Is this gas valve for a furnace on or off?
I would guess on. Generally the valves follow the same orientation as the handle.
Can't you "push" that valve in to indicate its on?
I know that's how my fireplace's works.
Yes but I can turn so that the 'on' text is on the bottom or top.
I would guess ON also. Generally the raised portion points the same direction as the pipe entering the valve for ON.
See my reply above
The valve for my furnace you don't have to push in to turn from OFF to ON, for my water heater I do. My furnace is only two years old. If you do have to push it in to move from one position, then you would be moving from OFF to ON, so easy to figure out.
I don't have to push in
Just above the words "off" is that a little arrow pointer? If it is, i would guess "off". Which way can you manipulate the valve (clockwise or counter clockwise)?
No arrow. Here's another picture
I agree with @CyCloned can't you just check the pilot light?
For 1/4 turn valves, the conventional operation is the valve is open/on when the handle is parallel to the pipe and closed/off when its perpendicular. So from that second photo, I'd guess its it's on.
But does it seem like you have to turn it a 1/2 turn to go from on/off? It looks like a 1/4 turn valve but hard to know for sure from a picture. Based on the diagram symbol to the left, I'd say having 'off' point left is off and 'on' point up is on.
I went to 4.5 years of engineering and have watched a lot of Youtube. The key to a valve is that if it doesn't work one way, turn it the other.
Seriously though, it looks to be 'on' to me in the second picture. No pilot light?
Is that another valve of some sort in the elbow at the top of the picture?
That's the problem, I don't think it's lighting regardless of which way I have the valve. Its automatic ignition.
It's not 1/4 turn. 1/2 turn so 'on' text could be up or down. Maybe both are open?
Just turn your thermostat up and see if the furnace works. If not.......try the other position. Most will not fire if there is no pressure to the valve.
Have you googled the furnace manufacture and model number for a manual?
