Inspect burner and components
• Check the air tube length. Verify the usable length of the tube UTL will
be long enough (see “Mount burner in appliance”).
• Visually inspect all burner components and wiring.
• Verify that wiring is intact and leads are securely connected.
• Verify that all burner components are in good condition.
Do not install or operate the burner if any component is dam-
aged or if burner does not comply with the specifications of
Table 1, page 3, and other guidelines of this manual and the
appliance manual.
Welded-flange burners
1. Verify the bolt pattern on the appliance chamber matches the flange
pattern.
2. Verify the insertion depth (UTL) matches the depth of the appliance
opening (so the end of the air tube is flush with, or slightly short of, the
inside surface of the combustion chamber).
Assemble burner (when required)
Universal (adjustable) flange burners
1. Verify the flange mounting slots line up with the appliance bolts. See
Figure 2.
2. Slip the adjustable flange onto the air tube.
3. Measure the distance from the inside of the combustion chamber to
the outside of the appliance mounting plate.
4. Position the universal flange at this distance from the end of the air
tube.
5. Tighten the locking screws finger tight.
6. Insert the air tube/flange assembly into the appliance opening and level
the air tube with a spirit level. Adjust flange if needed.
7. The end of the air tube should be flush, or almost flush, with the inside
of the combustion chamber wall.
8. Verify the air tube is level and inserted the correct depth. Adjust if
necessary. Then tighten the flange locking screws securely.
9. Remove the flange/air tube assembly from the opening.
Pedestal mount 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 3. Do not
attach air tube to housing yet.
3. Slide the tube in until the end of the tube is flush 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.
NOTICE — 99FRD burners firing above 2.25 GPH
1. 99FRD burners are shipped with the blank air shutter (behind fuel unit)
installed. This shutter is suitable only for firing rates up to 2.25 GPH.
2. For firing rates over 2.25 GPH, obtain an open type air shutter from
your Carlin dealer. Remove the blank shutter and replace with the open
shutter.
3. The optional open air shutter is suitable for firing rates from 1.50 to
3.00 GPH.
4. To change air shutters, remove the burner fuel unit. (The fuel unit holds
the shutter in place.) Install the correct shutter and replace the fuel
unit.
