Boiler Gauges, how to read the temperature & pressure

Heating boiler gauges: this article describes the combination pressure & temperature gauge found on most hydronic (hot water) heating systems. The boiler gauge gives helpful temperature or pressure readings that tell us if the boiler is operating normally. The same pressure and temperature readings at a boiler can help diagnose problems such as TP valve leaks, cold radiators, and even boiler

Gas-Fired Boilers | Building America Solution Center

The lowest efficiency boilers are atmospherically vented, Category I boilers. A Category I boiler operates with the flue at negative pressure with respect to the combustion appliance zone (CAZ), i.e., the room in which the boiler is located, and the stack temperature is above 140°F, which is hot enough to avoid condensation in the vent. The burner draws its combustion air from the CAZ.

Gas Flame Thermocouple Sensors Troubleshooting & Replacement

Remove access covers as needed: on a gas fired water heater you will need to remove the manifold door at the heater bottom in order to access the end of the thermocouple that mounts on and monitors the pilot flame. On a gas-fired furnace you may need to remove first the furnace cover and then a flame shield. Keep any mounting screws for re-use.

Troubleshooting a Gas-Fired Hot Water Boiler

On well-designed natural gas-fired systems, an excess air level of 10% is attainable. An often-stated rule of thumb is that boiler efficiency can be increased by 1% for each 15% reduction in excess air or 40°F reduction in stack gas temperature. Suggested Actions Boilers often operate at excess air levels higher than the optimum.
