PART 5 – VENTING, COMBUSTION AIR AND CONDENSATE REMOVAL
The boiler must be vented as detailed in this Venting Section. Ensure exhaust vent and intake piping complies with these instructions
regarding vent system. Inspect finished exhaust vent and intake piping thoroughly to ensure all joints are well secured, airtight, and
comply with all applicable code requirements, as well as with the instructions provided in this manual. Failure to properly install the vent
system will result in property damage, severe personal injury, or death.
A. GENERAL
This boiler is certified as a “Category IV” appliance, and requires a special venting system. The vent system will operate with a positive
pressure in the pipe. Exhaust gases must be piped directly outdoors using the vent materials and rules outlined in these instructions.
Do not connect vent connectors serving appliances vented by natural draft into any portion of mechanical draft systems operating under
positive pressure. Follow the venting instructions below carefully. Failure to do so will result in substantial property damage, severe
personal injury, or death.
1. Installation should be made in accordance with the regulations of the Authority Having Jurisdiction, local code authorities, and utility
companies which pertain to this type of water heating equipment.
2. Install the venting system in accordance with these instructions and with the National Fuel Gas Code, ANSI Z223.1/NFPA 54,
CAN/CGA B149, and/or applicable provisions of local building codes.
3. This boiler must be vented with materials, components, and systems listed
and approved for Category IV boilers.
Exhaust vent and intake pipes are to be piped separately. This boiler
cannot share a common exhaust or intake with multiple appliances. Failure
to follow this instruction will result in substantial property damage, severe
personal injury, or death.
NOTE:
To avoid contamination often contained in indoor air, it is best to pipe
all intake combustion air directly to the outdoors.
NOTE:
If exhaust vent pipe system passes through an unheated space, such
as an alcove or attic, the space must be heated or the pipe must be insulated.
The insulation must have an R value sufficient to prevent freezing of the
condensate.
Failure to follow all instructions can result in flue gas spillage and carbon
monoxide emissions, causing severe personal injury or death.
Improper seating of vent pipe gaskets can cause eventual gasket failure and exhaust gas leakage. Ensure the exhaust vent pipe is
properly beveled and seated before insertion into the flue adapter. Failure to do so could result in property damage, severe personal
injury, or death.
Due to the extreme flammability of most glues, cements, solvents, and primers used to join plastic exhaust vent and intake pipes,
explosive solvent vapors must be cleared from all vent piping before start-up. Avoid using excess cement or primer, as this may pool in
the vent pipes. Vent assemblies should be allowed to cure for a period of at least 8 hours before powering a connected appliance.
Failure to follow these instructions will result in substantial property damage, s
evere personal injury, or death. It is the installers’
responsibility to understand the hazards associated with explosive solvents and take the necessary precautions to avoid these risks.
B. APPROVED MATERIALS FOR EXHAUST VENT AND INTAKE PIPE
The following materials are approved for use as vent pipe for this boiler. Failure to use approved materials could result in substantial
property damage, severe personal injury, or death.
