CONDENSATE DRAIN, TRAP & DISPOSAL
All Conquest
water heaters, except those applied as a booster water heater (see Section 4.3 for booster
instructions), are for operation with normal cold inlet water temperatures of less than or equal 110°F and produce a
significant amount of condensate. The condensate drain is under slightly positive flue pressure, so the provided 3/4"
PVC condensate trap 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. Attach the 3/4" PVC fitting from the union on the condensate trap assembly to the PVC pipe exiting the flue
collector located near the front of the Conquest. Additional PVC fittings and pipe can be added to the flue
collector connection to relocate the condensate trap assembly as long as all added parts are at the same
elevation. After attachment, the trap must be rotated so the offset in the pipe aims down toward the floor. Do not
rotate the offset toward the ceiling. Do not use tools to tighten the PVC union. Hand-tighten the PVC union to
seat the internal gasket.
2. 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.
3. 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.
4. 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.
5. Connect a condensate drain line or the PVI Condensate Neutralization System to the barbed hose connection,
sized for 1/2" ID heavy wall Vinyl tubing rated for 170ºF or higher, located at the end of the condensate trap. All
piping from the condensate trap to the suitable drain must remain below the highest point (top of the
condensate outlet pipe) on the properly attached condensate trap.
