8.1
To Start the Heater
1. First ensure that the gas supply to each
heater is turned on by opening the main
gas shut off valve.
2. Switch on the electrical supply to the
heater. The ‘power on’ lamp will illuminate.
3. Ensure that the settings of the thermostat
(single stage thermostat VCLUS, two stage
thermostat VCLUS HL) and any time
switch are set so that the heating system
will be required to operate.
4. The fan will start and the ignition sequence
will commence.
5. Ignition of the burner will occur and the ‘low
fire’ light only will illuminate for low fire and
both the ‘low fire’ and ‘high fire’ lights will
illuminate for high fire.
6. If ignition is unsuccessful the gas valve will
close and the spark ignition de-energize
after approximately 15 seconds. For
approximately 30 seconds the fan will
purge the system then re-ignition will be
attempted. After 3 failed attempts the
control unit will ‘lock-out’, the ‘power on’
lamp will remain illuminated and the fan will
continue to run. To reset after ‘lockout’,
switch off the power supply to the heater
and wait 5 minutes, then turn the power on.
If repeated ‘lockout’ occurs investigate the
cause.
8.2. To Switch Off Heater
To switch off heater, ensure
that
the
settings of the thermostat (single stage
thermostat VCLUS, two stage thermostat
VCLUS HL) and any time switch are set so
that the heating system will be required to
turn off. The burner will stop and fan will
shut off.
8.3. Servicing
To ensure continued, efficient and safe
operation it is recommended that the heater
be serviced regularly by a qualified person
every year in normal working environments,
but in exceptionally dusty or polluted
environments more frequent servicing may
be needed.
Radiant tubular infrared heaters are designed for overhead heating of industrial and commercial
buildings. Individual heating units are suspended from the roof.
