|Next remove the LPG regulator from the hose. Either cut the hose just above the regulator or unscrew the jubilee clips to remove. Generic patio heaters may fit steel gas pipes (not recommended) with shorter LPG hose than quality patio heaters.
Store with other parts.
|Loosen and remove the 4 stainless steel bolts at the top of the patio heater pole, keep one hand firmly on the burner when removing the bolts to hold it steady and prevent the burner dropping to the ground. Lift the patio heater burner off the pole, keep the hose attached to the burner. Before making any repair check the condition of the LPG hose, look for any splits, cracks or wear from top to bottom.
|Place the patio heater burner upside down on to a workbench or table. The surface or work area needs to be level to work on the burner. Old burners will have small pieces of emitter screen inside, this is normal and will not harm the patio heater. If the burner is a generic chrome or tin type, the body will be pitted with rust. It may be useful to take a wire brush to clean the burner and remove the loose rust. All branded BFX patio heaters are superior quality and supplied with high energy and latest energy efficient stainless steel patio heater burner.
|Remove the flame emitter screws by unscrewing the 4 stainless steel screws using the Philips type screwdriver. They should unscrew with little pressure but should the screws stick spray with an oil based lubricant and leave for 10 minutes to soak. If they are still stuck fast the best way to loosen the screws is to apply a flame around the screw to expand the burner casing.
Generic chrome or tin burners will struggle to open, most of the screws are steel type and difficult to remove without drilling out.
Store the flame emitter screen and 4 screws with the other parts.

The thermocouple is fitted to a large sleeve nut either silver colour as shown or on generic patio heaters it may be brass. Loosing this will reveal the electromagnetic valve.
Unless the electromagnetic valve require changing it's best to leave this on
