Chimneys perform two functions.

1. As a means of exhausting smoke and flue gasses which are the result of fuel combustion.

2. The chimney provides “draft” which allows oxygen to be continuously introduced into the appli-

ance, so that proper combustion is possible.

As of April 1, l987 all stoves should be installed using a factory built chimney that meets the “Type HT”

requirement of UL 103 (when using a factory built chimney).

Note: your boiler does not create draft. Draft is a function of the chimney. A minimum of 0.06 w.c,

(measured in water column) is required for proper drafting to prevent back-puffing, smoke spillage, and

to maximize performance. (Gauges to measure chimney draft are readily available at furnace shops and

are economical to purchase or rent.)

IMPORTANT INSTALLATION POINTS

1. Size the chimney flue to the furnace pipe. ( 8” outlet pipe = 8” chimney flue).

2. Use elbows only as necessary. Elbows reduce draft, no more than two should be used in any

chimney.

3. Make sure all horizontal runs of connector pipe have a minimum outward rise of 1/4” per hori-

zontal foot. This allows any condensation or creosote buildup to run back into the firebox.

Masonry Chimneys will not always work

with the Seton boiler

Before using an existing masonry chimney, clean the

chimney, inspect the flue liner and make any repairs

needed to be sure it is safe to use. Make repairs before

attaching the boiler.

If the connector stove pipe must go through a combusti-

ble wall before entering the masonry chimney, consult a

qualified mason or chimney dealer. The installation

must conform to local building and fire codes and latest

edition of NFPA 211.

Do not connect this boiler into the same chimney flue as

the fireplace, gas appliance, or a flue connected with

any other furnace or boiler.

USE A CHINA HAT TYPE
