Rollout

Flame containment. Manual reset.

Walk 33 in Diagnose

8 plates — walk the one on the cabinet

First check

1 Treat this as flame outside the exchanger

Do not reset the Rheem R801S rollout and walk away. Write the code, kill the call, and look for flame at the burners, crossover, and vestibule before you do anything else.

Expect: No flame outside the exchanger. Burners seated. Crossover lit.

If pass: Still inspect secondary / flue / condensate before you reset.

The rest of the walkthrough is Diagnose.
