South Carolina Heating Contractor License

Important changes in the 2021 IMC include:

• Clothes dryer exhaust terminals required to be at least 3 feet from any opening into a building.
• Polyurethane spray-applied foam on the exterior of ducts in attics and crawl spaces required to meet specific smoke and flame index limits.
• Fire and smoke dampers must be provided with approved access for inspection and maintenance.
• Refrigerant tables updated to include new refrigerants.
• Addition of condensate termination identification markings and discharge restrictions.
• Approved factory-built combination intake/exhaust terminations permitted, relaxing separation requirement.
• 30% reduction in minimum mechanical ventilation for whole-house balanced ventilation systems.
• Continuous operation requirement for manicure and pedicure station exhaust systems.
• Grease duct horizontal cleanout required within 3 feet of a horizontal discharge fan.

Key changes in the 2021 IFGC® include:

• The termination of concealed condensate piping requires marking to indicate if it is the primary drain or the secondary drain.
• Press-connect joints are acceptable for high pressure (over 5 psig) applications indoors.
• Commercial cooking appliances are not allowed within dwelling units.

Uses:

• Sizes metal ducts, lined metal ducts duct board airways, and wire helix flexible ducts.
• Converts round shapes to equivalent rectangles.
• Correlates available pressure with total effective length and friction rate (Manual D sizing calculations).
• Converts velocity into velocity pressure and vice versa.
• Corrects for altitude and temperature

This part of the System Design Manual presents data and examples to guide the engineer in practical design and layout of normal air conditioning piping systems.

High Pressure Boilers continues to be the leading resource for preparing for high pressure boiler operator and facility operating engineer licensing. This textbook provides a comprehensive overview of the safe and efficient operation of high pressure steam boilers and related equipment. The latest combustion control technology, as well as EPA regulations and their implications, are covered in this edition. Each chapter includes case studies to enhance learning as well as a separate chapter with test-taking tips and six sample exams.

Low Pressure Boilers is the leading resource for preparing for low pressure boiler operator and facility operating engineer licensing. This textbook provides a comprehensive overview of the latest information on the safe and efficient operation of low pressure steam and hot water boilers, cooling systems, and related equipment. Each chapter is divided into sections to aid comprehension of key concepts. To assist with preparing for a licensing exam, a separate chapter with test-taking tips and a sample exam is included.

Manual J 8th Edition is the national ANSI recognized standard for producing HVAC equipment sizing loads for single-family detached homes, small multi-unit structures, condominiums, town houses, and manufactured homes. A proper load calculation, performed in accordance with the Manual J 8th Edition procedure, is required by national building codes and most state and local jurisdictions.

The New Fifth Edition of Manual N® details the load calculation procedure that addresses the advances in the commercial construction industry: new materials, methods of assembly, and operational requirements. It provides instruction to help contractors and designers satisfy new, and often conflicting, energy, ventilation, and comfort requirements. The new Manual N is divided into four sections providing both a quick and comprehensive procedure for commercial load calculation.

• Section 1 Abridged Procedure: Basic instructions to perform commercial load calculations, on buildings of three stories or less. Supports a simplified hand calculation.
• Section 2 Advanced Topics: Provides enhanced procedures, capabilities, and sensitivities (requires computer software to process).
• Section 3 Tables: Provides input for the worksheets and determinations needed for the abridged (N5ae) and full (N5) procedures.
• Section 4 Appendices: Provides supporting materials and details on the N5ae and N5 applications...(640 pages)

Modern Refrigeration and Air Conditioning, 22nd Edition is focused on closing the gap from students to technicians with our commitment to top-quality coverage of fundamentals and the latest technology. This classic is an excellent blend of theory, skill development, and service techniques to help you learn how to install and service refrigeration and HVAC systems.

Compact and pocket-sized, this handy reference contains thousands of facts and figures relevant to pipefitters, steamfitters-anyone concerned with layout and installation of pipe.
