CONDENSATE DRAIN, TRAP & DISPOSAL
The HeatStation boiler
produces a significant amount of condensate. The condensate drain is under slightly positive
flue pressure; therefore the 1
"
CPVC condensate trap assembly supplied with the product must always be used. This
trap is sized and designed to create a liquid barrier to prevent flue gases from escaping through the condensate drain
into the installed space. Prior to startup or after extended periods of non-use, manually fill the trap with water before
operating the boiler.
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 boiler
’s condensate drain, at the union, prior to shipping.
2.
The condensate drain exits the flue collector at the bottom rear of the boiler.
Connect the 1" CPVC union on the trap assembly to the CPVC union on the condensate drain. Rotate the trap
assembly from the union downward, and rotate the outlet vertically to maintain a three (3) inch distance from the
hose connector to the floor.
IMPORTANT
: Do
not rotate the trap “U” bend toward the ceiling. Do not use tools to tighten the CPVC union.
Hand-tighten the CPVC union to seat the internal gasket.
3.
Connect a 3/4" ID heavy wall Vinyl tubing rated for 170ºF or higher condensate drain line, or a 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.
IMPORTANT
: Do not crimp or kink the flexible hose when routing to drain.
4.
All piping from the condensate trap to the suitable drain must remain below the top of the properly installed
condensate trap outlet.
5.
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.
6.
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.
7.
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.
