15. CONTROL LOCATIONS
NOTE
Jacket front panel should be in place before controls on front of front section are installed.
Refer to FIGURE 11 showing locations recommended for steam and water boiler limit and operating controls. Note the requirement for an operating temperature control whenever a tankless heater is called for. This is in addition to pressure limit controls and other operating controls on steam boilers.
NOTE
On steam boilers the 1" close nipple and 1" x 1/4" reducing coupling for operating control should be installed prior to jacket top panels.
16. JACKET
Jacket assembly details are contained in a separate instruction booklet.
17. SAFETY AND RELIEF VALVES
Safety and relief valves sized on the output rating of each boiler size are furnished along with the necessary pipe and fittings for installation in the back section. The valve discharge connections should be piped to a location where people will not be exposed to hot vapor or liquid. Any discharge piping should be supported so as to prevent exerting any strain on the valve body by the weight of the piping. See FIGURE 10.
