| 02/02/2026 | Commercial Plumbing Standard | REQUIRES RESUBMIT | 1. The water heater instructions still have issues to be resolved. a. The drawings do not include the installation of a vent (e.g., a concentric vent, typically shown on the mechanical drawings). b. The specified tankless water heater is non-condensing, i.e. the unit does not have a condensate drain. c. The temperature and pressure relief discharge pipe may not be connected to any other pipes. d. The expansion tank may only be installed on the cold water pipe, not the hot water pipe. e. Detail 5/P1.0 shows a condensate drain for an AC unit. The drain for the specified water heater is a hose bibb. f. The drawings show the tankless water heater located in a bedroom closet. How will you maintain the required clearances from combustible materials? The manufacturers installation instructions note that the vent will be hot and can cause serious burns, and that the area around the unit must be kept clear of combustible materials. [Previous comment: The new water heater detail is for an outdoor, gas-fired, tankless water heater, but the “specification” and location of the water heater appears to be for an indoor, gas-fired, tankless water heater. Provide a specification that includes the manufacturer’s model number, the maximum natural gas load, and the type of vent (e.g., concentric vent). Revise the water heater detail per the manufacturer’s installation instructions, showing the correct locations of the cold water, hot water, and natural gas pipes. Provide a sediment trap for the gas supply, located downstream of the gas shut-off valve. Show the size, route and termination of the temperature and pressure relief (T&P), the condensate drain (if required by the manufacturer), and the water heater drain. (Note: the T&P, condensate drain, and the water heater drain pipes may not be combined.) Show the necessary modifications to the natural gas supply piping. Show the expansion tank installed per the manufacturer’s instructions (i.e., only on the cold-water pipe, between the check valve and the water heater).] 2. Comment not addressed. The specified tankless water heater has a maximum current of 4 amps, not 71 amps. [Previous comment: Revise the electrical panel schedules to reflect the electrical requirements of the tankless water heater and not the tank-type, electric water heater.] |
