Laura Streitman says deciding to install three wood-burning fireplace inserts in her Butler County home was not a tough decision.
“It was the cost,” she says about heating the all-electric home. “The first bill we got, I think, was about $650.”
The closed circuit test will tell you the voltage drop across the main operator coil. With the switch or thermostat closed, place your meter leads on the TH and TP terminals and measure your drop in mVDC.
To ensure a smooth ignition, when the valve first opens after turning on the main burner, no more than four (4) seconds should expire before the burner has completely lit off. Although problems with delayed ignition are most likely to occur with propane (because it is heavier than air), it can still affect natural gas appliances.
Trouble Shooting Main Burner Outage on a Gas Fireplace or Stove
1. Ensure that main burner goes out on its own and pilot light remains lit. If pilot goes out as well, refer to 'Pilot Flame Outage'.
1. Check if pilot flame goes out on its own or when main burner is on.
When checking inlet and manifold pressure, there are many different tools that will do the job. The manometer is one of the least expensive and also one of the best because it allows you to calibrate it every time you use it, ensuring an accurate reading. The manometer is a U shaped tube filled with liquid which has a valve or stopper at the top of each riser. In between these risers is an adjustable scale that is measured in inches which allows calibration of the manometer.
Another quick check you can carry out is the system resistance check. This will verify whether your control circuit has too much resistance in it.
There are two instances where you will measure resistance when checking a valve for faulty main burner operation.
On natural vent appliances incorporating a vent safety switch (VSS) as part of the thermocouple circuit, you can use the ECO (energy cut off) or terminal block on the thermocouple as a test point for gathering information. By removing the VSS wire on the pilot assembly side of the terminal block and then touching your meter probe to this point, and with your other on the thermocouple casing, you can obtain the open circuit reading.
The open circuit test will tell you the amount of voltage that the thermocouple is capable of producing without any load, or when it is disconnected.
