Installation / Service / User Manual BURNERTECH

2 Introduction

2.1 General

Read this manual carefully BEFORE

unpacking the burner. It supplies important

information on installation, use, maintenance

and safety.

The burner must be installed by

competent personnel such as a Gas

safe/ACS registered gas installer in

compliance with ALL regulations in force

and ALL current local Regulations,

including any National or International

Standards that may apply and according

to the manufacturer’s instructions as

detailed in this manual.

Note: The manufacturer cannot be held

liable for injury to people and animals, or

damage to property as a result of improper

installation.

2.2 Unpacking

Carefully remove all the packing material.

Lift the burner out from within the carton and

inspect it for transit damage. You must

report any damage to your supplier

immediately.

If in doubt, DO NOT USE THE EQUIPMENT

and contact your supplier for further advice.

Note: In addition to the Burner Manual the

packaging also contains the Mounting

Gasket, required for correct installation of

the burner.

Note: All packing materials should be stored

or disposed of with care, as they may prove

harmful to children, animals and the

environment.

2.3 Installation

Before connecting the burner, make sure

that the burner rating matches the appliance

requirements and that both gas and

electrical services are adequately rated.

The burners are designed for use on 2nd

and 3rd Family Gases only. (NG & LPG)

The burner must be firmly secured to the

appliance during installation using the

burner mounting gasket supplied.

The burners are of the pre-mixed type and

MUST be installed in a purpose-designed

room with enough ventilation openings

complying with the current local Regulations,

including any National or International

Standards that may apply.

Note:

The burner MUST be connected to an

adequately sized gas supply. The pipe work

must ensure the minimum required dynamic

gas supply pressure is achieved when all

appliances are operating.

The gas supply MUST have an approved

isolation valve adjacent to the burner and

appropriate means of disconnection for

removal of the burner for service and repair.

The electrical supply to the burner MUST

have a suitable electrical isolation switch.

This is required to have a contact separation

of at least 3mm in all poles.

Before commencing cleaning or servicing

operations, first disconnect the equipment

from the mains supply and turn off the gas.

The burner MUST be adequately earthed

and installed as required by the current local

Safety and Electrical Regulations, and any

National or International Standards that

apply.

Installation / Service / User Manual BURNERTECH

2.4 Modification

When parts are replaced during servicing

only original replacement parts supplied

by the Burnertech must be used.

The equipment shall be used exclusively for

the purposes for which it is designed.

Any other use shall be considered improper

and therefore dangerous.

NOTE: The manufacturer cannot be held

liable, by agreement or otherwise,

for damages resulting in improper

installation and use, and failure to comply

with the instructions as detailed in this

manual.

2.5 Burner Operation

DO NOT operate the burners in dusty

environments for long periods of time or

whilst sweeping the boiler plant room.

Dust ingress will cause premature clogging/

blocking of the burner combustion head

leading to reduced heat input and

heightened potential for burner failure.

If there is the chance for dust ingress please

contact Burnertech for advice on the fitment

of a filter.

To ensure the efficient and proper operation

of the equipment, it is essential that

maintenance operations be carried out at

regular intervals by suitably qualified and

competent personnel, according to the

manufacturer’s instructions as detailed in

this manual.

Always ensure that inlet or exhaust grilles

are unobstructed, and filters cleaned

regularly.

The Maximum operating conditions for the

Gas Valve and Electronic Control are 60⁰C

and 90% RH at 40⁰C non-condensing

2.6 Servicing

Burnertech recommends a 12-month service

interval unless operating in a particularly

dirty/ dusty environment.

In case of breakdown and/or defective

operation, turn off the burner gas and

electrical supply.

Warning: DO NOT attempt to repair the

burner head. If the burner is damaged,

please contact Burnertech for advice.

Failure to comply with these requirements

may impair the equipment’s performance

and safety.

2.7 Removal from use

When it is decided to discontinue the use of

the burner, the user shall arrange for

suitably qualified and competent personnel

to carry out the following:

a. Isolate the electricity.

b. Isolate the gas.

c. Fix a warning label in place on the burner

stating that the burner is out of use and

isolated.

Always observe caution with hot burner

components. If any parts become hot during

operation they will remain hot for some time

after the burner has stopped.

In cases where the equipment is transferred

to another user, the original user should

ensure that this manual accompanies the

equipment at all times for future reference.

3.4 Burner operation

3.4.1 Control operation

The microprocessor-based burner controller is made for fan assisted, direct burner ignition

applications. Versions are available for 120 and 230 volts, 50-60 Hz.

The control powers the gas valve and DC-fan. Normal heat demand is given by a 120 or 230 VAC

switch input (depending on the model)

After heat demand and successful ignition, modulation can be controlled by external 0 - 10V or

4 - 20mA signal (50M).

3.4.2 Basic sequence of operation

The Normal Heating mode is started when the High Voltage Heat Demand input is closed. When

ignition is successful, the fan can be controlled in a number of ways depending on parameter

setting:

•0-10 V control, a DC voltage between zero and ten volts can be applied to connector (X3

Pins 8 & 16). At zero volt the fan will run on Minimum Fan speed. At ten volt the fan will run

on Maximum Fan speed.

•4-20 mA control, with an external resistor of 500 Ώ1 % placed between connector (X3

Pins 8 & 16), the fan speed can be controlled with a current in the range of 4 to 20 mA.

At 4 mA the fan will run on Minimum Fan speed. At 20 mA the fan will run at Maximum Fan

Speed.

•On/Off control, when the option On/Off control is selected, the fan speed depends on the

fan Slope control parameter: When slope control is off (parameter set to zero), the fan

speed will immediately go to maximum. Otherwise the fan speed will rise from Ignition Fan

speed to Maximum Fan speed with(value)*50 RPM/sec. Slope control works for both

increasing and decreasing of fan speed.
