what does the installation manual say ....it should give you that answer...ben srI am installing a Rinnai RL75iN Natural Gas Tankless Water Heater and have a question about the ventilation installation. I live in Illinois and am curious how high above the ground level I need the direct vent termination to be on the outside wall? It appears that 12" may be the answer but I'm concerned about meeting code where snow may change the requirements. Any definitive answers here? Thanks in advance!
The installation manual says, "Clearance above grade (including anticipated snow line)" is 12 inches. I'm thinking Illinois code specifies the height taking into account the "anticipated snow line". I have no idea what the anticipated snow line would be.what does the installation manual say ....it should give you that answer...ben sr
the other installation guidelines would help with that... if you need a condensation trap or if you drop the condensation out the end of pipe to outside....12" seems right ...if you get more snow than that at any given time you may need to go out and clear away exhaust pipe....ben srThe installation manual says, "Clearance above grade (including anticipated snow line)" is 12 inches.

Check with your local inspector.The installation manual says, "Clearance above grade (including anticipated snow line)" is 12 inches. I'm thinking Illinois code specifies the height taking into account the "anticipated snow line". I have no idea what the anticipated snow line would be.
again the rest of the installation provides guidlines to how you have to exit the building....if you use a condensation trap at heater pipe must slope 1/4" per foot back toward heater....then you can exit house and raise out side ...if not using trap at heater...max height off heater 5' then 1/4 " per foot falling away from heater to allow condensation to drip out the end of pipe what would be the height then......remember if condensation drips into heater it will ruin it........as a side note the installation manual says only certified installers can install this product...ben srIf I can't find an solid answer I'm thinking I will get the 39" extension to get it 4' off the ground... that has got to be high enough I would think. Interesting how hard it is to find an answer using advanced google searches. I'm usually pretty good and finding what I want.
