CHIMNEY AND CHIMNEY CONNECTIONS

This is a very important part of your heating system. No boiler, however efficient its design, can perform satisfactorily if the chimney that serves it is inadequate. Check your chimney to make certain that it is the right size, properly constructed and in sound condition.

It is cheaper to rebuild a poor chimney than to pay excessive fuel bills. If yours is an old chimney, a new

steel liner or a new prefabricated chimney may be the best solution. The following chart shows

recommended minimum chimney sizes based on Table 3 and Figure 6 of the I=B=R Testing and Rating

Standard for Heating Boilers, Sixth Edition, June 1989.

CHIMNEY CONNECTOR AND DRAFT REGULATOR

Venting

the

boiler

requires

 

a 6" diameter

 

chimney

connector

pipe

and

using

the

draft

regulator

packed

with

the boiler.

 

Properly

 

installed,

 

the

regulator

will

control

the draft

automatically.

 

It is

better

to install it

in a

horizontal

section

of

pipe,

but

it may

be

installed

 

in an

angled

or

vertical section

of

pipe.

Make

certain

that

the "top" of

the regulator

is

at

the

top

-

and that the short pipe

section

which

holds

the

vane is

horizontal.

Even

though

locating

the

draft

regulator

 

close

to

the chimney

reduces

noise,

install

 

the

draft

regulator

as

close

as

practicable

 

to the

boiler.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

To install the chimney connector, start at the boiler with a vertical pipe and then elbow - then install the draft regulator making it horizontal. When the regulator is in place, start at the chimney and work back to the regulator. Join the two sections with a drawband. The horizontal pipe must slope up toward the chimney at least 1/4 inch per linear foot of venting. The chimney connector must not leak and must be firmly supported. Join each of the sections with at least two sheet-metal screws. Support every second section with a stovepipe wire.

Maintain a minimum vent pipe clearance of 18" from the surface of the vent to wood and other

combustible materials.
