Can't adjust flame

Control knob pulled out (came off) and when it is pushed back into place it no longer engages the ratchet mechanism to raise and lower the wick. It will only turn thru a very small arc and then stops.

Re: Can't adjust flame

Sounds like maybe you need to reset the emergency shutoff:
Turn the knob all the way to the left, then depress the small lever that is inside the hole to the left of the knob. While holding down the lever, turn the knob to the right until it stops. If the unit is working right, you will hear a rachet-type sound, which resets the shutoff mechanism. You should then be able to adjust the wick.

Gas fireplace manuals

There are two things that control flame height gas volume and air volume. Some fireplaces have a flame control knob on the gas valvd to adjust flame height. Air volume is controlled by an air shutter usually located where the main gas orifice enters the burner. There is usually a small cover that will need to be removed to access the shutter. Closing the shutter will cause the flames to become taller and more yellow colored. Closing the shutter too far will cause sooting problems so great care should be taken in adjusting this shutter.As a rule, L.P. gas fireplaces do not have as high of a flame as natural gas unit do.
Hope this helps

RHFE Rinnai 551FT gas heater is not working after 7 years

see this steps and fix it. God bless you
If there is no heat, check the electrical service panel for a burned fuse or tripped breaker. Relight the pilot light (see below).
If there is not enough heat, adjust the burner air shutter (see below); and clean the burner ports (see below).
If the pilot light does not light or does not stay lit, clean the pilot orifice carefully with a toothpick, test the thermocouple and replace it if it is faulty (see below).
If the flame flickers, adjust the pilot (see below).
If there is an exploding sound when the burner ignites, adjust the pilot to a higher setting and clean the pilot orifice and the burner ports.
If the burner takes more than a few seconds to ignite, clean the pilot orifice and adjust the pilot light.
If the burner flame is uneven, clean the burner ports. If the burner flame is very yellow, clean the burner; open vents in the furnace room to provide more air; adjust the burner air shutter.
To light the pilot on a standing-pilot (always on) ignition system, follow the lighting instructions located near the control. Otherwise, try these steps:
Light the pilot:
  1. gasfurnace1.jpg Press and hold the pilot control knob to start the pilot. Set the control knob to the pilot position. Hold a long match under the pilot gas port.
  2. Press the control knob; the pilot should light. Hold the control knob down until the flame is burning brightly (about 30 seconds). Release pressure on the knob, and turn it to the on position.
  3. If the pilot goes out when you release the control knob, try relighting, holding the control knob down longer. If the pilot again goes out, check the thermocouple (below).
Adjust the pilot:
  1. Remove any cap covering the pilot adjusting screw on a combination control.
  2. Turn the adjusting screw counterclockwise to increase the flame or clockwise to decrease it. It is correctly adjusted when the flame envelops the thermocouple bulb by 1/2 inch and appears dark blue with a small yellow tip.
Test and replace a thermocouple:
  1. Hold the control knob to pilot and light the pilot as above.
  2. Unscrew the thermocouple fitting with an open-ended wrench.
  3. Set a multimeter to the DVC (lowest voltage) scale.
  4. Clip one multimeter lead to the end of the thermocouple tube nearest the pilot and the other lead to the fitting on the other end of the tube.
  5. If the multimeter shows a reading besides zero, the thermocouple is functioning. Replace the thermocouple tube.
  6. If there is no reading, you will need to clean or replace the thermocouple following steps 7 through 11.
  7. Release the control knob and shut off the main gas valve on the gas-supply pipe that leads into the burner. Shut off power to the burner at the electrical service panel .
  8. Remove the thermocouple from its mounting bracket.
  9. Wipe the combination control clean and install a new thermocouple, tightening it by hand, then give it a one-quarter turn with a wrench.
  10. Insert the thermocouple into the pilot bracket, being careful to not crimp the tubing.
  11. Turn on power to the furnace and relight the pilot (above).
Adjust an adjustable burner air shutter:
  1. Set the thermostat to its highest setting to keep the burner running. Once the furnace has heated up, remove the burner access panel and loosen the locking screw.
  2. Open the shutter by turning it to the right until the blue base of the flame appears to lift slightly from the burner port surface. Then close the shutter until the flame reseats itself on the surface.
Clean removable burner tubes and ports:
  1. Shut off gas and power to the furnace.
  2. Unscrew or loosen and remove the tubes from the supporting bracket.
  3. Carefully clean the tubes with a brush or vacuum, making sure not to damage the burner ports.
  4. Use a stiff wire to clear any debris from clogged ports.

How di i light the pilot light

Be sure that the gas line to the heater is ON.

Looking at the Control Knob on top of the heater, you note that he knob has 3- positions: OFF, Pilot, ON.

Turn the control knob to the Pilot position and push down on it. If it does not go all the way in and your do not feel strong pressure pushing back at you, it is not directly in the pilot position. (Reposition the knob slightly and try again). Once You're sure the knob is directly in the pilot position and the knob is depressed, continue to hold it in and press the Ignitor button next to it. You will hear a loud click. If possible, watch the pilot assembly inside the heater when you do this. That way you can see if the pilot lit the first time. If not repeat, pushing the ignitor.

