INTRODUCTION
1. Welcome
Thank you for choosing the NB-Series pellet burning heater. Your pellet heater is designed to provide
the utmost safety, reliability and efficiency. This guide will help you get the best from your heater
and should be retained for future reference.
2. Benefits
Your pellet fire gives you and your family all the benefits of the latest clean-burning technology.
Overseas, pellet heating has become very popular due to environmental and energy issues.
• Energy-efficient. Pellets are burnt at optimum fuel to air ratios. This means that they burn
efficiently (>90%) producing real heat for minimum cost.
• Environmental. Pellet fuel delivers a much cleaner burn than coal or wood and meets the
toughest emission standards in the world when burnt in a specifically designed pellet heaters.
Emission rates of around 0.1 gram are common for pellet heaters which is 25 times cleaner
than the current Australian standard for wood heaters (2.5 grams as at 2015). Pellet heaters
should only emit a small amount of visible smoke during the ignition phase which only lasts
for a few seconds each time the heater is started.
• Healthy. Because pellets burn so cleanly, there is little to no smoke, soot or ash to
contaminate the environment. Silica (sand) and other trace minerals found in the wood that
cannot burn accumulate in the ash pan and can be deposited onto your garden as fertilizer.
• Easy to use. The NB-Series pellet heater makes heating so easy. The fire starts with a push
of the switch or automatically with program and temperature control. No matches or
kindling or lugging heavy and dirty fire wood.
3. Safety
Installation: This appliance and flue system must be installed in accordance with the appropriate
requirements of the Australian Building Code.
• Always make sure that the firepot is ash-free before starting your fire.
• Keep the hopper lid closed unless adding fuel.
• Only use approved wood pellets – DO NOT use any other fuel or accelerants.
• Do not burn waste wood chips, paper, plastic or rubbish.
• Never open the front door after starting the fire.
• The front of heater will get hot, do not touch hot surfaces. Keep children clear and or use a
child safety guard.
• Only clean the heater when it is cold.
• Empty the ash pan before it over fills. Ash and embers must be cool before disposal.
• Never hang cloths too close to any heater.
4. Fuel Requirement
Your pellet heater has been designed to burn wood pellets only. Do not use any other type of fuel
as this will void any warranties stated in this manual.
Quality pellet fuel is a natural product manufactured without any binders or additives. The pellets
are formed under pressure from waste sawdust. There are many variables that will affect the
composition of the pellet fuel and the specifications. The performance of your pellet heater is greatly
affected by the type and quality of wood pellets being burned. As the heat output of various quality
wood pellets differs, so will the performance and heat output of the pellet heater. We recommend
the use of pellets that meet or exceed these standards. Please use a recommended pellet type.

CAUTION:
It is important to select and use only pellets that are dry and free of dirt or any impurities such as high
salt content. Dirty fuel will adversely affect the operation and performance of the unit and will void
the warranty. Do not use pellets if they have become damp and appear swollen from moisture.
Store pellets in a dry environment.
ASH: The ash content of the fuel and operation of your heater will directly determine the frequency
of cleaning. The use of high ash fuels may result in the heater needing to be cleaned daily. A low ash
fuel may allow longer intervals between cleaning.
CLINKERING: clinkers are silica (sand) or other impurities in the fuel that will form a hard mass during
the burning process. This hard mass will block the air flow through the Burn Pot and affect the
performance of the heater. Any fuel, even approved types, may tend to clinker. Check the Burn-Pot
daily to ensure that the holes are not blocked with clinkers and remove as necessary.
If they become blocked, remove the burn pot (when the unit is cold) and clean/scrape the clinkers out.
Clean the holes with a small pointed object if required. Refer to the section Routine Cleaning and
Maintenance.
Pellets made from Harwood present less clinkering than those made from softwood species. This
does not make one pellet better than another, just different cleaning requirements.
PELLET FEED RATES: Due to different fuel densities and sizes, pellet feed rates may vary. This may
require an adjustment to combustion fan’s speed or to the auger feed trim setting on low (contact
PFTAS).

