Firebox / Base Connector Clamps
Principles of the Firebox / Base Connector Clamps
To allow easy separation of the firebox / water jacket assembly and the base, if repairs are
needed to either assembly
Firebrick
Principles of the Firebrick
Once heated, the firebricks hold heat for a long
period of time. This creates a warm firebox between
cycles. Because of this heat, when the combustion
air blowers start, the fire inside the firebox can
re-ignite and reach the smoke burning temperature of
1100 degrees Fahrenheit much faster.
Removal and Replacement
1) Let the fire go out and allow the ashes to cool
completely. Remove the ashes from the firebox.
2) Crawl into the firebox.
3) Remove the black, high temperature silicone bead at the bottom of the firebrick.
4) Using a pry-bar, remove the broken brick.
5) Replace the broken brick.
6) Apply a new bead of high temperature silicone along the base of the brick.
Standard Grates
Principles of the Standard Grates
Grates allow combustion air from the combustion
air blowers to pass from below the grates, up
through the grates, through a shallow depth of
coals and then to the bottom of the burning fire.
This way the coal will burn completely into a fine
powder that will flow through the grates into the ash
pan. The embers will be more apt to ignite and set
the wood ablaze when there is airflow around them.
Maintenance/Result
1) Never make the slots in the grates wider than factory dimensions. If hot coals can
pass through the grates, warping of the grates may result.
2) Make sure the grates are always resting in the grooves of the ash pit. If the grates
move out of place, it may result in hot wood slipping under the grates causing warp
age of the grates.
3) Make sure the narrow side of the slot is next to the fire.
4) Replace broken grates immediately or a chain reaction of broken grates may result.
