1. INTRODUCTION

We would like to thank you for purchasing your high efficiency Firebird Bio-Tec wood

gasification boiler. The Bio- Tec wood gasification boiler represents the very latest in

high efficiency wood burning. It has a rated thermal output of 35kW and is produced

in compliance with the EN 303-5 and 304 standards. The widely sized combustion

chamber allows large pieces of wood to be burnt and ensures minimum cleaning and

maintenance

EU legislation governs the manufacture, operation and efficiency of all wood

gasification boilers. The Bio-Tec boiler must be installed, commissioned and serviced

by qualified and experienced installers. It should be noted that it is the responsibility

of the installer/ householder to ensure that the boiler is properly commissioned.

Failure to do so may invalidate the boiler guarantee and any extended warranty.

WARNING!

Firebird cannot accept responsibility for any damage to persons, animals or property

due to error in installation or in the appliance adjustment, or due to improper or

unreasonable use or non observance of the technical instruction enclosed with the

appliance, or due to the intervention of unqualified personnel.

2. HEALTH AND SAFETY

When installing, commissioning or servicing a Firebird Bio-Tec boiler you must

comply with all relevant health and safety regulations and recommendations. Proper

safety and protective clothing should be worn, including hats, boots gloves and

appropriate eye protection.

If no mechanical fall protection

or fall arrest systems are

provided, working without

suitable safety harnesses can

lead to falls from great heights,

thus causing serious or lethal

injuries.

Safety harnesses should

be fixed above the users

where possible. These

harnesses should only be

fixed to structures or

fixing points with

sufficient load- bearing

capacity.

If mechanical fall protection or

fall arrest systems cannot be

installed for technical reasons,

safety harnesses must be worn.

Do not use damaged

ladders.

Only use safety harnesses that

have been tested and certified

by authorised testing bodies.

Ensure that ladders are

put up safely. Observe

the correct leaning angle

(68º-75º).

Ladders not properly secured

against sinking in, sliding or

falling over may lead to

dangerous falls.

Only lean ladders against

secure points.

Contact with live overhead

cables can be lethal.

Wear protective goggles

when drilling.

Wear cut-proof safety gloves

when carrying out installation

work.

Wear a helmet when carrying

out installation work.

Wear safety shoes when

carrying out installation

work.

4. The Importance of Low Wood Moisture:

The moisture content of wood greatly influences it’s calorific value or ‘burning

energy’. The lower the moisture content, the higher the calorific value as the chart

below demonstrates.

Freshly cut timber in our climate has a moisture content of between 40% and 60% so

it’s important to let the timber dry sufficiently. This may take up to two years in some

cases. Hard woods such as Ash, Oak and Beech enable a longer burn time, raising

the temperature quicker.

Firebird sells a wood moisture meter which

measures the woods moisture content. To use

simply insert the two probes into the wood, along

the grain a wait a few seconds for a reading. For

proper combustion performance the wood

moisture content should be around 20%.

5. OPERATING INSTRUCTIONS

This appliance is not intended for use by children, or persons with reduced physical,

sensory or mental capabilities, or lack of experience and knowledge.

5.1 Householder User Guide:

Important! Before starting the fire make sure the lower chamber door is closed.

A. To start the fire.

Step 1.

After switching on the main switch, push

the start button once until it flickers. The

firing mode is now activated.

Step 2.

Place one firelighter on the base of the

upper/main chamber.

Step 3.

Place a bundle of sticks on top of this fire

lighter as shown.

Step 4.

Light the firelighter and allow in to kindle.

Step 5.

Push the start button again to stop the

light from flickering and allow it to stay

constant green.

Page 8

B. Filling or re-filling

Once glowing embers have formed, the

chamber can be filled with larger logs.

Close the door after filling.

You should check the upper chamber

from time to time and refill if necessary.

The fuel warning light will also indicate

when the more wood is required.

C. Maintaining the fire overnight

The ‘glow’ button is engaged if you want

to maintain the fire for up to 12 hours.

Pressing this button ensures that a small

fire is maintained until the chamber is

refilled (i.e. the following morning)

To disengage the function press the

‘glow’ button

D. Stopping the fire

If you want to switch off the boiler, you must wait until the fuel warning light comes

on. Once that happens you can turn off the main power switch.

5.2 Controller Functions

The following is a brief explanation of the main controller buttons and icons labelled

above:

1. The “ON/OFF” switch is used to switch on mains electric power switch.

2. The LED display shows boiler temperatures and other system information

explained in section 5.3

3. The “START” button engages the boiler for use (once the mains power is

switched on (see 1 above)

4. The “P” button is used to view system information and parameters. Pressing this

button for three seconds and the first system information P1 will appear.

5. The “+” button is used to ‘toggle’ through system information and to increase

figures during the setup operation.

6. The “STOP/-“button switches off the boiler if it is held down for 3 seconds

7. “GLOW” button is used to maintain an ember fire for up to 12 hours

8. If the “FUEL” light comes on it means that the boiler is running low on fuel, or that

the boiler has not fired up successfully

9. The “FAN” led indicates that the fan is running

10.The “ERROR” light flickers when a system error has been identified. The relevant

error code number will appear on the LCD screen, which are;

E1. Boiler sensor error

E2. Flue gas sensor error

E3. Error with upper sensor of the first accumulator tank

E4. Error with lower sensor of the last accumulator tank

E5. Error with sensor for the hot water tank

E6. Error with room stat sensor

11. PUMP No. 1 LED – this indicates that the boiler pump (normally the Laddomat) is

running. This pump is used to charge the accumulation tank.

12. PUMP No. 2 LED – indicates that the central heating pump is operating

13. PUMP No. 3 LED – indicates that the domestic hot water pump is running (when

connected)

5.3 Advanced Controller Information

To view key boiler measurements hold down the P button on the controller for more

than 3 seconds. The first measurement number “01” will flash on screen. Use the +

and – buttons to toggle between the seven different measurements described below.

Code Description

P- 01 Boiler temperature

P- 02 Temperature of hot water storage tank (if connected)

P- 03 Measured room temperature (from room thermostat)

P- 05 Upper temp in the first accumulator (outlet)

P- 06 Lower temp. in last accumulator (or 1st accumulator if only one is used)

P- 07 Measured flue gases temp. (in 5 ºC increments)

Set-up Parameters

To view system set-up parameters hold down the P button and the glow button for

more than three seconds. The two red LED’s will begin to flicker. Again use the + and

– buttons to toggle between the different parameters listed below. Please note that

for safety reasons only the first three can be changed by the user – all others are

factory set.
