Can someone tell me where the Hydronic heater valve is located for the front heating zone on a 42' Siskayou Summit, quad slide??? My front zone only blows cold air.

The valve is located on the HydroHot unit. The pumps and vlaves are found right together on the left side of the unit. When the front thermostat is calling for heat, tap each of the pumps/valves with the handle of a good sized screw driver. A pretty sharp rap will cause the stuck valve to open.
By the way. It is helpful if you sign your name and coach number to your posts.

Good luck.

I assume you have the Aquahot, rather than the Hydrohot, although in this case , the result is the same. There are no valves, as in shutting off the flow. On the top of the Aquahot there should be 6 pipes , where hose is connected to a brass fitting. These fittings are check valves, and quite often get stuck closed. That is the reason you want to rap hard on the brass fitting, to loosen the stuck check valve. All Aquahot units have the pump continuously run so that water is always flowing through the system when the heat is on. The thermostat, just turns on the fan or fans , in each zone , on a demand for heat. Before you rap on the fitting, feel the hose about a foot from the check valve, the zone with the stuck valve , will be cold(or cool ), while the others will be quite warm. After you rap on the valve , the water should begin flowing through the loop and the hose will then be warm. As a side issue , the relay switches , which are typically grey, are the relays that turn on the fans for each zone. If the fans didn't come on , these relays are the first place to check for power.
Also a reminder , that the year and model , are a good idea to post. If you have an Aquahot versus a hydrohot, or some other system , then the model of that is good , so that others with the same system, can help you. The more info , the better.
