Bradford White LP water Heater Power vent ,flame keeps going out

I have a Bradford White LP water Heater Power vent. I reset the unit and it fires up and everything works for a while, then the flame goes out and the power vent runs continuously. I had a similar problem a year ago and had to replace the sensor on the vent, but this seems to function properly, what else could be the problem?

I have a ecosense tankless water heater #rtg-74pvn-2 how far can i take the vent


Feb 2013
1) Rheem/EcoSense tankless product manual does not have specifications for length. Error 11 will let you know if venting is improper.
Often, tankless are installed outside because unobstructed venting is key for combustion of the amount of gas coming out of 3/4" gas line.
http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html

2) Copy following link for Bradford White venting: Exactly same as Rheem, but more installation detail. No maximum lengths given.
For lengths greater than 5 feet, a condensate trap must be installed. Acidic water from hydrocarbon combustion will damage metal, and destroy heat exchanger inside tankless if water drips back into unit.
http://hometips.me/Tls/Venting-Bradford-White-tankless-gas.pdf

3) Copy following link for tank-type power vent tables:
Generally, the longer distance requires larger vent diameter, and there is max number of elbows and/or air-flow restrictions.
http://hometips.me/Mar/Bradford-White-Power-Vent%20-tables.pdf

4) Otherwise call Rheem/EcoSense, and add comment saying what resources they offer.

Have 75 gallon gas water heater. Can I run 90 PVC off top power vent without vertical PVC first? Have Richmond unit.


1) I believe you can immediately elbow the PVC pipe.
There is a limit for how many elbows can be used between blower and termination, and limit is determined by diameter of PVC pipe.

2) Copy following link for venting resources and typical Rheem and Richmond power vent manuals, and diameter-elbow pdf from Bradford White.
http://waterheatertimer.org/How-to-troubleshoot-gas-water-heater.html#venting

3) Richmond is Rheem. Product manual will show specifications for venting.
Product warranty is voided if installation does not follow specifications shown in manual.

I have a Bradford White water heater (model# MITW50L6LN10) that started making noise yesterday. Tonight when the family got home we started a bath for the kids and surprise surprise no hot water left in...


Probably cheaper to fix existing water heater.
The problem might be the power vent, or the power vent might be short cycling because the gas control valve is bad, or vacuum switch has gone bad.
Call Bradford White and get their recommendation for your specific model.

Bradford White is very good brand of water heater
Rheem, Richmond, GE are good.
I prefer the AO Smith, American, State, Reliance, Craftmaster. Kenmore, Whirlpool brand since air intake screen is located on bottom of unit and can be inspected and cleaned without removing burner.

What should the gas pressure be on pilot?


Copy following link to troubleshoot by type of gas control valve:
http://waterheatertimer.org/How-to-troubleshoot-gas-water-heater.html#intellivent

Bradford White posts service manuals: Both before and after introduction of ICON (Honeywell) gas control valve
http://www.bradfordwhite.com/documentation/residential/gas.asp

Don't forget to clean air intake locate under combustion parts, using instructions in service manual. Or compressed air. Ample air supply will ensure that combustion chamber does not overheat because of slowed venting of hot combustion by-product that will trip the FV system.
And remove heat trap inserts if water pressure has problem or water heater is humming or whistling

Depending on age of water heater, The air intake may need to be cleaned.
Remove combustion parts and use compressed air to clean arrestor screen located bottom of combustion chamber.

I have a Bradford White model# MITW50L6CX10, serial# TA4176718-130-131, 48 gal., gas, power vent. The vent is running constantly, and when the burner lights it burns erratically even going all the way out...


1) First suspects include Honeywell icon gas control valve, loose-or-bad wiring, and dirty burner parts.

2) MITW50L6CX10 blower number is 239-39785-00. Blower is working, but communication between blower and gas control valve are suspect.
Water heater has 6 year warranty
Water heater was manufactured January 1999.
http://www.bradfordwhite.com/findaserial.asp

3) Typical service manuals for M-1-TW-50 TTW series show how to test and replace Icon gas control.
Multimeter is required for testing.
Also shows how to clean burner parts and combustion chamber and air intake to catch up on regular maintenance.
