2021/4/4 · Derating Gas Burners. Derating, or down-firing, is the practice of installing a lower gallon per hour (GPH) rated nozzle in a gas-fired appliance to reduce fuel use in the event that your boiler or furnace is oversized. Doing so properly often requires reconfiguring the shape/size of the combustion chamber and/or adjusting the fuel pump pressure.
I am trying to understand the high altitude adjustments for gas boilers and what it means for the Input (MBH) and DOE Heating Capacity (MBH). The "standard" adjustment that I see is to reduce the input rate 4% per 1000 ft above sea level. For example, if the input rating is 100 MBH and the DOE heating capacity is 80 MBH (80% efficient) and the

Gas pressure. 'Minimum inlet pressure' describes the lowest pressure required for gas entering the boiler in order for your boiler to operate safely and efficiently. It's the most common specification you'll see and it's typically measured in 'millibars'. Each millibar is 1/1000th of a bar. British Gas can recommend what's suitable for you.
