Enjoy long, hot showers on the road with minimal maintenance — the aluminum tank eliminates the need for an anode rod.

⭐ Rapid Heating — 10,000 BTU Electronic Ignition

Standout heat performance vs older-generation water heaters: 10,000 BTU electronic ignition burner delivers exceptional heat output. Meaningful benefits:

• Long, hot showers on the road — robust burner system efficiently produces hot water for extended periods
• Consistent hot water supply for your RV
• Electronic ignition — no manual pilot lighting required

⭐ Aluminum Tank — No Anode Rod Required

Standout maintenance benefit vs steel-tank water heaters: lightweight aluminum tank is corrosion-resistant and does NOT require an anode rod. Meaningful benefits:

• No annual anode rod replacement — a common Suburban maintenance requirement is eliminated entirely
• Corrosion resistance — extended product life
• Lightweight construction — easier handling and installation
• Low overall maintenance

⭐ Easy Flange Installation + Attractive Vent Design

• Flange-mount design — simplifies installation with quick and easy setup
• Aesthetically designed vent — improves airflow performance and appearance

⚠️ Access Door Sold Separately — Required for Complete System

Important: The exterior access door is NOT included with this water heater. You MUST purchase both the water heater AND a compatible door for a complete, functional installation.

⚠️ Replacing a Legacy Atwood 6-Gallon Heater? Door Conversion Kit Required

The Dometic WH-6GA is physically smaller than the older Atwood (Legacy) 6-gallon model it replaces. If you're replacing an Atwood unit, you'll need one of these conversion kits to properly cover the original rough opening hole:

• #94946 — White Door Conversion Kit (6 Gal)
• #94951 — Black Door Conversion Kit (6 Gal)

Gas + Electric Alternative

Need both LP gas AND 110V electric heating modes for shore-power operation? See the Dometic WH-6GEA (#94002) — the same 6-gallon Dometic platform with an added 110V electric heating element. The WH-6GEA is also a direct replacement for the Suburban SW6DE gas/electric water heater.
