	Chimney liner A rigid or flexible pipe fitted inside a chimney to form a flue.
	Chimney plate A plate or label fixed inside the fireplace opening giving details of the chimney or flue installation.
	Class 1 Flue A chimney suitable for use with a solid fuel fire.
	Class 2 Flue A metal flue designed primarily for use with gas fires.
	Commissioning Initial start up of installation to check for safe and reliable operation.
	Convector Gas Fire A gas fire designed so that the heat output is enhanced by heated convected air being circulated around the room.
	Conventional Flue A chimney that is dependant upon natural drafts for its operation.

D
	Data plate Plate fitted to appliance to give manufacturers settings and identification details. (Must not be removed)
	Decorative Fuel Effect fires (DFE) A gas fire designed to be installed in an open flue and to simulate a solid fuel fire.
	Detached Valve A control valve that can be mounted up to 1 metre from the appliance.

E
	Efficiency Please refer to the page Gas Fire Efficiencies in our Technical Section for an explanation.
	Embaflame A highly realistic log and ember gas fuel-bed.

F
	Fan-flued system Flue system in which a fan is used to create the draught to remove the flue products.
	Fascia External decorative fireplace frame commonly used in hole-in-the-wall installations.
	Fire-bed The area above a gas burner where the gas burns.
	Firebox A steel box for installation into a fireplace opening designed to accept a gas fire.
	Firebox Fascia A trim and fire front combined into a single unit.
	Fireguard A metal meshed frame place in front of a fire to provent accidental contact and used especially to protect children and elderly persons.
	Flue See Chimney
	Flue box Substitute for a builders opening or fireplace recess made from a non-combustible material.
	Freedom Surround A stylish frame designed to reduce heat damage to the surrounding surface.
	Fuel effect The simulated coal, log, pebble or other fuel of a fire

G
	Gas input The amount of gas used by an appliance usually quoted in Kilowatts per hour on maximum setting.

H
	Hearth The floor of a fireplace that extends into the room.
	Heat Output The typical maximum heat output of an appliance usually quoted in Kilowatts per hour.

I
	Inset Fire An appliance that fits into a fireplace opening, no part of which projects forward of the vertical plane of the chimney breast.
	Inset Live Fuel Effect (I.L.F.E) A gas fire designed to be installed into an open flue. This type of appliance has been designed and tested to meet a higher efficiency standard giving a greater heat output and economical running cost. In certain circumstances, an I.L.F.E appliance may be relied upon as the main source of heat to the room it has been installed in to.

L
	Lint arrester Metallic mesh designed to trap dust, fluff and fibres which would otherwise collect in the airways of the pilot assembly.
	Low Lintel A fireplace lintel (supporting beam) at a low level.
	LPG (Liquid Propane gas) Propane gas sold in bottles. Used in areas where Natural Gas cannot be supplied. (Must be Propane not Butane)

N
	Nett Efficiency Please refer to the page Gas Fire Efficiencies in our Technical Section for an explanation.
	NG (Natural Gas) Gas fed to your home from mains gas pipes.
	No Vent A fire that would normally operate without additional purpose provided ventilation

O
	Optimum Control A wall switch control for operating the fire.
	Oxygen Depletion Sensor (ODS) A safety device that is part of the pilot assembly that extinguishes the fire if there is a build up of harmful gases.
	Oxysure pilot Pilot with a built in safety device which shuts off the gas supply before there is a build up of a dangerous quantity of products of combustion in the room concerned.

P
	Permanent Pilot A pilot that is left on continuously, removing the need to turn it on each time the appliance is lit.
	Physical Barrier This is to provide at least the equivalent level of warning to the approach of an open fire to that of a hearth. It should define a clear zone where occupants must exercise additional caution. This barrier should be made of non-combustible material and be permanently fixed in place.
	Piezo A means of generating a spark to ignite a pilot.
	Pilot A small jet of gas that is used to ignite a main gas burner.
	Power Flued Fire A combined gas fire and flue system for use without a normal chimney. The flue system is operated by an electrically powered fan.
	Pre-Cast Flue A concrete block flue designed primarily for use with gas fires.

R
	Radiant Gas Fire A gas fire designed so that the heat output is produced primarily by infra-red radiation.
	Rear Vent A flue for a power flue fire whereby the flue exits from the rear of the fire, directly throught the wall to outside air.
	Recessed Rear Vent A terminal for a power flue vent fire that is recessed into the outside wall.
	Ridge Vent A raised roof tile that serves as a flue outlet, usually located at the highest point.
	Running Costs The costs of operating an appliance usually quoted on maximum setting in pence per hour.

S
	SAP SAP is the Government's Standard Assessment Procedure for Energy Rating of Dwellings. Methodology for calculation of the energy performance of buildings.
	Side Vent A flue system for a power flue fire whereby the flue can be routed up to 7 metres horizontally to outside air.

	Surface Mounted Rear Vent A terminal for a power flue rear vent fire that is surface mounted onto the outside wall.

T
	Terminal The end of a flue.
	Terminal Guard A guard fitted over a terminal to prevent accidental contact especially with hot surfaces.
	Thermobox A ceramic lined firebox designed to increase the radiant heat output of a gas fire.
	Trim A decorative metal frame around an appliance used in conjunction wih a fire front.
	Trim Switch A high level control for operating the fire located on the fire frame.

V
	Ventilation Provision of a means of air supply to a room from outside air to assist the combustion process.