6. Pellet fuel consumption
a. Introduction
Modern pellet heaters have automatic feed control with fixed feed rate settings. This makes
the heater easy to use but does take away our ability to fine tune the pellet feed rate to
account for pellet fuel length differences that may occur.
b. Wood Pellet Length
From season to season, batch to batch or brand to brand, it's very likely that the pellets you
buy could be shorter or longer in length on average. This is very normal. There are several
variables that determine the length of a pellet during manufacturing and any one of them
could be different from brand to brand or season to season.
How does this effect burn? Longer pellets will feed less fuel into the fire with the rotations
of the auger than shorter pellets. If everything else in the pellet heater stays the same, and
the only difference in the fuel is pellet length, shorter pellets will provide more fuel to the fire
than longer pellets resulting in more heat output. Longer pellets will provide less fuel and
therefore produce less heat for the same setting.
c. Consumption Specifications
The fuel consumption rate for Pellet Heaters is usually stated as a minimum and a maximum.
These limits are based on an average. A heater may claim a minimum of 600 grams per hour
on low and 1.8 kgs on high. In reality these feed rates may be more or less depending on the
pellet length. Pellet heaters are designed to be reliable and not go out on the lowest setting.
If the minimum feed rate was set too low the heater could go out un-expectantly if the pellet
length was longer than the average.
d. Heat Output
The heat produced is directly related to the amount of fuel consumed. The faster fuel is
consumed the hotter the fire and the warmer your house will be. Conversely, less fuel, less
heat and lower cost to operate. Due to the ease of starting and stopping a modern pellet
heater, it is more economical to turn the heater off when in bed or when the house is
unoccupied.
e. Feed settings
The power settings P1 and P4 have been programed to provide as close as possible to the
rated specifications of the heater while using typical (normal) sized pellets. If you find that the
average pellet size is smaller than normal, select P2 or P3 as these setting has been programed
to feed less fuel.
f. Conclusion
Using the correct heat setting and or thermostat setting will maintain your desired comfort
level by replacing the heat being lost by your home. If you are unable to reach the desired
comfort level on the highest heat setting then you will require additional heating or reduce
the heat being lost (better insulation, reduce draughts etc). If your home is too hot on the
lowest setting (ECO) then turn the heater off manually or contact Pellet Fires Tasmania
Customer Service for more information and assistance.

Pellet Fires Tasmania – V02.02-18/7 6 www.pftas.com.au
7. Mechanical
The heater is mainly made up of following
items - 1. Combustion burn pot 2. Exhaust fan
3. Room circulation fan and auger motor.
The following is a list of main components and
their functions:
IGNITER
The HEATER comes equipped with an
automatic electric igniter for lighting the fuel
when the heater is in lighting mode only. The
igniter remains energized for the first eight
minutes of the lighting sequence.
VACCUM SWITCH
The HEATER has a safety vacuum switch
located behind the left door, fastened to the
base. If a low pressure is created in the firebox
by a leak, opening the front door, a blocked flue,
or unsealed ash drawer, the vacuum switch will
sense it and cause the heater to go into a
shutdown mode.
AUGER AND AUGER MOTOR
The 2 RPM auger motor turns the auger lifting
pellets up the auger tube. The pellets are then
dropped down a tube and into the firepot. The
auger is controlled by the control board.
OVER TEMPERATURE THERMOSTAT
This safety switch is installed on the bottom of hopper and will shut off the heater if it senses excessive
temperatures (70 degrees).
CONVECTION BLOWER THERMOSTAT
This switch is installed on the vent pipe and turns the convection blower on when the heater is above
40 degrees.
ROOM THERMOSTAT
Measures room temperature and adjusts the heat output. Will switch between ECO (low) and what
ever power setting is chosen (P1 … P4).

