Step 4. From this position the door can be swung clear of the vertical circulator return piping to provide full access to the combustion chamber and burner head (see Figure 11B, Position 3).

2.Perform routine inspection, service or cleaning as necessary.

3.To close Burner Swing Door (see Figures 11A and 11B):

Step 1. From the fully open position, rotate Burner Swing Door toward the closed position. Make sure that the articulated hinge is rotated to the extreme left position to allow the door to clear the vertical circulator return piping as shown in Figure 11B, Position 2.

Step 2. Grasp the door's left side hinge flange in your left hand and place your right hand under the burner air tube to lift upward. Lift the door up unto the built-in cast ramp/door rest (protruding from the bottom of the front section casting - see Figure 11A), while rotating the articulated hinge and door to the right and engaging the slot (on right side of door) unto the 5/16" stud protruding from the front section.

Step 3. Use one hand to help hold door in position by lifting up on rear burner housing or applying pressure directly to the door while re-installing the securing hardware with your opposite hand.

Always install right side latching hardware (5/16" flange nut and flat washer) first, then install left side hinge hardware (5/16" x 3- 1/2" lg. hex head flange bolt) second. Apply additional pressure while hand tightening the hardware as far as possible, then release the pressure.

NOTICE

When securing burner swing door make sure door is drawn-in equally on both sides.

Step 4. Use a hand wrench to tighten door hardware and always start with the right side flange nut first. Use an alternating tightening method from right side flange nut to left side flange bolt to tighten door equally until sealed without applying excessive torque. Never tighten left side flange bolt first or tighten either piece of hardware 100% without using the alternating tightening method described above.

Failure to follow the prescribed procedure could cause thread damage to casting or a leak in the door seal. If left side flange bolt is tightened before right side flange nut, right side of door can not be drawn-in to provide an air tight seal, as shown in Figure 11C. Applying excessive torque will only cause thread damage.
