Figure 14 – Condensate Piping NOTE: Blow water into the condensate collector to remove any foreign matter that may block
the line.
NOTES:
1. Condensate line must be pitched at least 1/4" per foot to properly drain. If this cannot be done, or a very long length of condensate hose is
used, you must increase the condensate line to a minimum of 1” ID and place a tee in the line after the condensate neutralizer to properly
reduce vacuum lock in the drain line.
2. Plastic pipe should be the only material used for the condensate line. Steel, brass, copper, or other materials will be subject to corrosion or
deterioration.
3. NEVER install condensate lines outside. It is very important that the condensate line is not exposed to freezing temperatures or any type of
blockage. Damages due to frozen or blocked condensate lines ARE NOT covered by warranty.
4. Support of the condensate line may be necessary to avoid blockage of the condensate flow.
The condensate line must remain unobstructed, allowing free flow of condensate. If condensate freezes in the line, or if line is
obstructed in any other manner, condensate can exit from boiler tee, resulting in potential water damage to property.
When installing a condensate pump, select one approved for use with condensing boilers and furnaces. The pump should have an
overflow switch to prevent property damage from condensate spillage.
E. EXHAUST VENT AND INTAKE AIR VENT SIZING
1. The exhaust vent and intake air vent pipes are 4” for the Mod Con 300 and 500 and 6” for the Mod Con 850.
