3General information
As require b the United States Departmen of Environmental Protection the following information is given
for the:
Smart XS wood pellet fired central heating boiler. Manufactured b Maine Energ S stems, of 8 Airport
Road, Bethel, Maine, 04217
• The Smart XS has a thermal output levels from 6 kW or 20,500 btu/h to 18 kW or 61,400 btu/h and
complies with EPA 2020 requirements.
• This wood heater has a manufacturer-set minimum low burn rate that must not be altered.
It is against federal regulations to alter this setting or otherwise operate this wood heater in a manner
inconsistent with operating instructions in this manual.
• Complete installation information is found in the Installation Manual.
• Although operational information is elsewhere in this manual, there are specific concerns for correct
operation that can directly affect the emissions profile of this equipment.
It is therefore necessary that we mention these important points.
• uel loading and selection. Yoour Smart XS is equipped with completely automatic fuel loading.
Thus, other than selecting the correct fuel, there are no loading instructions as such. uel selection is
straight forward.
Only P I Premium 100% wood pellets should be used in your boiler.
• Amoung the materials that are specifically prohibited to be burned in your Smart XS are: trash, plastics,
gasoline, rubber, naphtha, household garbage, material treated with petroleum products such as
particleboard, railroad ties, and pressure treated wood.
Burning these materials may result in release of toxic fumes or render the boiler ineffective and cause
smoke.
• Your Smart XS pellet fired boiler is completely automatic ignition as well as the loading as before
mentioned.
There are therefore no starting proceedures to be followed. The boiler correctly starts itself when required
by building load.
• There are no user adjustments required for the air controls on your Smart XS.
• It is important to have your Smart XS boiler serviced by a trained professional who is aware of the
importance to ensure that there are no inlet air restrictions in or around your boiler’s combustion blower.
And that the air passages within your boiler are free of debris, (creosote, ash, etc.)
The flue pipe and chimney are also clean and free of debris / restrictions.
And that the combustion chamber door seal is airtight when the door is closed and secured.
• Ash removal is also completely automatic on your Smart XS boiler. Ashes should be placed in a metal
container with a tight-fitting lid.
The closed container of ashes should be placed on a noncombustible floor or on the ground, away from all
ombustible materials, pending final disposal. The ashes should be retained in the closed container until all
cinders have thoroughly cooled.
When cooled ashes can be disposed of on your lawn, garden or local transfer station.
• Your Smart XS is not a catalytic type burner.
• A person or persons responsible for the operation of a hydronic heater must comply with all applicable
laws or other requirements, such as State laws or regulations as well as local ordinances.
• A person or persons operating a hydronic heater should be aware that they are responsible for operation in
such a manner that does not create a public or private nuisance condition.
The Manufacturer’s distance and stack height recommendations and the requirements in any applicable
laws or other requirements may not aleways be adequate to prevent nuisance conditions due to terrain or
other factors.
• Your Smart XS should be installed with a minimum stack height of 16 feet.
Providing correct draft as given in the Installation manual.
• Draft is the force which moves air from the appliance up through the chimney.
Installation Manual PELLEMATIC® SmartXS

The amount of draft in your chimney depends on the length of the chimney, local geography, nearby
obstructions and other factors.
Too much draft may cause excessive temperatures in the appliance and may damage the catalytic
combustor.
Inadequate draft may cause backpuffing into the room and ‘plugging’ of the chimney Inadequate draft will
cause the appliance to leak smoke into the room through appliance and chimney connector joints an
uncontrollable burn or excessive temperature indicates excessive draft.
• The efficiency of your Smart XS in condensing mode, running at full power is >96%. This is the result of a
laboratory test and was measured using the HHV of the fuel used.
• You should never operate a combustion appliance of any type in your home without there being a properly
installed smoke and CO detector.
Your local fire department ususlly has good advice on placement of these detectors and how many your
home may need for complete coverage.

66 Prerequisites for installing a pellet boiler
The following must be fulfilled before the installation and operation of a fully automatic pellet boiler.
6.1 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.
6.2 Installation room
The installation room of the Pellematic Smart XS is not necessarily a boiler room. Observe the applicable na-
tional and regional regulations.
1. Safet 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 b :
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
chemicals.
Do not hang out washing in the boiler room.
Prevent dust from collecting at the combustion air intake to the pellet boiler.
4. S stem damage due to frost and humidit
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
PE 607 USA_ A 2.1

Flue gas system 15
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.
6.3 Flue gas s stem
The flue gas system consists of the chimney and flue gas tube. The connection between pellet boiler and
chimney is the flue gas tube. The chimney directs the flue gases produced from the pellet boiler into the
atmosphere.
1. Design of the chimne
The dimensions and form of the chimney are critical to proper system function.
The chimney must ensure a sufficient negative draft in all operating states of the boiler for reliable dis-
charge of the flue gases.
Low flue gas temperatures result in the formation of condensation.
Moisture-resistant chimneys of stainless steel or ceramics must therefore be used. Chimneys made from
plastic are fundamentally not permitted for pellet heating systems.
An existing chimney that is not moisture resistant must be modified accordingly. The flue gas tube must
be of stainless steel.
The joints must be oriented correctly and sealed to prevent the escape of condensation.
Installation without barometric control / draft controller is advised.
Chimne diameter 5 inch. And in accordance with chim-
ney calculation method EN 13384–1
Chimne design Moisture tollerant
Note:
Use a draft gauge to verify the indicated draft value. 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.

