Troubleshooting a Gas Fire Pit
A gas fire pit is a good alternative to a wood fuel burning stove. It is an easy-to-install outdoor fire that adds to the quality of outdoor living. The pit is contained in a raised frame above the ground. It is fuelled by propane, a liquid gas which is supplied to the pit via a pipe attached to a propane tank. In most cases, you can purchase the fire pit in a kit form. You are spared from messy clean ups with a gas fire pit which makes it all the more welcome for residential use. Below are some of the common problems and solutions for this fire installation. These problems may occur upon installation or in the course of time.
1. No Spark when Ignited
Check whether the ignitor has the required battery. Usually, the battery is found within the ignitor. Open the ignitor as per the instructions for your specific model. If there’s no battery, insert the specified battery and try to ignite. If it doesn’t ignite, check the connection between the ignitor knob and ignitor box. It is possible that the wire may have disconnected during shipping. Connect the loose wires and ignite.
2. Delayed Ignition
Your burner may ignite but it takes a few moments to do so. Usually, it should spark immediately when ignited. Check the pressure. If it is low, contact your gas supplier for support. Inspect the gas valves to confirm if they’re all in good order. Replace any faulty valves to enable proper gas flow. The burner ports may be dirty or the orifice is blocked. Clean the ports and clear any blockages from the orifice.
3. Burner Lights but Extinguishes
Excessive draft can easily extinguish your burner. Shield the fire pit from the wind or relocate to a site where it isn’t very windy. Low gas pressure can also extinguish the burner. Check your gas supply to confirm if pressure is okay. If pressure is low, contact your supplier for support. It is also possible that your burner has dirty or clogged ports. Examine these. If dirty, clear the blockage and clean the ports. A faulty valve could keep the burner lights from operation. Check the valve and if found to be faulty, replace it.
4. Burner Backfires
In most cases, this is caused by dirty burner ports which may also be clogged. A blocked orifice could also contribute to this problem. Refer to the manual section of your fire pit and clean the ports accordingly. Check the orifice opening and clear all dirt that you may find there.
5. Black Smoke when in Use
Check the burner ports for any blockages. Clogged ports restrict proper air flow which creates black smoke. Check the orifice in the unit to confirm that it is for a propane burner. Errors do occur during assembly. If yours is fitted with a natural gas orifice, make arrangements for a replacement. Check the mesh on the piping and make sure it is in the correct position. The mesh is usually underneath the burner. For a propane gas fire pit, the mesh should be fully open but partially closed for a natural gas fuelled fire pit.
