COMBUSTION TEST/ADJUSTMENT
The installer must perform a complete combustion
check to ensure the following combustion levels are
met at high and low input firing rates and the burn-
er is operating at optimum conditions.
The combustion testing and adjustments
must be performed by a qualified installer,
service agency or the gas supplier. All com-
bustion measurements must be perform with

duction of carbon monoxide, which can
cause severe personal injury, death or sub-
stantial property damage.
