General Instructions and Recommendations 4R.1C
1. A Building consent may be required. Check with your local Territorial Authority before starting any
installation.
2. On completion of the installation – A Producer Statement will be necessary for sign off with the local
Territorial Authority.
3. Brick Chimney checks
Check the structural integrity of the chimney
Sweep the chimney if required (ensure annual sweeps are maintained)
Remove internal brick lean back and side bricks as required
4. Pre install measure checks
Measure width, depth and height of opening to determine the model size to use.
Measure the existing floor protector to ensure it complies. Alter if necessary.
For Gas installations, run the gas line to the fire location (a 15mm dia. hole will need to be drilled into
the side of the installed firebox for the gas line to the burner.)
The height of the opening may need to be increased/decreased to suit. Use a 70mm x 10mm steel bar
lintel for any brickwork above the fire opening.
5. Fitting the Firebox
Remove the damper blade before starting any installation work.
Ensure that any filling and plaster work required in the chimney void is completed (before fitting the
firebox) to ensure a smooth passage for the smoke/gas emissions, is in place. Final plastering/shaping
work will be required once the firebox is fitted into place.
Line the back face and sides of the opening with Rockwool, before sliding the firebox into position.
There must be a tight seal between the firebox and the sides and rear of the chimney using Rockwool.
Always ensure that the bottom of the Jetmaster firebox is sitting at the same level as the floor protector
(hearth), so that the convection air intake is never blocked.
Ensure that 2 x 6mm rawl bolts are used to secure the firebox to the base of the brick fireplace floor
(Earthquake restraints). These are positioned beneath the logpan and at approx ¼ width of the opening
from each side and along the centre line.
Finish off any plastering work through the smoke ports if required.
Replace the damper blade ensuring the smoke ports are not impeded in any way.
It is recommended to fit an appropriate cowl and weather cover to the top of the chimney and plaster it
in place.
6. Finishing work
Any surround or mantle must be installed as per the Fig 6, 7 and 8. Ensure there is at least 100mm
clearance from the fireplace opening to any combustibles. If a cast iron fascia is fitted over the front of
the fire, ensure that rockwool is used to insulate the cast iron from any timber in the surround.

The Fireplace Ltd recommends that allowances are made for air replacement vents to be located near the
fireplace, to aid combustion and reduce the incidence of back venting. Refer to Table 5. for air vent sizing and
suggested location. Fig. 9 - Location points A,B,C,D are suggested combinations. A minimum of one pair of
air vents is recommended or one large vent, as per location point D.
Note: Allowance to be made for minimum 2 x 80mm dia. PVC inlet ducts from outside to internal vent location.
