Page 28

32.Tighten all sheet metal screws.

a.Install the following plates or labels which are found in the Instruction Envelope. See Fig. 23 or 24 for location.

(1)Rating Label

(2)Operating Instruction Plate (#8 SMS required to fasten)

(3)Combustible Clearance Flooring & Adequate Combustion Plate

(4)Minimum Service Clearance Label

(5)Burnham Logo – Apply to Top Panel

(6)Boiler Ventilation/For Your Safety Label

b.Proceed to Paragraph 33 (Steam Boilers) or Paragraph 34 (Water Boilers).

NOTE: IF WATER BOILER, PROCEED DIRECTLY TO Paragraph 34.

33.INSTALL STEAM TRIM AND CONTROLS, See Fig. 7 and 25.

a.Pressure Gauge is to be installed with ½” nipple and

½” x ¼” reducing coupling in ½” tapping provided in upper corner of End Section using wrench applied to square shank on back of gauge. DO NOT APPLY FORCE ON GAUGE CASE.

b.Install 67BC-2 Low Water Cut-Off or 47-2

Combination Feeder and Low Water Cut-Off in accordance with the Instructions packed with the control. ½” pipe extensions are provided and must be installed in the ½” tappings adjacent to the Pressure Gauge before the control can be mounted.

Unions are furnished with the 67BC-2 Low Water

Cut-Off for ease of installation. 1” pipe tappings have been provided in the End Sections for other types of Low Water Cut-Offs and Low Water Cut- Off & Feeder combinations. Fig. 25A illustrates the required mounting elevations for a M&M 150 and a 67M float LWCO. Figure 13C illustrates a

typical steam piping arrangement for pumped return systems.

c.

Install Gauge Glass Fittings into ends of tees used

 

to connect the 67BC-2 or 47-2 Control. If other

 

control is furnished, install Gauge Glass Fitting

 

directly into ½” pipe extensions.

d. Install Pressure Limit Controls as follows:

 

(1)

Boiler equipped with 67BC-2 Low Water Cut-

 

 

Off – Connect Pressure Limit furnished to ¼”

 

 

street ell and ¼” pigtail siphon. For installation

 

 

of second pressure limit (not furnished), bush

 

 

1½” pipe tapping in upper corner of End

 

 

Section. Connect Pressure Limit to this bushing

 

 

with ¼” pigtail siphon.

 

(2)

Boiler equipped with Low Water Cut-Off other

 

 

than (1) above or with Low Water Cut-Off

 

 

Feeder Combination – Bush 1½” pipe tapping

 

 

in upper corner of End Section and connect

 

 

Pressure Limit furnished to this bushing with

 

 

¼” pigtail siphon. For installation of second

 

 

pressure limit bush any available tapping on

 

 

opposite end section that is above normal water

 

 

line. Connect Pressure Limit to this bushing

 

 

with ¼” pigtail siphon.

 

(3)

Tighten limit controls by using wrench on hex

 

 

fitting at bottom of control.

 

(4)

The L404 Pressuretrol must be accurately

 

 

leveled for proper operation. It is level when the

 

 

leveling indicator hangs freely with its pointer

 

 

directly over the index mark inside the back

 

 

of the case. Level the controller by carefully

 

 

bending the steam trap (siphon loop).

e.

Install Pressure Safety Valve with fittings furnished,

 

into 1½” pipe tapping in upper corner of End

 

Section, see Fig. 12. DO NOT INSTALL A

 

SHUTOFF VALVE BETWEEN SAFETY VALVE

 

AND BOILER. If this boiler tapping is to be used

 

as Surface Blowoff, replace ell with tee and plug

 

open end of tee or valve off opening. Pressure

 

Safety Valve must be in leg of tee and in a vertical

 

position with handle up.

f.

Install Boiler Drain Valve and 3” x ¾” Bushing into

 

one of the two return tappings. The drain valve

 

may also be installed in return piping, but it must

 

be installed in the leg of a tee so that it is directly

 

opposite and as close as possible to the return

 

tapping. The leg of the tee must be at least 1½” pipe

 

size.

 

A Bottom Blowoff using a valve must also be

 

connected to one of the return tappings. The ¾”

 

Drain Valve may be used for Bottom Blowoff for

 

5009B or smaller boilers, since any Bottom Blowoff

 

piping or valves for 5009B or smaller boilers must

 

be at least ¾”. Bottom Blowoff piping and valves

 

for Boilers 5010B through 5021B must be at least

28

STEAM TRIM AND CONTROLS

1”. Bottom Blowoff piping and valves for 5022B

Boilers and larger must be at least 1¼”.
