Everyone wants to get the most out of their equipment whether it be for heating and cooling or anything else. If we can save a few bucks every month then its good we saved that money and energy for the future. This article is applicable to those people with gas or oil furnaces, gas or oil boilers, and or gas or oil fired water heaters. Basically any appliance that burns fossil fuels and has a flue through a vent or a chimney this article is applicable to you and can save you money by saving energy.

Gas Furnace Components 2

90 Plus Furnace

Gas Manifolds – The furnace manifold connects the valve with the main burners and it is important that the proper pressure be present inside the manifold for proper combustion. Manifold pressure is different from natural gas to liquid propane and this pressure needs to be set with a special instrument which the HVAC installer or HVAC start-up technician should have. The manifold pressure should be set according to the furnace manufacturer’s instructions and is done by an adjustment on the regulator and valve as noted in the valve section (see gas furnace components). The setting will depend on the type of fuel, natural gas or LP, and the manufacturers instructions.

How to Test a Thermocouple with a Multi-Meter

How to Test a Thermocouple with a Multi-Meter

Pilot Burner that Feeds the Flame to the Thermocouple (not pictured)

How to Test a Thermocouple with a Multi-Meter? So you have found the pilot light will not stay lit when you try to light the pilot light. You know you have gas and everything seems to be fine so what is the problem? You ask a friend and the friend tells you the thermocouple is bad. So how do you test the thermocouple to see if it is bad or not? You will need a multi-meter that will read millivolts (most meters read small voltage like millivolts which is 1/1000th of a volt) and a source of fire such as a lighter or small torch. How to Test a Thermocouple with a Multi-Meter step by step:

Trane Gas Furnace Efficiency Factors & Fuel Purity

Trane Gas Furnace Efficiency FactorsTrane Gas Furnace Efficiency Factors - This is a Trane gas furnace. It is also called a Trane 90 plus gas furnace because it offers efficiency levels up to 90 percent plus AFUE. Gas or oil furnaces generally cannot achieve efficiency at 100% because of impurities in the fuel including moisture. This is the reason why no fossil fuel furnace sold has a rating of up to 100%. This biggest impurity in many fuels is moisture which is difficult to remove because it is in the distribution and storage places where the fuel is distributed and stored. If these impurities were removed from the fuels before they were introduced to the furnace the cost of the fuel would be much higher and the cost to benefit ratio would not be effective.
