c. Initial Air Band Setting

i. The nozzle size in GPH INPUT is printed

directly on the air band. Loosen the locking

screw, move the air band until the pointer

on the air shutter and housing lines up with

the appropriate GPH INPUT. Tighten the

locking screws.

ii. The Elite burners use calibrated air bands

marked in nozzle sizes. Models EZ-1HP

and EZ-2HP have air bands calibrated to

deliver the proper amount of air for their

speciﬁ c pump pressure. The air bands on

H.P. models are designed to be set by the

rating stamped on the nozzle.

iii. The burner is now set at the approximate

air band setting for the gallonage indicated.

During ﬁ nal adjustment, using combustion

testing equipment, the air band may need

minor adjustment to achieve the desired

efﬁ ciency.

Water Boilers Only

Select the proper oil nozzle for the installation.

Burners for knockdown V8 water boilers are

shipped with the high (standard) input oil nozzle

installed in the burner.

A second oil nozzle for the lower (minimum)

ﬁ ring rate is shipped loose for the V83 - V86

models, attached to the burner. Either nozzle

may be used with water boilers. The lower

(minimum) input nozzle will provide greater

boiler efﬁ ciency. However, boiler output will be

reduced. Refer to Table 1B for ﬁ ring rates. If

the higher rate is desired, inspect the installed

nozzle and assure that the nozzle is the correct

size and type as speciﬁ ed in Table 6 of this

manual. The nozzle input is stamped on the hex

ﬂ at of the nozzle.

If the lower (minimum) input is desired, remove

the nozzle which was factory installed. Locate

the lower (minimum) ﬁ ring rate nozzle that is

supplied loose. Conﬁ rm the nozzle is the proper

size and type for the lower ﬁ ring rate as speciﬁ ed

in Table 6 of this manual. Install the proper

nozzle in the burner nozzle adaptor.

Refer to Step 7a for burner drawer assembly

removal.

M. INSTALL RIELLO OIL BURNER. (See Figure 7).

Follow instructions in Paragraph J, Steps 1 through 6.

7. Install oil nozzle in burner, inspect electrodes and

head setting.

Steam Boilers Only

Steam boilers must use the lower input

nozzle. The lower input nozzle will provide

greater boiler efﬁ ciency and for steam

boilers, reduce boiler corrosion. However,

boiler output will be reduced.

Burners for knockdown V83 - V86 steam

boilers are shipped with the lower (standard)

ﬁ ring rate nozzle installed. Knockdown

V87 - V89 boilers are provided with one

nozzle, installed in the burner, that provides

the same ﬁ ring rate as the water boiler of the

same size.

a. Installation/Removal of Drawer assembly, refer

to Figure 7B.

Figure 7B: Installation/Removal of Drawer Assembly

i. Removal:

• Disconnect oil delivery tube nut from

pump.

• Loosen SCREW (3), and then unplug

PRIMARY CONTROL (1) by carefully

pulling it back and then up.

• Remove the AIR TUBE COVER

PLATE (5) by loosening the retaining

SCREW (4) (Two SCREWS-Model F5).

• Loosen SCREW (2), and then slide the

complete drawer assembly out of the

combustion head as shown.

ii. Installation:

To insert drawer assembly, reverse the

procedure in Step i above.

b. Nozzle Replacement, refer to Figure 7C.
