in the spring or summer, about 50k or 60k input btuh.
Our present 169k unit is 40 years old & I'm getting a bit nervous, I'm not fond of gas explosions.
I prefer 82% efficient because the highly efficient are supposed to be touchy.
I prefer relay logic [no solid-state computer] so I can fix it myself but that may not be available.
What should I avoid?
If I get a Factory Service Manual will it be useful to me? Apparently Factory Service Manuals for cars are now useless to the DIYer.
TIA.
