These kits allow for separation of the air supply pipe from the pipe that discharges the
exhaust gasses. Consequently it is possible to extend the
fl ue system to a greater dis-
tance than that provided by the standard coaxial horizontal fl ue.
If either an additional 45° or 90° accessory elbow is used then the maximum permis-
sible lenght of either pipe must be reduced by 3.0 ft or 5.4 ft respectively. The sum of the
lenghts of the two horizontal part must be less than 49. ft.
Installation:
• Drill holes B & C (on the wall template) through the outside wall Drill hole C (on the
wall template) through the outside wall that is less than 18”thick.
• Cut the pipes as necessary so that no more than 6” of intake pipe protrudes from the
house and the exhaust pipe is a minimum of 4 inches longer than the intake pipe.
• Slide the Intake and exhaust pipes through the respective holes.
• Slide one rubber wall trim piece on each pipe from inside and one from outside.
• Attach each collar to the boiler with the gasket and screws provided.
• Insert each elbow into its corresponding collar.
• Connect each pipe to its corresponding elbow (as shown in the diagram).
• Secure end cap on the intake and exhaust pipe outside the house.
