Installing the Burner (continued)
Mounting the Burner on the Hinge Bracket
ATTENTION: Burner tube components (e.g. electrodes and retention head) are factory set. Handle the
burner with extreme care so that burner components are not damaged.
1. Remove the nut from the bolt on the mounting flange of the furnace cabinet, and set it aside for
later use.
2. Lift the burner into position so the burner hinge plate is mounted on the hinge bracket on the
furnace cabinet.
3. Carefully swing the burner so the retention head enters the throat of the furnace.
4. Check the clearance between the retention head and the furnace throat. There must be at least
1/8" clearance, so the retention head is not "bumped" as you swing the burner into firing
position.
NOTE: If the retention head "bumps" the furnace throat, adjust the hinge bracket bolts
as follows:
• While supporting the burner, slightly loosen the two (2) hinge bracket bolts.
• Carefully re-position the burner so it swings freely into its firing position.
• With the burner in its firing position, re-tighten the hinge bracket bolts.

proper length.
ATTENTION: Due to adjustment of the burner hinge bracket, the oil line tubing may need to
be cut to fit properly. DO NOT lift up on the burner when installing the oil line tubing to
compensate for oil line tubing that is too long. This will place the weight of the burner on the
swivel fitting and result in leaks at the swivel fitting seal.
5. Make sure that the curl in the oil line is positioned as shown in Figure 3L so that the burner can
swing open correctly.
6. Install the oil line tubing and tighten the nuts on the compression fittings. DO NOT overtighten
