American Water 100327720 40 Gal Short Gas Water Heater

Product Description

The AMERICAN WATER 100327720 is a 40-gallon short natural gas water heater designed for residential hot water supply systems. Measuring 22 inches in diameter and 51.5 inches in height, this short-profile unit fits in installations where vertical clearance is limited, such as low-ceiling utility rooms and crawl-space mechanical areas. Rated for natural gas fuel, it is installed by licensed plumbers or qualified gas-service technicians. At 146 pounds, the unit requires two-person handling during rough-in. The short form factor makes it a practical choice where a standard-height 40-gallon tank would not fit.

This water heater is suited for residential applications requiring a compact natural gas unit with standard 40-gallon storage capacity. The short profile is commonly specified in replacement scenarios where the existing footprint and ceiling height restrict a full-height tank. It is appropriate for single-family homes and light-duty residential service where natural gas supply is available at the installation point.

Key Features

• 40-gallon storage capacity in a short-profile cabinet
• Natural gas fuel type for use where gas service is available
• 22-inch diameter fits standard water heater alcoves and closets
• 51.5-inch overall height accommodates low-clearance mechanical spaces

Compatibility

Designed as an OEM-style replacement or new-installation natural gas water heater for residential plumbing systems requiring a short 40-gallon gas-fired storage tank.

Installation Notes

Installation must be performed by a licensed plumber or qualified gas-service technician in accordance with local plumbing codes and the International Fuel Gas Code (IFGC). Shut off the gas supply and cold water inlet before disconnecting any existing unit. All gas connections must be leak-tested with approved solution before restoring service. Do not operate the unit before the tank is fully filled with water.
