Troubleshooting Propane Heaters

Propane Heater





Double heater - one side lights the other does not.

Most likely there is a bad thermocouple on one side.

Replace thermocouple 1035.

Heater will not light.

Is it a new tank? Can they hear the gas flow? Gas does not immediately flow from brand new tank.

Purge (let air out) of tank for about 10 seconds or so. Repeat process. Strongly recommended to take back to dealer for purging. Tank should be kept outdoors at all times.

When lighting heater and holding in plunger, heater does not stay lit or stays lit for 5 minutes then goes out.

Most likely a bad thermocouple (or a nut may be loose).

Look for breaks or kinks on thermocouple. If none seen, tighten nut. If still bad, replace thermocouple 1035.
Getting blue flame (see next example also).

Not getting right  mixture of propane and air.

First check the opening, in either the venturi tube or the orifice. Blow air through the orifice, or use small wire probe making certain it is clean. Make sure nothing is in or blocking the venturi tube.

Heater has small flame.

Orifice may need to be cleaned out - may be plugged. Cobwebs in the venturi tube.

Clean orifice with air gun to blow out any debris or use small wire probe. Clean venturi tube with air gun or match stick.

E-Z heater will not spark.

Electrode not connected to igniter or electrode not pushed in enough in igniter.

Check wire connection to igniter.

Heater is burning in back of screens. May also notice a loud roaring noise.

Screen could have holes in it or be worn out (uneven or buckled screen surfaces). Regulator might be set too high.

Replace new screen assembly 1040 (screws for replacement included). Use 1/8" drill bit to drill out rivets. Take care not to bend reflector. As a last resort, snap off small cap on regulator knob. With heater lid in the high position, use an Allen wrench to turn brass adjusting screw 1/4 turn counter-clockwise, which will reduce the heat slightly. Repeat as necessary.

Troubleshooting Indoor Gas Lights




Gas light mantle has turned black. Bad mantles (too short inside would get too hot and burn out mantle). Replace mantle.
Bunsen has spider webs (most common reason for mantles turning black). Clean Bunsen.
Need high altitude nozzle (above 4500 ft. - has smaller orifice). Install new high altitude nozzle (1.9 - 52A).
Using incorrect orifice for natural gas vs. propane. Install new natural gas nozzle (1.9 - 51A).
Gas light mantle is broken. Touching mantle (pre-formed will crack and burn through even with flames). Replace mantle.
Breezes, bugs and vibrations will also break mantle. Replace mantle.
Gas light pulsates or flickers - does not stay lit. If gas light is new, nozzle (orifice) could be clogged. Blow air through to clean. Because the orifice is a very soft brass do not insert anything in the hole. May need new orifice.
Check Bunsen for spider webs, lint or fiber. Clean Bunsen.
Check for lint or fiber in burner nose screen. Clean burner nose screen. May have to replace burner nose.
Gas line used should be no smaller than 3/8". If 1/4" must be used, run can be no longer than 8 ft. Check installation.
Regulator is bad, LP gas must be 11" on water column (6 oz. mercury) pressure. Check installation. Who installed? Was the testing equipment correct? Was regulator at tank checked? Check at wall connection also.
Wallplate may have been bent during installation, impairing gas flow. Loosen installation (but wallplate may have to be replaced.)
OPK Kit - one light is brighter than others. May be a mantle problem. Try another mantle - or try switching mantles.
Plugged nozzle (orifice) in wallplate. Blow air through to clean. Do not insert anything into hole (very soft brass). May need a new orifice.
Flames shooting from mantle in gas light. Low pressure regulator not being used. Gas lights are low pressure - the regulator in the line should be 11" from column. Would mostly likely be lack of a regulator because low pressure is not enough to cause a flame. Have a low pressure regulator installed. Have the pressure checked by your installer.
Seal has been broken. Each time burner nose is removed from Bunsen tube, a new seat is required. Put in new seal.
Cracks in burner nose. Need burner nose.

Note:  If you have more than one gas light installed, switch manufacturing gas light parts with your good gas
 light parts to determine whether the problem is with a gas light part or pressure.
