COMBUSTION AIR - See Figures 5 and 6
1. The boiler may be operated with inside or outside
air.
2. Refer to combustion air piping drawings in this
section of this manual for proper outside air
installation details.
3. Combustion air conduit can be galvanized smoke
pipe, PVC, CPVC, or flexible aluminum conduit.
4. The maximum air inlet length is fifty (50) equivalent
feet. Air inlet length is equal to the total length of
straight pipe plus the equivalent length of fittings.
Consult conduit manufacturer for equivalent length
of fittings and pipe.
5. Consult intake pipe manufacturer's instructions
for proper method of sealing vent pipe sections
and fittings. Do not use other adhesives or sealants
except as expressly permitted by the vent pipe
manufacturer's instructions.
WARNING
Do not reduce size of air intake pipe.
Read, understand and follow combustion air
instruction restrictions contained in the Pre-
Installation instructions of this manual.
6. Air intake termination must be located at least
twelve (12) inches above grade plus the expected
snow accumulation.
7. Boiler may be installed with vertical venting and
sidewall combustion air inlet or visa versa.
8. The air intake pipe must be adequately supported
with straps or supports no less than five (5) feet
apart. The completed air intake pipe system must be
rigid and able to withstand impacts without collapse.
CAUTION
Dirty, contaminated or dusty air used for
combustion will decrease the useful life of
the boiler air filter. Use outside air if inside
air quality is questionable. Use outside air if
the boiler is installed in manufacturing plants,
laundries, dry cleaners or other locations with
heavy particulates in the air.
WARNING
Do not locate air intake where petroleum
distillates, CFCs, detergents, volatile vapors
or any other chemicals are present. Severe
boiler corrosion and failure will result.
Thermal Solutions does not warrant failures
caused by contaminated air.
Do not locate air intake termination where
natural convection or wind conditions may
cause the boiler exhaust gases to be drawn
into the air intake.
