Range With Upright Obstruction - CaptiveAire EWC Installation, Operation And Maintenance Manual

Range with Upright Obstruction

Salamander/Cheesemelters that are mounted over range(s) require dedicated coverage. Coverage for
range w/upright obstruction is 18" wide by 26" long (deep) per nozzle. The R nozzle must be positioned at
the left to right edge and centered on the depth of the protected area. One R nozzle can provide protection
for ranges 18 inches wide by 26 inches deep. Two R nozzles can provide protection for a range 36 inches
wide by 26 inches deep. Additional nozzle(s) must be used for ranges exceeding 18" in width, provided no
single nozzle coverage exceeds 18" max-width. Refer to Figure 33 for an example of modular coverage
using two nozzles. Salamander/Cheesemelters should follow appliance coverage for "Upright Broiler/
Salamander Protection" on page 28.
All dimensions fixed unless otherwise noted (e.g., min/max).
NOTE: Appliance Drop Fittings Must Not be Sealed with Pipe Dope or Teflon Tape.

When protecting ranges in accordance with these low proximity recommendations, the following minimum
pipe requirements must be met to prevent splash:
• Minimum of 16' of pipe, 1 tee & 4 elbows prior to the first R nozzle protecting a low-proximity range.
• Minimum 6.5' of pipe after the tee.
• Minimum of 6 flows in the system.
