1- NX1020 gas pressure sensor used. The unit Monitors
the gas pressure (including gas pressure limits) if gas pro-
file is selected but does not perform gas valve proving.
2- NX1020 gas pressure sensor used. The unit monitors
the gas pressure (including gas pressure limits) and per-
forms Gas Valve Proving if a gas profile is selected.
