Two-stage ignition system controls (those with
N and Q suffix letters) can be converted using a
conversion kit (ordered separately). Order part No.
396021 to convert from natural (manufactured) to
LP gas; order part No. 396025 to convert from LP to
natural (manufactured) gas.
IMPORTANT: Ignition system controls with
step-opening regulators (SV9510P/ SV9520P) cannot
be field-converted to LP or natural gas. See
Table 3 for pressure settings for valves.