If the gas line had been turned off to the heater, the pilot may not light the first couple of tries, due to air being in the gas line. If that is the case, hold the control knob in until you smell gas, let off, wait 5 minutes and repeat the lighting sequence.

Once the pilot does light, continue to hold the control knob in for 1 minute. This will allow the Thermocouple to heat up completely. Ease off the control knob and the pilot should remain lit. If it does, turn the control knob to ON and the burner will light.

Now you're ready to set the temperature or comfort level. You do this by raising or lowering the flame height. The higher the flames, the more heat it puts out. The lower the flames, the less heat it puts out. The stripe on the knob represents the flame heights - Narrow stripe, lowest setting, widest strip, highest setting. Or your specific model may simply say Low, Medium, High.

If you do not have the Owners Manual for this heater go to
click on Wall Heaters and enter the Model Number of your heater. You can then download and print the Owners Manual.

Hope this helped to get you up and runnig.

How do i change the wick?

You need a pair of Pliers, a flat-tip screwdriver and a plastic bag (for old wick)
ALSO - make sure the tank is empty (or as close as possible)
1. Turn the control knob to OFF.
2. On the left and right side (bottom, just under the wire cage are two cabinet screws. Remove these.
3. Using the handle, lift straight up to remove the cabinet (entire upper assembly)
4. Gently pull off the wick adjustment knob (you will need to push in the little square button.
5. Remove the "dressing plate" (the ring about 3" high) that the "Off" "Low" and "High" markings. The chain attaches this the fuel cap, but you don't have to remove the cap. Just set the "dress plate" ring aside as far as the chain lets you.
6. Either trip the manual shut-off or push against the wobbly pendulum to the left of the control knob shaft to drop the wick all the way down.
7. Remove the four wing nuts that holds the heater on the wick assembly and carefilly lift teh sick assembly from the heater.
8. Reset the automatic shut-off, put the know back on temporarily and raise the wick all the way.
9. Turn the Wick Assembly upside down. Place the white plastic strip, packed with the new Wick, on the Wick Cover to protect your fingers.
10. While holding the Wick Assembly upside down, pull off the Wick Cover with a sharp tug.
11. Remove the Wick while folding it to the inside. (Remove the Wick Sleeve together with the Wick).
12. Take the new wick and insert the Wick pins into the three holes of the Wick Sleeve. (Make sure the short portion of the Wick is UP.)
13. Attach the Wick wo the retainer teeth of the Wick Sleeve stick into it, making sure the Wick fits evenly arount the inside with no wrinkles or bunching.
14. Fit the Wick and Wick Sleeve back onto the Wick Guide, making sure you fit the pins through the slanted grooves of the Wick Guide and Press on each of the three pins from the back, making sure they are inserted securely through the holes on the Wick Guide. (This is where most people screw up Wick Replacement, so make sure you get this right)
15. Turn the Wick Adjustment Knob to make sure the Wick slides up and down freely. (Note, the wick should automatically be set to 3/8 of an inch when fully raised.)
16. Turn the Wick Assembly upside down and replace the Wick Cover by: Align the four tabs on teh Wick Cover with the four screw holes on the bottom of teh assembly and snap it into place.
17. Hold the Set Lever to down position with your finger.
18. Remove the protective strips from the Wick Cover. Turn the Wick Adjustment Knob to the fully raised position and light pull on the "skirt" of the Wick to remove any slack. Then press the skirt lightly onto the teeth on the Wick Cover to hold it in place.
19. Replace the Wick Assembly on the heater WITH THE WICK RAISED. Replace the wing nuts, tightening gradually, tightening opposites sides first(If counting clockwise, tighten screw 1, 3, 4, 2 - go through several rounds, tightening gradually so it seats evenly
20. Before further reassembly, trip the Auto shut-off and reset it to make sure it works properly. Test the Wick adjustment knob to make sure Wick slides up AND down freely.
21. Remove the knob and replace the "dressing plate ring.
22. Replace the entire upper assembly "Heater Cabinet" and repalce the two screws. Replace the Wick Adjustment Knob.

Vulcan oil heater

1. Check electricity is on.
2. Check oil is in the tank and valve turned on.
3. Switch the fan off at the bottom left hand corner.
4. Switch oil knob to No.1.
5. Set Air knob to No.3.
6. Operate re set button (right hand corner of heater under settings dial). Either press in until it clicks or if the pull out version pull out until it clicks.

Wait - ignition should take place in a few minutes and flames will appear on the left of the burner under the radiants.

You should get occasional yellow crests above the pure blue flame just visible below the top row of burner holes under the radiants.

After the red warning light goes out you can adjust to higher settings.

The radiants do not glow on low setting.

You can adjust the heater on to higher settings but this should be done gradually - no more than 2 settings at a time.

Some warnings:

* The unit must be correctly earthed.
* Do not use anything except heater oil.
* Never attempt to re-light the heater when it is hot.
* If the red light does not appear when the oil knob is switched on, immediately turn the oil knob off. Reasons include: Heater is too hot; Electric plug turned off; failure of ignition system.

Good luck - no responsibility taken for the advice (but it is largely copied from my Vulcan heaters instruction manual which I still have (installed in 1967).
