Furnace Intake And Exhaust Separation

The exhaust system typically uses metal venting often routed into a chimney stack to exhaust the combustion gases created in the furnace fire chamber.

Furnace intake and exhaust separation.

However these combustion gases contain residual heat that is lost through the ventilation. This is roughly the equivalent of running a bathroom exhaust fan into your furnace s combustion chamber. The exhaust pipe has two 90 degree fittings at the top of the pipe which gives a 180 degree turn and the exhaust opening is pointed straight down. Provide at least a 1 4 inch per foot upward pitch for horizontal exhaust vent piping to allow the condensate to drain back down into the furnace.

Intakes must be protected against rain and pest entry with durable rust and rodent proof materials. Supplying makeup air can help natural draft appliances by compensating the effect of the powered exhaust appliances and equipment in the house including fireplaces exhaust fans ventilation systems clothes dryers and similar appliances and equipment. Wall intakes must also be 10 feet from any exhaust fan discharge outlet unless that outlet is 3 feet or more above the intake location.

High efficiency condensing furnaces should not be vented into a chimney. This is another affordable option for the heating solution. Intakes should not be located directly above any wall exhaust or vent. Furnace intake and exhaust pvc.
