From: Patrick Regan
James Dayton Design,Ltd.
In our meeting on the Sth of October for the Minnetonka Center for the Arts,you brought up two
concerns regarding the Building Code.
The first question was if the Sculpture Room should be an H or I occupancy type instead of an E
occupancy. Upon reviewing Table 3-D of the UBC regarding Exempt amounts of Hazardous
Materials, I believe we fall within the exempt amounts. So I think we can remain Group E.
However, in Requirements for Group E Occupancies; Section 305.2.4 Special hazards states:
Laboratories,vocational shops and similar areas containing hazazdous materials shall
separated from each other and from other portions of the building by not less than a one-hour fire
resistive occupancy sepazation.
So here we will be providing a one hour occupancy separation along the North wall of the
Sculpture area. This will be a One-hour separation with a roll down fire-shutter for the door on
that wall. We will not be using that door for exiting so I believe it is ok to use a shutter there.
(See included sketch.)
The second concern was about the building separation between the new building and existing
building during construction. At the nearest location( see included site plan)the new building
will be 20'-5" from the existing building. According to Table 5-A UBC for Type II N
construction, we only need nonrated noncombustible walls and no requirement for openings. I
believe the existing building is Type II N as well, so it should have the same requirements.
Please let me know if the Orono Code has any special requirements for multiple buildings on one
site. If the existing building is Group E Type IIN construction we may be able to consider the

(g)Clearance.Such equipment shall be installed so as not to raise the tempera-
ture of surrounding combustible materia( more than 90°F. above ambient.
Small Ceramic Kilns
Sec. 1905. (a) General. The provisions of this section apply to kilns used for
ceramics that havc a ►naximum interior volume of 20 cubic feet and are used for
hobby or noncommercial purposes.
(b)Installation. Kilns shall be installed in accordance with the manufacturer's
instructions and the provisions of this code.
(c) Fuel-gas Controls. Fuel-gas controls shall comply with Sections 503 and
506. Standing pilots shall not be used with gas-fired kilns.
(cl) N;lectrical Equipment. All cicctrical eyuipment uscd as part of, or in
connection with, the installati��ns of a kiln shall comply with the requiretnents set
forth in the Electrical Code.
(e) Installations inside I3uilclinKs. In additi�m to othcr requirements specif�ied
in this section, interior installation shall meet the following rcyuirements:
l. Kiln clearances. "I'he�sides and tops of kilns shall he locatcd a minimun�of
18 inches from atiy noncombustible wall surface and 3 feet from any cornbustible
wall surface. Kilns shall be installed on noncombustible flooring consisting of at
least 2 inches of solid masonry or concrete extending at least 12 inches beyond the
base or supporting members of the kiln.
EXCEPTION: These clearances may be reduced, provided the kiln is installed
in accordance with its listing or to acceptable conclosions of testing reports submit-
ted to the building official.
ln no case shall the clearance on the gas or electrical control side of a kiln be
reduced to less than 30 inches.
2. Hoods. A canopy-type hood shall be installed directly above each kiln. The
face opening area of the hood shall be equal to or greater than the top horizontal
surface area of the kiin. 1'he hood shall be constructed of not less than 0.024-inch
(No. 24 U.S. gage)galvanized steet or equivalent and be supported at a height of
between 12 inches and 30 inches above the kiln by noncombustible supports.
EXCFPTION: E?tectric kilns installed with listed exhaust blowers may be used �
when marked as being suitable for the kiln and installed in accordance with manufac- �
..
turer's instructions. :?:
3. Gravity ventilation ducts. Each hood shall be connected to a gravity
ventilation duct extending in a vertical direction to outside the building.This duct
shall be of the same constructi<�n as the hood and shail have a minimum cr��ss-
sectional area of n��t less than one fifteenth of the face opening area of the hood.
The duct shall terminate a minimum of 12 inchcs above any portion of a building
within 4 feet and terrninate no less than 4 fcet from any openable windows or other
openings into the building or adjacent property line. The duct opening to the
outside shall be shielded, without reduction of duct area, to prevent entrance of
rain into the duct. The duct shall be supported at each section by noncombustible
supports.

4. Makeup air. Provisions shall be made for air to enter the room in which a
kiln is installed at a rate at least equal to the air being removed through the kiln
hood.
5.Hood and duct clearances.Every hood and duct serving a fuel-burning kiln
shall have a clearance from combustibie construction of at least l8 inches. This
clearance may be reduced in accordance with Table No. 5-B.
(�Exterior Installations. Kilns shall be installed with minimum clearances as
specified in Subsection (e) I of this section. Wherever a kiln is located under a
roofed area and is partially enclosed by more than two vertical wall surfaces, a
hood and gravity ventilation duct shall be installed to comply with Subsections(e)
2, (e)3 and(e)5 of this section.

Paul,
These are our current plans and elevations of the Art Center. You will see that the Cooling tower has been
removed from it's central location over the Elevators and has been moved to the North West end of the
building. This relocation was so that the enclosure around the unit would be under the 30'height
restriction.
I think you already have the most current Site plan. If you need another copy please let me,or Joe Favor at
Aslund and Assoc. know.If you have any other questions or comments please contact me.
