VENTING
PART 5: VENTING, COMBUSTION AIR & CONDENSATE REMOVAL
(CONTINUED)
the condensate line is not exposed to freezing temperatures, or any other type of blockage. Plastic
tubing must be the only material used for the condensate line. Steel, brass, copper or others will be
subject to corrosion or deterioration. A second vent may be necessary to prevent condensate line
vacuum lock if a long horizontal run is used. Also, an increase in pipe size may be necessary to drain
properly. Support of the condensation line may be necessary to avoid blockage of the condensate
flow.

OF BLOCKAGE.
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 OTHERS WILL BE
SUBJECT TO CORROSION OR DETERIORATION.
3. IT IS ALSO VERY IMPORTANT THAT THE CONDENSATE LINE IS NOT EXPOSED TO FREEZING TEMPERATURES, OR ANY OTHER TYPE
NOTES:
CAUTION
The condensate line must remain unobstructed, allowing free flow of condensate. If
condensate is allowed to freeze in the line or if the line is obstructed in any other manor,
condensate can exit from the water heater tee, resulting in potential water damage to
property.
NOTICE
Use materials approved by the authority having jurisdiction. In the absence of other
authority, PVC and CPVC pipe must comply with approved venting material chart in
Section 5-C.
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.
Condensate from the Phoenix will be slightly acidic (typically with a pH from 3.2 to 4.5).
Install a neutralizing filter if required by local codes.
