Propane appliances usually run on 10-11 inches of water column, this is about 1/2 pound of pressure. If the regulator you have is not rated for delivering gas at that rate, you will need to find one that does. If your regulator is rated for more than the 11 inches, most likely you could have damaged the appliance regulator that came with the heater. Check the propane pressure specified by the heater manufacture against the rated supply of your regulator and see if they match. Make sure the heater is rated for Propane and NOT Natural Gas. Check to see if the gas valve on the appliance is in the operate position and all valves are open. Bleed off the air in the gas line by holding down the pilot switch and keep attempting to light the pilot. It could take you a few minutes. If you hear and smell gas but the unit will still not light, don't chance at getting hurt, call a technician. Look to make sure there are no safety switch that may have triggered off not allowing the gas valve to operate. And make sure there is no obstruction in the heater?s gas valve blocking off the supply of gas. Always exercise caution when it comes to gas and if you are uncomfortable, call a qualified gas technician.

SOURCE: no heat!, light blinks 3 times

Make sure the inducer motor is free of condensation and that all water is able to drain out. Unfortunately your furnace is a lower-grade “builders” model and does not have the same quality of components and workmanship as a Carrier or American Standard furnace. Prior to these failures, It was about 1/2 the price of the units mentioned. And the warranty drops off quickly. You get what you pay for.

SOURCE: turning on a radiant heater

whoo tall order! well, since that unit uses a piezo crystal spark gap that's half the battle. go to the grainger site and find a 24 volt electrically operated solenoid for gas use. anything else won't do. next go to the white rodges web site and find a spark igniter with a flame rod flame detector 24 volt. you'll also need at least a 500va 120/24 volt transformer. a standard honeywell stat will do. I'm thinking the unit uses a millivolt generator to keep the gas valve open. you could substitute a mercury button cell to energize the pilot valve and keep the valve open. give me your email addy and I'll see if I can draw up a diagram for you.

SOURCE: Quattro Plus heater will not stay alight

Does this unit have a thermocoupling?

If so replace it. (6 bucks)
It is the units flame sensor and they routinely go bad.
When they no longer sense flame the unit will shut off gas to the ignitor/burner.
It will only stay lit when you are manualy holding the button.

Sahara big burn patio heater


From the Troubleshooting Guide - Check the Obvious Turn on the gas and listen at the burner to see if you can hear the gas arriving.
If the patio heater has an electronic ignition system make sure that there is a spark. If there is a spark but the heater will not light up, try using a lighter or burning spill to light the gas. Be ready for a flash over if you have been trying to light the gas for a while-there might be a small cloud of gas near the burner.

Start at the Bottom The most likely reason that a gas heater will not work is that there is no gas. Take out the empty gas cylinder and replace it with a full one. Often you will feel that there is still gas in an empty cylinder but there is not enough to create the pressure needed to drive the gas burner. An empty cylinder will feel light.

Check the Gas Regulator The gas regulator is the connection of the gas cylinder to the gas pipe that takes the gas up to the burner. Some regulators have a flip switch that prevents the valve in the top of the cylinder from being depressed-effectively an "off" switch. If there is such a switch, make sure that it is in the "on" position.

Check the Gas Pipe Although it is most unlikely that the gas pipe can get blocked, remove the gas pipe from the regulator and from the gas inlet at the top of the heater. This pipe is pressure fitted and held in place by pipe clips. Blow air through the pipe to ensure that it is clear.

Check the Burner The burner will be a very simple assembly. Take each part off in turn and check for any blockages. Also check that the burner apertures are set correctly. Beneath each burner is a small chamber in which air and gas are mixed. Make sure that the gas and air inlets are clear.

If Your Heater has a Pilot Light If your heater has a pilot light, there is the possibility that the thermo couple has failed. The thermo couple is usually shaped like an inverted "v" and sits in the flame of the pilot light. The temperature acts on the thermocouple to keep the gas supply to the burner open. A good indication that the thermocouple has broken down is that the pilot light goes out when you try to turn the heater on. Thermo couples are readily available patio heater parts and usually available from stock.

If you have carried out all the checks and the heater will still not light, you can repeat all the checks more slowly and carefully or take your heater to a specialist for a service.

Have an rlp30 reddy heater, have spark and gas but will not light.


wile red button is pushed no flame or turns off when the button is released the flame dies ? if no flame tank is too small or spark isn't in far enough to catch gas . if flame is present with button down then the over heat switch on the in line thermal coupler could b bad u can check the over heat switch with a jumper between the two wires and if it stays lit you got it if it goes out then its the thermal coupler that's bad

Not getting any propain to my patio heater


First check the gas, connect the regulator to the cylinder but unclip the hose and do not light the heater. Turn the gas on for a second to see if the regulator is working OK. Next make sure there are no blockages in the pipes up to the burner. If all clear then vent the pipes to clear all air. If still not getting any gas the problem could be a faulty tilt switch cutting the gas supply or a worn thermocouple. Short out the tilt switch to test and if not fixed then change the thermocouple.

Flames are coming from the top of heater bricks. Thought pressure was to high so changed regulator on gas bottle but to no avail..! What else could it be ?


haven't had any time with delonghi heaters but usually the gas pressure can be controlled at heater by the valve they usually have hi/low adjustments on them there usually is a screw that is covering this adjustment and you must use your manommater to set heater to its high kpa rating (usually a slight adjustment under its hi setting is better to set too), changing the regulator will only change the supply gas to heater not the burning pressure which is done at valve in heater and most heaters regulate there own pressure so be careful using regulators they can drop the pressure to much to a heater and not let enough gas pressure through to heater so it can run at its full efficiency i have seen this done on a commercial job when comissioning heater could not get more than .5Kpa on .8Kpa natural gas appliance, your appliance L.P.G so pressure will be higher on hi setting but i'm guessing should be set at valve in heater or you could just have a faulty valve in appliance if you can't set valve

Honeywell RTH230B will not call for heat.


On a call for heat an internal switch should connect Rh and W, if it does not the stat is bad. Try it with no wires connected.

Gas supply keeps cutting out


I'd be checking what the operating gas pressure is correct - when it's operating, not when it's stopped or off. My suspicion is that the gas pressure is incorrect & the regulator needs adjusting, or that the gas bottle is simply too small for the heater & can't evaporate enough gas to keep it going. You really need a gas expert to advise on site. Regards, Greg (Aussie gasfitter - too far to do house calls)
