Question about Procom ML300EBC Heater

1 Answer

Runs fine for 2-4 minutes then shuts down.. auto..

I couldn't provide a 3 feet head room it is at 16 inches. It seems like as soon as the internal fan kicks in it shuts down.. Is the thermocupal cooling and then shutting down ?? OR potentially O2 sensor given the high/clearance issue.. I have installed in my garage and would like to keep it higher to eliminate the kid hazard potential issue.. Spoke with an installer and they feel it is the clearance issue.. But, I am hopeing that is not the case.. Thoughts ???

How old is this heater? does flame stay on thermocouple? what is the make and model # then i can look up some manuals of the heater and maybe give you some thoughts of what is going on. clearance could be a problem but i don't think it is.

    how long do you run the heater before you turn on fan? I talked with a procom rep. he said you do need the 36" clearance since it is a vent free. i could not find that model # on there site. I would try to lower the heater and see if that makes a difrence.

How to calculate cubic feet ?

Calculating the cubic feet of a space requires multiplying the area of the bottom times the average height. You get the bottom area by multiplying the length times the width. Remember, to get cubic feet, you need all your measurements in feet to start with.

Here is your formula:

VOLUME (in cubic feet) = Length (in feet) X Width (in feet) X Height (in feet)

If it's a rectangular room you're working with, it is all straightforward. If there are irregular walls, it may be necessary to divide up the room into rectangular sections and then add together their individual volumes. If the ceiling is sloped, you need to use the height that has the same ceiling area above it as below it. Good luck! Truly.

Trouble with Maytag Legacy gas Dryer

Please provide the model number and I will see if I can figure something out.
It sounds like you have covered the common problems. Usually a motor is the cause for this problem, it gets hot and shuts down until it cools off. I have had some problems with the auto dry controls on the Maytags also.
Are you equiped to do some voltage checks if we need too? This would help in knowing where you have power when it quits.

Flotecpump runs for 5 minustes or less and shuts down due to over


With a 1-1/2 inch suction and a 2 inch discharge, you have no backpressure, and it's actually beneficial to have a working head. Try pinching the discharge valve to maintain a steady discharge pressure of at least 20-30 psig on the pump case. Tinker with the discharge pressure as required to balance the pump. As a general rule, the suction line is never smaller than the discharge line to prevent cavitation of the pump. A temporary move of pinching the discharge will compensate some, but it is better to increase the size of the suction line, if the pump will handle it. If the rated pump volume is low, you may also be trying to exceed it's capacity, and heat wil result in the motor.
If at all possible, convert the voltage to 220v as this will also make you more effecient and pull half the amps. Most pumps can be wired either way, and usually the diagram for swapping is included or inside the motor housing. Converting is easy.

make sure your wireing is up to the job and your back presure at the pump discharge is within limits. both of these should be in your pump book that comes with your pump. If you don't have one you should be able to look it up on-line or order one from Pentair.

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:


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.
