Maintenance
The spiral chamber is basically
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 material only.
