PART 7: VENTING, COMBUSTION AIR & CONDENSATE REMOVAL

DANGER

Munchkin Boiler must be vented as detailed in Venting section Part 7. Ensure the exhaust and intake piping comply with these instructions regarding vent system.

Inspect finished combustion air intake and exhaust piping thoroughly to ensure all joints are well secured and airtight and comply with all applicable code requirements, as well as with the instructions provided in this manual.

Failure to provide a properly installed vent system will cause severe personal injury or death.

b. Non Foam Core CPVC (Chlorinated Polyvinyl Chloride) Pipe conforming to ASTM D-1785.

c.Non Foam Core ABS (Acrylonitrile- Butadiene- Styrene) Pipe conforming to ASTM D3965 Class 3-2-2-2-2.

WARNING

Do not use Foam Core Pipe in any portion of the exhaust piping from this boiler. Use of Foam Core Pipe may result in severe personal injury, death, or substantial property damage.

A.INSTALLING EXHAUST VENT AND INTAKE AIR VENT

WARNING

This vent system will operate with a positive pressure in the pipe. 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 may result in severe personal injury, death, or substantial property damage.

B.GENERAL

1.Install the boiler 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.

2.This boiler is a direct vent appliance and is listed as a Category IV appliance with Underwriters Laboratories, Inc. VENT AND INTAKE AIR PIPE

C.APPROVED MATERIALS FOR EXHAUST VENT AND INTAKE AIR VENT

1.Use only Non Foam Core venting material. The following materials are approved for use as vent pipe for this boiler:

a.Non Foam Core PVC (Polyvinyl Chloride) Pipe conforming to ASTM D-1785.

2.Cellular foam core piping may be used on air inlet piping only. Never use cellular foam core material for exhaust vent piping.

D.EXHAUST VENT AND INTAKE AIR VENT PIPE LOCATION

WARNING

Both exhaust and intake air vents must exit from the same side of the building to assure correct appliance operation.

1.Determine exhaust vent location:

a.The vent piping for this boiler is approved for zero clearance to combustible construction.

b.See illustration within this section of clearances for location of exit terminals of direct-vent venting systems.

c.This boiler vent system shall terminate at least 3 feet (0.9 m) above any forced air intake located within 10 ft (3 m). Note: this does not apply to the combustion air intake of a direct-vent appliance.

d.Provide a minimum of 1 foot distance from any door, operable window, or gravity intake into any building.

e.Provide a minimum of 1 foot clearance from the bottom of the exhaust above the expected snow accumulation level. Snow removal may be necessary to maintain clearance.
