Available from the factory as knockdown
split blocks or completely packaged

assembled units, with steel push nipples, for
easy installation.

The top or side clean out features allow
for easier cleaning, maintaining highest

operating efficiency.

Pressurized, forced draft firing requires

only a three foot vent above the roof,
without the need for a chimney, for

simple installations.
The SC and the SOT hot water boilers

provide optional tankless domestic hot water
openings for versatility.

The SCT designation indicates that an
optional, larger, tankless domestic hot water

coil can be installed in its specially designed
rear section for steam or hot water

boilers, insuring ample domestic hot

water production.

ORIENTATION

IrAqi["_iJ-l[']_l

Do not install a probe low water cut off in the boiler primary probe tapping unless the
low water cut off is equipped with a timed on and off feature. The cycled off time will

allow the probe low water cut off to sense the true water level in the boiler and eliminate
a false reading caused from sensing a foaming or surging water condition. Failure to
use a timed low water cut off could result in a failed heat exchanger.

A - Control Mounting Instructions

NOTE: Longer gauge glass and rods are required for use with the optional CG-450 Primary Probe Low Water Cut Off. The gauge

glass carton, 22-162-10, is provided with a packaged boiler. For a KD boiler the longer gauge glass carton is located in a
special Probe Low Water Cut Off Carton, 90759.

Packaged Boilers: The CG 450P LWCO, and PA404A limit are installed and wired at the factory. The boiler miscellaneous parts
carton, located within the boiler crate, contains the longer gauge glass carton 22-162-10, Gauge Valves Carton 20-105-03, fittings
end components.

KD Boilers: A separate Primary Probe Low Water Cut Off Carton, 90759 is required. This carton contains the CG450 LWCO,
22-162-10 longer glass/rods carton, 3/4" x 3" nipple, 3/4" x 3/4" x 1/4" tee, (2) 1/2" x 2" nipples and (2) 1/2" couplings. Use these

components along with those from the Steam Trim Carton and install fittings and controls per Figure 2.
NOTE: The PA404A limit and siphon are not included as part of a standard KD boiler offering for ECT model boilers.

NOTE: For SCT model boilers, mount controls & steam gauge per Figure 8 in the SC/SCT Installation, Operation & Maintenance

Manual. Install longer gauge glass & fittings per Figure 2 above.

B - Cleaning the Series EC/SC Steam Boiler with Skim Tapping

The following cleaning procedure shall be performed by a qualified service person. Refer to Figure 1 for location of skim tapping.

1. Clean the boiler as described below no later than one week after the initial start up. Cleaning will be more effective if the
boiler operates a day or two to loosen sediment and impurities in the system,

2. The boiler must be cleaned to remove any accumulation of oil, grease, sludge, etc. that may be in the system. These substances
can cause foaming and surging of the boiler water, producing an unstable water line and water carryover to the system.

WARNING: CLEANING THE BOILER REQUIRES THE USE OF VERY HOT WATER AND CORROSIVE CHEMICALS,

USE CARE WHEN HANDLING TO PREVENT INJURY.

3. Connect a 1-1/2" pipe nipple and shut off valve to skim tapping.

4. Connect a 1-1/2" drain line off of the skim valve, run to a point of safe discharge.

5. Close all valves to the system. Provide a means of continuous fresh water to the boiler for the cleaning process.

6. Open the skim valve. Fill the boiler until water begins to flow out of the valve. Shut off fill valve.

7. Use common washing soda (such as Arm and Hammer Super Washing Soda). Mix the soda with water in a 10 quart pail and

pour into the boiler through the safety valve tapping. Mix a proportion of one (1) pound of washing soda for each 800 square

feet EDR net boiler rating.

CAUTION: DO NOT LEAVE THE BOILER UNATTENDED WHILE FIRING, TAKE GREAT CARE NOT TO ALLOW THE

WATER LEVEL TO DROP BELOW THE BOTTOM OF THE GAUGE GLASS OR TO ALLOW FRESH WATER
MAKEUP TO FLOW IN TOO FAST. THIS WILL AVOID THE POSSIBILITY OF CAUSING THE BOILER

SECTIONS TO FRACTURE.

8. Turn burner on and allow the boiler water to heat up to just below steaming (180 to 200 degrees F). Cycle the burner to

maintain temperature during skimming. Do not allow the boiler to steam. Steaming mixes up the contaminants in the water
instead of floating them at the surface.

9. Open the make-up water valve to continuously feed water to the boiler. Allow water to flow out of the skim tapping.

10. Continue skimming the boiler until the water flowing from the skim tapping flows clear. This will take some time, possibly
several hours for a dirty system.

11. After skimming is complete, close the skim valve and turn off the boiler.

12. Close the make-up water valve and open the boiler drain valve.

13. Drain the boiler completely. Refill and drain again one or two times to make sure all of the soda has been washed out.

14. Restore piping to normal. Pipe a nipple and cap in the skim valve.

15. NOTE: If the gauge glass becomes dirty again, this indicates more contaminants have worked loose in the system. Repeat

the cleaning and skimming process as needed to clean the system.

C - Wiring

NOTE: Burner disconnect is not applicable on Series SC/SCT.
