DATE March 22, 1994
SUBJECT:
Request approval for changes in Chapter 32, Mechanical Code, of the
Municipal Code regarding Gas Venting Systems.
BACKGROUND:
Chapter 32 of the Ames Municipal Code has adopted the 1991 Uniform
Mechanical Code, however because of rapidly changing technology in
mechanical systems, the Mechanical Board of Appeals would like to have the
following paragraph of Sec. 901 of the Mechanical Code which now reads:
"Gas venting systems serving appliances equipped with draft hoods and
appliances listed for use with Type B vents may be designed in
accordance with tables in Appendix C, Chapter 9, when the design
method has been approved by the building official."
to be changed to read as follows:
"Gas venting systems serving appliances equipped with draft hoods and
appliances listed for use with Type B vents may be designed in
accordance with the Gas Appliance Manufacturer's Assn. Venting Tables
supplied by the manufacturer of the appliance or with Tables in
Appendix C, Chapter 9, when the design method has been approved by
the Building Official or Mechanical Inspector."
The attached ordinance was prepared with the change and some renumbering
also occurred to clean up the Mechanical Code.
The mechanical contractors in Ames asked the Mechanical Board of Appeals to
change the code concerning the venting tables. It will allow greater
flexibility in the installation of mechanical venting systems for furnaces and
water heaters. The venting tables that come with the manufacturers
instructions allow alternative methods for achieving the end goal, which is to
vent the gases and eliminate carbon monoxide buildup in the buildings. The
mechanical board voted unanimously for this change. They received
additional support from the Plumbing Board of Appeals and the Building
Board of Appeals. The Board held a public hearing on this change on
February 21, 1994 and found no opposition.
ALTERNATIVES:
1 . Approve changes as submitted for your consideration.
2. Deny the request.
MANAGER'S RECOMMENDED ACTION:
It is recommended by the City Manager that the City Council adopt
Alternative #1 granting the submitted changes.
