NOTE: Central Boiler sizes chimneys by their inside
diameter. A 6" chimney has a 6" inside diameter and an 8"
outside diameter. An 8" chimney has an 8" inside diameter and a
10" outside diameter. A 10" chimney has a 10" inside
diameter and a 12" outside diameter. When ordering a chimney part
for a Central Boiler furnace, be sure to use the Central Boiler designated chimney
size when ordering rather than the actual measurement. For example, when
ordering a chimney cap for a Classic 6048, even though the actual outside
diameter is 10”, order the 8” chimney cap. If you do not know the proper
size for chimney parts, please call first. All returns for incorrectly
ordered parts drop shipped from Central Boiler will incur return shipping and a
20% restocking fee.
