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 demand, the spiral chamber will need to be cleaned. To
clean the spiral chamber, remove the stovepipe and scrape any creosote or debris from the top and
front of the chamber. The rear of the chamber should not have much accumulation. If it does, clean it
out.
NOTE: 1/4” to 1/2” of creosote in the spiral chamber is normal.
The pipes inside the firebox will accumulate creosote if the demand for heat is too low, when
burning wood. 1/8” to 1/4” of creosote is normal on the pipes and firebox walls. If more creosote has
accumulated, it should be scraped off of these surfaces.
NOTE: Creosote in the firebox can be burned off by burning coal for a few days.
The fire bricks 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 before any further burning occurs. The firebricks used in
the Trident Boiler are available for replacement from your Harman dealer.
Gaskets on the doors are there to regulate air to the firebox. If a gasket is failing, you’ll notice
difficulty in controlling the fire. Inspect the gaskets regularly, and replace with Harman supplied mate-
rial only.
