Upright Broiler/Salamander Protection
Upright broilers, chain broilers, and cheesemelters have specific coverage requirements. Unlike appliances with an
exposed flat cooking surface, these appliances have an internal cooking surface and only have a small opening in
the face or end of the appliance.
To cover internal hazards 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. This nozzle must
be branched off one of the nozzle drops and piped to the appliance opening. No more than 2 nozzles per drop.
The drawing below illustrates how this should be accomplished. Should the cooking surface of the appliance
exceed 1,050 in
2
, an additional nozzle will be required on the opposite of the appliance for added fire protection.
Refer to Figure 25 for details.
1. Pipe and fittings above the hood will be 1/2” copper pipe/Pro-Press, Grade L copper tubing and copper Pro-
Press 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. Install union in pipe leading to nozzle to allow for appliance removal and cleaning.
5. Nozzle heights above cooking surface (DIM A).
6. In addition to Standard Overlapping Protection, additional nozzles may be utilized for supplemental appliance
specific protection. No more than two (2) nozzles may be used on a single drop.
7. Appliance drop fittings may be sealed with pipe dope or Teflon tape.
