Wood-fired pizza oven hood schedule
A wood-fired pizza oven is solid-fuel cooking — not a moderate-volume “Italian restaurant” on a semiannual sticker. Operators who keep the oven on the same quarterly contract as the rest of the line after the wood went in are usually on the wrong Table 12.4 row. This page is a facilities schedule for the wood oven path: monthly inspection floor, spark-arrestor filters, creosote in vertical runs, and what staff still owns between visits. Differentiate from the BBQ / smokehouse notes (long horizontals, continuous smoke hours) and from gas/electric char quarterly. Section numbers below are secondary summaries of NFPA 96 (2024). Verify the edition your AHJ adopted; this is not legal advice.
Short answer
Secondary sources citing NFPA 96 Table 12.4 name wood-fire pizza under solid-fuel cooking: plan monthly inspection for the exhaust that serves the oven. Cleaning triggers on grease/creosote depth (secondary §12.6.1.1), not the calendar alone — on a busy oven expect a full-system clean on most monthly visits. Use listed spark-arrestor filters (secondary §15.5), keep staff washing them on a short cadence, and do not leave the oven on a generic quarterly “restaurant” contract.
Which row is the wood oven on?
| Situation | Planning row | Notes |
|---|---|---|
| Wood-fired pizza oven (logs, chunks, or solid fuel) | Solid-fuel → monthly | Named Table 12.4 example (secondary) |
| Gas pizza deck / electric oven only | Volume-based (often moderate → semiannual) | Not the solid-fuel row — unless something else upgrades the system |
| Wood oven added under an existing shared hood | Treat that system as monthly | Highest-risk fuel on the path sets cadence |
| Charcoal / mesquite grill next to the oven | Still monthly solid-fuel | Same row — see also BBQ / solid-fuel guides |
Month-by-month operator schedule
| Cadence | Owner / staff | Vendor / inspector |
|---|---|---|
| Every month (≈ Day 1) | Confirm visit 1–2 weeks out; clear roof / after-hours access; pull last report for inaccessible notes | Table 12.4 solid-fuel inspection; measure / assess deposits; clean when thresholds crossed |
| Visit day | Keys, spark-arrestor pull if asked, photo of hood label before work | Full path: canopy, spark arrestors, plenum, vertical/horizontal duct, fan, containment; label + panel tags |
| Within ~2 weeks | File report + path photos; set next month due on wall calendar / binder | Written inspection (and cleaning, if done) report — secondary two-week window |
| Weekly (staff / equipment) | Secondary underwriter note: scrape combustion chamber to original surface weekly; wash spark arrestors before they restrict airflow | Not the hood vendor’s job unless contracted — ask who owns it |
| Between visits | Flashlight plenum check; note vertical-run odor / smoke spill; empty grease drip cups weekly (secondary §12.6.17) | Call-back if you escalate early creosote / heavy film |
| Quarterly calendar trap | If the rest of the kitchen is high-volume quarterly, the wood oven path still stays monthly — don’t “average” them | Separate sticker / schedule line for the solid-fuel hood if systems are split |
Spark arrestors, filter height, vertical creosote
- Spark arrestors — secondary §15.5: where airborne sparks/embers can be generated, spark arrester devices ahead of the grease removal device; filters constructed of steel/stainless or approved for solid fuel
- Filter height — secondary cite: filters a minimum of ~4 ft (1.2 m) above the appliance cooking surface
- Flush fit — no gaps that let embers bypass into the plenum / duct
- Staff wash cadence — spark arrestors load faster than standard baffles; many wood kitchens wash daily or several times per week
- Vertical runs — creosote sticks in risers and fan housings; canopy-only visits leave the fire fuel in place
- Separate exhaust — secondary field guides note solid-fuel paths are often required separate from the rest of the kitchen exhaust; confirm with your AHJ / design docs before you assume a shared duct is fine
What a good monthly wood-oven visit covers
- Contract line says solid-fuel / wood oven — not generic “restaurant”
- Spark-arrestor filters in scope; gaps and listing called out if wrong
- Plenum + vertical duct + fan cleaned when thresholds crossed
- Report names creosote / soot, not only grease film
- Path photos including a vertical opening or fan interior
What breaks the schedule
- Leaving the oven on a quarterly or semiannual kitchen-wide contract
- Standard baffle filters with no spark arrestor where embers are possible
- Canopy wipe while the riser stays tarred
- Staff never washing spark arrestors between pro visits
- Assuming the pizza deck’s “low grease” reputation cancels solid-fuel rules
Field note — don’t blur inspection and cleaning
- Table 12.4 is an inspection schedule. Cleaning is required when deposits cross secondary depth thresholds (~0.002 in on hoods/filters/fans/ducts per common secondary cites of §12.6.1.1)
- MSO underwriter secondary note: grease-infused creosote has a lower flash / auto-ignition profile than grease from gas/electric cooking alone — that is why solid fuel sits on the monthly row
- Facilitec secondary pattern: solid-fuel kitchens left on quarterly paper are a common fire-marshal deficiency — monthly is the floor
- Weekly combustion-chamber scrape (secondary underwriter note) is equipment-side work — it does not replace the exhaust-system monthly visit
Put this on the bid email
- Cooking type — wood-fired pizza oven; fuel (logs / chunks); hours per day; shared vs dedicated exhaust
- Cadence ask — monthly inspection with clean-when-due (expect clean most visits)
- Scope yes/no — spark-arrestor filters, plenum, vertical and horizontal duct via panels, fan, grease cup / containment
- Process — handles creosote in risers / bare-metal on accessible surfaces
- Proof — hood label, panel tags, report inside ~2 weeks, path photos including vertical or fan
Who it’s for / not for
- For: wood-oven pizza / Neapolitan / open-hearth facilities leads; multi-unit ops that added wood under an old restaurant contract; GMs rewriting the cleaner’s scope letter
- Not for: gas/electric deck-only schedules; BBQ long-horizontal smokehouse specifics (use the BBQ notes); inventing prices; replacing your AHJ’s adopted edition

Next step
Open the current hood contract. If the wood oven is still bundled under quarterly or “restaurant,” email the cleaner for a monthly solid-fuel line item with spark-arrestor scope, vertical-duct access, and path photos required every visit.
