These direct ignition combination gas controls are used
in gas-fired appliances with capacities up to 300 feet
at 1 inch wc pressure drop [8.5 meters
for natural gas. They include a manual valve, two automatic
operators, a pressure regulator, and a conduit cover. See
Table 1 for temperature ranges and regulator types.
