United States Stove 1800, 1600 Smoke Pipe Installation, Creosote - Formation And Need For Removal

always follow the chimney manufacturers instructions.

NOTE: Type of chimney: Class A All-Fuel also referred to as Low-Heat appliance type chimney per Uniform Mechanical Code:

Chimney, low-heat appliance type is a factory built, masonry or metal chimney suitable for removing the products of combustion from fuel-burning low-heat

appliances producing combustion gases not

in excess	of 1000°F under normal operating
conditions but capable	of producing combustion
gases of 1400°F during		intermittent
forced firing for periods up to one hour.		All
temperatures are measured at the appliance flue outlet.

highest	point of the house, or 2'
above the point at which the	chimney
is 10' from the roof.

7.The chimney should be relatively straight and vertical.

8.The portion of an all-fuel metal chimney that extends above the roof should be well secured.

9.A masonry chimney should be built on footings and not attached to the house.

10.A rain cap, complete with an animal or bird screen, should be installed on top of the chimney.

When wood is burned slowly, it produces tar and other organic vapors, which combine with expelled moisture to form creosote. The creosote vapors condense in the relatively cool chimney flue of a slow-burning fire. As a result, creosote residue accumulates on the flue lining. When ignited, this creosote makes an extremely hot fire.

The chimney connector and chimney should be inspected at least twice monthly during the heating season to determine if a creosote build-up has occurred. If creosote has accumu-

lated,	it should be removed to reduce the risk of a
chimney fire.

1.The wood furnace should be the only heating appliance using a chimney flue. One furnace per flue.

2.A masonry chimney should have a tile or stainless steel liner.

3.The masonry chimney should not have any missing mortar or loose bricks.

4.There should be no mortar or parts of the chimney blocking the chimney flue.

5.There should be a two inch clearance between any chimney (masonry or metal) and combustibles (such as the house).

6.The chimney should extend at least 2' above the

Clearances to combustible materials (i.e. paneling, ceiling tile, sheet rock, plaster, draperies, casements or wood trim, etc.) will vary with the type of flue connection used. Be sure to maintain the specified clearances for your type of installation.
