It very well may be that circuit control board has malfunctioned. In which case you should receive a series of blinks from a red blinking light. The number of blinks, determines what the problem is.

These, generally are very dependable high efficient wall heaters.

In case you have misplaced your Owners Manual, I have provided a link to it. You can download and print for future reference if you like.

What type of hammer arrestor do I buy to fix banging pipes after installing a new Moen posi-temp cartridge?


Banging pipes are a result of improper piping support. If the piping is secured, the banging will stop. If your only option is to install chambers for water hammer, any will do. Their only purpose is to hold air.

Noisy water pipes when neighbours use water


Install air chamber to cushion sudden-stop of flowing water.
Water flow coming to sudden stop is called water hammer, and will bang pipes, but also loosen plumbing joints, causing leaks.
http://waterheatertimer.org/How-to-troubleshoot-electric-problems-with-water-heater.html#bang
http://waterheatertimer.org/images/Flow-rates-water-hammer-600.jpg

Air chamber has to be vertical, and about 18" long, with cap on top.
By code each Hot and Cold line at each tap will have air chamber located behind the wall. So there are two air chambers at each tap.

In your case, you can probably add air chamber to your Hot and Cold lines and solve problem for both dwellings.

Water hammer is caused because water does not compress like air.
So when long column of water suddenly stops... the whole pipe-full of water comes to sudden halt... and that water could weigh 1-1/2 pounds ... and just like a hammer head moving, the weight of water bangs the pipes to dissipate energy, causing noise.

09 yamaha r6-Steam or white smoke on start up lasts for about 3-5 minutes


Hi, 123gevans your instrument gauges and lights can alert you to most electrical and engine issues they can not warn you about failed engine gaskets or seals so your engine has to resort to old fashion alert methods of colored "SMOKE SIGNALS" here is a breakdown of their meaning:
1. COLORLESS OR SLIGHTLY BLUE SMOKE on start-up means your air/fuel mixture is at the right composition and everything is well burnt in your combustion chamber.
2. BLUE SMOKE on start-up is usually caused by failed valve seals dripping oil into the combustion chamber when the engine is not running.
3. YELLOW OR BROWNISH SMOKE at start-up means your air/fuel mixture is too lean. Too lean means that there is low fuel but high air mixture in your combustion chamber.
4. WHITE SMOKE on start-up may be caused by a blown head gasket allowing coolant to enter the combustion chamber and may start dripping out of the exhaust pipes or mufflers. Smoke while riding is usually caused by worn out or damaged valves, seals, guides, pistons, rings, or cylinder walls.
5. BLACK SMOKE on start-up is usually caused by too much fuel in the combustion chamber this can be due to air/fuel mixture adjustment too rich, accelerator pump improperly adjusted, faulty choke/enrichner or not in the off position, air filter dirty and clogged, faulty carburetor float needle and seat, pilot jet too large, fuel injectors leaking, smoke while riding is usually caused by the main jet being too large or a damaged carburetor.
It should be noted that aggressive or abnormal throttle operation will cause these conditions to manifest themselves exponentially.

There is black "dust"all over


the dv 215 uses no room air for the combustion. it is called a sealed combustion unit all combustion air and vent gases are outside of the building. look at the vent cap outside. is it black? if not unit is most likely working ok. if it is black you need to have it checked. so unless the unit has been damaged you should be getting no air from the combustion into your room.

Martin lp gas heater has recently begun to make loud metallic bangs during use. This heater is approximately 15 years old. Can these metal banging noises be a sign of something potentially dangerous? ...


If you can inspect the combustion chamber for cracks it may be a good idea. To get rid of the banging, put a dent in the metal combustion chamber.

MY WILLIAMS WALL GAS HEATER MAKES A LOUD BANG AFTER A FEW MINUTES ON


Question, is this bang a metal sound or like a small poof of a gas burner? If it is a metal "bong", it is the heat exchanger expanding. You could hit the combustion chamber with a hammer causing a dent (really) and it may take the noise away. If it is a "poof", it should be looked at by a technician.

B vent configuration of direct vent propane heaters


Yes, the design of the combustion chamber is limited at how much fresh air and combustion air can enter it. If you lengthen the venting, you will be causing more restriction and there will not be enough natural air movement to make it work. It will start, run for a minute or two and poof out. Not to mention you will be circumventing it's UL rating and if you sell your home with it installed, you are liable for any fatality or damage. Do you want to risk that? Don't even think of doing it! There are "Box" heaters out there sized from about 5,000 Btu's on up to 100,000 Btu's. Check the web.
