This is the last part on the series for the Rinnai RUR unites. This is the three different ways to properly vent this type condensing unites.
You have the three different sizes of concentric horizontal venting the 8' the 11.5" and there is also a 21" one
You can also vertical vent the unit with concentric venting but that's going to be a totally separate video.
The 2" PVC venting is the other option. (PLEASE REMEMBER THE PIPE NEEDS TO BE SCHEDUAL 40 PVC RED LETTER THATS FOR PRESSUER)
remember to install the two screens supplied with the tankless to secure the screens into the fittings.
a slight pitch outside is always good to get any condensate to run out of the pipe.
65' of total vent run and you need to minus 6 feet per elbow and 3 feet per 45*
Please follow the installation manual for all the distances need for proper installation of the venting and fresh air intake from windows, doors ect.
If you have a questions please e-mail me at economyplmbg@aol.com
I hope you enjoy this video and series.
Please hire a licensed plumber certified in level 3 Rinnai training and to follow all state and local codes. Please file a permit with your local building dept.
Thanks,
Mike
