PILOT FLAME PATTERN
Two pilot burners with ODS function for NAT and LP gas respectively are installed on burners two sides
separately as shown in Fig. 11. The normal ODS pilot flame should have a correct pattern as shown in
Fig. 12 in normal operation with exception during ignition stage.
WARNING: If yellow tipping occurs, your heater could produce increased levels of carbon monoxide.
If burner flame pattern shows yellow tipping, follow instructions at bottom of this page.
Notice: Do not confuse orange flames with yellow tipping. Dirt or other fine particles enter the heater and
burn causing brief patches of orange flame.
