CAUTION
KEEP BOILER AREA CLEAN OF DEBRIS AND FREE OF FLAMABLE 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
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, deter-
gents,
bleaches, cleaning solvents, salts, air fresheners, paints, adhesives and other house-
hold 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 Figure 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.
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 pro-
vided on the service switch junction box
which is located at the boiler right side, to
provide power for an external condensate
pump (if needed).
