200,000 BTU boiler.

G1 Gas Connection - 1” (25mm) N.P.T. female for

300,000 BTU boiler.

CW1 Cold Water - 3/8” (10mm) NPT for cold water to

boiler. Cold water lines will have a maximum of
50 PSI (3.5kg/cw2) and a minimum of 25 PSI
(1.8 kg/cw2) water pressure.

CW2 Cold Water - 3/8” (10mm) NPT for cold water to

condenser. Cold water lines will have a maxi­mum of 50 PSI (3.5kg/cw2) and a minimum of
25 PSI (1.8 kg/cw2) water pressure.

D Drain - Pipe full 2” (50mm) NPT to ush oor

drain capable of receiving water owing at a

maximum rate of 5 gallons (19 liters) per min­ute. DO NOT MAKE SOLID CONNECTION TO
FLOOR DRAIN.

EC Electrical Connection - 120 Volts AC, 60 Hz, single

phase, and a 9 foot Power Cord/NEMA 5-15.

ST Steam Take-off - Connection for operations of

adjacent steam powered equipment. Requires

steam take-off kit (optional at extra cost).

DIMENSIONS ARE IN INCHES [MM]

OPERATION WILL BE BY

Gas red, A.S.M.E. constructed and National Board Reg-

2

istered, 15 PSI (1 kg/cm

) steam boiler rated at 200,000

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 orices can be provided.

The only available space to supply utilities to the gas

boiler is the 6” (152mm) space between the oor 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 MATERI­ALS 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 Chlorides: <25 ppm
Silica: <13 ppm pH: 7.0 - 8.5
Chloramine: <0.2 ppm Chlorine: <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.
