5.5.3 Adjusting gas valve for combustion specification
As described on the data plate, this appliance is set for naturnal gas by default. Furthemore, this
appliance can be used without adjusting the CO
Subject to the WEBBER INDEX, the CO
can be measure at the boiler flue adapter test point.
If the actual CO
value deviates from the stated ranges by more than 0.5%, check the balanced
2
flue system for leaks.
Check the discharge amount, and adjust the CO
1. Connect a flue gas analyzer probe at the flues gas connector on the flue outlet.
