III: INSTALLATION INSTRUCTIONS

REMOVE CRATE

1. Remove all fasteners at crate skid.
2. Lift outside container and remove all other

inside protective spacers and bracing. Remove

miscellaneous steam or water trim carton.

REMOVAL OF BOILER FROM SKID

1. Boiler is secured to base with 4 carriage bolts, 2 on

left side and 2 on right side. See Figure 4. Remove

all bolts.

models, attached to the burner. Select the proper oil

nozzle for the installation. The lower input nozzle

will provide greater boiler efficiency. However,

boiler output will be reduced. Refer to Table 2 for

firing rates.

If the higher rate is desired

, inspect

the installed nozzle and assure that the nozzle is

the correct size and type as specified in Burner

Specifications, Tables 14A and 14B (at the rear of

this manual).

If a lower input is desired

, remove the nozzle

which was factory installed. Locate the lower

firing rate nozzle that is supplied loose. Confirm

the nozzle is the proper size and type for the lower

firing rate as specified in Tables 14A and 14B (at the

rear of this manual). Install the proper nozzle in the

burner nozzle adaptor.

2. ON THE BECKETT AFG BURNER, use the

following procedure to complete the inspection,

check the settings and to change the nozzle to a

lower firing rate:

a. Loosen two (2) igniter latching screws, rotate

tabs and swing open igniter about hinge.

b. Loosen knurled nut and disconnect copper

connector tube.

c. Remove nozzle line electrode assembly.
d.

If high firing rate is desired

, confirm the nozzle

is the proper size and type, refer to Table 14A

(at rear of this manual), then proceed to Item i.

below.

If a lower input is desired

, remove the nozzle

that was factory installed.

f. Remove Beckett MB(L1) or MD(V1) head.
g. Locate the desired nozzle. Refer to Table 14A

(at rear of this manual) for proper nozzle. The

nozzle must be securely installed to assure leak

free joints between the nozzle and adapter.

When installing the nozzle, be careful not to

bump or move the burner electrodes.

Note:

On the CL3-091 (0.65 GPH) burner

application, a low firing rate baffle is required.

Baffle is shipped loose with nozzles. Install

baffle per Beckett Instruction included with

baffle.

h. Reinstall Beckett MB(L1) or MD(V1) Head.
i. Inspect and measure burner electrodes. Refer

to Figure 26 for the proper electrode setting.

Readjust electrode setting to the proper

dimensions if necessary. Refer to Figure 26.

j. Reinstall nozzle line electrode assembly.
k. Connect copper connector tube.

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.

MOVE BOILER TO PERMANENT POSITION by

sliding or walking.

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.

INSPECT NOZZLE, ELECTRODES INSERTION

DEPTH AND TURBULATOR SETTING/CHANGE

FIRING RATE:
1. PACKAGED CL™ SERIES BOILERS are

shipped with the highest input oil nozzle installed

in the burner. Oil nozzles for lower firing rates

are shipped loose for the CL3-091 and CL4-175
