Mount the burner

Protect the Air Tube From

Overheating

Overheating could cause damage to the air tube and other combustion components lead- ing to equipment malfunction and impaired combustion performance.

yThe end of the air tube must not extend into the com- bustion chamber unprotected unless it has been facto- ry-tested and specified by the appliance manufacturer.

yPosition the end of the air tube 1/4” back from flush with the refractory inside entry wall to prevent damage from overheating.

‰Stray Light

Protect Against Stray

Light Lockout

Failure to follow these instructions could cause loss of burner operation resulting in no heat, an unplanned process interruption, work stoppage and the potential for frozen plumbing or other cold weather property damage.

yThe control must detect a dark, no-flame condition in order to start the burner or it will hold in the stray light lockout mode.

yShield the burner from direct exposure to intense light.

‰Dust and Moisture

Protect Against Dust and

Moisture

Wet, dusty environments could lead to blocked air passages, corrosion damage to components, impaired combustion performance and result in asphyxiation, explosion or fire.

yThis burner is designed for clean, dry installations.

yElectrical controls are not protected against rain or sprayed water.

yKeep the installation clear of dust, dirt, corrosive va- pors, and moisture.

yProtective covers and more frequent maintenance may be required.

‰Mount flange(s) on air tube

yThis section does not apply to burners with welded flang- es.

yDo not install air tube on burner.

yFor non-pressure firing flange, refer to Figure 4: Install gasket (item a) and flange (item d). Ignore the next paragraph.

yFor pressure-firing flange, refer to Figure 4: Slide gasket (item a) onto the air tube, making sure the top of the air tube is up. Pre-drill holes in the pressure firing plate (item b) to match the appliance studs. Slide the pressure firing plate (item b) and flange (item d) onto the air tube as shown. Wrap ceramic fiber rope (item c) around the air tube and press tightly into the inside diameter of the flange (item d).

ySlide the air tube (item e) into position in the appliance front. Tighten the flange-mounting-stud nuts. Set the insertion of the air tube so dimension G is 1/4” nominal.

yPitch the air tube at 2° from horizontal as shown and secure the flange to the air tube.
