System Design and Installation Guides

Before laying out a gas vent system for any gas appliance, the installer should first consult the local code and the appliance manufacturer’s installation requirements. Only then should you pick components and design the vent system. Selkirk offers pipe sizes and adjustable components to provide maximum design flexibility.

TYPE B
Selkirk Type B Gas Vent (Sizes 10″ through 30″ round) may be installed with the following minimum clearance to combustibles:

• US clearance to combustible all diameters = 1″
• Canada clearance to combustibles: 10″- 24″= 1″ 26″- 30″= 2″

To graphically illustrate the use of Model R components in typical installations, we offer the diagrams on the next page.
To guide you in these and other installations, the following general rules should be followed.

1. Provide adequate air supply. Remember, you must meet local code minimum requirements for both combustion air and draft hood dilution air.
2. Attach vent to appliance’s draft hood or attachment collar with sheet metal screws and terminate the vent at least 5 feet above the draft hood. See Gas Vent Termination Table on page 9 for required height above roof.
3. One gas vent may serve more than one gas appliance. Prudent advance planning (see diagrams on next page) can save you time.
4. Keep offsets and lengths of laterals to a minimum to reduce vent resistance.
5. Strap the vent securely in position, always maintaining appropriate clearance to combustibles. Firestops should be used where vents pass through floors, walls, or ceilings.
6. The vent termination must be securely guyed or braced if it extends more than 5 feet above the roof.
7. For long lasting durability and better appearance, all vents exposed to the weather (except caps) should be painted.
8. Vents installed outside of the structure reduce venting action. Such installations are not recommended.

Typical Selkirk Type B Gas Vent Installations

INTRODUCTION

Selkirk Model R Large Diameter Type B Gas Vent was designed with the installer in mind and to endure the elements. Lightweight construction with a small footprint, Selkirk Model R will deliver when space is tight but performance is essential. Easy to connect and assemble, you can count on a secure fit when installing Selkirk Model R.
Selkirk’s Model R Type B Gas Vent is listed and approved by UL for residential, commercial, and industrial applications. Selkirk Model R provides a continuous passageway from a Category 1 gas appliance, such as water heaters, boilers, and furnaces, to the termination of the vent above the roof of a structure.
Some of the safety features within Model R includes:

• Double wall construction with ½” air space
• Clearance to combustible standards of:
• 1″ in the United States for all diameters
• 1″ in Canada for diameters 10″ to 24″
• 2″ in Canada for diameters 26″ to 30″
• Galvanized steel outer wall construction for exceptional corrosion resistance *exterior applications must be painted in Canada*
• Aluminum inner wall construction to keep flue gases hot

Model R is to be installed in single and multi-story buildings in accordance with the following Natural Gas & Propane Codes:
USA: NFPA 54
CANADA: CAN/CSA B149.1 & .2
Selkirk Model R is accepted by: AGA, NFPA, HUD, NBC, UBC

Why Selkirk Model R?
Lightweight
We keep the connections clean to reduce the weight of the pipe making installation a SNAP (twist-snap that is).

Smaller footprint
Clean connections coupled with a ½” air space tighten the diameter of the pipe to create a solid connection suitable for tight spaces.

Easy to connect
Model R’s snap lock coupling system creates a secure, confident connection. Simply align the seams, twist, and SNAP ­ ready to go!

Backed by an exceptional warranty
We are so confident in Selkirk Model R’s ability to satisfy, we’ve backed it by the industry’s finest warranty, the Smart Choice Warranty.

Lengths

ROUND PIPE

Adjustable Length

Used in combination with a straight length of pipe to assure an exact length can be achieved.

Elbow and Tees

45˚ ELBOW

• Elbows are used to offset installation to avoid obstructions such as rafters and joists
• Size 10″ through 14″ adjust easily from 0° to 45°
• Sizes 16″ through 30″ are non-adjustable
• See the Gas Vent Offset Table on page 14

TEE

• A tee transitions a system from horizontal to vertical orientation.
• Provides easy access for inspection and maintenance.
• Tee Cap sold separately.
• Branch and trunk diameters of the standard tee are the same size.

• The Tee Cap is used to close the bottom or branch of the Tee.
• Removable for easy system maintenance.

TEE CAP

Rain Cap

• Used as a ventilation cap as well as a Type B gas vent termination.
• Protects against wind conditions that can cause gases to spill back into the structure.
• Reference the Gas Vent Termination Table on page 14, for minimum height requirement above the roof line.

MODEL C UNIVERSAL CAP

Connector and Increaser

DRAFT HOOD CONNECTOR

• Connects Type B gas vent directly to an appliance draft hood.
• Connects single wall connector pipe to B vent.

INCREASER

• The increaser is used to increase the vent size
• The maximum increase is 4 sizes

Supports

SUPPORT BRACKET ASSEMBLY

Hangers provide support and resupport for offsets and horizontal.

For diameters larger than 12″ use Plumber’s Strap.

VENT COLLAR 

The vent collar provides a cover for rough wall openings.

WALL THIMBLE

• Used to install pipe through an interior wall
• Maintains proper clearance from combustibles
• The wall thimble adjusts for various wall thicknesses from 4″ to 7″

SUPPORT PLATE

• The support plate is designed to provide strength and durability for supporting large size pipe sections
• Serves as a firestop
• Supports up to 30′ of pipe

Flashings and Storm Collars

STANDARD FLASHING

• Fits flat to 6/12 pitch roof
• Built with double-seamed construction for protection from leakage

TALL CONE FLASHING

• Used on flat roofs in snow-packed areas to reduce chances of snow covering the vent
• The flashing with a tall cone fits flat to 1/12 roof pitches

ADJUSTABLE STORM COLLAR

• Used to provide weather strip seal to pipe above flashing
• Seal the inner edge with sealant against pipe

Tables

GAS VENT TERMINATION TABLE

Caps in 10″ through 12″ sizes may be installed in accordance with the Gas Vent Termination Table if the vent is at least 8′ from any vertical wall.
For installation of caps 14″ and larger, or for caps that are less than 8′ from a vertical wall, the cap is to be located no less than 2′ above the highest point where the vent passes through the roof and at least 2′ higher than any portion of a building within 10′.

10″ and 12″ Diameter Caps

GAS VENT OFFSETS TABLE

Note: The vertical rise can also be closely estimated by adding one “A” and one “B” dimension to Maximum Offset figures. (See page 8 for “A” and “B” dimensions of Round Adjustable 45° Elbows.)
This table is used to determine the offset produced by two Selkirk 45° elbows set at the maximum angle of 45°. Also shown are the offsets produced by introducing various lengths between the two elbows.
