E.CLEAN THE BOILER (STEAM BOILERS ONLY)

1.Clean the boiler within one week after initial start-up. Cleaning will be more effective if boiler operates a day or two to loosen sediment and impurities in system.

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

Cleaning the boiler requires the use

WARNING of very hot water and corrosive chemicals. Use care when handling to prevent injury.

3.Connect a skim valve off the 1-1/2 NPT skim tapping on rear of boiler. See Figure 7.1 (Section 7) for skim tapping location. Run a 1-1/2 NPT drain line off skim valve to a point of safe discharge.

4.Provide a means of supplying continuous fresh water to the boiler for the cleaning process.

5.Use common washing soda, such as Arm and Hammer Super Washing Soda. Mix 1/2 pound of soda with water in a 10 quart pail. Pour the mixture into the boiler through the safety relief valve tapping.

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

BURNER SETUP & BOILER OPERATION

Do not leave boiler unattended while CAUTION firing burner. Operating boiler with

water below minimum permissible water level may fracture sections.

7.Turn on burner. Allow boiler water to heat up to just below steaming (180 - 200°F). Do not allow boiler to steam; steaming mixes up contaminants instead of floating them at surface.

8.Open make-up water valve to continually feed water to boiler. Adjust flow to maintain water temperature at 180 - 200°F.

Do not allow make-up water to flow CAUTION too fast. Excessive quantities of cold

water may fracture sections.

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

10.Turn off burner, close make-up water valve.

11.Drain boiler completely. Refill and drain one or two times to wash out all washing soda.

12.Remove skim valve and piping. Pipe a nipple and cap in the skim valve.

If gauge glass becomes dirty more NOTICE contaminants have worked loose in

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