KC1000 Low NOx Conversion Kit, Part No. 124918-( ) is available in four configurations, designated -
1, -2, -3 and -4. The -1 and -2 Kits apply to newer KC1000 Water Heaters and Boilers respectively,
equipped with Siemens Safety Shutoff Valves (SSOVs) and C-More Control Systems. The -3 and -4
Kits apply to older KC1000 Water Heaters and Boilers respectively, equipped with Honeywell SSOVs.
Older KC1000 units may also be equipped with Modular or Digital Control Systems, instead of the C-
More Control Systems used on current KC1000 units. The “Kit Dash Number” column in the following
