24. Venting

Model LDAP heaters are certified as Category III heaters.

WARNING: Each heater requires its own individual vent pipe run and vent cap. Manifolding of vent runs can cause recirculation of combustion products into the building. Failure to comply could result in severe personal injury or death and/or property damage.

Venting must be in accordance with local codes and the National Fuel Gas Code Z223.1 or CSA B149.1 and B149.2, Installation Code for Gas Burning Appliances and Equipment. Local requirements supersede national requirements.

These power-vented heaters are designed to operate safely and efficiently with either a horizontal or vertical vent. Comply with the specific requirements and instructions.

If this heater is replacing an existing heater, be sure that the vent is sized properly for the heater being installed and that the existing vent is in good condition. A properly sized vent system is required for safe operation of the heater. An improperly sized vent system can cause unsafe conditions and/or create condensation. Do not vent into an existing gravity vent or chimney.

Installation should be done by a qualified agency in accordance with these instruc- tions. The qualified service agency installing this system is responsible for the instal- lation.

Venting Requirements

1) Type of Vent Pipe

The type of vent pipe is determined by whether the vent is horizontal or vertical.

Horizontal • Vent pipe approved for a Category III appliance, OR

2)Vent Pipe Diameter and Length

• Appropriately sealed 26-gauge or heavier galvanized

 

 

steel or equivalent single-wall pipe

Vertical

•

Vent pipe approved for a Category III appliance, OR

 

•

Appropriately sealed 26-gauge or heavier galvanized

 

 

steel or equivalent single-wall pipe

OR, if at least 75% of the equivalent length of the vent run is vertical

• Double-wall (Type B) vent pipe

Vent pipe diameters and maximum vent lengths in the table apply to both Horizontal and Vertical vents. Add all straight sections and equivalent lengths for elbows. The total combined length must not exceed the Maximum Vent Length.

•Use only one diameter of vent pipe on an installation.

•Minimum vent length is 3 feet (1M).

•Minimum of 1 ft (0.3M) of vertical vent required on venter outlet before installing an elbow.
