10 What to do in an emergency

Prerequisites for installing a pellet boiler 11
55 Prerequisites for installing a pellet boiler
You must fulfill the following conditions before operating a fully automatic pellet boiler.
5.1 Guidelines and standards for installing a pellet boiler
Overview of standards and guidelines applying to the installation of a pellet boiler.
Check whether you need to obtain planning permission or approval from the authorities for installing a new
heating system or changing your existing system. Legislation in your country must be observed.
lue gas system EN 13384–1 Legislation in your country must be observed.
Building and fire pre-
vention regulations
Legislation in your country must be observed.
Type of installation C 42x ireplace with a flue gas fan for connection to an air exhaust sys-
tem. The combustion air line from air shaft and the connecting
piece to the chimney are part of the fireplace.
C 52x ireplace with a flue gas for connection to a chimney. The com-
bustion air line from outside and the connecting piece to the
chimney are part of the fireplace.
Sound insulation DIN 4109 Please note the building-unique demands on sound insulation.
5.2 Installation room
The installation room of the boiler is not necessarily a boiler room. Observe the applicable national and regio-
nal regulations.
1. Safety warnings for the installation room
RRiisskk ooff ffiirree
Do not store flammable materials or liquids in the vici-
nity of the pellet boiler.
Do not permit unauthorized persons to enter the boiler
room - Keep children away.
Do not operate with fuel loading or ash removal doors
open.
2. Ventilation of the installation room
The installation room must have air inlet and outlet openings for ventilation, even if there is a direct con-
nection to the burner for combustion air.
This is to keep the combustion zone at a neutral pressure.
3. Admission of combustion air,
the pellet boiler requires combustion air. The combustion air can be supplied by:
a. Relying upon the boiler room air as supplied by the air inlet and outlet openings for ventilation in the
installation room.
b. Independently of the room air via a separate air intake line with a direct connection to the outdoor
atmosphere.
The air intake line must not follow the sewage pipe. The diameter of the air intake line must be at least
4 inches. If the air line is greater than 12 feet in length, or if it has more than 270 degrees of turns, then
it should be increased in size to 5 inch.
Never operate the pellet boiler if the air intake openings are partially or completely closed.
Contaminated combustion air can cause damage to the pellet boiler. Never store or use cleaning deter-
gents containing chlorine, nitrobenzene or halogen in the room where the heating system is installed, if
combustion air is drawn directly from the room. Be particularly cautious around swimming pools and
Operating Manual AutoPellet® PES 20, 32, 56

chemicals.
Do not hang out washing in the boiler room.
Prevent dust from collecting at the combustion air intake to the pellet boiler.
4. System damage due to frost and humidity
The temperature in the installation room must not drop below 38° and must not exceed +86° . The rela-
tive humidity in the installation room must not exceed 70%.
5. Danger for animals
Prevent pets and other small animals getting into the installation room. Install grilles over all openings.
6. Flooding
In the event of a flooding risk, switch off the pellet boiler and disconnect it from the main power supply
before water enters the boiler room. All components that come into contact with water must be replaced
before the pellet boiler is put into operation again.
5.3 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 suffi-
cient draft to safely draw away the flue gas regardless of the status of the boiler. Low flue gas tempera-
tures 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-resistant needs to be rennovated before use. ollow guidelines below:
Boiler size AutoPellet
lue gas tube diameter (at boiler) inch/mm 6/160
lue gas temp. / rated power ° 266 – 320
lue gas temp. / partial load ° 194 – 248
Min. draft – full load/part load in/wc – 0.04 / – 0.02
Chimney 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 hydronic heater is/are responsi-
ble 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:
PE 568 USA 2.0
12 Flue gas system

Flue gas system 13
a. Selkirk sure temp
b. Supervent (JSC)
c. Security chimneys (secure temp ASHT)
Use flue gas pipe from chimney to boiler 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.
2. Flue gas temperature
The flue gas temperatures are approximately the same for all AutoPellet 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 boiler 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 boiler flue outlet and use this hole as your measuring point.
Chimney draft
The suction effect of the chimney draft must extend all the way to the boiler flue pipe connection. The
maximum flow rate that can be drawn through the chimney limits the maximum performance of the chim-
ney connection. The boiler performance must be reduced if the chimney does not possess the necessary
cross-section. This may only be performend by authorised personnel.
4. Cleaning
Clean the flue gas tube and chimney regularly. Solid fuel burning appliances need to be cleaned fre-
quently because soot, creosote, and ash may accumulate. The hotter the fire, the less creosote is depos-
ited. Cleaning intervals can vary in warm periods due to this and become more frequent.
Operating Manual AutoPellet® PES 20, 32, 56

RRiisskk ooff cchhiimmnneeyy ffiirree
Creosote-formation and need for removal:Low flue gas
temperature can cause creosote. Creosote can con-
dense in a relatively cool chimney. As a result, creosote
residue 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 568 USA 2.0
14 Flue gas system

Safety systems 15
5.4 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 location is determined by your local code requirement.
It should remove all electrical power from the boiler.
Safety valve / Over Pressure Relief Valve
This valve opens when the pressure inside the heating system increases to max. 43.5 PSI.
or North America, a 30 PSI Relief Valve is supplied with each boiler. This valve must not be
locked out or plugged and must be within 3 feet of the boiler, with no valves between the
relief valve and boiler.
Low Water Detection
The "Low Water Detection" device is connected to the Emergency Stop of the boiler.
Should a low water condition be detected, the boiler stops firing immediately. This device
must be of the manual reset variety.
Safety temperature sensor
The pellet boiler is equipped with a safety temperature sensor. This is located on the pellet
boiler. If the boiler temperature exceeds 230° , then the heating system switches off.
Expansion tank
All heating systems must be equipped with an expansion tank.
The overall size of the heating system volume will dictate the required expansion tank size.
IInniittiiaall ssttaarrtt--uupp
The initial start-up of each MESys boiler must be per-
formed by an authorized installer.
5.5 Installation with an existing boiler
MESys boilers 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, MESys boilers and another appliance 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.
