FIREBOX AND OTHER COMPONENTS
Firebox
Principles of the Firebox
Wood is burned inside the rebox to generate heat. This heat is absorbed into the
water in the water jacket. The rebox and water jacket are one welded component
and can be replaced.
When the water is up to temperature and the combustion air blowers are off, the
rebox must be airtight.
Operation of the Firebox
Temperatures within the rebox can reach 2000 degrees Fahrenheit. Smoke exits
from the rebox into the ue. During normal operation, there will be a slight buildup
of black creosote on the rebox walls. This buildup will sometimes appear aky.
Maintenance / Result
Wood should not be thrown into the rebox in a rough manner. Creosote should
never have to be scraped off the rebox walls.
Removal and Replacement
1) Remove all wood and let the unit cool down.
2) Drain all water and disconnect main power.
3) Remove the total roof of the HEATMOR™.
4) Remove sides of the HEATMOR™.
5) Remove the doors and corners of the HEATMOR™.
6) Remove the insulation.
7) Disconnect plumbing, aquastat and high limit and all electrical from the water jacket.
8) Loosen the rebox / base connector clamps.
9) Lift the old rebox / water jacket component off the base.
10) Lift the new rebox / water jacket component onto the base.
11) Apply new silicone.
12) Reverse the above.
