Specifications — 480 Volt Boilers*
INSTALLATION
CAUTION: To avoid electrical shock hazard, boilers
must be suitably grounded to earth.
NOTE: Chromalox boilers are pre-tested before shipment; no internal
piping or wiring is necessary.
WARNING:
Substitution of compo-
nents or modification of wiring without prior consent of Chromalox,
Inc. voids warranty.
1.
Locate unit on level floor or platform.
NOTE:
A minimum dis-
tance of 60 inches from wall, other equipment, etc. must be
allowed for removal of the elements.
2.
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.
3.
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.
4.
All water feed systems are connected to supplied water inlet check
valve.
5.
Connect steam line (with Globe valve) to boiler steam outlet. Valve
should be placed as close as possible to boiler outlet.
6.
To insure maximum efficiency of supplied kw, all piping from out-
let should be insulated.
7.
Drain and relief valve piping should be in accordance with state
and local codes.
