According to the manual and the Rayak official videos all I need to do is shut off the gas , remove and allow to drain the plugs on both sides of my heater. Online though people say you should remove the pressure water valve ?
Also is it best to leave the drain plugs in or out ? The heater is left outside and I could imagine possible snow drifts ( I'm in the North east USA ) getting some snow inside the unit possibly. At the same time Would the cold cause something to crack if left sealed up... Seeking words of wisdom.. I believe my last heater died an early death due to not being properly winterized, so I am doing it myself with this new unit.
Thanks in advance for any advice !!!
ps. If anyone knows where to get the tech manual I'd appreciate it. Google'd it and found broken links.
