Water Plumbing

Follow local guidelines for the length of the plumbing line in order to ensure that there is enough water pressure for all the fixtures on the line. First, calculate the effective length of the plumbing line by measuring the total length of pipe, and then adding to this 5’ for each elbow or tee in the line. Use the following chart to determine the total number of fixture units on the line, and then compare with the chart at the bottom of this page to find the pipe diameter and water pressure necessary.

Install with control valves on the inlet and outlet, and use removable unions or connectors to facilitate maintenance or service if necessary.

If the water heater is installed in a closed water system, means shall be provided to control thermal expansion. Contact the water supplier or a local plumbing inspector on how to control this situation.

Purge the water line of air, and clean the filter before initial operation.

WARNING: Do not reverse the hot outlet and cold supply line connections to the Flash Water Heater. Make sure the hot and cold lines are connected as in the FOR YOUR SAFETY section at the front of this manual.

Pressure Relief Valve

An approved pressure relief valve must be installed in any installation with this unit. The pressure relief valve must be installed on the hot line out of the unit, with no check valves or control valves between the unit and the relief valve.

The Pressure relief valve must be rated for 150 PSI, and have a discharge capacity of 185,000 BTU. Connect the discharge opening of the relief valve to a suitable drain to prevent water damage should discharge occur.

If the pressure relief valve discharges periodically, this may be due to thermal expansion in a closed water supply system. Contact the water supplier or local plumbing inspector on how to correct this situation.

Do not plug the pressure relief valve. The line should have no reduced fittings or other restrictions and should allow for complete drainage of valve and line. The pressure relief valve should be manually operated once a year to check for correct operation.

Should overheating occur or the gas supply fail to shut off, turn off the manual gas control valve to the appliance.
