FOREWORD This technical guide was prepared in response to increasing concerns over the requirements for through-penetration firestopping as mandated by codes, specified by system designers, and required by code officials and/or other authorities having jurisdiction. The language in the model codes, the definitions used, and the expectations of local code authorities varies widely among the model codes and has caused confusion in the building construction industry. Contractors are often forced to bear the brunt of inadequate or confusing specifications, misunderstandings of code requirements, and lack of adequate plan review prior to construction. This guide contains descriptions, illustrations, definitions, recommendations on industry practices, designations of responsibility, references to other documents and guidance on plan and specification requirements. It is intended to be a generic educational tool for use by all parties to the construction process. Firestopping Guideline • Second Edition iii FIRE AND SMOKE CONTROL COMMITTEE Phillip E.

  • Installation Guide
    Installation Preparation of the hood for installation: To facilitate the installation it is recommended to remove the panel before installing the hood. Attention! Keep both hands on the panel when disassembling or reassembling it into place to prevent it from falling and causing damage to persons or property. Disassembly: - Pull the panel (FRONT SIDE) firmly down, - Push the small lever, located in the right side of the panel, to the left, - Unhook it from the rear joints. 8 Installation - Ducting version 1. Pre-installation calculations 2. Preparation of mounting surface K = Kitchen Height Installing supports above ceiling drywall. C = Counter Height (36" standard) P = Prefered Height of Hood Bottom above counter (Recommended 24”-30”) H = Hood height your installation H = K – C – P a) Select a hood preference height P that is comfortable for the user. (from 24” to 30“). b) Calculate Hood height your installation H = K-C-P. c) Confirm that H is within the range of min to max H found for your model (See “Dimensions and clearances” paragraph). If not adjust your installation. Note: Take into consideration the hood depth; the hood could be much deeper than the cooktop. a. Mark center lines of cooktop or range on ceiling above. Use centerlines marked on ceiling to position the mounting template. Note location of hood front (that indicated with a printed arrow), side, and mounting holes indicated on template. Note: Remember that printed arrow on template corresponds to front of the hood and consequently to side where control panels will be located at the end of installation) b.

  • Electrical Conduits
    Electric Level 5 Electrical Conduits What’s it all About? Electrical conduits refer to an electrical system used to protect and provide route of electrical wiring. Electrical conduits are made of metal, plastic, or fiber and could be rigid or flexible. Conduits must be installed by following standard regulations, as those provided by the manufacturer and the National Electrical Code (NEC). Keys to Remember • The 2017 NEC covers 12 types of conduits. Articles 342 through 362 specify use, installation, and construction specifications. • Fill rates, or how many wires can be put in the conduit, is covered in the 2017 NEC Annex C. • Sizing - Conduit tubing uses Outside Dimensions (OD); conduit piping uses Nominal Pipe Size (NPS). Sizes range from 3/8” to 6”. • With any wiring project, safety for people and property is most important. Any metallic conduit should be grounded/bonded to the electrical grounding system. For the Project • Material List with Costs • References • Diagrams • Planning and Research • Dimensions • Title and Labels • Pictures (if exhibiting a report or poster) • Record Sheet Nine Common Types of Electrical Conduit 1. Galvanized Rigid Conduit A conduit made from galvanized steel tubing is commonly referred to as a rigid conduit. The thickness of a galvanized rigid (GR) conduit protects the electrical wiring from being hit and allows it to be threaded. 2. Electrical Metallic Tubing An electrical metallic tubing (EMT) conduit is made of steel; in some cases aluminum is also used. EMT is cheaper than a galvanized rigid conduit and lighter than a GR conduit. EMT is also a very popular material because it can be bent to specific radius and directions.

    Page 26 1. CONDUCTORS Conductors are defined as materials that easily allow the flow of _________. Metals are _______ conductors while insulators are ______ . The 2 common metals used for conductors in the electrical trade are: ___________ and ______________. Aluminium has become more prevalent for larger C.S.A. conductors as it is cheaper and lighter but more brittle than copper. Current/ Copper/ Aluminium Thermoplastic-sheathed cable (TPS) consists of an outer toughened sheath of polyvinyl chloride (PVC) (the thermoplastic element) covering one or more individual cables which are PVC insulated annealed copper conductors. It is a commonly used type of wiring for residential and light commercial construction in many countries. The flat version of the cable with two insulated conductors and an uninsulated earth conductor all within the outer sheath is referred to as twin and earth. In mainland Europe, a round equivalent is more common. Flat cables (or festoon cables) are made in PVC and Neoprene and are used as trailing cables for cranes, open filed conveyors and shelve service devices. Flat cables offer the advantages of extremely small bending radius’s, high flexibility and minimum wastage of space. Thermoplastic-sheathed cable (TPS) consists of an outer toughened sheath of polyvinyl chloride (PVC) (the thermoplastic element) covering one or more individual cables which are PVC insulated annealed copper conductors.
