Suburban 4 Gallon DSI Water Heater Prep

Use the Suburban 4 gallon Advantage DSI water-heater page to capture tank size, switch, light, winterization, and service details.

Owner-safe checklist

• Record the 4 gallon Advantage DSI water-heater model, switch or light behavior, tank-size context, winterization state, LP odor state, and symptom timing.
• Save photos of the model label, switch or light, visible exterior condition from normal owner access, and service paperwork.
• Turn the water heater off and turn LP off for LP odor, overheating, leak, exhaust concern, or repeated ignition trouble.
• Use Suburban support, dealer, or qualified RV water-heater service for LP system, installed power, internal parts, warranty, or repair decisions.
