SECTION V - INSTALLING VENT
/ COMBUSTION AIR &
CONDENSATE DRAIN
5.1 Installing Vent and Combustion Air
The PRESTIGE Excellence must be vent-
ed and supplied with combustion air as
shown in the PRESTIGE Excellence 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.
5.2 Installing Condensate Drain
Assembly
1. Locate the condensate drain assembly and
ensure the metal washer is installed as
shown in Fig. 11 on page 23.
The installer may want to fill the con-
densate trap with water prior to assem-
bling on the unit.
2. Install the condensate drain assembly on the
boiler condensate drain by pushing the con-
densate drain assembly up until it stops.
3. Tighten the condensate drain assembly
retaining nut with rubber seal.
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 condensate drain assembly
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 use 13/16" ID
tubing in lieu of rigid piping.
