NOTES:<br />
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<br />
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<br />
reduce vacuum lock in the drain line.<br />
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<br />
deterioration.<br />
3. NEVER install condensate lines outside. It is very important that the condensate line is not exposed to freezing temperatures or any type of<br />
blockage. Damages due to frozen or blocked condensate lines ARE NOT covered by warranty.<br />
4. Support of the condensate line may be necessary to avoid blockage of the condensate flow.<br />
If using a condensate pump, select one approved for use with condensing heaters and furnaces. The pump should have an overflow<br />
switch to prevent property damage from condensate spillage.<br />
It is very important that the condensate piping be no smaller than ¾”. To prevent sagging and maintain pitch, condensate piping should<br />
be supported with pipe supports, and pitched ¼” per foot to allow for proper drainage.<br />
The condensate line must remain unobstructed, allowing free flow of condensate. If condensate freezes in the line, or if line is<br />
obstructed in any other manner, condensate can exit from the tee, resulting in potential water damage to property.<br />
