effect on the gas fireplace. This may result in nuisance shut down and give an E3 error code on the handheld remote.

IMPORTANT: For the power flue installation, a single Ø120mm hole, covered with a suitable louvre plate, centrally located at the base of the cavity is required.

3.1It is also highly recommended to add some ventilation to the base of masonry cavities in the form of a group of 3 Ø20mm holes to let in fresh air. If this is on an external breastwork then cover with a suitable louvre plate. Cavity ventilation for power flue installations is mandatory for both timber frame and masonry installations.

4.0Cavity Base:

This appliance MUST be supported and installed on a non-combustible and insulating base. This can be in the form of concrete (minimum thickness 20mm) or non-combustible and insulating fiber board such as Micore 160, Promina, Ederpan LD and Supalux, (minimum thickness 10mm). The base must extend over the entire area of the underside of the appliance. The base must also be leveled by, for example, grouting to prevent vibration from possible fan imbalance.

4.1Wall lining materials such as Plaster Board and fire rated Plaster Board are not suitable to use as a cavity floor as they are non insulating.

4.2Products such as Villa Board or Hardi Flex are non combustible but are not insulators so a minimum of 20mm thickness is required if using these materials.

5.0Hearth:

If this fire is being installed at floor level a hearth made from non-combustible material must extend no less that 300mm from the front of the fire. This hearth should be at least as wide as the fire’s outer fascia and no less than 10mm thick. Raised hearths can be any size but must also be constructed from non combustible materials.

5.1The floor in front of this hearth will still get warm so if the floor covering is vinyl, nylon carpet or another heat sensitive material then we recommend extending the hearth to 450mm from the fire.

5.2NOTE: If the hearth is to be covered with tiles or some other veneer then the fire must be installed so that the base of the fire is level with the finished top surface of the hearth.

6.0Raised Installations Up a Wall:

If the fire is being located in such a way that the bottom of the cavity is any more than 100mm up off the ground no hearth is required. Escea recommend that if a heater is being mounted more than 100mm up a blank wall and no hearth is being used, then a four sided

fascia is used (available from your Escea dealer).
6.1 The floor of the cavity still needs to be covered in a non	150
combustible insulating material as per section 4.0 of this
manual.

7.0 Wall Linings: The wall board that lines the outside of this
	300200
opening can be normal dry wall (Plaster Board) and does
not need to be non-combustible providing that it does not
come any closer to the fire than the dimensions shown in
section 2.0. Note: The temperature of the wall lining
directly above the heater does get warm and hence may
discolour paint finishes that are susceptible to temperature
damage or distort vinyl wall coverings. For durability of
finishes and surfaces you should contact the relevant
manufacturer for their specification.
