7.4. Operation Limits
Operation gas pressures of natural gas for gas firing unit is 20mbar. Maximum compressive strength of the
device’s gas pass is 60mbar and in case this value is exceeded the device’s gas pass equipment will be
broken and the device will become out-of-order.
And on the air side, the standard product works until -15°C without any problem. For temperatures under -
15°C, the system is made to work without any problem by using over-device, electric heating type gas firing
units.
Please refer to the capacity table for unit capacity values.
7.5. Controls to be considered before commissioning
The device should be checked in terms of compliance with the rules determined by local authorities.
These unit devices could only be used at uncovered areas or semi-covered areas with very good ventilation.
People without technical competence shouldn’t be let to intervene with this device.
Don’t start-up the device before complying with producer’s instructions.
Special gas distribution tap should be attached according to gas type to be used in devices.
Gas type, power source, unit adjustments should always be checked. The device should be made sure to
operate in compliance with its adjustments.
There should be assuredly at least an opening of 2 meters on gas module side. This both simplifies
intervention with the device and enables to let the device slide air in easily.
Exhaust chimney of combustion unit must be placed somewhere away from the ambient where people might
inhale it. Released suffocative gasses cause vital hazard for all living creatures.
Products given with the device should be used in the device’s gas transformation. Use of products other than
the ones provided by the producer may lead to malfunctions. It shouldn’t be forgotten that this situation will
end the warranty of the device.
Unit’s gas pass connections should be checked in terms of compliance with the instructions.
WARNING: Never use fire for gas leakage test.
7.6. Commissioning

7.7. Service and Maintenance
Please refer to the maintenance section mentioned at the Section 13 for service and maintenance the unit.
7.8. Failure and Troubleshooting
You may see the failure codes of additional heater with gas firing on control panel inside the gas firing unit.
