4. Deviation from Instructions
Consult Jetmaster prior to commencing installation, if any deviation from these guidelines is being
considered. Failure to do so may result in an illegal, dangerous and uninsured installation and
will invalidate your Jetmaster Warranty.
5. Ventilation
Two ventilation openings to the outside must be provided, one at just below ceiling level and
one at floor level. An existing regulation 150cm
2
ventilation opening at ceiling height is
satisfactory, if checked clear. The lower vent can be made quickly and cleanly using a core
drill and fitting a sleeve and air vent at each end. The lower level opening is best placed on
the same wall as the fireplace and as close as possible to the fire. Larger vents are required
when venting to adjacent rooms (300cm
2
).
6. Flue System
The fireplace within which the gas grate is to be placed, must be flued with the model
appropriate diameter flue to the outside, of ideally not less than 3.6 metres height and fitted
with a suitable cowl. The flue system must be swept with a brush before installation and
annually thereafter. Do not install the gas fire and operate in conjunction with a flue pipe of a
lesser diameter than specified for the respective firebox.
7. Preparatory building work for installation in a Jetmaster Universal / IGC built-in or
Jetmaster freestanding fireplace
The normal Jetmaster Universal built-in firebox and / or freestanding fireplace installation
instructions must be carefully followed. On no account should the flue dimensions be
reduced below the recommended minimum.
