Some regulators have a flip switch that prevents the valve in the top of the cylinder from being depressed, effectively acting as an OFF switch. 2. The only thermocouples I recommend are made by Johnson Controls. The failure to do this will cause an alteration in combustion air and the flame stability is affected. Specifications of Olympian Catalytic Heater Wave 8 - LP Gas Powered - 57351: BTU Level: 4200 To 8000 BTU: Heated Area (SQ FT) Heats Up To 23 Feet RV Or 290 Square Feet: Portable: Yes: Type: Catalytic LP Gas Powered: With Adjustable Heat Setting: Yes: With Built-In Piezo Electric Starter: Yes: With Leg Stand: No: With Shut Off Valve: Yes A thermocouple or flame sensor is a device used to control gas flow in gas water heaters.On older-style heaters with standing pilot lights, the device is typically called a thermocouple, while on newer units with electronic ignition, the same (or virtually the same) device is called a flame sensor.For our purposes, we'll refer to both devices as the thermocouple. They are joined together at the tip (Hot Junction). With a full cylinder in place, turn on the gas and listen for the burner to heat the gas. When there is high demand for heat (very cold weather) the temperatures that are created in the chamber have an adverse affect on the pilot and thermocouple system. There are four readings we are going to take they are. It heats the rig up very well, and on 10 degree days, setting it on high it can just about cook you outta the motorhome.

Many times corrosive chemicals and airborne contaminants are being drawn into the air gas mix and a chemical reaction takes place. However, about 85% of the time, it is the thermocouple giving the problem. The machined path in the brass for the heater enables exact repeat-ability of heat profile.By never exposing the coil heater to molten brass there are no risks of shifted heater coils, or destruction of the thermocouple junction. 1 per box. Due to their straightforward design, on the rare occasion that one of these heaters does not work correctly, troubleshooting them is also straightforward. When heat is applied to that hot junction, a small millivoltage is created. The thermocouple is a device made up of two dissimilar metals. A thermocouple that tests below 25 millivolts won’t be able to keep the pilot flame lit. Irrespective of the type of heater you own, be it an electrical heater, propane heater, or a natural gas heater, each has its troubleshooting techniques. 1600-2800 BTU adjustable output. 100% safety shut-off valve prevents non-ignition fuel discharge.

CLOSED CIRCUIT - This measures the millivolts used by the coil in the electromagnet. If the patio heater has an electronic ignition system, there should be a spark. The thermocouple is usually shaped like an inverted “v” and sits in the pilot light’s flame. Catalytic heating is 99.98% efficient, resulting in a low-cost heat. You need a multimeter with a DC volt scale, as the millivolts generated are DC volts. Also includes piezo automatic electric starter and 100% safety shut-off valve. Bakelite knob OD 38mm, D shaft 6.1mm. Sometimes the pilot lights can move too far away from the thermocouple. From United States.
