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. 
 
3.1 
It 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.

Cavity 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. 
4.1 
Wall 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.  
4.2 
Products 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.  
 
5.0 
Hearth: 
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. 
 
5.1 
The 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. 
5.2 
NOTE: 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. 
 
6.0 
Raised 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 
combustible insulating material as per section 4.0 of this 
manual. 
 
7.0 
Wall Linings:  The wall board that lines the outside of this 
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.