Installation Manual PELLEMATIC® SmartXS

The condensation temperature of glue gas of wooden pellets (max. 10% water-content) is on average
122° .
4. Chimne draft effect
By reference of a chimney calculation according to EN 13 384-1, the diameter of the chimney has to be
chosen and the system has to be checked for enough chimney draft. If the flue gas line conforms to the
requirements above, the Pellematic Smart XS can also perform in over pressure up to +.02 inches WC, to
overcome the resistance in the flue system.
It is imperative that all connections, from the boiler to atmosphere are completel tight to an leakage.
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 deposited. Cleaning intervals can vary in warm periods due to this
and become more frequent.
OOxxiiddaattiioonn ooff tthhee cchhiimmnneeyy
Do not use metal brushes to clean stainless steel chim-
neys and flue gas tubes.
Observe the applicable national regulations.
5. Cleaning of the s phon / drain catch
Cleaning of the catch in the condensate drain pipe is the last work step. Cleaning of the syphon prevents
clogging of the waste water pipe. Dismantle all the parts of the waste water line, clean and assemble
again.
Information to help interpret the above information:
Temperature Class (T400) are rated for 500 degrees C or 932 degrees .
Pressure Class (N1, N2, P1, P2, H1, H2)
The Pressure Class relates to the product’s suitability and gas tightness when used on positive (P) or ne-
gative (N) draught applications and is further classified as to the degree of leakage allowed with either a 1
or 2, with 1 having the tightest leakage rate.
or most solid fuel applications where the chimney operates under negative draught conditions, an N1
designation would be common. The N1 designation requires the chimney to meet a leakage rate of less
than 2.0 l.s-1.m-2 at a test pressure of 40Pa over the surface area of the chimney system.
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.

Safety systems 17
6.4 Safet s stems
The following safety measures are the prerequisite for safe operation of your system.
Emergenc 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.
Safet 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.
Safet 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.

77 Product description
The description of the product is intended to provide an overview of the components that make up a MESys
pellet heating system, the parts of the pellet boiler and advice on where you can find more information.
7.1 Function description
The PELLEMATIC Smart XS heating system combines water heating and hot water storage.
Pellets are charged either manually or via the suction system from the storage location into the hoipper, and
from there via the backfire safety device to the drop stage.
The burner auger transports the pellets to the burner plate where the heater rod heats them until they ignite.
The ignition is monitored on the basis of the combustion chamber temperature and switches off once the pel-
lets have ignited.
The fuel and combustion air volume are preset and the vacuum in the combustion chamber is controlled by
means of the flue gas fan. After rising up in the flame tube, the combustion gases are passed down through
the heat exchanger and via the flue gastube and the chimney into the atmosphere.
The heat exchanger is cleaned automatically with the cyclically activated cleaning spring in the heat exchan-
ger. The ash collects underneath the burner plate and is transported by the ash auger into the ash bin.
The combustion chamber and heat exchanger are insulated on the outside. The Pellematic Smart XS has ap-
proximately 4 inches of insulation inside the cladding.

7.2.1 Assembl of the vacuum s stem
The pellet hose and the air hose are flexible spiral hoses made out of plastic. A copper braid embedded in the
hose dissapates static charge when properly grounded.
Assembl guidelines
•Bending radius: The hose should be as short as possible and with as few curves as possible. Bending radius
may never be smaller than 12 inches.
•Vertical Lift: Max difference in height = 10 feet. A difference in height of up to 10 feet can be overcome at
one time.
Larger differences in height must by interrupted with a minimum 4 foot flat section of hose for the pellets.
•Impact protection / Velocit Control: The spiral hose can be run no more than 13 feet in a straight line.
Small bends particularly in front of curves reduces the abrasion of the spiral hose by controlling pellet
velocity.
•Installation in the soil and openings: When burying hose in the ground, it must be inside a protective pipe
such as electrical conduit that is 4 inch in diameter. This pipe must be sealed and may not make any arc mo-
re than 15°.
•Hose to be Air Tight: or trouble free operation, the vacuum system must be 100% air tight at all
connections!
All connection points must be secured with a hose clamp.
•Grounding: The hoses are provided with a copper braid which helps the hose dissipate static charge. In or-
der to ensure this function, copper braid must be connected to a known ground point at each end.
