Pedestal-mounted burners
1. Check the diameter of the appliance opening. If larger than 4½ inches,
rebuild the opening so the open is reduced to 4½ inches maximum.
2. Insert the air tube into the appliance opening as in Figure 4. Do not attach
air tube to housing yet.
3. Slide the tube in until the end of the tube is fl ush with, or up to ¼ inch short
of, the inside of the combustion chamber.
4. Level the air tube using a spirit level.
5. Mark the air tube position with a pen or pencil around the circumference
of the tube.
6. Remove air tube from the opening
2. Prepare site • assemble burner • mount burner

Attach air tube to housing
1. See Figure 5. Loosen the four hex set screws on the top front of the burner
chassis.
2. Open the ignitor cover plate by loosening the retainer screw on the left side
of the burner housing.
3. Swing the ignitor plate open.
4. Locate the drip hole in the burner air cone (301 burners) or throttle ring
(201 burners). Rotate the air tube so the drip hole is at the bottom.
5. Insert the air tube into the housing.
6. Make sure the air tube is inserted completely, butting against the air tube
socket ledge. If necessary, tap on the end of the air tube with a block of
wood until properly seated.

of the burner housing.
On burners with welded fl anges, you can bolt the air tube/

1. Assemble the pedestal to the burner and tighten the bolt. Insert a screw
into each of the two holes in the pedestal feet if needed to level the as-
sembly.

the same height as the center of the appliance opening.
3. Tighten the pedestal bolt.
4. Insert the burner/air tube into the appliance opening until pen/pencil line is
even with appliance front (so end of air tube is fl ush with, or slightly short
