630292_0_ AUS NZ Installation Manual

Note:

THERE ARE A FEW THINGS TO CONSIDER BEFORE INSTALLATION

•Cavity Dimensions and Clearances

•MUST be installed a 100mm minimum off the floor or nearest horizontal surface.

•Coupling of flue to fire

•Coupling of gas lines to fire

•Fixing the fire to cavity

•Electrical mains socket at rear left corner of the cavity, to accommodate the power

transformer

•Isolation switch for electrical transformer.

•Gas pipe placement to the front left of the cavity.

•The ST900 electronic control system is designed to work within the temperature range

of 0°C to 80°C without batteries and 0°C to 60°C with batteries, with a humidity level that is

non condensing. This is to ensure safe operation of the electronic and gas control system.

•If the fireplace is subjected to an environment with temperatures very close to or exceeding

these temperature limits (irrespective of if the fireplace is on or off at the time) the fireplace

may not start up until the temperature returns back to within the operating range.

•To remedy this, the environmental temperature should be addressed and the fireplace

control system given time to adjust accordingly. The fireplace should then function correctly.

•It would be prudent to consider these operational limits during the installation planning

stage. Protecting the installed fireplace from low external ambient temperatures and cold

drafts through the use of approved modern building methods and materials will help ensure

that the required operating environment is maintained.

•This fire is not intended as an insert (it must be flued in accordance with flue instructions

see section 12).

installation of the fascia panels until the very end of the installation and

commissioning to avoid damage to the fascia panels.

Builder

1. Construct Frame (Section 1.0 to 6.0)

Gasfitter

5. Install Flue + Flue Restrictor if required (Section 13.0)

6. Test fire and verify flame pattern is acceptable

7. Cover-up fire using packaging (Section 16.0)

Electrician

2. Install Electrical connection (Section 15.0)

Gasfitter

3. Install Gas Pipe (Section 7.0 to 8.0)

1.0 Product Description:

The Escea ST900 decorative gas fire

is designed to be built into a cavity.

The appliance is flued via Simpson

Duravent Direct Vent Pro 5”x8” Flue,

available from your Escea distributor

or retailer. The user will control their

fire with the Radio Frequency (RF)

remote.

2.0 Creating the Cavity:

The cavity specifications vary depending on fascia type. The dimensioned drawings in the

following sections show the size of opening that must be created to fit the ST900. The wall

directly above the fire should be finished / gibbed / lined after the fire has been installed,

unless there is an access hatch or the chase is open to the ceiling cavity, which allows the

flue to be installed after the wall has been lined.

The wall and framework in front of the flue must not exceed 100mm in thickness, this

includes plaster board or any wall linings. This is to ensure there is at least 25mm gap

between all fluing components and any combustible material.

2.1 Cavity for Ferro / Molaris Fascias

Note: It is not necessary to line the cavity,

and it may be constructed with timber.

Continue on to section 2.4

2.2 Cavity for Velo Fascias

Note: It is not necessary to line the cavity,

and it may be constructed with timber.

Continue on to section 2.4

2.4 Considerations for creating the cavity:

If installing the ST900 into a purpose built chimney breast or

chase which is not open to the roof space of the building, it

may be appropriate during the planning stage to consider the

installation of additional vents.

Heat otherwise lost through the outer skin of the fireplace and

flue system into the cavity of the chimney breast or chase

may be recovered into the room by placing two air vents in

the cavity or chase. By placing one vent at or just above floor

level and the other near the ceiling of the room will induce

natural convection and prevent heat build up in the cavity and

subsequently recover some of the heat into the room.

3.0 Hearth and Floor Clearances:

There should be at least 100mm between the bottom of the ST900 fire and any horizontal

surface below, for example hearths and floors.

3.1 Wall and Cabinet Clearances:

There must be a minimum of 100mm from the sides of the fascia to any protruding side

walls or cabinetry.

For Velo fascias, the fireplace should be recessed 12mm into the cavity.

4.0 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 fire does get warm and hence may discolour paint

finishes that are susceptible to temperature damage or distort vinyl wall coverings.

5.0 Television Positioning Considerations:

It is becoming common practice for consumers to mount flat screen TV’s above their gas

fireplace.

Most TV manufacturers have specified in their instructions that the TV should not be

installed on, near or above a heat source. For this reason TV location decisions rest solely

with the householder and Escea will not be held liable for any adverse affects on a TV

located near to an Escea fireplace that may be caused by heat.

The drawings below are suggestions that may be used as a GUIDE for those consumers

who do decide to locate their TV above an ST900 gas fire. These drawings show ways to

reduce the amount of warm air rising off the fireplace and onto the TV.

The material that the wall and mantle are made from will also affect the operating

temperature of the TV so it is the customers responsibility to satisfy themselves that their

TV mounting and mantle design will not exceed the listed maximum operating temperature

of their electronic goods.

630292_0_ AUS NZ Installation Manual

5.1 Combustible Mantle Clearances:

The diagram to the right shows the minimum and

maximum allowable size for mantles or protruding

surfaces mounted above the ST900.

Note: Escea does not recommend placement of

items on the mantles shown in the diagram to the

right. This is because of the potential for items placed on

or above the mantle to be affected by the heat rising from

the appliance.

5.2 Non-Combustible Mantle Clearances:

If the entire installation (mantle, wall and cavity) is

constructed from non-combustible materials, the

clearances to mantles may be as shown in the shaded

area.

6.0 Corner Installations:

If a cavity is to be created in a corner,

the following table gives the minimum

7.0 Laying Gas Pipe:

Gas pipe should be sized as per the requirements of AS/NZS 5601. The pipe sizing must

be sufficient to deliver the following volume of gas to the fire with all other gas appliances in

the home running at the same time;

NG = 18Mj/hr

Propane/ULPG = 21Mj/hr
