*Maximum Straight Flue/Air Intake
Electrical load at 230 V 50 Hz measured by calculating from total run current of appliance.
* Do not exceed the maximum length of flue stated or heater may not operate properly.
Reduce the maximum length stated by 1 m for each 90° bend installed.
**If minimum air flow requirements are not met, then temperature limit devices will shut down the heater.
