General product information
PHOTON is the latest generation of gas
fired unit heaters, CE and UKCA certified to
EN17082 for use in non domestic installations.
All models and sizes are available for use with
natural gas (G20, G25 or G25.3). The type of
gas, the input rate and the electrical supply
requirement is shown on the heater rating
plate. Check the rating plate to determine
if the heater is appropriate for the intended
installation.
This installation manual is shipped with the

the model being installed. If the manual is
incorrect for the heater, contact the supplier
before beginning installation.
The instructions in this manual apply only to
the models listed.
Installation should be carried out by a
suitably qualified installer in accordance with
these instructions and the current rules and
regulations in force. The installer is responsible
for the safe installation of the heater.
Using this manual
The symbols for ‘Caution’ and ‘Warning’ are
used to highlight certain points throughout
this manual.
Caution is used when failure
to follow or implement the
instruction(s) can lead to
premature failure or damage to
the heater or its component parts.
Warning is used when failure
to heed or implement the
instruction(s) can lead to not only
component damage, but also to a
hazardous situation being created
where there is a risk of personal
injury.
Warranty
This equipment comes as standard with a
manufacturers two year warranty (2 years
parts, 1 year labour) unless agreed otherwise
at the time of order. The warranty is void if:
1. The installation is not in accordance with
these instructions.
2. Wiring is not in accordance with the
diagram furnished with the heater.
3. The unit is installed without proper
clearances wherever clearances are
required regardless of the material being
combustible.
4. The unit is installed without proper
ventilation and air for combustion.
5. The equipment is used in atmospheres
containing flammable vapours or
chlorinated or halogenated hydrocarbons
or any contaminant (silicon, aluminium
oxide, etc.).
6. The unit has not been serviced and
maintained in accordance with the
information contained within these
instructions.
7. An appliance is connected to a duct system
or the air delivery system is modified in any
way.
Ignoring the warning and caution
notices and the advice from the
manufacturer on installation,
commissioning, servicing or use,
will jeopardise any applicable
warranty. This could also
compromise the safe and efficient
running of the appliance itself and
thereby constitute a hazard.
The electrical isolator should only
be used for maintenance purposes
or in an emergency. It should
not be used for closing down the
main burner as it switches off the
fan prematurely and may damage
the heat exchanger, invalidating
the warranty.
