Installation

In addition to using the lowest possible temperature setting that satisfies your hot water needs, a means such as a mixing valve, should be used at hot water taps used by these people or at the water heater.

Mixing valves are available at plumbing supply or hardware stores. Follow manufacturer’s instructions for installation of the valves. Before changing the factory setting on the thermostat see table below. Using the lowest hot water temperature that meets your needs will also provide the most energy efficient oper- ation of the water heater.

Never allow small children to use a hot water tap, or to draw their own bath water. Never leave a child or handicapped person un- attended in a bathtub or shower.

NOTE: A water temperature range of 120°F - 140°F (49°C-60°C) is recommended by most dishwasher manufacturers.

Table “A”

The thermostat of the water heater has been factory set at 120° F, to reduce the risk of scald injury. It is adjustable and can be reset to the desired temperature setting. Some states have a requirement for a lower setting. If you need hotter water, follow directions for temperature adjustment, but beware of the warnings in this section.

Site Location

•Select a location near the center of the water piping system.

•Consider the exhaust vent system piping and combustion air supply requirements when selecting the water heater location. The venting system must be able to run from the water heater to the termina- tion with a minimal length and number of elbows.

•Locate the water heater near the existing gas piping. If installing a new gas line, locate the water heater to minimize the pipe length and elbows.

NOTE: This water heater must be installed according to all local and state codes or, in the absence of local and state codes, the “National Fuel Gas Code”, ANSI Z223.1(NFPA 54)-current edition.

•The water heater should be located in an area not subject to freezing temperatures. Water heaters located in unconditioned spaces (i.e., attics, basements, etc.) may require insulation of the water piping and drain piping to protect against freezing. The drain and controls must be easily accessible for oper- ation and service. Maintain proper clearances as specified on the data plate.
