This ACR gas appliance is a high efficiency, Balanced Flue Live Fuel Effect appliance. It pro-
vides radiant and convected heat using the latest burner technology. As well as having a var-
iable heat output, these fires also utilise a special control system that allows the appliance
to function in thermostatic and timer modes. A Symax device could be used instead of a
Puck handset and also a smart phone or tablet in conjunction with My Fire app & My Fire
module.
User Instructions
Installation and service must be performed by a qualified installer,
service agency, or the gas supplier. Installation shall conform with
local codes, or in the absence of local codes, in accordance with
the National Fuel Gas Code ANSI Z223.1 /NFPA 54 or the IFGC or
CSA B149.1. All piping and tubing must comply with local codes
andordinances.
Use only your hand to push in or turn the gas control knobs. Never
use tools. If a knob will not push in or turn by hand, do not try to
repair it. Call a qualified service technician. Force or attempted re-
pair can result in a fire or explosion.
Do NOT use a product if you suspect it has been subjected to high
temperatures, damaged, tampered with, or taken apart. Do NOT use
a product if you suspect it has been under water or that liquid has
seeped into the product. Any of these incidents can cause leakage
or other damage that may affect proper operation and cause poten-
tially dangerous combustionproblems.
Do NOT store or use gasoline or other flammable vapours and liquids
in the vicinity of this control or other appliances.
WHAT TO DO IF YOU SMELL GAS
▪Do NOT operate anyappliance.

Before installation, check that the local distribution conditions, nature of the gas and pres-
sure, and adjustment of the appliance are compatible.
This appliance is intended for use on a gas installation with a governed meter.
This gas installation may only be installed by a registered professional competent person
(Gas Safe installer in the UK). The installation must adhere to the requirements of the local
and national Building Regulations and national standards. The installation manual must also
be followed.
Emergency Gas Isolation
In the event of a gas leak or if gas is smelt, the appliance must be isolated. This is done by
turning OFF the gas at the isolation tap. This isolation tap is located at the rear of the appli-
ance.
We strongly recommend a carbon monoxide detector conforming to EN50291 is perma-
nently fixed in the same room as the appliance.
Operating the Appliance for the First Time
Before igniting the appliance, ensure that all packaging, safety stickers and any protective
wrapping have been removed, and that the glass has been cleaned, including all fingerprints
from the glass. If fingerprints are not removed, they will permanently mark the glass.
Ensure that the room is adequately ventilated the first time that the appliance is ignited; we
would recommend opening windows if possible. Run the appliance at full setting for a few
hours so that the paint gets an opportunity to fully cure. Take care not to touch the paint
during this process as this will leave a mark.
During this period, it is possible for some fumes and vapours to be given off. We would rec-
ommend keeping children and pets out of the area at this time.
Do NOT use if leakage is detected. There is a danger of fire or explosion depending on conditions.

General Notes
This appliance may be installed with a roof terminal or a wall terminal.
This appliance may only be used with Balanced Flue (otherwise known as Concentric Flue)
parts as specified by ACR. The ACR specified flue parts have been approved with the appli-
ance. If the appliance is installed on non-ACR approved parts, ACR cannot guarantee or ac-
cept any responsibility for the proper and safe working of the appliance.
The flue system must be constructed from the appliance upwards, with all joints being fully
locked and sealed using the ACR specified parts.
If installing the flue renovation kit, the existing flue must be swept & checked for soundness
prior to installation.
Timber Frame Construction
Whilst it is possible to install room-sealed appliances in timber frame properties, great care
needs to be taken to ensure that the flue assembly does not interfere with the weather
proofing qualities of any outer wall which it may penetrate. Before attempting this work,
further details need to be referenced, (e.g. “Gas Installations in Timber Frame Buildings”
from the GAS SAFE installer publications in the UK).
Car Port or Building Extension
Where a flue terminal is sited within a car port or building extension, it should have at least
two completely open and unobstructed sides. The distance between the lowest part of the
roof and the top of the terminal should be at least 600mm.
Note: A covered passageway should not be treated as a car port. Flues should not be sited in
a covered passageway between properties.
Basements, Lightwells and Retaining Walls
Flue terminals should not be sited within the confines of a basement area, lightwell or
external space formed by a retaining wall, unless steps are taken to ensure the
products of combustion can disperse safely at all times. It may be possible to install this
Balanced Flue system in such a location provided that it is not sited lower than 1m from the
top level of that area to allow combustion products to disperse safely.
Flue terminals should be sited to ensure total clearance of the combustion products in
accordance with the manual.
When the products of combustion are discharged, they should not cause a nuisance to
adjoining or adjacent properties and they should be positioned so that damage cannot occur
to other parts of the building. If the outer wall surface is constructed of combustible
material, a non-combustible plate should be fitted behind the terminal projecting 25mm
beyond the external edges of the terminal

15
Terminal Guards
The flue outlet should be protected with a terminal guard conforming to BS5440-1
if persons could come into contact with it, or if it could be damaged or if it is in a
vulnerable position such as where the flue discharge is within easy reach from the
ground (less than 2m) balcony, veranda or an opening window.
The flue outlet can be either taken from the standard top exit or converted rear exit of
the appliance.
