You will need to find the shutoff valve at your gas meter. With a big wrench turn it 1/4 turn this will cutoff the gas to you house completely. Now you can remove the old valve and install the new one safely. There may be a bit of residual gas pressure in the piping of the house. But make sure that it stops before removing the valve completely. Use a good pipe dope on the threads on the pipe before installing the new valve. Turn on the gas at the meter again and spray the threads at the gas valve with soapy water to check for leaks. If the soapy water makes bubles you have a leak. Turn off the gas again and tighten the valve down more or reinsatll the valve with fresh pipe dope.

How do I install my hot water heater?


Youtube offers many videos of the water heater installation. Drain first with a garden hose. after turning off water and unplugging electric or shut off gas.

If changing to a tankless, remember they often require a larger vent pipe to the roof. 4" usually, not the 3" for tank water heaters. Local building codes may require a permit and a larger Gas feed pipe.
Also if you're going to use the old Pressure Relief Valve DO NOT test the valve by activating the little lever. Once used over time their internal seals weld onto the closed seat and tend to rip and leak if you test the valves function. Replace with new ( $15) if it's been operated. Most plumbers now use Braded Feed Lines from/to the Water sources, making future replacements easier. You might find the replacement Tank is not the same geometry as the old one, having longer braided feed lines helps when they are on opposite ends of the tank top and the original feed lines are copper and wont reach the new tank pipes or the tank gas starter door is on the back side requiring you to rotate the tank 180. If you're changing size, measure the width and height. It might not fit the old installation.

Gas Control Valve replacing!


Shut off the water and gas to the heater. Drain the heater. Disassemble the gas line to the heater starting at the Union and working to the gas control. Disconnect thermocouple, burner and pilot tunes from the bottom of the old gas control. The old control will screw out of the front of the heater. Grab the entire housing of the control and twist counterclockwise to remove. Perform new gas control install and connections in reverse. Remember to apply at least 4 wraps of Teflon tape on all threads before assembly. (Teflon paste may be used) Do NOT put any sealant on the thermocouple,burner tube or pilot tube connections (these are compression connections, make them fairly snug.) upon completion, fill heater, turn gas back on relite and check for water or gas leaks

Used, Reliance 805 is power vent gas
10 year old water heater that is newly installed.
Unknown gas control valve.
I'm not a fan of installing old power vent water heaters.
Usually these things are so expensive that old one is only replaced when it fails.

120Volt Outlet must have correct polarity and unit must be grounded between ground prong on cord to manifold tube connected to bottom of gas control valve. Test for continuity with multimeter.

Is this an early FV model with air intake located on bottom?
If air intake is clogged with dust, then combustion chamber overheated and tripped FV system. The older heaters need replacement parts and new gas control valve, or entire heater must be replaced.

Replace gas control valve.

It might make more sense to sit the heater on some inexpensive concrete blocks (like stepping stones, purchased at a local hardware store) to raise is off the floor. The heat is causing the cool moist air under your house to condense under the vinyl mat. You could shim it off the floor with most anything that is non combustible and as little as an inch would probably give you enough clearance to stop the problem. Hope this helps!

Floor heater won't light


At the gas valve on the furnace, jump the two connections where the thermostat wires attach to, I think TH and TP may be marked on terminals. If it lights, you have bad wire(s) going to thermostat. If it still refuses to light, you may be looking at a new gas valve.

A.O.Smith water heater relief valve letting out water


You just need a new pop off valve $10-$15 dollars. Unscrew the old one on top of the heater, put some teflon tape on the new one and screw it in place. Being that the house is for sale I would probably have a licensed plumber do it just to protect my self from any liability. Also most state codes require that pipe to terminate in a floor drain, most home inspectors will catch that. If it doesn't I would have him do that also.

Hope this helps-please rate

These old units have a simple gas valve and a separate regulator. Your best bet may be to replace the gas valve to something more modern. Trouble shooting this most likely be a waste of time, as parts probably aren't available, other than the thermostat. by-pass it, (connect the 2 wires together) and see if it comes on. The blower shouldn't stop the burner to come on. Sounds like the gas company doesn't want to crawl under there to light it.
