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 17,
Manufactured Chimney Installation and Figure 18
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 200 Furnace, the require
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 200
add-on units, 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.
