the setting may not be greater than 150% of rated pressure.
Manual resetting is necessary after a pressure rise. Press the reset lever after pressure falls.
