Why keep pilot light on?
Heaters prior to 1978 had "standing pilots" meaning they were on continuously, just like our water heaters still use today, since then laws enacted made a standing pilot for California illegal and the country followed Ca law.

Keeping the Pilot Light Lit . The flame should generate a micro amount of voltage which keeps the burner going. \n. \n. \nIf the burner won't stay lit the problem could b…e caused by a lazy pilot generator, dirty wire connections, high wind conditions, or even something more serious or clogged. \n. \n. \nYour best bet is to have a trained service technician from your local swimming pool company come out and give your heater the professional testing it deserves. You will find a properly tuned and installed heater will save you quite a bit these days with the high cost of fuel.
The pilot could be dirty and may be too weak to heat the thermocouple properly. Most of the time it comes down to replacing the thermocouple. ANS 2 The thermocouple cost…s less than $19 and can be changed in about 30 minutes. Best to first Shut off gas, and remove your one, then take to the store for comparison. There are 5-6 different types but all very similar. Honeywell Universal is good for many heaters. This is essentially a thin copper tube 18 -30 inches long, with a metal bulb at one end and a hollow nut at the regulator end. Many good instructions on internet about how to do it
More cost effective than what? Re-lighting it every time you want the heat to come on? That sounds ridiculous to me, unless you are using the appliance only occasionally.
There are a couple common reasons for a pilot light going out.. 1. The thermocouple is weak. This is the gold rod that must see the flame in order to keep the gas valve open.… it is a safety device that will not let the gas vavle open if there is no pilot.. 2. The pilot is dirty and has a yellow flame. If this is the case, it will have to be cleaned.. There are books on he market such as forced hot air furnace - troubleshooting and repair that show you how to repair your furnace. You can buy this at amazon.com

If your pool heater is outdoors in a high wind area, the wind might be blowing it out. In some cases you can solve this by installing an outdoor vent cap to extend the distanc…e from the end of the exhaust and the combustion chamber. Answer: try changing the "thermocoupler"( not sure of the spelling) The piolit light heats the thermocoupler. looks like a little metal rod that sits above or right next to the piolit light. when the thermocoupler is heated it produces a millivolt of electricity the power it produces is what keeps the gas vaulve open. this is a safety feature, if the piolit light goes out the gas will shut off so that the house does not fill with gas. This is why when you light the piolit you must manually hold the button in until the thermocoupler heats up. Gas appliances should only be worked on by licienced pros, don't risk the lives in your house in order to save a few bucks. http://services.Google.com/feedback/abg?URL=http://wiki.answers.com/Q/Why_does_your_gas_fireplace_go_out_after_about_2_hours_of_use&hl=en&client=ca-gurunet_wikianswers_js&adU=www.ConsumerReports.org&adT=Gas+Fireplace&adU=www.WoodstoveCombustors.com&adT=Woodstove+Combustors&adU=www.SuperiorPropane.com&adT=Propane+Appliance+Safety&done=1 . http://wiki.answers.com/Q/Why_does_your_gas_fireplace_go_out_after_about_2_hours_of_use&action=edit http://wiki.answers.com/Q/Discuss:Why_does_your_gas_fireplace_go_out_after_about_2_hours_of_use http://wiki.answers.com/Q/Why_does_your_gas_fireplace_go_out_after_about_2_hours_of_use&action=unwatch&returnto=Why_does_your_gas_fireplace_go_out_after_about_2_hours_of_use&isQRelated=1 First answer by http://wiki.answers.com/Q/User:Patrickh .

It could just need routine service. If mine goes out twice it means that a service is required, then It works fine. You are probably suffering from th…e change in standards of heating oil that occurred towards the end of 2008 when we changed from the old British Standard for kerosene to the new EU standard which drastically reduced the amount of sulphur in fuel. This has the effect of causing increased sooting and carbon build up around the fuel line and wick of an Aga or Rayburn. Over time this carbon build up restricts the flow of oil from the fuel line and eventually the oven becomes starved of oxygen. As a possible solution, I recommend the use of a fuel additive which can counteract the effects of low sulphur content and clean your carbonised Aga have a look at http://www.ecofuelplus.co.uk/#/aga-rayburn/4539905465 or Aderco 5000.
There are several reasons why a pilot light could be going on. Onereason is there could be a light breeze that is extinguishing theflame.
The pilot light burner probably needs adjustment and cleaning.
1- Spillage (down draft). 2- Defective thermo couple. 3- Not enough free air for proper combustion

The sensor wire is not sensing the flame. Check the size of the flame to make sure it is making the metal glow. If it is the ignitor box may be bad. The person asking the …question asked why it is just clicking and not firing. That has nothing to do with the flame sensor. Obviously, the pilot is not allowing gas through so the spark can ignite it. I would replace the ignitor. The gas orifice in it is more than likely clogged. The hole in the orifice is at maximum, 15 thousandths of an inch in diameter. They tend to get clogged if dirty gas gets into the system (happens often with LP(propane) but also happens with Natural Gas. If not sure of how to do this job, call an appliance service person or company. It may cost more but it will be done safely and correctly .

Keep it lit. One thing it does it keep moisture out. I turned mine off one summer trying to save a couple of bucks and had to spend about two hours cleaning the rust out.

If this is happening you need to get your furnace serviced by a qualified engineer.
The thermocouple is going bad. The thermocouple is the small tube that sits in the flame from the pilot light and goes back to the gas valve. They are easy to replace and cost… $6 to $8. For health and safety the failing part should be replaced without delay by a competent gas engineer.
\n. There is a device called a thermocouple that the pilot light flame touches. It senses if there is no flame, and turns off the gas. They go bad- have yours replaced.
