CONDENSATE DRAIN, TRAP & DISPOSAL
POWER VTX

water heaters are designed for operation with normal cold inlet water temperatures of less than or
equal to100°F and produce a significant amount of condensate. The condensate drain is under slightly positive flue
pressure, so the 3/4” CPVC condensate trap furnished with the unit must always be used. This trap is sized and
designed to fill with the proper amount of condensate to create a liquid barrier to prevent flue gases escaping through
the condensate drain into the installed space.
WARNING: The trap included with this unit must be installed and maintained as described in these
instructions and must be included as part of the condensate piping system. This trap is required to keep
potentially hazardous products of combustion from continually entering the installed space where the
condensate piping terminates. Failure to properly install this trap can cause, personal injury, exposure to
hazardous materials or death.
1. The condensate trap assembly is disconnected from the water heater’s condensate drain, at the union, prior to
shipping.
2. The condensate drain exits the flue collector at the bottom rear of the water heater.
3. Connect the 3/4" CPVC union on the trap assembly to the CPVC union on the condensate drain. Ensure the
trap is rotated to a vertical position (90 degrees from the floor).
NOTE:
Additional CPVC fittings and pipe can be added to the condensate drain connection to relocate the
condensate trap assembly as long as all added parts are at the same elevation of the condensate drain
connection.
IMPORTANT
: Do not rotate the condensate drain connection toward the ceiling. Do not use tools to
tighten the CPVC union. Hand-tighten the CPVC union to seat the internal gasket.
4. Connect a 1/2" ID heavy wall Vinyl tubing rated for 170ºF or higher condensate drain line, or a PVI Condensate
Neutralization System to the barbed hose connection located at the end of the condensate trap. Alternatively,
3/4” PVC piping may be used for the condensate drain line.
5. All piping from the condensate trap to the suitable drain must remain below the top of the properly installed
condensate trap outlet.
6. Do not combine condensate drains from multiple condensing appliances into a single drain line. Route each
drain line into a drain suitable for condensate and make certain the end of the drain lines are not submerged or
otherwise blocked.
7. All condensate plumbing must be protected from freezing. Do not locate the condensate piping such that an ice
dam of frozen condensate can block condensate from leaving the outlet.
8. The condensate is only slightly acidic (3-5 PH), however, local codes may require it to be neutralized prior to
entering the drainage system. An optional, field installed, Condensate Neutralization System is available from
the factory.
