Cold Water - 3/8" (
10mm
) NPT for cold water to boiler.
Cold water lines will have a maximum of 50 PSI
(

2
) and a minimum of 25 PSI (
1.8 kg/cw
2
) water
pressure.
Cold Water - 3/8" (

2
) water pressure.
Drain - Pipe full 2" (50mm) I.P.S. to flush floor drain capable
of receiving water flowing at a maximum rate of 5 gallons
(19 liters) per minute. DO NOT MAKE SOLID CONNECTION
TO FLOOR DRAIN.
Steam Take-off - Connection for operation of adjacent
steam powered equipment.
NOTES:
If equipment is installed where elevation exceeds 2,000
feet (
609.6 meters
) above sea level, specify installation 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 supply
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.
DRAIN 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.
