OPERATING
How the air heater works:
Gas is burned by an atmospheric burner which fires
into a heat exchanger. The gas burner is controlled by
a double gas valve via an electronic burner control,
which is actuated automatically via external controls
i.e. a room thermostat and/or a time switch. The
burner is ignited by a spark igniter. When the burner
fires and warms the heat exchanger, the heat is
sensed by a thermally actuated fan control which
switches on the fan (in case there is no constant
running fan) when the air temperature has reached its
preset operating level.
At the end of a heating cycle the burner is switched
off, the air circulation fan will continue to run until the
air heater has cooled to a safe condition. Thereafter
the fan will remain off until the next cycle is initiated.
Safety:
1. Flame failure is detected by the ionization probe
which is the sensor and will immediately result in
gas valve shut down.
2. Safety against overheating is assured by two
overheat controls. The first is an automatic recycle
control which protects against low air flow i.e.
clogged air ways, fan failure etc. The second,
which is set to a higher level than the first one, is
a control which locks out and switches off the
burner in the event of gross overheating for any
reason. Manual intervention is necessary to reset
this control device. Resetting of the automatic
burner control may also be required.
To light the heater:
1. Turn on the gas supply to the air heater.
2. Switch on the electricity supply to the air heater.
3. Ensure time switch (if fitted) is set to a 'ON' cycle.
4. Adjust control/room thermostat to desired
temperature.
5. Air heater will light automatically when the room
thermostat calls for heat after +/- 30 sec.
6. If the appliance does not light:
a)
check that the burner control does not require
resetting. An indicator light glows at the back
panel of the appliance and on a remote control if
fitted. Reset by pushing reset/button on appliance
or the remote control.
b)
check if thermal overheat control requires
resetting
7 If the thermal overheat control requires resetting
and doing so restarts the air heater, wait until the
appliance warms to thermal equilibrium, to ensure
the overheat control does not lock out again.
If it
does and the return air temperature near the heater
is less than 30°C, then switch off the appliance
and call for service.
If the return air temperature is
over 30°C, take appropriate action to reduce the
ambient temperature near the air heater.
Air circulation:
The space heating process is for air to be circulated
through the appliance whereby it gains heat from a
heat exchanger. The air is directly discharged into the
space to be heated. The air is eventually recirculated.
Therefore it is very important that an unobstructed
path for the circulation of the air will be maintained.
Maintenance:
1. Maintenance and service must only be carried out
by appropriately qualified persons e.g. "Corgi"
registered undertakings.
2. It is in your interest to ensure proper service and
maintenance is carried out at a regular basis.
Periods between service are dependent upon the
local environment where the heater is installed. All
gas appliances should be serviced at least once a
year.
3. In case of any damage to the appliance, it must be
shut down completely and checked by an
appropriately qualified person.
4. In the event of difficulties in resolving any of these
matters, please do not hesitate to contact Reznor
or their official distributor.
NEVER SWITCH OFF ELECTRICTY SUPPLY TO THE
AIR HEATER WITHOUT FIRST CLOSING THE GAS
TAP
