TEMPERATURE AND PRESSURE

RELIEF VALVE

WARNING

Keep clear of the combination temperature and pressure relief valve discharge line outlet. The discharge may be hot enough to cause scald injury. The water is under pressure and may splash.For protection against excessive temperatures and pressure, install temperature and pressure protective equipment required by local codes, but not 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 requirements of the Standard for Relief Valves and Automatic Gas Shutoff Devices for Hot Water Supply Systems, ANSI Z21.22 and the Standard CAN1-4.4 Temperature, Pressure, Temperature and Pressure Relief Valves and Vacuum Relief Valves. The combination temperature and pressure relief valve must be marked with a maximum set pressure not to exceed the maximum working pressure of the water heater. The combination temperature and pressure relief valve must also have an hourly rated temperature steam BTU discharge capacity not less than the hourly rating of the water heater. The supplied combination temperature and pressure relief valve, when properly installed and unrestricted, will discharge the maximum input produced by a 240°F (116°C) boiler supply temperature. A lower boiler supply temperature will reduce the input required to be discharged in the event of excessive potable water temperatures.

Install the combination temperature and pressure relief valve into the opening provided and marked for this purpose on the water heater.

Some models may already be equipped or supplied with a temperature and pressure relief valve. Verify that the combination temperature and pressure relief valve complies with local codes. If the temperature and pressure relief valve does not comply with local codes, replace it with one that does.

NOTICE

If the boiler takes longer to heat up from a cold start than the water availability as noted above, hot water shortage may occur.

Hot water availability is based off drawing 80% of the heated tank volume at 4 gallons per minute flow rate.

The maximum heat transfer through the coil (heat input) of the water heater at 240°F boiler water supply temperature and 210°F potable water temperature is 94,100 Btu/hr for residential models and 180,300 Btu/ hr for commercial models. Potable water temperature is limited to below 210 °F and nominal water- containing capacity is below 120 gallons for all single- wall indirect models.

Accordingly, per Part HLW-101.2, Section IV of the ASME Boiler and Pressure Vessel Code, all Lochinvar Single-wall Indirect products are exempted from

compliance with the code.

GENERAL INFORMATION

FEATURES

This water heater contains the following features:

HEAT EXCHANGER — The heat exchanger (coil) has 1" NPT female fittings.
