Installing Vent/Combustion Air & Condensate Drain
SECTION V - Installing Vent /
Combustion Air & Condensate Drain
Installing Vent and Combustion Air
The PRESTIGE Excellence must be vent-
ed and supplied with combustion air as
shown in the PRESTIGE Vent
Supplement, included in the boiler instal-
lation envelope. Refer to optional vent kit
instructions for additional vent installa-
tion instructions. Once installation is
completed, inspect the vent and combus-
tion air system thoroughly to ensure sys-
tems are airtight and comply with the
instructions given in the venting supple-
ment and are within all requirements of
applicable codes. Failure to comply with
the installation requirements on the vent-
ing 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 page 23.
2. Remove the retaining nut, metal washer
and rubber seals from the condensate drain
assembly. 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 retain-
ing nut with metal washer onto the
polypropylene condensate pan.
The installer may want to fill the con-
densate trap with water prior to assem-
bling on the unit.
3. Reassemble the condensate drain assembly
onto the boiler by tightening the retaining
nut with rubber seal onto the boiler.
Ensure installation of the condensate
drain assembly included the metal wash-
er. Failure to comply could result in the
trap assembly dislocating from the boiler.
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 provid-
ed, slide the compression nut and rubber
seal over the pipe
The use of 3/4” PVC or CPVC pipe is
also acceptable. If 3/4” pipe is used
deburr and chamfer pipe to allow mat-
ing onto the drain assembly.
6. Thread the rubber seal into the compres-
sion 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!
The installer may opt to using 13/16" ID
tubing in lieu of rigid piping.
