There are only three actions a TC can take at the First Draft (ROP)

meeting: 1. Resolve a Public Input (no change to the document) 2. Create a First Revision (change to the document) 3. Create Committee Input

Resolve Public Input (no change to the document)

TC must provide a response (Committee Statement/CS) to ALL Public Input (proposal).

CS for not doing what is suggested

Sample Motion: “I make a motion to resolve PI#_ with the following committee statement__.” Approval by meeting vote (simple majority). Not subject to Ballot.

Create a First Revision (change to the document)

TC must create a First Revision (FR) for each change they wish to make to the document, either using Public Input for the basis of the change or not using a Public Input for the basis. One or more Public Input can be considered for the FR.

All Public Input requires a response

TC can use a Public Input for basis i. Sample Motion: “I make a motion to revise section __ using PI#_ as the

basis for change.” Approval by meeting vote (simple majority) and final approval through ballot.

TC develops revision without a Public Input for basis i. Sample Motion: “I make a motion to revise section __ as follows___.”

Approval by meeting vote (simple majority) and final approval through ballot.

First Revisions require a committee statement

Committee Input

TC may create a Committee Input (CI). This replaces the old system “rejected” Committee Proposals. CIs will get printed in the report but will not be balloted or shown as a change in the draft. CIs are used to solicit public comments and/or as a placeholder for the comment stage.

i. Sample Motion: “I make a motion to create a CI with a proposed revision to section__ as follows___.” Approval by meeting vote (simple majority). Not subject to ballot.

3.3.100.1 Combustible Material.

Material made of or surfaced with wood, compressed paper, plant fibers, plastics, or other material that canignite and burn, whether flameproofed or not, or whether plastered or unplastered A material that, in theform in which it is used and under the conditions anticipated, will ignite and burn; a material that does notmeet the definition of noncombustible or limited-combustible .


The existing definition in NFPA 211 is not appropriate. It discusses whether some specific combustible components are present or not and it also contains a deprecated term "flameproofed" which is not representative of the action of adding fire retardants to a material. Even more important, this definition should be replaced by one that is in wider use, recognizing the need for uniformity of definitions within NFPA. The proposed definition is that from NFPA 1, fire code, and is used in several other documents as well.

3.3.100.2 Noncombustible Material.

A material that, in the form in which it is used and under the conditions anticipated, will not ignite, burn,support combustion, or release flammable vapors, when subjected to fire or heat; materials that arereported as passing ASTM E136, Standard Test Method for Behavior of Materials in a Vertical TubeFurnace at 750°C , shall be considered noncombustible materials. (see 4.1)


The tendency in NFPA documents has been to describe a noncombustible material as a function of the requirements needed to meet that criterion and such requirements need to be in the body of the standard as opposed to being in the section on definitions, which are not enforceable. NFPA 101, NFPA 5000 and most other NFPA documents have done this by simply referencing the appropriate section in the document and placing the requirements in that section. The simple statement that a material is "not capable of supporting combustion" begs the question as to how this is determined. In the US this has been determined for many years by using ASTM E136 and, in recent years, by using ASTM E2652 as an alternate. This public input and the associated one for the new section 4.1 use the language extracted from NFPA 5000 (and NFPA 211 already extracts language from NFPA 5000 elsewhere).

The first proposed change here is to divide the current Chapter 11 Fireplaces into two chapters: Chapter 11Factory-Built Fireplaces and Chapter 12 Masonry Fireplaces. This will not only make the distinctions between the requirements for these two types of fireplace clearer and less likely to misinterpretation, this organizational change will be consistent with the treatment of chimney types in the Standard (Chapter 6 Factory-Built Chimneys and Chimney Units; Chapter 7 Masonry Chimneys; and Chapter 8 Unlisted Metal Chimneys for Nonresidential Applications). This rearrangement also addresses (and improves) part of the purpose originally proposed earlier this year regarding the separation of accessories for masonry and factory-built fireplaces.

Additional proposed revisions:Re-numbering of Chapters and Sections (will also call for re-numbering of subsequent chapters if adopted).

Move and re-number current 11.2 Masonry Fireplaces and current 11.3 Hearth Extensions in their entirety to a new Chapter 12 Masonry Fireplaces for clearer distinctions and increased clarity regarding requirements for the two types of fireplaces.


38 of 53 1/17/2017 1:16 PM


Page 58 of 82

Move and re-number all of 11.4 Combustion Air Ducts EXCEPT 11.4.1.1 to new Chapter 12 for clearer distinctions and increased clarity regarding requirements for the two types of fireplaces.

Retain and re-number 11.4.1.1 as 11.5 Combustion Air Ducts for clearer distinctions and increased clarity regarding requirements for the two types of fireplaces.

Delete “the specific” and change “fireplace” to “fireplaces” as part of the distinction between accessories and chimneys being suggested in Public Comments 77 (3.3.2), 80 (14.7.1.1 and 2) and 81 (A.3.2.2). To my knowledge, accessories (as defined in my proposals) are not tested and listed for use with specific fireplaces. Components, which are part of testing and listing are covered in the revision in the Maintenance chapter (14.7.1)

The first proposed change here is to divide the current Chapter 11 Fireplaces into two chapters: Chapter 11 Factory-Built Fireplaces and Chapter 12 Masonry Fireplaces. This will not only make the distinctions between the requirements for these two types of fireplace clearer and less likely to misinterpretation, this organizational change will be consistent with the treatment of chimney types in the Standard (Chapter 6 Factory-Built Chimneys and Chimney Units; Chapter 7 Masonry Chimneys; and Chapter 8 Unlisted Metal Chimneys for Nonresidential Applications). This rearrangement also addresses (and improves) part of the purpose originally proposed earlier this year regarding the separation of accessories for masonry and factory-built fireplaces.

