Pizza Ovens
Pizza ovens have specific coverage requirements, unlike appliances with an exposed flat cooking surface,
these appliances have an internal cooking area and only have a small opening in the face or end of the
appliance. When installing the appliance, make sure the nozzle does not obstruct cooking operations.
To cover the internal hazard posed by these appliances, an Overlapping Female (OL-F) nozzle (previously
3070-3/8H-10-SS) must be placed at the opening and aimed at the opposite rear corner of the appliance.
No more than two nozzles can be utilized for a single drop. Refer to Figure 31 for single stack ovens.
Figure 32 and Figure 33 on page 31 show dual and three stack oven installation examples. Should the
cooking area of the appliance exceed 1200 in
2
, an additional nozzle will be required on the opposite side of
the appliance for added fire protection. Each nozzle can cover 1200 in
2
.
All dimensions fixed unless otherwise noted (e.g., min/max).
1. Pipe and fittings above the hood will be 1/2” copper pipe/Pro-Press, Grade L copper tubing/fittings.
2. Pipe and fittings inside the hood capture volume will be 3/8” NPT stainless steel or chrome-plated
black iron. No sleeving permitted.
3. Appliance coverage piping that is field piped - unions, elbows, and nozzles factory provided.
4. No more than two (2) nozzles may be used on a single drop.
5. Appliance drop fittings may be sealed with pipe dope or Teflon tape.
