TROUBLESHOOTING

1. Ensure that the fuel matches that listed on the nameplate.
2. Ensure that the voltage matches that listed on the
nameplate.
3. Check for any physical damage. All signs of physical
damage to the catalyst pad such as holes, tears or a
general deterioration of the catalyst bed indicate that it is
time to have the heater repaired. Excessive vibration may
cause damage to the inner catalysts structure which may
cause premature failure.
4. Check the gas supply pressure at the heater – 7" w.c.
(1.73 kPa), 4.5" w.c. (1.12 kPa) or 3.5" w.c. (0.86 kPa) for natural
gas and 11" w.c. (2.72 kPa) for propane.
5. Check the gas orifice for obstructions or dirt and ensure
the size matches that listed on the nameplate. It may
be necessary to install a filter upstream of the heater or
regulator if the gas supply is dirty. If the fuel supply is
constantly dirty and/or wet it would be advisable to use
bottled propane fuel.
6. Check the mounting position of the heater. The face of the
heater should be preferably in the vertical position and
should not vary more than 45° from the vertical position for
maximum efficiency.
7. Check for saturation of the catalyst face caused by
condensation or rain running down the face of the heater.
If the heater has been exposed to water, it is advisable to
place the unit in a warm area for a period of a few hours
or longer if required. Once the moisture is removed, the
heater can be re-installed and re-started.
8. Check the start-up leads cable size to ensure that the
resistance of the cable is not reducing the current to
the heater. This would not allow sufficient power to the
electrical element to preheat the catalyst to the activity
temperature. It is recommended to run the service vehicle
at fast idle while starting the heater.

9. Cata-Dyne™ heaters are designed to use clean fuel and
to be used in non-contaminated atmospheres. Sulphur
compounds in the fuel or atmosphere will poison the
catalyst bed over a period of time and render the heater
inoperative. If the heater has been exposed to sulphur
compounds, it should be sent to the factory for service.
10. Avoid spraying the face of the heater with high-pressure
air, steam or water because this can damage the catalyst
bed, if physical damage is visible, return the heater to the
factory for servicing.
11. Ensure that the thermostat is correct for the model size,
fuel, and pressure specifications for the heater it is fitted
to. If the thermostat is too low, the heater will not have
sufficient fuel rating to operate and will stop.
