B. 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 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. 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. 15
