LP-185 Rev. 3.2.15

PART 7 – 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 appliances.

Exhaust vent and intake pipes are to be piped separately, and MUST exit from the same side of the building to ensure safe, correct

boiler operation. 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.

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, severe 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.
