Maintenance

The spiral chamber is basically self-cleaning. However, if there is a draft problem and you have been burning wood for a long time with little heat demand, the spiral chamber may need cleaning. Soft coal will also require more frequent cleaning. To clean, remove stovepipe and scrape the creosote from the front and top of the chamber and remove. The rear of the chamber will not accumulate creosote.

NOTE: 1/8” to 1/4” of creosote in the spiral chamber is normal. Creosote can be burned off by burning coal for a few days.

Firebricks may become cracked during the course of normal operation. A cracked brick that is still in place is still doing its job and need not be replaced immediately. If a brick is broken and has fallen out of place, it should be replaced immediately. The firebrick used in the Harman furnaces are inexpensive and easy to replace.

The blower manufacturer recommends the blower motor to be oiled once a year with 10 to 20 drops of light weight oil [check instructions packed in blower box).
