Installing the Condensate Drain Assembly (Cont.)
WARNING!
Ensure the condensate drain assembly contains the plastic seated
ball. If the ball is lost or missing, do not install and replace entire
assembly with new one.
2.
Remove the compression nut (with rubber seal) from the drain outlet (Fig. 6-1).
3.
Using 3/4” x 2’ flexible PVC tube provided, slide the compression nut and rubber seal over
the pipe
NOTE
The use of 3/4” PVC or CPVC pipe is also acceptable. If 3/4” pipe
is used, de-burr and chamfer pipe to allow mating onto the drain
assembly.
4.
Thread the rubber seal into the compression nut to ease installation of the pipe to the drain
assembly.
5.
Seat the pipe onto the drain assembly and tighten the compression nut. Hand tight only!
NOTES
•
The installer may opt to use 13/16” ID tubing in lieu of rigid
piping.
•
The drain line materials must be materials approved by the
authority having jurisdiction. In absence of such authority,
PVC and CPVC piping must comply with ASTM D1785 or
D2845. The cement and primer used on the piping must
comply with ASME D2564 or F493. For installations in
Canada, use CSA or ULC certified PVC or CPVC pipe,
fittings and cement/primer.
6.
Continue the pipe from the drain assembly to a floor drain or condensate pump.
NOTE
When selecting and installing a condensate pump, ensure the
pump is approved for use with condensing boilers and furnaces.
The pump should be equipped with an overflow switch to prevent
property damage from potential condensate spillage.
7.
The Esteem boiler will typically produce a condensate that is considered slightly acidic with
a pH content below 3.0. Install a neutralizing filter if required by authority having jurisdiction.
WARNING!
The condensate drain must remain filled and unobstructed and
allow unrestricted flow of condensate. The condensate should not
be subject to conditions where freezing could occur. If the
condensate is subjected to freezing or becomes obstructed, it can
leak, resulting in potential water damage to the boiler and
surrounding area.
