  • Equipment and Caulking Installation Instructions Using Caulking Applicator Guns Photo 1A
    Equipment and Caulking Installation Instructions Using Caulking Applicator Guns Photo 1a There are different types of caulking applicator guns available. The recommended procedure when using the different styles will be described in Sections A, B and C. Section D will then describe the recommended procedures to follow to install the caulk and finish the job. Section A Applying Caulk in Plastic and Cardboard Fiber Foil Wrapped Cartridges Photo 2a There are a variety of applicator caulking guns available to do firestopping. We recommend using a smooth rod style rather than the less expensive ratchet rod type. When dispensing caulk from a 29 ounce-size cartridge, we recommend using the rod tape gun with at least a 12:1 thrust ratio. The higher thrust ratio means less hand fatigue since the firestopping caulks are usually high viscous materials. It will also help when the product becomes stiffer in the colder temperatures. (12:1 ratio generates approximately 300 pound thrust) Photo 3a For manual single component cartridge applicator guns. Select the correct size manual drive frame-style cartridge gun for either the 10-ounce (300ml) or the larger 29-ounce (850 ml) plastic or cardboard fiber foil wrapped tube type. (see photo #1a) Using a utility knife cut off the end of the plastic tip/nozzle of the sealant tube to the desired opening size. The cut can be straight across (90º) or angled Photo 4a (45º). Cutting too small of an opening will restrict the flow of material and a smaller bead size than needed may result. The smaller opening will also require more triggering action (pressure) to move the material out of the tube.(see photo #2a) Using a screwdriver or other pointed utensil insert it into the plastic nozzle to puncture the membrane and allow the caulk material to flow.

    New York State Department of Taxation and Finance Office of Tax Policy Analysis TSB-A-07(1)S Sales Tax Technical Services Division February 8, 2007 STATE OF NEW YORK COMMISSIONER OF TAXATION AND FINANCE ADVISORY OPINION PETITION NO. S040628D On June 28, 2004, the Department of Taxation and Finance received a Petition for Advisory Opinion from Countryside Stove and Chimney of Burnt Hills, 839 Saratoga Road, Burnt Hills, New York 12027. The issues raised by Petitioner, Countryside Stove and Chimney of Burnt Hills, are: 1. Whether installations of various wood, pellet, and gas burning heating appliances qualify as capital improvements to real property for New York State and local sales and use tax purposes. 2. Whether the installation of manufactured stone veneers on an interior or exterior wall qualifies as a capital improvement to real property for New York State and local sales and use tax purposes. Petitioner submits the following facts as the basis for this Advisory Opinion. Petitioner is a retail store selling and installing gas, wood, and pellet burning stoves that are placed on the floor on noncombustible material either purchased or provided by the customer. The gas stoves can be either directly vented from the stove out the side of the building using a wall thimble and a cap on the outside of the building or vented into the customer’s existing chimney by installing a stainless steel flexible liner in the chimney with its own rain cap. The wood and pellet burning stoves are also vented straight out the back of the stove and through a wall or chimney.
