OPERATION WILL BE BY
Gas fired, A.S.M.E. constructed and National Board Reg-
istered, 15 PSI (1 kg/cm
BTU
Notes: If equipment is installed where elevation exceeds
2,000 feet (609.6 meters) above sea level, specify instal-
lation 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 rear wall if adjoining walls are combustible.
PVC & CPVC PIPE ARE NOT ACCEPTABLE MATERI-
ALS FOR DRAINS.
CAUTION: REMOTE KETTLE OPERATION If this boiler
is feeding a remote kettle that will be more than 5 feet
(1.5 meters) away, consult factory before ordering.
WATER SUPPLY
Good quality water feed is the responsibility of the owner.
Water quality must be within the following general guide-
lines.
TDS: 40-125 ppm
Silica: <13 ppm
Chloramine: <0.2 ppm
Hardness: 35-100 ppm
The best defense against poor water quality is a water
treatment system designed to meet your water quality
conditions.