4. Setup Instructions - Explained
To enter the setup mode, press and hold the Spanner button DOWN until you hear a beep.
Please refer to the Setup reference guide for the correct button sequence; the following is an
explanation of each feature.
*Warning* Incorrect settings could result in poor performance and or operating failure. Please
contact Pellet Fires Tasmania for advice if required.
a) User control of the Combustion Fan (Smoke fan) and Room Fan speeds
Individual fan speeds can be set for each of the four power settings (P1-P4). Each power level has
settings of plus or minus 20% for each of fan ((S)moke fan and Room (F)an.
Normally the heater would be set to P1 and ECO2 which means that when the room temperature is
lower than what is set on the thermostat, the heater will run in Stabilization Mode using the P1 feed
rate, Combustion fan and room Fan settings. When the thermostat temperature is met, the heater
will run in ECO2 mode which is the P4 setting.
The Combustion fan (Smoke fan) controls the amount of air that is drawn through the burn pot.
• If the amount of air on P4 is too high, the pellet fuel will burn away too quickly, and you risk
the possibility of the fire going out.
• If the amount of air is too low, then you will see poor combustion characterized by a lazy flame.
The glass will go black faster than normal and the heater will require more cleaning. Pellets
could also build up in the burn pot.
• Adjust the Combustion fan to achieve a bright flame without black sooty tips and without
pellets being blown out of the burn pot.
The Room (F)and should be adjusted to provide sufficient convection air flow.
• The higher the air volume the louder the fan becomes but better air circulation is achieved.
• Too low a fan setting will result in poor heat circulation and the possibility of the heater over
heating and automatically shutting down.
b) Cleaning
The heater automatically cleans ash from the burn pot on a regular basis by reducing the fire to a very
low burn and then introducing a brief blast of air. You can choose how often you want the cleaning
process to occur and for how long it should take. The default settings should be adequate for the
type of pellet fuel available and need not be changed.
c) ECO Mode
When selected, the ECO1 option turns the heater OFF when the room temperature is above the
thermostat setting. ECO1 is NOT recommended for Tasmanian conditions and homes. The ECO2
option reduces the power (heat output) level to the lowest power setting (P4). This is like an
overnight burn setting and is the recommended option for medium and larger areas because it does
not cause the heater to go through the startup and shutdown sequences.
d) Language
Select the language of choice. Default is English.
Pellet Heater User Manual - NB-Series
Pellet Fires Tasmania – V02.02-18/7 14 www.pftas.com.au
e) Setting the program schedule
Each hour of each day of the week can be set to be ON or OFF allowing simple or complex schedules
to be programmed which operate when the Auto setting is activated. EG - Automatically turn ON
and stay on between 6am and 8am then again from 4pm to 10pm Monday to Friday and OFF
Saturday and Sunday so that MANUAL operation is used as required on those days.
f) Setting the clock
The hour, minuets, day, month and year can be set to local time. Please adjust as required for day
light savings time.
g) Restore defaults
Select NO to use the changes you have just made or select YES to return to the previous defaults.
h) Display Version
The Firmware and Software versions are displayed for the Controller and Display modules.
i) Exit setup
Press the spanner button at any time to exit the setup programming mode.

Pellet Heater User Manual - NB-Series
Pellet Fires Tasmania – V02.02-18/7 16 www.pftas.com.au
2. Maintenance
Before carrying out any maintenance take the following precautions:
• Make sure that the fire has been turned off, and that the power supply has been disconnected
(Ensure that the plug is disconnected from the socket, thus avoiding accidental electric shocks).
• Make sure that all parts of the pellet heater are cold.
• Make sure that the ashes have cooled completely.
• Always use appropriate tools for maintenance.
• When you have finished re-install all safety guards before using the pellet heater again.
The pellet heater requires little maintenance if quality wood pellets are used which is why we
recommend pellet fuel that is manufactured to the AS/NZS4014.6.
a) Cleaning the surfaces
To clean the surfaces on the painted metal parts, use a damp cloth.
Important: the use of aggressive detergents or abrasive cleaners can damage the surfaces of the
stove. Do not clean with paint thinners or solvents.
b) Cleaning the fire pot before and after each lighting
You must check that the fire pot before and after each lighting. Ensure it is clean and that
no waste or residue blocks the holes, in order to always guarantee excellent combustion of the
stove. This will help avoid possible overheating, which could cause changes in the colour of
the paint, as well as failure to light the stove.
Only a clean fire pot can guarantee that the pellet stove will function without problems. During
operation, deposits may be formed, which have to be immediately eliminated. It is easy to see
when the fire pot has to be cleaned! It only needs a glimpse, each day, before switching on. For
minor cleaning, it can be left in the stove, but if the residue is difficult to remove, it has to be
extracted from its housing and the waste scraped out.
The residue of ash depends on the quality of pellets used. Important: even with a new batch of
pellets, although using the same brand, there may be differences during combustion and therefore
they may burn more or less cleanly.
Correct daily cleaning will allow the pellet heater to burn properly with high performance avoiding
problems in the long term which could require the intervention of a technician to repair the pellet
heater.

c) Cleaning the combustion chamber
The fire requires simple but frequent cleaning to guarantee correct functioning. Therefore,
clean the combustion chamber frequently by using a drum-type vacuum cleaner, making sure
that the ashes are cold first.
d) Cleaning the flue
The flue will require cleaning only once each season providing the correct fuel is used. You
should arrange for this when booking your annual service.
