Atwood GC6A6 Combination Gas/Electric Water Heater Parts Guide
The GC6A6 parts guide covers both the propane pilot heater and its electric heating system. It is presented in two sections so the gas-side thermostat and electric thermostat are not confused during parts identification.

Reference guide: The original model-specific drawing numbers are shown below. Linked part numbers lead to a NewRVParts product with the same Atwood manufacturer number. Historical and superseded numbers are deliberately left unlinked; a product link does not establish fitment, availability, or compatibility with all revisions.
