Valve leaking when gas bottle attached - Coleman Hot Water On Demand

You need to take that whole bottle into an authorized service dealer to have it inspected and serviced. They have special strap clamps to hold the cylinder and tools to remove the valve. They are most likely going to replace the whole valve assembly and the valves is not serviceable or available. This is due to the chances of catastrophic failure

If a gate valve: Turn the valve clockwise to turn OFF the gas.
If a ball valve: Turn the valve handle perpendicular to the valve body to turn off the gas.

Install the dryer. Attach all lines.
Turn gas on.
Using a soap/water combination, spray all gas lines to check for leaks. If any bubbles form, then turn the gas off and seal all leaks.

If you do not know how to perform these functions safely, then pay a qualified technician to prevent a gas explosion.

IF you believe there is a serious leak get out and call the fire department. If not you can use soapy water in a spray bottle to check for leaks. Note that some regulators have small releases of gas when the diaphragm moves and this is normal.

flick the little point as it may not be seating correctly. IF it still leaks attach the torch again and take it to a gas fitter and have it fixed . Remember that with gas what is in that little bottle can destroy you and your car if it is allowed to escape and ignite.

First, check that all the gas lines and flame bars are clear of any 'things' or bugs. I had a similar problem with a Webber grill and found out my problem was with the gas bottle. The new Overflow Protection Valve required on LP bottles can closed off or severly slow the flow of gas when the bottle is full and the valve is opened quickly. It will let enough gas flow to light the grill but won't let the fire get high enough to heat the grill up. Turn all the valves off on the grill and gas bottle. Open the gas bottle valve slowly then turn on the grill burner and try lighting it. If the flame is still very low try again or you have to let it burn at the low level until the OPV float drops down and the valve doesn't impede the gas flow. The best way to avoid this in the future is to not fill the gas bottle to the top when you have it refilled. Just ask the LP attendent to not fill it all the way.

Hi,
Your problem could be or probably is with the regulator...too much gaspressure...

You have a couple of questions. In order: 1. Flame may not be visible because it burns very clean. 2. When they say 'turn gas off', they actually mean 'turn gas tank off'. 3. It's not necessary to remove the tank after every use. Just make sure the gas valve is off and the entire grill and tank are covered. I do remove the tank, and store it in an outdoor shed during the winter.

Often with a big bottle, people turn the gas off and on at the big bottle and leave the grill valve open. That makes the regulator see a low pressure on its output, which is a potential leak indication. It goes into "bypass". Try turning off the tank, turning off the grill valve, and turning on the tank, then waiting 20-ish seconds before turning the grill valve on.
