Feeder air crossover tube kit for Harman pellet stove and inserts.
Kit Includes:
- 1 x 8 1/2" of 9mm silicone tube
- 2 x Brass sleeves, and instructions.
Change Made:
Effective 4/6/09 we began incorporating a crossover tube into the feeders on all models.
This silicone tube measures 9mm inside diameter and slides onto a brass sleeve at each end in the configuration shown above.
Use this kit as a replacement for any current stove requiring the bypass to be repaired.
Why this Bypass was added to Stoves in 2009
In a very small percentage of installations, a sticky creosote residue has formed in the rear of the feeder. There is also a possibility of a flow reversal of the flue gases. The tube forces any pre-combustion air within the feeder body to be drawn through the auger shaft and directed into the firebox, eliminating any creosote from the feed system.
In some models prior to 2009, a small hole in the rear of the auger tube was introduced to correct this problem but it has become blocked with pellet fines in a few cases, reducing the effectiveness.
This new design is a far more robust method to ensure uninterrupted airflow. This is a running change in production and not a required change unless you are getting creosote developing within the feeder body which effectively jams the feed system.
