Empire corcho ventless propane wall heater 15000 btu

The regulator on the heater probably is not but is probably a device to prevent the heater being used unless the gas pressure is high enough and also serves to prevent air entering the gas line and also serves to arrest flashbacks.

The standard propane low pressure regulator is 14" water gauge but the heater might need a high pressure regulator. The best way to decide which type of high pressure regulator to use, because there are several, is to use an adjustable regulator.

After installing the adjustable regulator the pressure is increased until gas can be heard to be flowing and the heater lit. The regulator should then be adjusted to produce a clean flame of the correct length and then the regulator adjustment locknut should be tightened.

If the heater is to be used indoors it is important to ensure there is plenty of ventilation and the emissions are checked by a gas engineer.

Turn off the propane tank and disconnect the heater hose from the tank. Wait 5 minutes and reconnect the heater hose/regulator to the propane t. Turn the tank valve on very, very slowly until it's completely open again. Now, try lighting the heater. If you are using a 20lb LP grill type tank, that should solve your problem.

Hope that helped.

You need to ventilate this area while the units running! This is potentially a lethal situation!
You are competing with a flame for oxygen and breathing the carbon monoxide gasses
from the heater! Both unacceptable scenarios! you can easily die in this environment!
I cannot stress this enough! You need to open a window or crack the door enough to allow air to circulte and gasses to vent out and escape, If the burning of eyes is really bad your unit may not have sufficient combustion air, I can t tell you without seeing it precisely, you better vent that room though!

First off, yes you can convert it to propane. The difference is that the orifice, which should be in the conversion kit, has a smaller hole for the gas to pass through and needs to be changed. Secondly, the air consumption on propane is greater than that of natural gas and for that reason you need to open the air venturi, usually to the max to allow the largest amount of air to enter. Don't overlook the pilot light as well, it also needs to have a different orifice installed. You can find new orifices and/or conversion kits at the store where you buy your propane, assuming it's not a big box retailer. Go to a local propane supply location for the parts. Another option is to go directly to the manufacturers home page and order the propane orifices.

what is the model # for the furnace. You are going to have to change the pilot orofice and gas valve for natural gas also.

I have tried to light my empire wall furnace by pressing the button and I have the gas on and it won't light

You can find a regulator and hose at most hardware stores or pro RV.store.

I have the same htr in Mich. & have worked on gas htrs.for many years.
Does the flame go out when you let go of the button to lite it?
If it does, then the thermocouple is bad.

If the flame stays on, but goes out when you turn the dial,
the gas regulator is bad.

Probably a little more expensive to buy new then to fix it.
