The warranty on this water heater is in effect only when the water heater is installed and operated in
accordance with these instructions. The manufacturer of this water heater will not be liable for any
injury or property damage resulting from failure to comply with these instructions.
This water heater must be installed strictly in accordance with the instructions enclosed, and local
electrical, fuel and building codes. It is possible that connections to the water heater or the water heater
itself may develop leaks.
IT IS THEREFORE IMPERATIVE
that the water heater be installed so that any
leakage of the tank or related water piping is directed to an adequate drain in such a way that it cannot
damage the building, furniture, carpeting, adjacent areas, lower floors of the structure, or other
property subject to water damage. This is particularly important if the water heater is installed in a
multi-story building, on finished flooring, or carpeted surfaces.
DHT WILL NOT BE HELD LIABLE
for
damage caused by water from the water heater, pressure relief valve, or related fittings. Closets without
drains and carpeted areas are examples of unsuitable locations for any water heater. Select a location as
centralized within the piping system as possible.
The heater should be located in an area not subject to freezing temperatures in any location
selected. It is recommended that a suitable drain pan be installed under the water heater.
This pan shall be a minimum of 50mm (2 in.) deep and have a diameter that is a minimum of
50mm (2 in.) greater than the diameter of the water heater.
Suitable piping shall connect the drain pan to a properly operating floor drain.
SECTON 1.1: Relief Valve Requirements
FOR YOUR SAFETY:
To reduce the risk of excessive pressures and temperatures in this water heater, install temperature and
pressure protective equipment required by local codes. It should be no less than a combination
temperature and pressure relief valve certified by a nationally recognized testing laboratory that
maintains periodic inspection of production of listed equipment or materials, as meeting the latest
edition of ANSI Z21.22.
Requirements for Relief Valves and Automatic Gas Shut-off Devices for Hot Water Supply Systems:
This valve must be marked with a maximum set pressure not to exceed the marked MAXIMUM working
pressure of the water heater (150 PSI).
How to Install:
1.
Install the valve into an opening provided and marked for this purpose in the water heater.
2.
Orient it or provide tubing so that any discharge from the valve will exit only within 6 inches
above, or any distance below the structural floor and cannot contact any live electrical part.
3.
The discharge opening must not be blocked or reduced in size under any circumstances.
4.
The end of the relief pipe opening should terminate near a floor drain or other suitable location
not subject to blocking or freezing.
5.
DO NOT
thread, plug, or cap the relief pipe opening.