Additional proposed revisions:Re-numbering of Chapters and Sections (will also call for re-numbering of subsequent chapters if adopted).

Move and re-number current 11.2 Masonry Fireplaces and current 11.3 Hearth Extensions in their entirety to a new Chapter 12 Masonry Fireplaces for clearer distinctions and increased clarity regarding requirements for the two types of fireplaces.

Move and re-number all of 11.4 Combustion Air Ducts EXCEPT 11.4.1.1 to new Chapter 12 for clearer distinctions and increased clarity regarding requirements for the two types of fireplaces.

Retain and re-number 11.4.1.1 as 11.5 Combustion Air Ducts for clearer distinctions and increased clarity regarding requirements for the two types of fireplaces.

Delete “the specific” and change “fireplace” to “fireplaces” as part of the distinction between accessories and chimneys being suggested in Public Comments 77 (3.3.2), 80 (14.7.1.1 and 2) and 81 (A.3.2.2). To my knowledge, accessories (as defined in my proposals) are not tested and listed for use with specific fireplaces. Components, which are part of testing and listing are covered in the revision in the Maintenance chapter (14.7.1)

13.2.3

Solid fuel–burning appliances shall not may only be installed in any location where gasoline or any otherlocations where flammable liquids, vapors or gases are stored properly and fully in accordance with NFPA30. For the purposes of this section, examples of flammable vapors or gases include (but are not limitedto) gasoline, propane, kerosene, alcohol, acetone, butane, naphthalene, acetylene, hydrogen, oroxygen. Examples of flammable liquids include hydrocarbon-based oil or grease, cooking oil, linseed oil,liquified candle (tallow) wax, cologne and perfume. If any of these substances are present in a locationwhere a solid fuel-burning appliance is installed, they must be self-contained with airtight seal to preventleakage, and must also posess appropriate and legal labelling as to their contents . This includes anymedical gases required for life-sustaining treatments. For example, medically required oxygen tanksdesigned for home use must be appropriately labelled and stored, and extreme caution exercised at alltimes.


Hello, thank you for allowing my suggestions. The reason that I suggested some improvement in the wording is because the previous wording of the section seemed to omitted several dangerous compounds known to be volatile which are commonly in the same location where solid-fuel heating appliances are installed. The section wording also had no focus on risk mitigation and protective measures that can enable a safely shared location for the appliance and also the flammable compounds. I suggested keeping the word "location", though it is imprecise and may be too broadly construed when considering the overall safety of modern solid-fuel appliances. For example, a "location" could mean a particular room in a house, or it could mean the address of the house itself, or it could mean on the same wall as a shelf or cabinet containing flammable liquids. Safely installed, energy code compliant solid-fuel appliances can safely co-exist in the same household with citizens who require supplemental oxygen for medical diagnoses, and can safely be installed in homes even while there are containers of flammable cleaning solutions and alcohol beverages (i.e, hard liquors including highly flammable straight grain alcohol. Thank you for considering my suggestions to highlight safety and risk mitigation and to make the NFPA concerns more precise.

13.2.4

Solid fuel–burning appliances shall not be installed in any garage

(I recommend we delete this section) Flammable vapors and liquids are handled in previoussection. The word "garage" has many meanings and is used in the vernacular by many peoplefrom different cultural backgrounds to mean different things. Some people interchange "barn" for"garage" or "shed" or "workshop" or "guest house". Rather than writing a lengthy treatment of theformalized definition of "Garage" (which may take a room full of college professors a week or moreto figure out), perhaps it's best to focus on the reason why we don't want solid-fuel heatingappliances in certain kinds of locations. And if they are going to be installed in certain higher-risklocations, to build in safety and protective factors to enable risk reduction and overall safety .


I suggested we delete this section because it may be somewhat redundant with the previous section. While we all know and agree the broadly stated sentiment expressed by this section, it may be too far reaching and is not as focused on the details. Plus using the word "garage" is too easily circumnavigated by persons who are not safety minded. Instead of getting a permit to build a garage, they will get a permit and list the structure as a "sub-house playroom" or simply "outbuilding". As language continues to evolve across generations, it might be better to address the long-standing and always present fire risks, and to keep thinking forward more and more about prevention.

Chimneys designated as Type HT are listed for venting flue products not exceeding 1000°F (538°C)continuous. In addition, they comply with the 10-minute 2100°F (1149°C) temperature test requirements ofANSI/UL 103, Standard for Factory-Built Chimneys for Residential Type and Building Heating Appliances.Such test requirements were developed to simulate the effects of a chimney fire. Type HT chimneys arerequired on certain controlled-combustion solid fuel–burning appliances because such appliances are oftenassociated with a higher likelihood of creosote buildup and associated occurrence of chimney fires.
