Question about Rinnai RHFE-1004FA 38,400 BTU Energy Saver Ductless Heater - LP Gas

2 Answers

Rennai 551 FA-P Never fully shuts off

When the room temperature has been reached the flame lever reduces to low but never shuts completely off.   When I increase the temperature setting the flame increases and the unit sends out more heat.

Hebert,

Is there a chance there is a draft around the room temp probe? It is down low on the right side of the heater. If there is a draft the room sensor is fooled and keeps running the unit. You should be able to prove the room sensor by putting your hand over it after the stove has been running for a while. This should shut the stove down. If not there is a problem with the room sensor.

Why does the heater turn off?


If it's thermostatically controlled, if shuts off the burner when it reaches the set temperature. Is the pilot flame going out too? These heaters require a certain amount of fresh air to operate properly. If the oxygen level gets too low, it is designed to shut off completely for your safety.

Fan on gas wall heater shuts off and on every 3 minutes, but the flame is on the entire time.


It always helps to add the model number of the item you want help on. However if it's like the newer units, the fan operates whenever the heater wall has reached a high enough temperature and shuts off when the heater cools off. It is not wired into your thermostat or electrically wired to the heater. It does that with a temperature driven fan switch in a little junction box mounted to the heater. Normally when that box gets hot because the heater is on the fan comes on, when it cools off the fan goes off. The junction box will have an ac cord coming out of it. If this fan switch junction box is not properly mounted it could be getting cooled off when the fan starts and then shuts itself off. After it heats up again it starts the fan. The other possibility is the temperature based fan switch is failing and needs replacement. See link.

I start the pilot up... burners go on but once it reaches temperature the burners shut off and dont start up again????/ what could be the proble


Hi there.
Check the thermostat, it may have a mechanical defect (not closing contacts once it reaches the cut-in temperature).
If the pilot flame goes out with the burner flame once the ste temp is reached, your fryer may have problem with the hi-limit (premature tripping).
Regards.

Hi, sounds like the MGV is not shutting off all of the way/ That would be the only reason gas would continue to flow, even on a small scale. If this keeps up, change that valve!! Do not take it apart, never! Good luck,

Utika boiler does not stay on


What is the fuel you heat the boiler with?-- Oil or Gas?

Does the flame ignite initially, and then sputter out- or positively SHUT off, like a valve is closing?

Is there a High temperature (or Pressure) limit being reached, to shut it off?-- or other controls, like: Low Water, Hi Temperature plenum switch? --
can you do some trouble shooting, and get back with us, so we can help you better?

I have replaced the thermacouple on my pitco fryer but the reset button keeps kicking out,shutting off the pilot.\r\n can you help me? thank you in advance.


If the reset button trips on low oil temperature, check and make sure that its sensing bulb located inside the fry tank does not touches the fire tube. This device is called the hi limit, it is the unit's safety device designed to shut the pilot flame when oil temperature reaches 450F.

Hello, I can assist you.

If the unit is supposed to turn off and it doesn't, it will be necessary to check several things.


  • First, is the unit cooling properly? See the section entitled "The air is cool but doesn't seem cold enough."

  • Next, is the temperature of the room adequately cool? If the room temperature is cold enough try setting the thermostat to a higher temperature. If the unit then seems to work properly leave the thermostat set to the higher temperature.

  • If the unit is cooling properly when it is turned on and the room is not cool enough the problem is probably that the unit is trying to cool an area that is too large for its capacity. Use the following chart to find the appropriate size air conditioner to use:

AREA TO BE COOLED / CAPACITY (BTU/HR)

100 to 150 square feet = 5,000

150 to 250 square feet = 6,000

250 to 300 square feet = 7,000

300 to 350 square feet = 8,000

350 to 400 square feet = 9,000

400 to 450 square feet = 10,000

450 to 550 square feet = 12,000

550 to 700 square feet = 14,000

700 to 1000 square feet = 18,000

If the room is heavily shaded, reduce needed capacity by 10%

If the room receives a lot of direct sun, increase needed capacity by 10%

Add 600 Btu/Hr for each person in the room if there are more than two people

If the unit is for a kitchen, increase the capacity by 4,000-6,000 Btu/Hr.

If the room size is too big for the air conditioner you have two possible choices. Either decrease the room size by shutting some doors or partitioning off an area of the room. Or, increase the BTU of the air conditioner for that room by installing a different air conditioner with a higher BTU rating.
