Safety Advice of Water Heater Gas Valve

Gas can be extremely dangerous to work with if you're not sure about what your doing. At the same time, gas safety valves is safe to work with if you do know what your doing and follow all safety rules. If you do not feel 100 percent confident and understand safety precautions, please call someone to help you.
Always check gas lines for leaks after reinstalling them. Soap and water works well. Spray gas safety valve on all connections and watch for tiny bubbles to form. If you do see bubbles tighten the connection and test again.
Before lighting a pilot stand near the water heater to see if you can smell gas. Kneel near the gas valve and smell for gas.

If you smell gas, find the leak and repair it or call your gas supplier. Don't try to light the pilot.
Never fire a water heater burner with the access panels off.
Never tap or hammer on a water heater gas valve.

FAQ burner

1 motor is running, the ignition is normal, but later downtime
(1) The magnet valve is not open, because the solenoid valve coil failures or cable breaks (1) replace the solenoid valve or exclude circuit unreasonable failure
(2) Disconnect the ground line (2) to re-examine the ground is intact
2, the device has a tightness test apparatus, the burner motor running, the ignition is normal, but later stop (no fault display)
(1) The solenoid valve does not seal (1) exclude the seal case
(2) insufficient supply (2) to improve gas flow
(3) filters (3) Clean or replace
3, the burner motor running, the flame is formed normally, but then downtime
(1) ionization current instability, is too low (1) to change the position of the flame ionization electrode plate and check the connection line
(2) gas air mixture adjustment unevenness (2) to re-adjust the gas air mixture
(3) spark ignition affects the ionization current (3) ignition transformer primary winding replace the phase and neutral

Gas burners safety valve how to care?

Gas Burner Safety Valve is boiler to protect the last line of defense, in the boiler pressure exceeds the limit, according to the valve design with a set pressure, exhaust pressure relief, to ensure the normal operation of the boiler.
1. To keep clean safety valve to prevent the valve spring stalks, etc. are full of dirt or corrosion grease to prevent the gas valve discharge pipe is clogged oil or other foreign matter; always check seal is intact, preventing the lever-type safety valve hammer loose or moved, preventing the spring-loaded safety valve adjustment screw is free to twist.
2. After cleaning the safety valve must be re-commissioning.
3. The valve should be used to clean light oil.
4. After the beginning of the operational phase of commissioning, should be carefully observed the operation of the safety valve.
5. Safety valve leaks found signs should be replaced or maintenance. Prohibit the use of increased load (eg adjusting screw on the lever or safety valve lever and hang heavy loads over tighten the spring-loaded safety valve) is the way to eliminate leakage.
6. Periodically check the operation of the safety valve leaks, appropriate measures to jamming and spring corrosion and other irregularities, and to observe the adjustment nut and adjusting ring set screw lock nut is loose, if a problem should take timely .
7. The safety valve is installed outdoors should take appropriate protective measures to prevent the rain and fog, dust, rust and other dirt pollution and invasive valve discharge pipe, when the environment is below zero degrees Celsius, freezing should take the necessary measures to ensure safety valve reliability.

Furnace burner tubing and pipe how to install

Tubing need a fuel supply system, piping is provided with a filter, control valves, check valves, valves, high and low pressure switches, shut-off valve,Safety Valve and then into the burner, the former mouth requirements for hose connection.
Trachea into gas and air, if the air is the combustion air blower, soft connection, low pressure switch, then hose into the burner.
Burner is the fuel and air mixture combustion discharged in a certain way means collectively.
Burners by type and application areas divided industrial burners, burner, civil burners, several special burner.
Industrial burners known burner, many types of specifications type, there are oil, gas, coal and several major categories. Applications is very broad, requiring fuel combustion to heat the material or the reaction of industrial applications need to use the burner.
Burner, also known as integrated burner to oil and gas-based. General application in small and medium-fuel boilers, fuel hot air oven and small fuel furnace.

Stable combustion burner "What does that mean?

Efficiency of the boiler rated load / boiler / burner environmental correction coefficient determines the power of choice of the gas burner. Power agas Burner Valves range is a gas valvemodel set later, after certain allowable gas pressure, corresponds to a flow rate range, and the greater the gas pressure, the greater the flow. Visible: the burner can be equipped with different valve, with a valve flow at different gas pressures also different boiler rated load, environmental and boiler efficiency decisions burner power, gas flow decided burner power. Set the gas flow in gas pressure determined, you can select the appropriate gas valve, the gas valve at the gas pressure must be covered and larger than the traffic. "Gas train gas mass flow should enable the boiler operation at rated load, stable combustion burner," what it means.

Gas Burner Valves action principle

gas Burner Valves action principle

The gas coming from the direction of the first one is the gas safety valves, the second is operated valve, double solenoid valve is to set up a double insurance, in case of a solenoid valve leak, and there is another to ensure that does not leak. To ensure this, there are no two solenoid valves are bad, the actual operation between the two solenoid valves is also equipped with leak detectors, once there is a valve leak, burner can not open the solenoid valve, and thus not start burner, the solenoid valve must be repaired or replaced, ensure two solenoid valves do not leak before starting the burner.

Ignition failure

Gas water heater ignition pulse ignition firing pin but not the main burner ignition failure:
Low battery 1. The gas water heater or battery connection is bad.
2. hot gas water heater switch is bad.
3. The Water Heater Gas Valves is bad or there is the phenomenon of the card.
4 .. gas water heater circuit board has contact failure or damage phenomenon.
5. insufficient water pressure or water pressure micro switch bad.
6. above the fault can not be excluded, please professional maintenance personnel to repair or service call to repair.
