General Information - Warmington TFG 800 Installation And Operating Instructions Manual

Traditional brick built open gas fire & gas burner

Table of Contents

Like the traditional brick back fires of yesteryear, the Warmington Traditional Fire is built with the experience and techniques of the past.

These make a grand statement in the home. However, they can lack in efficiency. The gas version of the traditional fire benefits from the

aesthetic appeal of a brick backed fire, while remaining convenient and simple to use. The gas version is installed with a wood flue kit and

wood based clearances, so that the fire can be retrofitted to a wood fire at a later date without additional expense.

POINTS TO CONSIDER PRIOR TO INSTALLATION

Location of the fire:

Open fires are better located at one end of a room or area, as they project the heat away from their opening.

The Topography of the Land:

The slope and position of the land in relation to the home has a bearing on how the wind will interact with the fire and flue system. Care needs to be

taken to ensure that the flue termination is in the correct position to maximise performance.

The Prevailing Wind.

Care needs to be taken to ensure that the flue termination is in the correct position, as wind gusts that hit the flue and cowl system may overcome

the cowl and draught back down the flue into the home. This can be a combination of down draught and high pressure.

Pressure Differential, Venting & External Air into the Building:

All fires need air to burn and draw correctly. Kitchen fans, air conditioning units, high wind zones, and naturally forming draught spaces can all have

an effect on the pressure differential from inside the building to the outside. A lower pressure in the building may induce a draught down the flue

system and back into the building, causing the fire to smoke or spill into the building. Care needs to be taken at the design and installation stage to

adequately vent the building to ensure that there is always a neutral or positive pressure at the fireplace and a negative pressure at the flue outlet (a

mechanical system can be added to aid this if necessary). This will ensure that the draught in the flue system is always to the outside.

Wind Noise:

You may encounter wind noise in some installations. It is recommended to use an enclosed chase with a chimney pot to help reduce noise. There

will always be some noise from the flue systems of all fireplaces.

"CAITEC" ROOM AIR REPLACEMENT TECHNOLOGY

Fitted in every Warmington traditional fireplace is Warmington's own "Caitec" technology. The Caitec system draws air from an external air

source (outside the room) to ensure that the open fire has a steady supply of pre-heated combustion air. This maximises efficiency while

maintaining a pressure equilibrium in the home, reducing the risk of back draughting.

The following references are used in this document for the Caitec system and venting requirements:

Air enters the cavity (and heat cell if one is used) through external vents in the surrounding structure. Excess air drawn in will cool

the cavity structure.

The external air travels through the Caitec system within the firebox and enters the combustion chamber via two perforated air

bricks (one on each side).

Combusted gases and particulates are exhausted through the flue system.

The excess air supply that entered the cavity (in 1), that has warmed and risen due to natural convection, exits through the vents at

the top of the cavity (or through the liner and out of a venting cone in the case of venting through the flashing).
