Ventilation to the room that houses the fire must meet the requirements of NZS5261.
Ventilation
Prior to installation, timber framing needs to be provided to suit the selected Real Fire. See installation drawing
Framing Details
The minimum hearth size is 300mm into the room and 150mm wider each side than the fire (300mm x
1200mm)
Hearth
A non combustible hearth must be provided in front of the open side of the through wall fire unless the floor is
non combustible.
Hearth – Open side
A non combustible hearth must be provided on the glass side of the Through wall fire unless the floor is non com-
bustible or the fire is raised a minimum of 300mm above floor level.
Hearth – Glass side
The Through wall fire has glass on one side, the other side is open. It must be confirmed which way the fire is to be
installed. The fire can not be reversed after installation. The open side has the higher heat output.
Position of Fire

A suitable gas supply needs to be provided at the right hand side of the timber frame cavity. This is as looking at
the cavity from the side which will be the open side of the fire. See installation drawing. The pipe sizing should be
calculated to supply gas to suit the megajoule rating of the fire. See rating chart. The gas supply should be
reduced down to 10mm copper pipe at the fireplace location and left with a coil of approx 1 metre to feed into the
firebox.
Gas supply
An electrical supply will be required for the fire. This should be by means of a wall switch provided by an electri-
cian, located on the outside of the framing housing the firebox. Not inside the framing cavity. See installation
drawing for preferred location of switch.
Electrical supply
The through wall fire is complete with an insulation kit. The insulation kit allows the fire to be installed with minimal
timber clearances: 10mm minimum from the sides of the firebox, 25mm minimum clearance from the top of the
firebox. Timber clearance from the flue is also 25mm. There is no requirement for any additional fireproof
materials within the fireplace cavity providing minimum clearances are allowed.
Insulation Kit & Timber Clearance
It is important to confirm the height the fire is to be installed above the floor level. This is usually the hearth
height. For example if the hearth is 100mm high then the fire needs to be 100mm high ( note- some elevated
installations specify the fire higher than the hearth) Once the height is confirmed a platform needs to be built to
support the firebox. The platform can be of timber construction. It needs to be sturdy and level.
Height of re from oor
The firebox has a channel around both sides for gib fixing.

The minimum flue height is 2.4 metres. The Through wall fire has two flue outlets. Two separate flues connect to
the flue outlets which are then connected to a Y piece which is a transition to join the two flues into one larger
flue. One flue is then continued through to termination with a cowl outside. The Flue cowl should be no lower
than 900mm vertically from the roof line, and a 2 metre horizontal clearance from any part of the building.
See cowl clearance drawings.
Flue requirements
Firstly the firebox and flue are installed and then the burner is installed. The burner may be installed at a later date
when all the construction work is complete and the hearth is in place. The firebox is placed on the platform pro-
vided and the 10mm gas pipe is pushed through the hole in the firebox. The pipe is to be connected to the burner
but may be left sealed if the burner is to be installed later. Leave enough pipe to connect the burner. When placing
the firebox in the timber cavity it is important to ensure it is centred correctly. Centre the firebox from the front
flange on the firebox. Not from the insulation kit inside the cavity. Once the firebox is in place ensure it is level
and positioned correctly. From the positioned fire the flue can be assembled. The flue is in 1200mm lengths with
both inner and outer flue.

