10. Completely assemble the 3” (80 mm) vent
lengths A, B and elbow and attach to the heater.
Put the vent collar on the 3” (80 mm) vent. All

11. Attach the vent collar to the heater. Hold the 5”
(125 mm) vent material up to the 3" (80 mm) vent
and mark the required length. Note the length
must be sufficient for a minimum of 1 1/2” (38 mm)
overlap at both ends. Cut the vent to length from
the non crimped end. Wrap the 3” (80 mm) tube
