Flue as system 13
5.4 Flue gas system
The flue gas system consists of a chimney and a flue gas tube. The flue gas tube connects the pellet heating
system to the chimney. The chimney leads the flue gas from the pellet heating system out into the open.
1. Design of the chimney
The dimensions and design of the chimney is very important. The chimney must be able to ensure suffici-
ent draft to safely draw away the flue gas regardless of the status of the urnace. Low flue gas temperatu-
res can cause sooting and moisture damage on chimneys that are not insulated. or this reason moisture-
resistant chimneys (stainless steel or ceramic) should be used. An existing chimney that is not damp-re-
sistant needs to be rennovated before use. ollow guidelines below:
Furnace size Furnace
lue gas tube diameter (at urnace) inch/mm 6.3/160
lue gas temp. / rated power °
lue gas temp. / partial load °
Min. draft – full load/part load in/wc – 0.04 / – 0.02
himney size Min. Height
6in x 6in 17ft
7in x 7in 16ft
8in x 8in 16ft
6in round 19ft
7in round 17ft
Person(s) operating a pellet fired furnace is/are respon-
sible for operation in a manner that does not create a
public or private nuisance condition. The manufacturer's
distance and stack height recommendations and the re-
quirements in any applicable laws or other requirements
may not always be adequate to prevent nuisance condi-
tions due to terrain or other factors.
Recommended and UL-103HT approved chimney materials are:
a. Selkirk sure temp
b. Supervent (JSC)
c. Security chimneys (secure temp ASHT)
Use flue gas pipe from chimney to urnace as required by your local code.
UUnnrreegguullaatteedd ccoommbbuussttiioonn
Please observe that combustion air openings and flue
pipes are not reduced in size or closed. Make end user
aware of these guidelines and their potential danger.
Clean the chimney and the flue gas tube at regular
intervals.
Check if the draft inducer is clean and in a good
condition.
Installation Manual AutoPellet Air urnace 17 — 28

14 lue gas system
2. Flue gas temperature
The flue gas temperatures are approximately the same for all AutoPellet Air covered in this manual.
The dewpoint of flue gas with wood pellets (max. 10% water content) is approx. 120° .
It is possible to increase the flue gas temperature to prevent condensation inside the chimney and avoid
damage due to damp. Only authorised installers may increase the flue gas temperature.
Note:
The increase in flue gas temperature results in reduced efficiency and thus increases fuel
consumption.
3. Negative pressure of the chimney
The urnace must be connected to a chimney or a vertical venting system that is capable of handling and
producing a negative breeching pressure of –0.4 “WC. Use a draft gauge to verify the indicated draft va-
lue, adjust barometric damper as required. Drill a small hole in the connection pipe at about 2in/ 50mm
from the urnace flue outlet and use this hole as your measuring point.
himney draft
The suction effect of the chimney draft must extend all the way to the urnace flue pipe connection. The
maximum flow rate that can be drawn through the chimney limits the maximum performance of the chim-
ney connection. The urnace performance must be reduced if the chimney does not possess the necessa-
ry cross-section. This may only be performend by authorised personnel.
4. Power venter
AutoPellet Air are approved by the manufacturer for installation with the ield Con-
trols SWGA power venter which is approved for wood pellet burning appliances.
urnaces installed with SWGA power venters must follow all manufacturer´s instal-
lations and must comply with all applicable codes from agencies having authority
over the installation.
5. leaning
Clean the flue gas tube and chimney regularly. Solid fuel burning appliances need to be cleaned frequent-
ly because soot, creosote, and ash may accumulate. The hotter the fire, the less creosote is deposited.
Cleaning intervals can vary in warm periods due to this and become more frequent.
RRiisskk ooff cchhiimmnneeyy ffiirree
Creosote-formation and need for removal:Low flue gas
temperature can cause creosote. Creosote can conden-
se in a relatively cool chimney. As a result, creosote resi-
due accumulates on the flue lining. If ignited, this
creosote will create an extremely hot fire. The chimney
and the chimney connector should be inspected at least
twice monthly during the heating season to determine if
a creosote buildup has occurred. If creosote has accu-
mulated it should be removed to reduce the risk of a
chimney fire.
OOxxiiddaattiioonn ooff cchhiimmnneeyy
Do not use metal brushes to clean chimneys made of
stainless steel.
Your state and local regulations must be observed.
PE 603 USA_ A 1.0

Safety systems 15
5.5 Safety systems
The following safety measures are the prerequisite for safe operation of your system.
Emergency stop switch
Every heating system must be able to be switched off with an Emergency Stop switch. The
Emergency Stop switch must be outside of the urnace room.
Safety temperature sensor
The pellet urnace is equipped with a safety temperature sensor. This is located on the pel-
let urnace. If the urnace temperature exceeds 230° then the heating system switches
off.
5.6 Installation with an existing Furnace
AutoPellet Air urnaces are not to be connected to a chimney flue serving another appliance. However, when
all State and local codes allow for the sharing of chimney flues, the AutoPellet Air urnaces and another appli-
ance burning pellets or a different fuel can be operated simultaneously while connected to a single existing
chimney or flue gas system providing the following conditions are met:
• All state and local codes permit the specific installation
• All appliances are installed in accordance with the manufacturer’s installation specifications or if lacking
manufacturers specifications, the appliance in question is installed in a manner commonly recognized as
safe and correct for the application and circumstances
• The chimney or flue gas system must be able to handle the combustion products of either appliance and
both appliances when operated simultaneously

The pellet hose and the air hose are flexible spiral hoses made out of plastic. A copper braid avoids the static
loading of the spiral hose.
To avoid damage to the spiral hose, you must observe the following assembly guidelines:
Bending radius The hose should be led as briefly as possible and with a few curves as necessarily. Bend-
ing radius may never be smaller than 12 inch.
Upward
gradients
Max difference in height = 19 feet
Note: A difference in height of up to 10 feet can be overcome at one time. Larger diffe-
rences in height must by interrupted with a 4 foot horizontal run of the pellet hose.
Impact
protection
The spiral hose can be mounted up to 19 feet exactly straight. In such cases however, it is
very important to create a slight "S" in the pellet piping before a sharp curve to slow
down the pellets to prevent hose damage.
Installation in
the soil and
openings:
When installing pellet lines underground remember! The pellet lines are not designed for
direct burial and require protection from being crushed or chewed by varmints.
Protective piping should be minimum 4 inch and sealed at each end. There should be no
bends greater than 15 degrees in the underground sections of the pellet hose.
Tightness To avoid problems with your pellet lines, it is important to have all hose connections se-
cured completely air tight with hose clamps.
Static
neutralization
The hoses are provided with a copper braid, those the hose keeps antistatic. In order to
ensure the function of the anti-statics, those copper braid must be attached at each end
to the existing grounding become.
Fire protection At a wall break-through to the heating room must be installed a fire protection seal in the
pellet- and the air hose.
