	kg/cm2) water pressure.
D	Drain - Pipe full 2” (51mm) IPS to flush floor drain
	capable of receiving water flowing at a max rate
	of 5 gal. (19 liters) per minute. DO NOT MAKE
	SOLID CONNECTION TO FLOOR DRAIN.
EC	Electrical Connection - 120 volt A.C. 60Hz, 1/2”
	(13mm) conduit connection or equivalent. Use
	wire suitable for a least 90oC. Amp for 115 steam
	generator controls is 2 amps.
ST	Steam Take-off - Connection for operation of ad-
	jacent steam powered equipment.

NOTES: If equipment is installed where elevation exceeds 2,000 feet (609.6 meters) above sea level, specify installa- tion altitude so that proper gas orifices can be provided.

The only available space to supply utilities to the gas boiler is the 6” (152mm) space between the floor and the cabinet. Allow 3” (76mm) space from side wall and 6” (152mm) from real wall if adjoining walls are combustible.

CAUTION: Before connecting water to this unit, water sup- ply should be analyzed to make sure hardness is no greater than 2.0 grains and pH level is within the range of 7.0-8.5. Water which fails to meet these standards should be treated by installation of water conditioner. EQUIPMENT FAILURE CAUSED BY INADEQUATE WATER QUALITY IS NOT COVERED UNDER WARRANTY.

WASTE LINE INSTALLATION: The drain port of the unit is marked with a colored tag and is located at the lower rear left side of the boiler as viewed from the front. This exhaust line may be left open if the boiler has to be situated in a tiled floor depression or a tiled curb section that is equipped with drain facilities. If this is not the case, then a 2” (51mm) NPT. drain line must be connected to divert the exhaust to the floor drain. If it is necessary to use more than three elbows, increase the size of the waste line accordingly.
