Standards and AHJ note

This calculator is a planning aid, not the NFPA 96 standard.
Verify current NFPA 96 requirements, local AHJ expectations, customer contracts, and insurer rules before relying on an interval.
If observed grease accumulation is heavier than expected, recommend a shorter interval and document the reason.

Record the calculated next service date in the customer report.
Keep before/after photos tied to the system cleaned on this interval.
List grease-load observations that support the next cleaning recommendation.
Note any customer, insurer, contract, or AHJ rule that overrides the default interval.

Use the interval as a documented recommendation.

The calculator helps crews and office staff explain why a next service date was recommended. Add the date to the service report, then support it with photos, grease-load notes, deficiencies, and any stricter customer requirements.

Capture visible grease-load evidence before cleaning starts.
Document whether the operation uses solid fuel, charbroiling, wok cooking, or long hours.
Record customer, insurer, contract, or AHJ rules that shorten the interval.
Keep the next service date visible in the customer handoff.

What this calculator does not replace

This free calculator is a documentation and planning aid. It is not the NFPA 96 standard, does not certify an interval, and does not guarantee acceptance by an AHJ, insurer, customer, or fire marshal.

Verify the current standard, local authority expectations, customer contract requirements, and observed system condition before relying on any interval.
