701.12 Dampers Prohibited

Los Angeles Mechanical Code > 7 Combustion Air > 701.0 General > 701.12 Dampers Prohibited
JUMP TO FULL CODE CHAPTER
Combustion air ducts or plenums shall not be installed so as to require openings in or penetrations through construction where fire dampers are required. Manually operated dampers shall not be installed in combustion-air openings. With prior approval, power-actuated movable louvers admitting combustion air shall be permitted to be used and, where installed, shall be electrically interlocked with the main burner fuel-supply valve so as to prevent fuel delivery unless the louvers are in the fully open position.
