e)
Ensure proper electrical rating in the system by checking voltage at ignition module terminals. To avoid system mal-
function, the voltage range must be within 21.6 Volts to 26.4 Volts.
f)
Test-fire the heating system by following the lighting instructions as shown below and on heater.
4. LIGHTING INSTRUCTIONS
a)
Open the isolation valve in the main gas line, and turn gas control knob on the combination gas valve in the heater to the
"ON" position.
b)
Switch on electrical circuit.
c)
The heater should attempt ignition, and ignite within thirty seconds.
d)
If ignition does not occur, turn off electrical power.
5. SHUT DOWN INSTRUCTIONS
a)
For temporary shutdown, turn off the electrical circuit.
b)
For complete shutdown, turn off the electrical circuit and turn gas control knob to the "OFF" position.
6. AIR BORNE PARTICLES
Under certain conditions, heater may discolour due to ambient air borne particle deposits on the outside surface of the delta
chamber. These deposits are normal and in no way affect the operation of the heater or manufacturer's warranties.
7. SERVICING GUIDE
7.1 GENERAL SERVICING
Servicing of heater is essential for continued efficient operation. Servicing should be carried out annually by qualified service
personnel as follows:.
♦
Clean the ceramic tile with compressed air. Avoid directing air stream at gasket material between tile and heater body.
The air pressure must be lower than 20 psig.
♦
Clean the venturi tube with compressed air. The air pressure must be lower than 20 psig.
♦
Clean the reflectors, by opening the access cover near the Venturi, revealing the end of the bottom rod that holds the
front cover securely in place. Extract rod with long nosed pliers and front will unlock and hinge freely on the top rod, to
allow for cleaning access. Don't forget to replace rod and lock cover upon completion of service.
WARNING: If heater backfires during operation, it must be turned off immediately.
Indication of back firing:
♦
Loud ignition noise, followed by distinct hissing sound.
♦
Little or no visible burning on the ceramic tile surface.
♦
Combustion is taking place inside the burner body.
Cause & remedy of back firing:
♦
Improper gas pressure entering the venturi tube:
- check gas pressure, and check orifice for insect and spider webs
- adjust pressure and clean out orifice as required using a soft pipe cleaner.
♦
Breakage of a ceramic tile and or gasketing:
- replace damaged part.
♦
Faulty sealing of the ceramic tile to the burner body, caused by breakdown of gasket material:
- contact Schwank or your Schwank distributor.
