Burnham V7 SERIES manual Removal of Boiler from Skid, TS-39-26-A, TS-39-126-A

SECTION III: INSTALLATION INSTRUCTIONS

A.REMOVE CRATE — (Packaged Boilers)

1.Remove all fasteners at crate skid.

2.Lift outside container and remove all other inside protective spacers and bracing. Remove draft regulator box and miscellaneous trim bag containing safety/relief valve, and pipe fittings.

B.REMOVAL OF BOILER FROM SKID

TS-39-26-A

Fig. 7

1.Boiler is secured to base with 4 bolts, 2 on left side and 2 on right side, see Figure 7. Remove all bolts.

2.Tilt boiler to right and to rear. Using right rear leg as pivot, rotate boiler 90° in a clockwise direction, and lower left side of boiler to floor. Tilt boiler and remove crate skid. Care should be exercised to prevent damage to jacket or burner.

C.MOVE BOILER TO PERMANENT POSITION by sliding or walking.

D.INSPECT COMBUSTION TARGET WALL AND COMBUSTION CHAMBER LINER

1.OPEN FLAME OBSERVATION DOOR AND/OR BURNER SWING DOOR on front of boiler. Use flashlight to inspect target wall secured to rear section with silastic sealant. Inspect ceramic fiber blanket secured to floor of boiler with water glass adhesive. If either is damaged they must be replaced.

E.CONNECT SUPPLY AND RETURN PIPING TO HEATING SYSTEM.

CLEARANCES — Steam and hot water pipes shall have clearances of at least ½” from all combustible construction.

1.With STEAM HEATING, see Figure 8. Consult I = B = R Installation and Piping Guide No. 200.

2.With Forced Circulation HOT WATER HEATING, see Figure 9. Consult I = B = R Installation and Piping Guide No. 200.

3.Packaged boilers. Install Safety Valve in Tapping M. Use ¾ NPT x 8" nipple and ¾ NPT coupling included in trim bag. Safety Valve must be installed with spindle in vertical position.

4.Packaged boilers with Probe style LWCO. Install Limit in Tapping A using ¾ NPT x 2" nipple, ¾ NPT elbow, ¾ NPT x ¼ NPT bushing, and syphon included in trim bag. See Figure on previous page. Connect wiring harness from Low Water Cutoff. See Figure below.

TS-39-126-A

5.If this boiler is used in connection with refrigeration systems, the boiler must be installed so that the chilled medium is piped in parallel with the heating boiler using appropriate valves to prevent the chilled medium from entering the boiler, see Figure 10. Also consult I = B = R Installation and Piping Guides.

6.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.

7.Use a boiler bypass if the boiler is to be operated in a system which has a large volume or excessive radiation where low boiler water temperatures may be encountered (i.e. converted gravity circulation system, etc.).

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 11. 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 11 in order to regulate water flow for maintenance of higher boiler water temperature.

Set the by-pass and boiler supply valves to a half throttle position to start. Operate boiler until the system water temperature reaches its normal operating range.

Adjust the valves to maintain 180°F boiler water temperature. Adjust both valves simultaneously. Closing the boiler supply valve and opening the by- pass valve will raise the boiler water temperature and lower the supply temperature. Opening the boiler supply valve while closing the by-pass valve will lower the boiler water temperature and raise the supply temperature.

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