fireplace areas should have no floor grating or plate and should
be free of any structural members. Acceptable tolerance should
be plus or minus 6.4 mm maximum. Provisions for supporting the
future device are shown in Appendix A, Figures A-9A and A-9B.
Provide a temporary bolted post and chain railing around the
opening for safety until the device is installed.

Device. (For information only and does not pertain to
the device contract.) The device equipment provided in the
trainers consist of the following:
a) Fireplaces should be computer-controlled propane
burners hidden in a mockup which is designed to represent the
item burning. See Appendix A, Figures A-1, A-2, and A-3. Most
fireplaces will be floor-mounted and fed from the crawl space.
Fireplaces which are not fed from the crawl spaces, such as:
electrical panel, wire bundle, and vent duct fires, should
include propane equipment in their electrical cabinets. Each of
these cabinets will contain a propane sniffer which will detect
any propane which has leaked into the cabinet. There will also
be propane sensors on both sides of the wall underneath
electrical cabinets containing burners. When activated, this
sniffer will shut down its fireplace until the propane is
removed from the area.
b) Design device equipment to go through a 914 mm
personnel door unless other provisions are made.
c) The artificial smoke generator (provided by the
device contractor) is started at the beginning of a training
session and runs continuously. Air at 538 degrees C should be
discharged from bypass ducts which keep the system at operating
