Appliance with Upright Obstruction
Salamanders/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), is placed at the opening and aimed at the opposite rear corner of the appliance. The nozzle may be
branched off one of the nozzle drops with a tee or have a dedicated nozzle drop and piped to the appliance open-
ing. No more than two nozzles can be utilized for a single drop. Should the cooking surface of the appliance
exceed 1050 in
2
, an additional nozzle will be required on the opposite side of the appliance for added fire protec-
tion, refer to Figure 29. Salamander/Cheesemelters should follow “Upright Broiler/Salamander Protection” on
page 24.
Additional nozzles may be piped from nozzle drops nearest the appliance, or have a dedicated nozzle drop to
cover the hazard underneath the salamander. The nozzles are aimed at the centerline of the cooking surface, a
minimum of 35”-50” away (DIM A). Overlapping coverage is required for appliance specific coverage.
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. Install union in pipe leading to nozzle to allow for appliance removal and cleaning.
5. 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.
6. Appliance drop fittings may be sealed with pipe dope or Teflon tape.
7. Shelf/obstruction that extends more than 10-12” from the rear edge of the cooking hazard to the front edge of
shelf/obstruction.
8. The spacing between nozzles will be either 36” or 30” maximum, based on the overlapping protection required
for the appliance hazard below the obstruction.
