Suburban SW water-heater model-suffix service prep

Use this when a Suburban SW water-heater model suffix, capacity, or control option must be documented before support.

Owner-safe checklist

• Record SW model suffix, capacity, control option, installed location, visible labels, power source selected, and exact hot-water symptom.
• Use the Suburban sheet only to decode model-family and control-option names from owner-visible labels.
• Shut the water heater down for odor, leak, overheating, repeated failure, or control behavior that does not feel normal.
• Use Suburban support or qualified RV water-heater service for model suffix questions, parts selection, or symptoms beyond normal controls.
