Agreed the combustion should be direct piped outside, as majority of our installs we do follow this. But this customer requested 1 pipe exhaust on this particular house so we can steal the combustion from the combustion air bucket. This also passes city and manufacturer codes.
@@kookrainian what is a 'combustion air bucket'? I'm looking to have an S9V2 unit installed, but they'll need to rip holes in my basement's finished ceiling to route the intake pipe to the outside. Are you saying this is not needed? If the intake isn't routed outside, does the furnace lose efficiency? Please explain
@@gjuelz7672 all high efficient furnace require exhaust and an intake. For retrofits/replacements your old furnace may have a fresh air dump which is called a combustion air dump in the mechanical room that supplied the fresh air. If you have these you may be able to just pipe an exhaust outside. These exhaust pipe can not be shared and needs to go directly outside, most common side ways and in your case through a finished area. Best practice is to exhaust and intake, but sometimes the intake is not possible as long as there is a combustion bucket already present. Thanks Www.theheatingninja.com
@@kookrainian yes, i have a large 6" tube coming from the outside that allows fresh air directly into my basement. In fact, the tube is about 4" away from my furnace's current intake. So that's the combustion tube you're talking about? Meaning, I dont need to rip open my basement ceiling, as I have a combustion air bucket already?
@@gjuelz7672 you still require at minimum a new exhaust to go outside. Best practice is 2x pipe the system outside, exhaust and combustion. But I'm not on site and won't be able to tell you what is required for your install
Why is the intake air not routed outside!
There is a combustion air bucket for the intake.
This is up to code and city standards, and was requested by the homeowner for the 1 pipe exhaust
Intake air is not routed correctly. Should pull from outside.
