SOURCE: portable radiant convector heater -burner slightly faulty

you probably need to adjust the primary air mixture. There should be shutters on the front of the burner assy. If this does not correct the problem you may have dirty burners themselves. you could remove the burners and drag a wire brush across them to clean. but do not drills the openings unless you use a r&m bit

SOURCE: flame burns to high

I had this problem. From using the center brick most of the time, lots of dust bunnies build up in the gas chimney behind the brick.
Tie 2 pipe cleaners together with a small perpendicular circle at the top and carefully remove the dust bit by bit by twirling the cleaner.
The brick should fire like new if it is carefully cleaned out.

The burner and anything else that was damaged. You might want to get the advice of a local professional. Remember, this thing runs INSIDE your home, where you live, eat and sleep. You want it to be safe, my friend.

SOURCE: flame on infrared wall heater

Check the gas line pressure before the heater then after the regulator. It sounds as if you are not getting sufficient gas pressure to the burners. Two possibilities bad regulator and or bad gas valve! Sorry I can not be absolutely sure on this one you can try blowing the ceramic burners with a compressor this will clean them rite out.

You may have to install a pressure regulator and cut back the gas pressure to get the flame to a level where it will not soot...
or if you already have a pressure regulator in the line then open the center of the regulator and turn the screw up a few turns at a time till it stops sooting...

This should get you running and enjoying your new fireplace..

We just put a new bottle gas in our heater but the flame is dancing now and not going in to the plates behind. The pin is also getting orange from the heat. Whats wrong.

From what you have described, it sounds like the venturi valve of the burner is dirty and/or clogged. In other words, it's not getting enough air to gas mixture to burn as it should.

Since yours is an Infrared Portable LP Gas Heater, it's not difficult to dismantle the front of the heater's cabinet to remove the ceramic plaques and gain access to the burner & all it's inner workings. Before you even attempt this, TURN THE HEATER OFF AND ALLOW IT TO COMPLETELY COOL.

There should be 6 to 8 sheet metal screws around all sides of the heater cabinet that will need to be removed. After that, carefully remove the ceramic plaques and set them well off to the side. With a vacuum cleaner that has a hose and brush attachment, thoroughly vacuum all of the interior of the heater, as well as the burner(s). Look for the open end of the burner, that has a gas line/tube running into it. That's the Venturi Valve. You should see some small slotted openings (on some models, it looks similar to fan blades). If you have a crevice tool for your vacuum, use that to thoroughly vacuum the Venturi Valve.

While you're cleaning, use a can of compressed air with a straw nozzle (like you clean your computer with) to blow out the pilot opening and the Oxygen Depletion Sensor (ODS). It will be a small hose in the side of the pilot a little over half way down from the pilot tip. Place the straw nozzle just barely into the hole and give it a quick blast of air.

Once you have completed all of the above, reassemble the heater in reverse order of how you took it apart. Make sure the ceramic plaques are positioned and aligned properly and all screws are reinstalled in the heater's cabinet. Light the pilot as you normally do and turn the control valve to the ON Position. Do the burner flames now appear as they should? If so, you solved the problem. Make that heater cleaning, part of your annual routine maintenance on the heater. Usually, in the Fall before you fire it up for the heating season.

Hope this helped you troubleshoot and solve the problem. Please let me know. Thanks.

Panel won't hold a flame

this could have to do with the main gas feeds to the ceramic panels . they might be obstructed with a spider web or dirt,foriegn material etc.
easiest fix is to take a air compresser with a blow gun tip and blow out ant foriegn material or spider webs from the gas feed pipes to
the ceramic burners.
the gas feed pipes have large air induction holes that a small blow gun can fit its nozzle into to blow out the gas feed pipes without
having to disassemble them.
that is a big time & work saver.
I took my gas feed lines to the ceramic burners all apart, only to get out a spider web that i could have blown out with compressed air and saved myself 2 hours work.

anything inside the gas feed pipes to the ceramic burners will result in dark spots or the panels not staying lite, irratic burning
or no burning at all.
the gas needs to be able to get through unimpeded at proper flow and proper pressure for proper burning.
a spider web will mess up proper gas flow. some gas, but not enough gas will get through and ceramic wont burn well and might not hold a flame.

clean out the foriegn material from the ceramic gas feed lines.

Rare posibility,if the gas behind the ceramic element escapes around the edges of the ceramic, through a bad seal of the gasket,
this also will stop the ceramic from burning well.

mr heater is not made for easy diaassembly so try not to do more work than you have to.

use compressed air rather than taking mr heater all apart to clean out a gas feed pipe.

Service code ROL raypak pool heaters p-r-266a-en-c

This indicates the flame roll out safety switch is bad. This part is usually mounted right above the burner tray. It is a white ceramic piece with two wiring terminals and an external part that looks like a resistor. This part detects flame/heat coming out from the burner tray. When replacing it, be sure to check for blockage at the burner tray, heat exchanger and the flue if vented with duct work. This is a critical safety device so do not bypass it.
