Hi, I'm Tim and I'm an HVAC expert here to assist you with your questions. Thanks for the opportunity to help!
This heater will be vented with class B venting vertically through the roof with an approved cap. Then use single wall venting from the appliance to the vertical stacK.
does it need to be through the roof or can i do a horizontal vent out the side wall of the garage?
No, it should go through the roof to establish a draft and be to code
it sucks because i have concrete roof tiles
ah ha, okay
so will there be a need for double wall vent material or anything crazy?
The only way you could go through the side is with a Tjernland side wall vent kit---very expensive
yikes, probably worth more than the heater itself
So class B will be double wall vent
That is for the vertical stack only
i could use a recommendation on where to purchase a vent kit
There are many places online that sell venting. Even most home improvement stores sell it
I believe this is 6 inch
yes, that appears to be correct. the vent on the heater is 6"
Yes, and it's oval coming off the draft hood, correct?
So just take the single wall and sort of "squish" it so it attaches to the outlet
so far no luck in finding an oval to round adapter though.
it's 6 3/4 wide
i will plan on that
You should be able to take the 6 inch single wall and sort of "squish" it to fit
my only other question was the wiring is cut but all there and looks to be in good shape
If you give me about 1/2 hour, I can try and see if a wiring diagram is still available. This heater is 1960's vintage!
yes, you're exactly right, it is
I'll see what I can find if you want to check back in a bit
Here is a wiring diagram
