About This Honeywell Water Heater

This 40 gallon gas water heater uses a combination gas control valve and thermostat mounted low on the tank, a common design shared across many residential atmospheric vent water heaters regardless of the tank manufacturer’s own badge, since the gas control itself is frequently sourced from a component supplier rather than built in house. Similar BFG series 40 gallon tall models from this same general product family are rated between roughly 34,000 and 40,000 BTU per hour depending on the exact specification code, so the input rating stamped on the tank’s data plate is the authoritative source rather than any general BTU figure. Ignition is handled by a piezo, one hand push button spark igniter that lights a standing pilot flame, a simpler and more serviceable design than the electronic hot surface ignition used on many newer power vent water heaters. Draining a few gallons from the tank’s bottom valve periodically helps remove loose sediment before it builds up enough to insulate the burner from the water above it and reduce efficiency. Keeping the area immediately around a gas water heater clear of stored boxes or flammable materials is a simple safety habit that also makes future service calls easier to perform. Listening for a popping or rumbling sound during heating cycles is worth noting, since it often signals sediment buildup on the tank floor well before any other symptom appears. Checking that the venting above a gas water heater remains clear and properly connected is worth a periodic look, since blocked venting is a safety issue as well as an efficiency one. Testing the pressure relief valve at least once a year, by briefly lifting the lever and confirming water flows freely and then stops, catches a stuck valve before it becomes a bigger problem. Setting the thermostat to a moderate temperature, typically around 120 degrees Fahrenheit, balances comfortable hot water delivery against the scald risk and energy cost of running the tank hotter than necessary.

Most Replaced Parts on the BFG1F4034T3NOV

Thermostat and Gas Valve Problems on the BFG1F4034T3NOV

Water that runs too hot, too cold, or inconsistently usually points to the thermostat portion of the combination gas control valve rather than a heating element, since this is a gas fired tank rather than an electric one. Confirm the dial setting and pilot flame are correct before replacing the entire gas control assembly.

Pressure Relief Valve Issues on the BFG1F4034T3NOV

A pressure relief valve that weeps water, even occasionally, must be replaced immediately rather than monitored, since it is a critical safety component that vents excess tank pressure. Test the valve annually by lifting the lever briefly and confirming water discharges and then stops cleanly.

Anode Rod and Tank Corrosion Problems on the BFG1F4034T3NOV

Rusty colored hot water or a rotten egg odor points to a depleted anode rod rather than a tank leak in most cases. Inspect the anode rod every 3 to 5 years and replace it once it has corroded to less than half its original diameter to protect the tank lining.

Pilot Light and Ignition Problems on the BFG1F4034T3NOV

If the pilot will not stay lit, or the piezo igniter fails to produce a spark when pressed, check the thermocouple or flame sensing rod for proper positioning in the pilot flame before assuming the gas control valve itself has failed.

BFG1F4034T3NOV Parts FAQ

What size and input rating does this water heater have?

It is a 40 gallon, tall configuration natural gas water heater rated at roughly 34,000 BTU per hour input, with the exact figure confirmed on the tank’s data plate.

How does the pilot light get ignited on this model?

A piezo, one hand push button igniter produces the spark used to light the standing pilot flame, rather than an electronic hot surface igniter.

How often should the anode rod be checked?

Inspect it every 3 to 5 years and replace it once it has corroded to less than half its original diameter to protect the tank from corrosion.

What should I do if the pressure relief valve is leaking?

Replace it immediately. A weeping pressure relief valve is a safety component that should never be left unaddressed or simply monitored.
