2. GENERAL

Fully automatic NG-L gas-fired warm air heater for
stable heating - equipped with infrared flame
monitoring, electrical
blower, and open
operation without an flue gas system.
The unit can be converted to another gas type by
means of nozzle change and pressure adjustment.

3. SAFETY FEATURES

The WAH is equipped with a safety temperature
controller (STC) as a safety feature to prevent
overheating.
The STC shuts down the WAH upon exceeding
the definitively set temperature.
The integrated restart lock prevents restarting the
WAH.
After cooling the WAH, the cause must be
eliminated and the STC must be manually
released. The reset button is located on the
switching unit under the black screw cap
(Pos. 13).
Then press reset button on the side of the
switching unit (Pos. 15).
The built-in infrared flicker sensor serves as a
flame monitoring device and is connected to the
automatic gas firing unit that controls and
monitors the overall function of the WAH.

4. INSTALLATION/ ASSEMBLY

In order to prevent personal injury and
property damage, the relevant local building,
fire-prevention and professional organization
regulations must
observed.
Before setting up it must be ensured that the
local supply conditions (gas type, pressure)
and the current
correspond.
The WAH should be operated only in well-
ventilated spaces and must not be used in
residential or similar premises.
To comply with the MAC limit values at the set-up
location, for each KW of device output a fresh air
exchange rate of at least 25 m

It must be absolutely assured that there is
adequate distance from inflammable objects and
structural parts, especially on the exhaust side
and this must be verified at the time of initial
operation and further start-ups of the equipment.
The top, bottom, side and rear safety margins
must not be less than 1.5 m. On the exhaust
side, it must not be less than 10.0 m.
Caution!!!
WAH electrical and gas hook-ups must be
done only by a specialist and in accordance
with local standards.
Electrical Hook-up:
The electrical hook-up is made using a built-in
power cable with three-wire grounded plug to a
230 V / 50 Hz a.c. power line.
Gas Hook-up:
The WAH is factory – equipped with a G ¾" inside
thread gas hook-up. With NG-L-30 G ½ " inside
thread.
The hook-up to the gas main line must be made
using appropriate connectors.
Since there may be regional differences in gas
composition, proper igniting must be checked on
site at the time of initial operation and further
start-ups.
In the event of imperfect ignition, the position of
the ignition electrode must be adjusted.
These inspections should be repeated at regular
intervals.
Thermostat Connection:
The wiring of a room thermostat or of the floating
contact of a ventilation control can connected to
the existing thermostat plug-box using the
appropriate plug.
