Condensate Drain Requirements - UTICA BOILERS UB90-50 Installation Manual

!
Keep boiler area clean of debris and free of flamable and
combustible materials, vapors and liquids.
!
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 1/2" 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 ter-
minate exactly as shown in Figure #9 or 10 (in Combustion
Air And Vent Pipe section near center of this manual).
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.
FAILURE TO FOLLOW THE AFOREMENTIONED
WARNINGS COULD RESULT IN FIRE, PROPERTY
DAMAGE, PERSONAL INJURY, OR DEATH.

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.
Notes:
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).
