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 (>85%) 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 40 times cleaner

than the current Australian standard for wood heaters (4 grams as at February 2012). 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 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

Pellet Heater Owner's Manual - NB-Series

Pellet Fires Tasmania - V8.01 www.pftas.com.au Page 4

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.

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.

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 speciies.

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).

5. Specifications

The Pellet heater is an advanced design and has individual fresh air input and exhaust venting systems.

Negative pressure burning technology causes high efficiency and little ash output during burning.

High output, quick heating and low fuel costs are its advantages.

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.

Pellet Heater Owner's Manual - NB-Series

Pellet Fires Tasmania - V8.01 www.pftas.com.au Page 6

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 setting P1 has 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 Heater Owner's Manual - NB-Series

Pellet Fires Tasmania - V8.01 www.pftas.com.au Page 7

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.
