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.
