Took my Greystone out for a few days after the winter/spring cold and at the site we had only electric no city water supply. The water heater was turned on and I believe all the valves turned in the correct direction and we never got any steady hot water, hot faucet would be cold then lukewarm then hot for about 3 seconds then cold again. The propane tanks were 3/4 full and there is gas to the control valve, but no propane ignition, if there is a propane switch, I can't find it. Any help would be appreciated.
