B. Piping-Type Heat Traps: Field-fabricated piping arrangement according to
ASHRAE/IESNA 90.1 or ASHRAE 90.2.
PART 3 - EXECUTION
3.01 WATER HEATER INSTALLATION
A. Install water heaters level and plumb, according to layout drawings, original design,
and referenced standards. Maintain manufacturer's recommended clearances.
Arrange units so controls and devices needing service are accessible.
B. Install combination temperature and pressure relief valves in top portion of storage
tanks. Use relief valves with sensing elements that extend into tanks. Extend
commercial-water-heater relief-valve outlet, with drain piping same as domestic
water piping in continuous downward pitch, and discharge by positive air gap onto
closest floor drain.
C. Install water-heater drain piping as indirect waste to spill by positive air gap into
open drains or over floor drains. Install hose-end drain valves at low points in water
piping for water heaters that do not have tank drains. Refer to Division 22 Section
“Water Distribution Piping Specialties” for hose-end drain valves.
D. Install thermometer on inlet and outlet piping of water heaters.
