When the component needs to be de-rated for both temperature and altitude, the de-rating factors given in the respective tables should be multiplied together. When a component, like liquid-cooled FC, has both air- and water-cooled parts, derating should be calculated for both parts of the respective ambient- and coolant temperatures. iom government tax servicesWebAltitude can have an effect--but probably from two mechanisms... One is temperature--Above ~5,000-7,000 feet, many electrical devices need power derating because there is less dense air and less cooling effect. The other is that many batteries have a pressure vent and less air pressure will let the batteries vent at low pressures. ontario bargain outlet flea market

The water heater manual says it works great up to 4500' elevation, then must be "derated" 4% for every 1000' elevation. So if I go camping at 9-10,000' in the Rockies, I need "derating" by up to 40% This is to be done by a pro, sez the manual. WebHigh Altitude Modifications In most cases a gas water heater will be able to operate properly up to 2,000 feet above sea level. However, if you are above 2,000 feet you'll need to make some modifications. A gas water heater can be adapted to atmosphere changes by adjusting the air-fuel balance. There are 2 options to make these adjustments:
