6 ii. Pre-installation considerations inspect shipment carefully for signs of damage. All equipment is carefully inspected and packed. Ecr’s responsibility ceases upon delivery of the water heater to the carrier in good condition. Any claims for damage or shortage, must be filed immediately against ...
7 1. Circulator sizing. Refer to table 2 for the minimum flow through the water heater coil and the pressure drop at minimum flow. Calculate the pressure drop across all piping and fittings connected to the water heater zone. Be sure to include all zone valves, check valves, and shut-off valves. It ...
8 c. Locating the water heater. The water heater should be located in an area where water leakage from the tank or connections will not result in damage to areas adjacent to the water heater or to lower floors of the structure. When such a location can not be avoided, a suit- able drain pan must be ...
9 f. Water quality improper water quality will reduce the expected life of the water heater. Hard water, sediment, high or low ph, and high levels of chlorides in the domestic water should be avoided. Sediment and hard water will eventually coat the heating coil inside the water heater and reduce th...
10 b. Water boiler piping. See figures 2 and 3. 1. Determine where the boiler, the space heating, and the water heater connections should be made based on the type of piping system that is either in place, or is to be installed for a new hydronic system installation. See figure 2, boiler water pipin...
