III) INSTALLATION
WARNING
Excessive Weight Hazard
Use two or more people to move and install storage booster tank. Failure to do so can result in back or other injury.
CAUTION
Hydrogen gas can be produced in a hot water system served by this storage tank that has not been used for a long period of time (generally two (2) weeks or more).
Hydrogen gas is extremely flammable and can ignite when exposed to a spark or flame. To reduce the risk of injury under these conditions, it is recommended that the hot water faucet be opened for several minutes at the kitchen sink before using any electrical appliance con- nected to the hot water system. Use caution in opening faucets. When hydrogen is present, there will probably be an unusual sound such as air escaping through the pipe as the water begins to flow. There should be no smoking or open flame near the faucet at the time it is open.
II) SAFETY
Relief Valve Requirements
WARNING
For protection against excessive temperatures and pres- sure, install temperature and pressure protective equip- ment required by local codes, but no less than a combi- nation Temperature and Pressure (T&P) Relief Valve cer- tified as meeting the requirements for Relief Valves and
Automatic Gas Shutoff Devices for Hot Water Supply Systems, ANSI Z21.22, by a nationally recognized test- ing laboratory that maintains periodic inspection of pro- duction of listed equipment or materials. The valve shall be marked with a maximum set pressure not to exceed the maximum working pressure of the storage tank. The T&P valve shall be rated for the BTU INPUT of the entire system.This T&P valve may be in addition to any T&P valve that is required on the boiler, or other energy supply system. Install the valve into the opening provided on the storage tank, or other approved system location. Provide tubing so that any discharge from the valve will exit within 152mm (6 in.) above, or any distance below the structur- al floor and cannot contact any live electrical part. The end of the relief pipe opening should terminate near the floor drain or other suitable location. Do not place a valve(s) or any other blockage or restrictions between the tank and the T&P valve.
T&P Valve Check
Inspect the relief valve annually to ensure proper operation. This involves opening the valve to check that it is flowing freely and that there are no blockages and letting it snap shut (see “MAINTENANCE” section).
Local Codes
The installation of this storage tank must be In accordance with these Instructions and all applicable local codes.
Location
IMPORTANT:
This storage booster tank must be installed strictly in accordance with the instructions enclosed, and local elec- trical, fuel and building codes. It is possible that connec- tions to the tank, or the tank itself, may develop leaks. IT IS THEREFORE IMPERATIVE that the storage booster tank be installed so that any leakage of the tank or relat- ed water piping is directed to an adequate drain in such a manner that it cannot damage the building, furniture, floor covering, adjacent areas, lower floors of the structure or other property subject to water damage. This is particular- ly important if the tank is installed in a
Locate the storage tank in a clean dry area close to the water heating source and preferably central to the piping system. Adequate clearance for accessibility to permit main-
