CHIMney InForMatIon
The chimney is one of the most important yet most
neglected and misunderstood portions of any Sol
-
id Fuel Burning Installation. THE FURNACE SHALL
nOt be COnneCteD tO the Chimney with
Other heating DeViCes.
There are two types of Class “A” chimneys:
1. Masonry with tile liner suitable for venting resi
-
dential or building heating appliances. (See NFPA
211.)
2. Class “A” Chimney, listed or certified by a na
-
tionally recognized testing agency as suitable for
venting residential or building heating applianc
-
es. If your masonry chimney has not been used
for some time, have it inspected by a qualified
person (building inspector, fire department per
-
sonnel, etc.). If a listed or certified manufactured
chimney is to be used, make certain it is installed
in accordance with the manufacturer’s instruc
-
tions and all local and state codes. See Figure 5,
Manufactured Chimney Installation and Figure 6
of Masonry Chimney (note roof clearance) in ac
-
cordance with NFPA 211.
CoMMon CHIMney ProBLeMS
In order to have a proper operating Solid Fuel Heat
System, the chimney must be capable of providing
the draft required.
In the Vapor-Fire Model 100 Furnace, the required
draft is .04 to .06 water column (W.C.). This can be
measured using a draft gauge.
If the chimney cannot supply this constant draft, the
unit will not operate properly.
In all furnace installations using Vapor-Fire Model 100
furnaces, a barometric draft regulator must be used
and properly adjusted for proper draft. Provided – Set
to .06 W.C. by sliding wt. to #6 vertical.
