Mount the burner

Mount fl ange(s) on air tube

This section does not apply to burners with welded fl ang-
es.
Do not install air tube on burner.
For  non-pressure  fi ring  fl ange, refer to Figure 3: Install 
gasket (item a) and fl ange  (item  c). Ignore the next 
paragraph.
For pressure-fi ring fl ange, refer to Figure 3: Slide gasket 
(item a) onto the air tube, making sure the top of the air tube 
is up. Pre-drill holes in the pressure fi ring plate (item b) to 
match the appliance studs. Slide the pressure fi ring plate 
(item  b) and fl ange  (item  c) onto the air tube as shown. 
Wrap ceramic fi ber rope around the air tube and press 
tightly into the inside diameter of the fl ange (item c).
Slide the air tube (item d) into position in the appliance 
front. Tighten the fl ange-mounting-stud nuts. Set the 
insertion of the air tube so dimension G is 1/4” nominal.
Pitch the air tube at 2° from horizontal as shown and secure 

the fl ange to the air tube.

The end of the air tube must not extend into the com-
bustion chamber unprotected unless it has been factory-
tested and specifi ed by the appliance manufacturer.
Position the end of the air tube 1/4” back from fl ush with 
the refractory inside entry wall to prevent damage from 
overheating.

Mount air tube to burner

Remove the rear access door from the back of the burner 
for improved access to the interior.
Attach the air tube to the burner with the bolts and acorn 
nuts provided. The acorn nuts must go on the outside of the 
burner, with the bolts inserted from the inside.

Install nozzle

See Figure 4. Install the oil nozzle in the nozzle adapter.  
Use a 3/4” open-end wrench to steady the nozzle adapter 
and a 5/8” open-end wrench to turn the nozzle. Tighten 
securely but do not over-tighten.
Check, and adjust if necessary, the critical dimensions P, 
Q, R and S shown in the drawing. Verify that the oil tube 
assembly and electrodes are in good condition, with no 
cracks or damage.
