Atwood G6A-8 6-Gallon LP-Only DSI RV Water Heater

The Atwood G6A-8 is a 6-gallon LP-only DSI (direct spark ignition) RV water heater. The "G6A" identifies the 6-gallon Atwood gas water heater family; "8" reflects the BTU output class; LP-only configuration means no electric backup.

Specs: 6 gallons stored, 8,800 BTU propane burner, DSI (direct spark ignition — no standing pilot), 12V DC control. Aluminum tank. Recovery rate ~11 gph on propane.

LP-only configuration is the cost-saving choice for RVs without shore power AC needs for water heating. Common in: smaller RVs without 30A electrical capacity, boondock-focused use, budget-constrained replacements where $100 savings versus G6A-8E matters.

The DSI feature is the upgrade versus older Atwood standing-pilot units — automatic ignition, no manual lighting, more reliable cold-weather operation.

About $400 unit, $200-$350 installed. Parts widely available through Camping World.
