Type H nozzles are mainly used on burners with a hollow cone air pattern and for throughputs up to 2.00 GPH. The droplet distribution is concentrated on the outside of the cone and results in good ignition and low-noise combustion.
I am an havoc technician and I have a circa 1988 Riello oil burner in my home hydronic boiler. These Delavan nozzles are the only ones that provide reliable,dependable everyday operation. Other nozzles that I have tried cause intermittent "no heat" calls.
