After a month or so of initial troubles with getting the right gas supply to my new Jandy LXi heater (plumbers kept undersizing it), everything worked great. That is, until it rains.
Every time we get a decent rain, the heater won't ignite for several days, no matter how many times you try. After a few days it will start up like normal.
Makes me think water is somehow getting to where it shouldn't, but aren't these designed to be outside without a cover? I'd be hesitant to build any sort of overhang/covering because of how hot the exhaust heat is on this.
Any ideas? Thanks!
