What to do if the gas furnace malfunctions?*
Wait – is that your gas furnace blazing fire through the pipes? Quick! Run out of the house before it is too late! Well, you can do that and wait for the emergency services to rush in just in time to save your home, or you can act sensibly and turn off the gas furnace supply before you rush out.
Also, remember to pull out the pilot tray that is lit in the gas heater, if you have any. The pilot tray shall have a flame which is very dangerous in case there is any gas leakage.
