• Combustion air must be clean outdoor air. Do not take 

combustion air from inside structure because that air 

is frequently contaminated by halogens, which includes 

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. Typical areas 

of contamination include dry cleaning facilities, swimming 

pools, beauty shops, new building construction, air 

conditioning equipment. For example combustion air 

intake near swimming pool chemicals will damage any 

condensing boiler.

• 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. 

• Follow instructions in this manual for combustion air and 

vent piping termination.

• Use of concentric vent termination refer to Figures 10, 11 

and 12 for proper setup.

• Vent connections serving appliances vented by natural 

draft shall not be connected into any portion of mechanical 

draft systems operating under positive pressure.

• Fully support all vent piping. Use hangers at intervals to 

prevent pipe from sagging.

Fire, explosion, asphyxiation hazard.  Solvent 

cements are combustible.  Keep away from heat, 

sparks, or open flame. Use only in well ventilated 

areas. Avoid breathing in vapor or allowing contact 

with skin or eyes. Improper installation could result 

in death or serious injury.  Read this manual and 

understand all requirements before beginning 

installation.
