Vent System Information

The following sections provide details related to vent pipe requirements and venting run details and
diagrams.
General Pipe Requirements & Certified Pipe Manufacturers
ORTAL appliances operate using a direct vent system and require a co-axial direct vent pipe. ORTAL
appliances must be properly connected to an approved vent system.
The pipe size required depends on the appliance size being specified:
Series 40-75 use 4x6 co-axial direct vent pipe (4-inch interior, 6-5/8"-inch exterior)
Series 90-250 use 5x8 co-axial direct vent pipe (5-inch interior, 8-inch exterior)
ORTAL is certified to be used with the following direct vent pipe manufacturers:
Olympia: Ventis line
DuraVent: Direct Vent Pro line
ICC: EXCELDirect line
BDM: Pro-Form Direct Vent System line
Selkirk: Direct-Temp System line
Proper installation, use and maintenance of pipe is determined by and can be acquired from the vent pipe
manufacturer.
If the appliance is being power-vented (a fan-assisted direct vent system for venting runs that might not
work on their own) with an ORTAL power vent, the unit will require 3x5 co-axial CVS pipe (3-inch interior,
5-inch exterior) manufactured only by DuraVent (regardless of the appliance's size), called the DuraVent:
CVS line.
For units being power vented with an Enervex power vent, standard 4x6 or 5x8 pipe is required.
NOTE: See the ORTAL Power Vent Manual for more details on Power Venting.
WARNING – Do NOT combine vent components from different pipe manufacturers. Please follow
the manufacturer's instructions for vent system installation.
Venting Requirements
When installing the venting, follow all instructions of the venting system manufacturer. For vertical and
horizontal distances, refer to the charts in the Venting Diagrams section. Maintain all clearances specified
in Vent Installation Clearances specified on the following pages. Alternatively, follow the vent system
manufacturer's instructions, provided they meet local code.

Venting Installation and Clearances

The first section of venting must be secured to the starter with a minimum of 3 sheet metal screws no
longer than ½". DO NOT use silicone to seal the sections. If sealing is required by the venting
manufacturer or local code, use Mil-Pac sealant.
When installing the venting, be sure that the vent pipe is supported by the structural surrounding and not
by the firebox. Secure the vent connection to the fireplace with a minimum of 3 self-tapping screws. Each
elbow should be strapped to reduce movement or possible disconnection. Follow the installation
instructions of the vent system manufacturer.
