SECTION V - Installing Vent / Combustion Air & Condensate Drain
Installing Vent and Combustion Air
DANGER
The PRESTIGE must be vented and supplied with combustion air as shown in the
PRESTIGE Vent Supplement, included in
the boiler installation envelope. Refer to
optional vent kit instructions for additional
vent installation instructions. Once installation is completed, inspect the vent and
combustion air system thoroughly to ensure systems are airtight and comply with
the instructions given in the venting supplement and are within all requirements of
applicable codes. Failure to comply with
the installation requirements on the venting and combustion air piping will cause
severe personal injury or death.
Installing Condensate Drain Assembly
1. Locate the condensate drain assembly and
install as shown in Fig. 14.
NOTICE
The installer may want to fill the condensate trap with water prior to assembling
on the unit.
3. Slide the rubber seals from the condensate
drain assembly over the heat exchanger condensate drain nipple. Connect the condensate
drain assembly to the retaining nut and tighten.
WARNING
Ensure the condensate drain assembly
contains the plastic seated ball. Do not install the condensate drain assembly if the
ball is lost or missing, replace the entire
assembly.
4. Remove the compression nut and rubber
seal from the drain outlet.
5. Using 3/4” x 2’ flexible PVC tube provided,
slide the compression nut and rubber seal
over the pipe
2. A metal washer must be installed when installing the condensate drain assembly. On
all models except the Solo 399, the metal
washer must first be cut using a pair of diagonal cutting pliers to make it into a split
washer. Insert the metal washer into the retaining nut and screw onto the condensate
drain assembly without rubber gaskets. Use
the condensate drain assembly as a tool to
press the retaining nut with metal washer
onto the polypropylene condensate pan. Unscrew the condensate drain assembly and
proceed to the next step.
WARNING
Ensure installation of the condensate drain
assembly included the metal washer. Failure to comply could result in the trap assembly dislocating from the boiler.
NOTICE
The use of 3/4” PVC or CPVC pipe is also
acceptable. If 3/4” pipe is used deburr
and chamfer pipe to allow mating onto
the drain assembly.
6. Thread the rubber seal into the compression
nut to ease installation of the pipe to the
drain assembly.
7. Seat the pipe onto the drain assembly and
tighten the compression nut. Hand tight
only!
NOTICE
The installer may opt to using 13/16" ID
tubing in lieu of rigid piping.

NOTICE
The drain line materials must be an approved material 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.
8. Continue the pipe from the drain assembly
to a floor drain or condensate pump.
NOTICE
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.
9. The PRESTIGE 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.
CAUTION
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.
