CHS Series CHS 300-399 Common Venting │Slant Fin Corp. Exhaust Vent & Combustion Air-Inlet Piping The Slant/Fin CHS 300-399 are certified as a “Category IV” boiler requiring a “Special Venting System,” designed for pressurized venting. The Exhaust and Combustion Air-Inlet must be DIRECT VENTED to the outdoors, using the venting materials outlined in Table 2-3 of this manual. Under no conditions shall the products of combustion be vented into a masonry chimney.
CHS 300-399 Common Venting │Slant Fin Corp. CHS Series 3.0 BOILER LOCATION Boiler Mounting There are two methods of mounting Slant/Fin CHS 300-399 boilers. One option is to mount the boilers directly to the wall using the wall mounting brackets provided with the boilers. The other method is to use CHS’s Floor Stand (P/N 818 169) and Floor Stand Twinning Kit (P/N 818 220). Mounting the boilers requires a minimum of two people to lift the boilers into place.
CHS 300-399 Common Venting │Slant Fin Corp. CHS Series Floor Stand Mounting Method CHS’s Floor Stands and Twinning Kits are designed with precise height and spacing for assembling the Common Vent Manifold System. One Twinning Kit is required to joint two Floor Stands together; two Twinning Kits are required to join three Floor Stands together.
