 SUMMARY OF IMPLEMENTED  MODIFICATIONS  
The following is a summary of the amendments proposed with 15- day language. It does 
not include non- substantive amendments to correct typographical or grammatical errors, 
change/correct numbering or formatting, or improve clarity.  
 Section 1602:  
 
- Added “including embedded fans sold for replacement of another embedded fan”  
to excluded item (G) from the definition for Commercial and Industrial Fans and Blowers. The change was implemented to clarify that all embedded fans , 
including those sold for the sole purpose to replace an existing embedded fan, are excluded from the definition for Commercial and Industrial Fans and Blowers (CIFB) and will n ot need to comply with the proposed regulation. However, if the 
same fan model is sold as a CIFB, the fan model number is subject to the 
proposed regulations.  
- Included new exclusion it em (K) to the definition for CIFB. The exclusion reads “a 
fan that is designed and marketed to operate at or above 482 degrees Fahrenheit (250 degrees Celsius) .” The exclusion was  listed under the safety 
fans definition, but after further review it was appropriate to move the exclusion since it was not a characteristic of a safety fan.  
- Removed the definition for “Dual use fan” since the term is no longer being used under the proposed regulation.  
- Added the “total and static” language to the “Maximum pressure” definition. The change was implemented to clearly communicate that the maximum pressure can be of the total or static nature as both can be used and are dependent to the 
fan it was tested, and the type of pressure used during the test.  
- Deleted the first item from the safety fan definition. The change was necessary since the fans that operate at or above 482 degrees Fahrenheit (250 degrees Celsius) are now listed as an exclusio n to the proposed definition for CIFB.  
- Moved Item 2 to Item 1 in the safety fan definition and included the determiner 
“an” into the item. The changes were necessary since item 1 was removed from 
the proposed definition and the determiner “an” is necessar y.  
- Moved item 3 to item 2 in the safety fan definition and deleted the conjunction “or” at the end of the item. The changes were necessary since item 1 was deleted and because the conjunction was no longer needed.  
- Moved item 4 to item 3  in the safety fan definition and added the conjunction “or” 
at end of the item. The changes were necessary since item 1 was deleted from the proposed definition and the conjunction was needed since it is the penultimate item . 
- Added item 4 to the proposed definition for saf ety fans  to include power ventilator 
for smoke control systems that comply with ANSI/UL 705 Power Ventilators (dated August 23, 2021) .  
- Added reference t o ANSI/UL 705 to the list of referenced material at the end of 
the section. The added reference item is  necessary since it is used under item 4 
of the safety fans definition .  
Section 1606:  
- Effective date was updated in Table X to reflect  the anticipated adoption date.  
- Table X was edited  to remove the motor model number and include instead the 
type of motor in the fan being sold. The permissible answer will be:  
o None, Single- phase induction, Polyphase induction, Synchronous DC 
(including ECM),  Permanent magnet AC, or Other.  
This c hange was necessary to address a comment  received during the comment 
period,  which indicat ed that the original proposal would generate large amount s 
of data due to the endless combinations of motor model numbers that different 
manufacturers use for the same type o f motor. The change was made to capture 
the type of motor in the fan and avoid the unnecessary data that would be 
generat ed by pursuing the different model numbers that fans are sold with.  
- Table X was edited to include the motor  nameplate horsepower  if fan is sold with 
an induction motor.  The change was necessary to capture necessary data that 
will help future enforcement of the proposed regulation.   - The “pressure type” field was added to Table X. This field is necessary for future 
verification of the certification of the commercial or industrial fan or blower . 
- Table X was edited to remove the controller model number if a fan is sold with a controller and instead require the type of controller  with the following permissible 
answer s:  
o None, Variable, or Other  
The changes were necessary to address the problems identified by stakeholder 
regarding the “ controller model number ” previously required.  
- Edited the type of units for the airflow data points needed for certification to 
reflect CFM rather than SCFM since AMCA’s test procedure does not correct for SCFM but rather  it converts pressure to standard air density  and reports the 
airflow in CFM . 
- Added reference to AMCA 214- 21 to the “Method used to determine the FEP
act of 
test method in section 1604(d)(2) ” field of table X. The change was needed to 
add clarity  to the origin of the sections used to calculate the FEP act of the 
proposed test procedure.  
Section 1607  
- Effective date was added to subsection 1607(d)(16) to reflect the anticipated adoption date.  
- Added the type of pressure,  either static or total , to the labeling requirements  
provided in subsection 1607(d)(160(A) . The change was required to require that 
the label clearly communicates the type of pressure.  
Additional Documents incorporated by reference during all comment periods:  
- ANSI/U L 705 Power Vent ilator (August 2 3, 2021)  
- ISO 80079 -26:2016, Explosive atmospheres –  Part 36: Non- electrical equipment 
for explosive atmospheres - Basic method and requirements  
SUMMARY AND RATIONAL OF SUGGESTED  MODIFICATIONS  NOT 
IMPLEMENTED   
AHRI and AMCA suggested to include “except replacement embedded fans ” to sections 
1606 and 1607. Staff rejected this change because embedded fans have been added to 
items (G) excluded from the proposed definition of commercial and industrial fans and 
blowers ( exception G), and therefore all  embedded fans sold exclusively for 
replacement of another embedded fan are exempted from the regulations.  Therefore, it 
is no longer necessary to include in the exclusion in sections 1606 and 1607 .  CA IOUs  requested changes to include the voltage and the rated nameplate 
horsepower for polyphase motors. Since the motor model number has become a 
data issue, and because the type of electric driver (motor) can be used to check the right procedure of the test procedure was used for certification, the suggested change was not implemented.   
CA IOUs, AMCA, and Greenheck suggested to change the motor and controller 
model number sold with the unit to be changed to those used for certification. Since the field will be changed to reflect the type of motor and controller rather 
than the model number for both, the comments were not implemented.  
CA IOUs recommended includ ing the conversion factor for pressure and FEI
act in 
standard air density units  within Table X . CEC will clarify the type of units 
required for these fields in the instructions for completing certification filing – the 
determination of these values is already explained in greater detail in the test 
specifications, and including this statement  within this tabl e could lead to 
confusion.   
AMCA submitted comments recommending  excluding  custom fans, those are 
fans that are not listed by manufacturers in their catalogs and are built following special requirements and measures. Since the fans do not need to be certified until the point of sale, the suggested comment was not implemented,  and this 
was clarified to manufacturer.   
Greenheck suggested harmoniz ing the proposed regulations  with the requirements of 
Tile 24 and the tolerances for AMCA Certified Rating Program (CRP).  After clarification , 
it was understood that the harmonization being referred to was regarding the submittal 
of data into MAEDbS and AMCA CRP. Since AMCA can become a third -party certifier,  
and since  the proposed regulation utilizes the same data utilized by AMCA, the 
proposed regulation is harmonized, to the extent that i t can be, with AMCA’s CRP and 
Title 24 requirements.
