Water heater with exhaust fan attachment, no flames!


Hi,

I have come across a water heater that has an exhaust fan attachment for the vent through the side of the house. When the utility company came over to put in a new gas meter and try to light it, all they could get is the pilot to come on. I have never seen anything like this before, but it seems pretty simple (or so I would think). I think it should be something like this:

Exhaust fan turn on ->
A pressure switch activates to make sure the flue gas is exiting the system correctly ->
A safety switch is turned on (maybe?) ->
Gas valve controller turns over to allow natural gas to flow through to burner ->
Hot water

However, the water heater is still stuck at the Exhast fan turns on (step 1) and never allows gas to flow through to the burner. Maybe I need some replacement parts for the part with the side control knob and/or the natural gas control valve.. I can get the pilot to light and stay on without a problem, so there is no problem with the thermocouple or the pilot tube at all.

A couple things -
- I do feel air coming out of the crevices of the pvc pipe, so that's working
- I managed to break the threaded knob type thing with the gear socket coming out of the left, not sure if that's very important or not, but I thought it was an adjusting knob, so I tried to twist it but it broke in the middle kinda

I have attached some pics. I do not know the brand or year of the water heater since it is totally wrapped in insulation. I do know that water flows through it properly (cold at least) and that there are no leaks so far. Thanks a lot for your help. I have lit a lot of water heaters before, just not this kind unfortunately, but I would think it SHOULD be auto-lighting from this point on (the pilot does require an actual lighting flame instead of electric/push button ignition).


Thanks,
Mike

Why not take off the insulation and see make/model of heater, then you can google for lighting instructions. I doubt that insulation is providing any significant savings since it likely is foam lined tank.

To me that looks like a after market exhaust blower. The lower half of your water heater looks like a regular direct vent. I have never seen a power vent that wasn't sealed like yours is.When did you get that furnace installed.
