    sheetrock...

    is classified as a combustible material...belive it or not....Some people are "alarmists" they like puffing them selves up by scaring people. Look at table 10.6.2 on nfpa31...it will show youa bunch of ways to reduce the clearances to combustibles by using sheetmeatal w/ an airspace. kpc

    bust open the UMC ,look at table 8-5 therein will be revealed the answer .... :)

    Table 3-3 figure 3-1 has a Picture that addresses the question so you don't have to waste time reading the code book :)) Mad Dog likes to refer to them as Knee pads Left by the previous installers :)

    to aid in the presentation of the idea to the home owner...bag off the terminology of calling the vent a Smoke Pipe:)

    NFPA

    NFPA is not NY State law. What is the regulation for a fire company that responds to a fire under the NFPA code? Is it two 18 year olds or three 18 year olds???? They don't mind telling everyone about fire so please tell me tell me NFPA. What makes up the manning for a fire Co. ?????

    I offered NFPA 211 as a source to answer the question of clearances. in most cases if a state does not go by a given organization such as NFPA or IRCC they still refer to it and in some cases exceed its recommendations.

    Do you have a reference that may be helpful in addressing this question? I’m always open minded and willing to learn.

    please clarify

    The clearances are based upon fuel types and materials. Please clarify what you have. By saying insulated into the utility room are you referring to an insulated factory chimney, an insulated listed liner inside a masonry chimney or L-vent? Once the chimney type is established, that will determine the clearance to that chimney.

    Next, the "smoke pipe" from the appliance to the chimney is determined by fuel type. For gas, it is a "vent connector", while oil is a "chimney connector.

    Unlisted single walled connectors are 6" for gas and 18" for oil unless listed otherwise. Factory chimney is 2" to combustibles. Before you hang the chimney inspector, I recommend you clarify what is what.

    FYI, while NFPA 211 may not have been voted into law in your area as a line item, it is still the code for most of the country for heating equipment. For gas appliances, both the Nat'l Fuel Gas Code NFPA 54 and the IFGC refer to 211 when discussing chimneys. Ditto for oil. Most all codes in the country refer to NFPA 31 for oil, which then refers you back to 211 for chimneys, connectors, and clearance reduction systems. NFPA 211 is THE National Standard. Whether a code or not, you should be aware of it because that is the measure to which you will be held in court.

    FYI, some of the other agencies that refer to 211 include ASHRAE, ASTM and UL. When UL tests something in a chimney, they use 211 as the reference for what kind of chimney to test into.

    Best to arm yourself with information before you bark.
