Frequently Asked Questions

Q. "Can I convert propane water heater to natural gas (or vise versa)?"
A. Due to possible liability, we recommend that you do not do so unless the manufacturer specifically has instructions that state that it is ok to do so.

Q. "Do you think gas water heater timers are a good idea?"
A. No, we are not aware of any gas valve that is designed to constantly be turned off and on.

Q. "How do I convert from 'Inches of water column' to PSI?"
A. 1" of water column = 0.0360 PSI and 1 PSI = 27.7612 inches of water column, we show other conversions on our info page.

Q. "How do I convert from 'CFH' ('Cubic Feet per Hour') to BTUs per hour?"
A. One cubic foot of natural gas equals approximately 1000 (one thousand) BTUs; one cubic foot of liquid propane (LPG) equals approximately 2500 BTUs. This means that a gas line's size will be able to handle more BTUs of propane than of natural gas; therefore, if you size your pipe for natural gas, you shouldn't have a problem delivering suitable BTUs for either gas type.

Q. "What is 'BTU'?"
A. "BTU" is an abbreviation for "British Thermal Unit", and is a measurement of heat that's equal to the amount of heat necessary to raise one pound of water one degree Fahrenheit at sea level. One BTU is equal to about 250 calories.

Q. "What does 45 LT stand for. I am not sure what the LT means?"
A. Years ago the LT referred to the old gas light systems. The LT is simply referring to the size of a particular fitting. For example:

      45 LT = 1 1/2" connection size
      30 LT = 1 1/4" connection size
      20 LT = 1" connection size
      10 LT = 3/4" connection size.

Q. "What is FNPT?"
A. FNPT or Female National Pipe Thread is a U.S. standard for tapered threads used to join pipes and fittings.

Q. "I can't seem to get the water in my shower hot enough. It uses an anti-scald shower valve, but the water is coming out at about 80° - nowhere near scalding. The gas valve is set high already. Do I need to replace the gas valve?"
A. The problem is most likely with the anti-scald shower valve. Anti-scald valves normally have two features - one of interest, and one most likely responsible for your problem. The one of interest is a pressure-balancing function for the shower-water delivery: once you have set the control to the desired position, any temporary drop in cold pressure will cause the valve to reduce the hot pressure in proportion. When the cold pressure has been restored, the valve rises the hot pressure in proportion, maintaining approximately the same hot-cold water mixture setting. In effect, you set the mixing ratio by turning the knob, and the valve maintains the ratio by pressure balancing. You may notice pressure changes, but the temperature changes will be slight.

The second feature, and the one which is probably responsible for the cold water, is an internal hot-limit setting for the valve. This is an internal adjustment "stop" for limiting hot flow at a preset high (hot) limit. What the installer is supposed to do is install the water system, let the water heater get to its maximum temperature, adjust the shower until the temperature is at a safe temp, and then they are supposed to adjust this high-limit stop so the shower valve can be opened no hotter. In this way a shower-taker could never get scalded - even with the hottest water from the tank. It sounds like the high-limit on your anti-scald valve is not adjusted correctly.

How to adjust the high-limit is going to vary depending on what brand/model your valve is. Due to possibilities of scalding, we recommend having a local plumber make the adjustment for you.

Q. "If I set my water heater control at 130°. At what temperature does the valve actually come on?"
A. Gas water heater controllers are designed to have a "hysteresis" effect in their start-stop temperatures. If your control valve is set at 130°, the heater will probably not come on until the water drops to 115° or so; and then heats water until it rises to over 130°. The reason for this differential is efficiency - when a burner first starts it is not fully efficient, and it is desirable to minimize the start-stop cycling of the burner.

Q. "What is a vent limiting device?"
A. Permits free inhalation for fast regulator - diaphragm response on opening cycle, but limits gas escapement to within ANSI standard should a diaphragm rupture.

Q. "Why do you only offer a 15/16" flare cap and no other 15/16" flare fittings?"
A. The 15/16" - 16 thread flare fitting is used strictly for natural and propane flexible gas connectors and not for water or with fittings used in automobiles. Up until the 1980's, 5/8" O.D. SAE (Society of Automotive Engineer) standardized flare fittings were used for natural gas and propane flexible gas connections. 5/8" O.D. SAE Flare fittings were too close in size to 1/2" iron pipe size (IPS) fittings and pipe nipples. Because of this, 1/2" IPS couplings were often being used to connect to 5/8" O.D. SAE Flare fittings and IPS nipples into flexible gas connectors which then would not properly seal causing a small gas leak.

To alleviate this type of safety issue, the American gas industry implemented the 15/16" threaded flare fitting with fine threads (16 threads per inch) to be used on 5/8" O.D. (outside diameter) tubing. The flare fittings we offer are SAE 45° flare with the exception of the 15/16"-16 gas flare fittings. The 15/16"-16 are 45° flare, but are not SAE fittings".

Q. "How can I measure my flare fitting to know if it is 15/16"-16 flare or another size?"
A. The 15/16"-16 male flare thread measures 15/16" diameter from the outside of the male threads. The flare threads have 16 threads per inch. The actual opening through the fitting is 1/2" inside diameter for the gas to flow through. Gas appliance connectors larger than 1/2" O.D. use special flare fittings designed for gas use only.
