Note: 
The authority having jurisdiction may require that a licensed professional perform certain tasks outlined in this detail.
TitleSpecification(s)Objective(s)
7.8103.1a
Health and safety

Combustion safety testing will be performed in accordance with the Health and Safety Chapter of the Standard Work Specifications for Single Family Housing or other equivalent practice

Electrical components will be verified to comply with NEC NEC National Electrical Code (e.g., no electrical box connector, no disconnect, improperly sized breaker and wire)

Identify potential health and safety issues

7.8103.1b
Visual inspection

Inspection will be conducted to show compliance with the IRC IRC International Residential Code , including but not limited to:

  • Water or fuel leaks
  • Damaged wiring
  • Venting issues with draft and condensation (e.g., soot, rusting of flue pipe, burned paint or wires, efflorescence Efflorescence Deposits of crystals or salts left attached to masonry materials after moisture has evaporated off of the surface )
  • Corrosion (e.g., rust, mineral deposits)
  • General condition of components

Determine needed repairs or maintenance

7.8103.1c
Thermal efficiency

Water heater storage tanks shall have a minimum R-value of R-24, unless the SIR to add insulation is less than 1.0

Added insulation will not obstruct the unit's draft diverter, pressure relief valve, thermostats, hi-limit switch Hi-limit switch A protective electronic switch that keeps a burner from continuing to operate and damage the appliance , plumbing pipes or elements, and thermostat access plates

The first 6' of inlet and outlet piping will be insulated in accordance with IRC IRC International Residential Code or local requirements, whichever is greater

Reduce standby losses from near tank piping and storage tank

Ensure insulation does not make contact with flue gas venting

7.8103.1e
Temperature and pressure relief valve

Correct temperature and pressure relief valve will be installed in compliance with IRC IRC International Residential Code and according to manufacturer specifications

Temperature and pressure relief valve discharge tube will be installed in accordance with IRC IRC International Residential Code

Discharge excessive energy (pressure or temperature) from storage tank to safe location

7.8103.1f
Maintenance records

Occupants will be advised to keep records of all maintenance done to their system

Copies of or access to installation and operation manuals will be provided

Provide a history of system installation and maintenance to improve chance of successful future maintenance or repair

7.8103.1g
Occupant safety

Carbon monoxide ( CO CO Carbon monoxide ) alarms will be installed in each dwelling in accordance with ASHRAE ASHRAE American Society of Heating, Refrigerating and Air-Conditioning Engineers, www.ashrae.org 62.2 and authority having local jurisdiction

Occupant will be provided information regarding the health effects and risk of high CO CO Carbon monoxide concentrations as well as a list of monitors that can provide more detail regarding CO CO Carbon monoxide levels

Ensure occupant life safety

Inform occupant regarding possible CO CO Carbon monoxide hazards

7.8103.1h
Occupant education

Completed work will be reviewed

Occupants will be educated on the safe and efficient operation and maintenance of the system, including:

  • Adjustment of water temperature and target temperature in accordance with local code
  • Periodic drain and flush
  • Periodic inspection, maintenance, or replacement of anode rod

Ensure occupant is informed of the safe, efficient operation and maintenance of the system
