Combustion air and vent pipe connections must terminate together in the same atmospheric
pressure zone, either through the roof or sidewall (roof termination preferred). See Fig.9 & 10
for required clearances.
CAUTION
KEEP
BOILER
AREA
CLEAN
OF
DEBRIS
AND
FREE
OF
FLAMMABLE
AND
COMBUSTIBLE
MATERIALS,
VAPORS
AND
LIQUIDS
WARNING
When vent pipe is exposed to temperatures
below freezing,
such as when it passes through
an
unheated
space or when a chimney
is used as a raceway,
vent pipe must be insulated
with
l/2"Armaflex
or equivalent.
In extreme cold climate areas, use ¾ "Armaflex
or equivalent.
Combustion
air must be clean outdoor air. Combustion
air must not be taken from inside structure
because that air frequently
is contaminated
by halogens,
which include fluorides,
chlorides,
phosphates,
bromides
and iodides.
These elements are found in aerosols,
detergents,
bleaches,
cleaning
solvents,
salts, air fresheners,
paints, adhesives
and other household
products.
Locate combustion
air inlet as far away as possible from swimming
pool and swimming
pool pump
house.
All combustion
air and vent pipes must be airtight and watertight.
Combustion
air and vent piping
must also terminate
exactly as shown in Fig.9 or 10.
Vent connections
serving appliances
vented by natural draft shall not be connected
into any portion of
mechanical
draft systems operating
under positive pressure.
Solvent cements are combustible.
Keep away from heat, sparks,
and open flame. Use only in well
ventilated
areas. Avoid breathing
in vapor or allowing contact with skin or eyes.

F. CONDENSATE
DRAIN REQUIREMENTS
Condensate
drain line to be pitched down to floor drain at a minimum
of ¼ "per foot. An external
condensate
pump (not furnished)
may be used if floor drain is not available.
The condensate
pump
must be designed
for flue gas condensate
application
NOTE:
1. Condensate
trap is built into the boiler, an external
trap is not required
and should not
be used.
2. Wood frame or blocks may be used to raise the boiler to maintain drain pitch or to be
above external
condensate
pump reservoir.
3. There is a 115 volt AC receptacle provided
on the service switch junction
box which
is located at the boiler right side, to provide power for an external condensate
pump
(if needed).
