THIMBLE & CANOPY ASSEMBLY SECURED & SEALED TO SECTIONS

If this boiler ,is connected to heating coils located in air handling units where they may be exposed to refrigerated air, the boiler piping must be equipped with flow control valves to prevent gravity circulation of boiler water during the operation of the

cooling system.

If the boiler will be operated where low boiler water temperatures may be encountered (i.e. converted gravity circulation systems, etc.) the use of a boiler water bypass is recommended to maintain optimum operation.

Remove the circulator and install a pipe tee between 'the circulator and boiler return along with a

second tee in the supply piping as shown in Figure

19.

The bypass should be the same size as the supply and return lines with valves located in the bypass and supply outlet as illustrated in Figure order to regulate water flow for main-tenance of higher boiler water temperature.

Set the by-pass and boiler supply valves to a half

throttle position to start.

system water temperature is at a normal operating range.

Adjust the salves to provide 180" to 200°F supply water temperature. Opening the boiler supply valve will raise the system temperature, while opening the by-pass valve will lower the system supply temperature.

Oxygen contamination of the boiler water will cause corrosion of the iron and steel boiler components, which can lead to failure. As such, any system must be designed

to prevent oxygen absorption in the first place or prevent it from reaching the boiler. Problems caused by oxygen contamination of boiler water are not covered by Buw-

ham's standard warranty.

There are many possible causes of oxygen contamination such as

Addition of excessive make-up water as a result of system leaks.

Absorption through open tanks and fittings.

Oxygen permeable materials in the distribution system.

In order to insure long product life, oxygen sources should be eliminated. This can be accomplished by taking the following measures

Repairing system leaks to eliminate the need for addition of make-up water.

Eliminating open tanks from the system.

Eliminating and/or repairing fittings which allow oxygen absorption.

Use of non-permeable materials in the .distribution system.

Isolating the boiler from the system water by installing a heat exchanger.

A hot water boiler installed above radiation level must be provided with a low water cutoff device as part of the installation.

also lengthen the delivery of the8available hot water by mixing some cold water with the hot. In addition, savings of hot water will be achieved since the user will

not waste as much hot water while seeking water tem-

H. Allow boiler water to reach operating temperature, if

possible.

Continue to circulate the water for a few hours.

Stop firing the boiler.

Drain the system in a manner and to a location that hot water can be discharged with safety.

L. Remove plugs from all available returns and wash the

water side of the boiler as thoroughly as possible, using a high-pressure water stream.

Refill the system with fresh water.

BOILER WATER TREATMENT

Certain state and local codes may restrict the use of some of the chemicals lis'ted for cleaning and maintaining the boiler. Check with local authorities before proceeding to use these chemicals.

Add boiler water treatment compound as chromate boiler water treatment compound consisting of 95% sodium chromate and 5% sodium borate has been tested and found reliable. These tests have shown that the material, when used and maintained at the concentrations listed below, is effective in controlling and arresting corrosion. These chemicals may be purchased from any reliable chemical company.

A. Low pressur. steam boilers, such as the PF-5 Series

should be miintained with a chromate concentration of 2 ljb./100 gal. (see Table 3) of boiler water (2200 ppm). This concentration will be effective where all or practically all of the condensate is returned to the

boilers.

nezded. A

B. Hot Water Boilers.

The use of chromxte boiler water treatment compound in a water boiler involves considerations. Too high a concentration must be avoided as it may damage pump seals. Therefore, with a lower level of protection, it is necessary to take even greater free oxygen out of the system. Free oxygen can enter

from system leaks, faulty vents, or vents improperly

located with regard to pumps and from makeup water.

Hot water heating boilers should be maintained with a chromate concentration of water. See Table

Make pH or Alkalinity Test.

After boiler and system have been cleaned and refilled as previously described, test the pH of the water in the system. This can easily be done 'by drawing a small sample .of boiler water and testing with hydrion paper which is used in the same manner as litmus paper, except it gives specific readings. of the small hydrion dispenser gives the reading in pH. Hydrion paper is inexpensive and obtainable from any chemical supply house or through your local druggist. The pH should be higher than of the washout chemical (caustic soda), if necessary, to bring the pH within the specified range.

Add some

If, during normal operation, it is necessary to add water

to this boiler more frequently than once a month consult a qualified service technician to check your system for leaks. A leaky system will increase the volume of make-up water supplied to the boiler which can significantly shorten the life of the boiler. Entrained in make-up water are

dissolved minerals and oxygen. When the fresh, cool

make-up water is heated in the boiler the minerals fall out as sediment and the oxygen escapes as a gas. Both

can result in reduced boiler life. The accumulation of sediment can eventually isolate the water from contacting

the cast iron. When this happens the cast iron in that

area gets extremely hot and eventually cracks. The presence of free oxygen in the boiler creates a corrosive atmosphere which; if the concentration becomes high enough, can corrode the cast iron through from the inside. Since neither of these failure types are the result of a casting defect the warranty does not apply. Clearly it is in everyone's best interest to prevent this type of failure. The maintenance of system integrity is the best method to achieve this.

GENERAL MAINTENANCE CONSIDERATIONS

A. Keep radiators and convectors clean.

B. FLOAT TYPE LOW WATER CUTOFF

During the heating season, if an external low water cutoff is on the boiler, the blow of! valve sh,ould be opened once a month (use greater frequency where conditions warrant), to flush out the sediment chamber so the device will be free to function properly.

Low water cutoffs and water feeders should be dismantled annually by qualified personnel, to the extent necessary to insure freedom from obstructions and proper functioning of the working parts. Inspect connecting lines to boiler for accumulation of mud, scale, etc., and clean as required. Examine all visible wiring for brittle or worn insulation and make sure electrical contacts are clean and that they function properly. Give special attention to solder joints on bellows and float when this type of control is used. Check float for evidence of collapse and

check mercury bulb (where applicable) for mercury separation

Check burner and controls at least once a year. See

under Operating Instructions for control checks.

If a hot water radiator is hot at the bottom but not at

the top, it indicates that air has accumulated inside and should be vented. To vent radiator, hold small cup under air vent (located near top of radiator), open vent until water escapes and then close.

C. If much water is added to system, it is advisable to

heat system to a high temperature and vent again. This will make less venting necessary during the winter.

D. Where an expansion tank is used, make sure that neith-
