CONDENSATE TRAP INSTALLATION INSTRUCTIONS
The condensate trap assembly MUST BE PROPERLY INSTALLED according to these instructions when operating the boiler.
Operating the boiler without the condensate trap assembly will cause flue gases to leak and result in serious personal injury or death.
1. Ensure all parts shown in Figure 15-1, Condensate Detail, are included with the condensate trap. If any parts are missing, DO NOT
install the trap. Replace the entire condensate assembly.
NOTE: Before installation, clean out the condensate collector with water to remove any foreign matter that may block the condensate
line.
Do not install the condensate assembly if a component is lost or missing. Replace the entire assembly. Failure to follow this warning
could result in property damage, serious personal injury, or death.
2. NOTE: The installer should fill the condensate trap with tap water prior to assembly on the boiler.
3. Slide the condensate trap adapter onto the drain tube until the holes line up with the groove.
4. Insert stainless steel lock pin to lock condensate adapter to the drain tube.
5. Connect the clear hose from the pressure switch to the hose barb.
Do not operate the boiler without the clear hose attached from the hose barb to the pressure switch. Failure to follow this warning could
result in property damage, serious personal injury, or death.
NOTE: The use of ¾" PVC or CPVC pipe are acceptable materials for condensate piping. However, use materials approved by the
authority having jurisdiction.
In the absence of other authority, PVC and CPVC pipe must comply with ASTM D1785 or D2845. Cement and primer must comply with
ASME D2564 or F493. For Canada, use CSA or ULC certified PVC or CPVC pipe, fittings, and cement. If pipe is used, deburr and
chamfer pipe to allow proper mating to the drainage assembly.
5. Run condensate drain hose to 1" PVC or CPVC drain pipe. See Figure 16.
NOTE: DO NOT cement drain hose to the PVC drainage pipe!
NOTE: To allow for proper drainage on long horizontal runs, a second line vent may be required and tubing size may need to increase
to 1". Failure to add a second vacuum break could result in condensate backup, improper boiler operation, and nuisance shutdowns.
NOTE: See Part 14, this manual, for instructions on how to maintain the condensate trap.
CONDENSATE NEUTRALIZATION
Condensate from the boiler is slightly acidic with a pH of 3.2 - 4.5. To avoid long term damage to the drainage system and to meet local
code requirements, Westinghouse recommends neutralizing the condensate with a Condensate Neutralizer Kit (Part # 7450P-212). The
neutralizer kit connects to the drain system and contains limestone chips that neutralize the pH level of the water vapor. The neutralizer
kit should be checked annually and the limestone chips replenished if necessary. When replacing the limestone chips, take care to
ensure chips are no smaller than ½" to avoid blockage in condensate piping (for piping details, refer to condensate neutralizer
installation instruction.)