If a timber surround is to be fitted, ensure it complies with Real Fires minimum clearance dimensions.
See installation drawing.
Timber surround
The burner is supplied boxed complete with firebox reflectors, fascia panels, vermiculite, logs & coals. To make the
gas connection, place the burner in the firebox so that it is positioned central and controls drop into cut outs in
base of firebox. The gas pipe should be bent into position and marked for cutting. Remove the burner, cut the pipe
and make a flare connection. Clean the glass panel as required to ensure there are no marks on the inside.
Remove the protective coating from the fascia panel for the glass side of the fire (this is the panel without the
remote control receiver). Fit the fascia panel on the glass side of the fire, the slots in the fascia drop onto the
screws in the sides of the firebox. Ensure that there are no marks on the fascia, it is dicult to clean once the
burner has been installed. Fit the burner in place. Connect the gas supply and test for soundness. The electrical
leads to the burner control and from the burner control to the fan will need to be connected. These are nylon plug
connectors. Line in 3 pin socket connects to 3 pin plug to control box 4 pin plug from control box connects to 4
pin socket to fan. The lead with the small jack plug connects to the remote control receiver board on the stainless
steel fascia panel. Leave this unplugged at this stage.
Installation of Real Fires burner into rebox
Each flue length has a crimped end to join tightly to the next length. Each joint must be securely fixed by at least
three stainless steel rivets. The firebox has two spigots for the two 1200mm x 150/200mm lengths flues to locate
over. The Y piece is then connected, joining the two flues into one. From the Y piece a single 200/ 250mm flue is
used to the termination of the flue. The flue lengths should be installed with the crimped end facing up.
The Firebox and the flue should be secured by fixing with seismic strapping and/or brackets to framing. Flue bends
are available from Real Fires if the flue needs to be oset. Appropriate weatherproof roof flashing/ chimney cap-
ping must be used to comply with NZS 5261. Once the installation of the firebox and flue is complete, the build-
ing work around the fireplace can continue. Ensure any timber fitted around the flue and top of firebox has
a minimum clearance of 25mm. Looking at the fire from the open side there will be an electrical lead for the fan
from the left hand side of the firebox. This is intended to be connected by an electrician to a wall switch facing the
room. See installation drawing. The firebox is also pre wired for and optional electric On/O. This is the lead from
the right hand side of the firebox. If this option is used then this will also require wiring to a wall switch. (Please
ensure the electrical leads are not left behind the firebox and overlooked. It is dicult to gain access once the
giboard is fixed)

The L. P.G. burner is a flat steel burner. This burner is supplied with a bag of coarse grain vermiculite, spread this
thinly (5 to 10mm ) over the surface of the burner. Follow instructions for Log and Coal placement as with Natu-
ral Gas burner.
L.P.G. Burner
Ensure all protective covering is removed from all stainless steel panels before subjecting to heat.
Connect the small jack plug lead to the receiver board on the fascia panel. Leave the fascia panel placed in front
of the fire but not fitted. The mains power supply needs to be connected and turned on. See instructions for
remote control. Press the power on at the remote. The pilot should ignite, it may take several attempts until the
air has been purged out and gas is through. Once the pilot has ignited the burner will light. Check that the flame
travels easily across the burner and that coal placement does not aect ignition. Re - position logs & coals if re-
quired. Ensure that there is no vermiculite touching the pilot, ignition electrode, or flame
sense electrode. This will cause ignition failure.
Commissioning of the Burner
Fill the burner tray with the vermiculite supplied ensuring the burner tube is completely covered. Place the large
logs across each other in the centre of the burner and the twigs and coals around them to cover the burner with
open spacings to allow the radiant heat escape. See drawings of log & coal layout Do not place logs or coals close
to the pilot. See Diagram.
Natural Gas burner
Check the burner from the test point. This is located on the burner supply pipework on Natural Gas models and
on the burner injector on L.P.G.models
Gas pressure
See appliance data badge for pressure settings
Adjust the pressure at the gas valve if required. See valve picture. There are two adjustments, High and low set-
ting. These are located at the front of the valve at the head of the blue solenoid.
High adjustment – This is the outer Brass hexagonal nut
Low Adjustment – This is the inner Red adjustment screw
When adjusting the high setting hold the low adjuster in place otherwise both may turn.

ALL INSTALLATIONS MUST BE CERTIFIED
Fit the Stainless Steel or Black trims to the firebox. The trim brackets are designed to hang over the flange on
each side of the firebox. Each flange has provision to be moved slightly in or out to allow the bracket to fit. The
flanges have a raised square near the base of the fire. The Velcro pad is fixed to this by removing the backing from
one side of the pad and pushing firmly in place. Then remove backing from the other side. Repeat on opposite
side. Hang trim on brackets and check for level then firmly push onto Velcro pads.
Fitting Trim to rebox
Four sided trims are available as an optional extra with the through wall fire. This is for use when one or both sides
of the fire has a hearth lower than the base of the fire. The method of fixing is the same as the standard trim.
Optional four sided Trims
The through wall fire can be installed through an outside wall with the glass on the outside. In these situations a
second glass panel must be ordered and fitted over the existing glass panel at the time of installation. Please note
Real Fires do not supply any weatherproof flashings for the through wall fire.
Optional glass panel for inside/ outside installations.
Once the installation is complete, instruct the user on the operation of the fire and complete commissioning
details in the Real Fires user manual.
Instruct User
Check the re is operating correctly and test for spillage of combustion products.
Fit front fascia panel onto the fixing screws.
Front fascia panel
Fit side reflectors by tilting on an angle locating base onto fascia panels and placing vertical. A retaining clip is
already fixed to the firebox to secure reflector in place.
