INSTALLATION
WARNING: To avoid electrical shock hazard, boilers must be suitably grounded to earth.
1.The boiler should be mounted on a solid level foundation. Note: When installing boiler, allow sufficient room (21” minimum) to facilitate removal of elements if and when necessary.
2.WARNING: A minimum distance of 18” between boil- er and any combustible material must be maintained.
3.Complete all piping to boiler. Connect water line to tagged fitting on the motor and pump assembly, if used, or to tagged fitting on water control feeder.
4.When any type of feed other than a pump feed is used — the exist- ing water supply must be 10 pounds greater than the boiler operat- ing pressure to assure water supply maintains proper water level in boiler. Otherwise, lack of water can cause heater failure. Keep feed
water line valves open at all times except during blowdown.
5.All water feed systems are connected to water inlet check valve.
6.Connect steam line (with Globe valve) to boiler steam outlet. Valve should be placed as close as possible to boiler outlet and sized per label on boiler.
7.To insure maximum efficiency of supplied kW, all piping from outlet should be insulated.
8.Drain and relief valve piping should be in accordance with state and local codes. Floor drain to be provided directly below unit.
9.All electrical wiring should be done by licensed electrician in accordance with national and local electrical codes.
10.If pump is located less than 30 feet from boiler, a second check valve is required.
