Selkirk RV Installation Instructions

1. GAS VENT DESIGNATIONS/TYPES OF APPLIANCES
Selkirk Canada Corporation Type B Gas Vent parts LISTED
and produced under the Factory Inspection and Follow-up
program of Underwriters' Laboratories, Inc. carry the LISTING
MARK illustrated here. Type B Gas Vent has been tested, and listed using all
of the supports, firestop, etc., described herein. Deletion or modification of
any of the required parts or materials may seriously impair the safety of your
installation, and void the certification and or warranty of this vent. It is of the
utmost importance that this vent be installed only in accordance with these
instructions.
Type B Gas Vent is designed for venting of listed (L.P. or Natural) gas appliances
equipped with draft hoods and other listed gas appliances specified for use
with Type B gas vent producing flue gas temperatures not in excess of
245°C (470°F). DO NOT USE Type B Gas Vent for Category II, III or IV gas
appliances, or for any gas appliance which requires either a pressure-tight
or liquid-tight venting system.
All sizes of Selkirk Type B Gas Vent may be used in single and multistory
buildings. All Type B Gas Vents may be used for both individual and multiple
appliance venting.
Selkirk Type B Gas Vents are to be installed and used in accordance with the
Canadian Fuel Gas Installation Code CSA-B149.1-00, the National Fuel Gas
Code NFPA 54, the Standard for Chimneys, Fireplace and Venting Systems
NFPA 211, the "International Fuel Gas Code" and/or applicable local/regional
codes.
CAUTION: WEAR GLOVES WHILE HANDLING METAL PARTS
TO AVOID PERSONAL INJURY. SHARP EDGES OR
PROJECTIONS CAN CUT YOU.
2. GENERAL
Before beginning installation be sure that the overall height and Gas Vent size
conform to building code requirements. Use Selkirk Gas Vent and Chimney
Sizing Handbook or the Fuel Gas Codes to select the correct Gas Vent
diameter. Avoid using a larger than necessary vent diameter.
Situate the Gas Vent in the structure so that it can be installed without cutting
joists, sill plates or major load bearing partitions or members. It is also important
to locate the base of the Gas Vent as near as possible to the heating appliance.
Selkirk Type B Gas Vent must be installed with 25mm (1") minimum air space
clearance to combustibles. Where the Gas Vent extends through inhabited
spaces, it must be enclosed with 25mm (1") clearance to avoid personal
contact and damage. These clearances are marked on all gas carrying items
and they apply whether they are horizontal or vertical, or pass through
floors, walls, roofs or framed spaces. The appropriate clearance should be
observed to joists, studs, subfloors, plywood, drywall, or plaster enclosures,
insulating sheathing, rafters, roofing, and any other materials classed as
combustible. Enclosure material should have a fire resistance rating at least
equal to that of adjacent floor or ceiling material. Keep electrical wires and
building insulation away and out of the required air space.
near the point where the Gas Vent is connected
A NOTICE SHOULD BE POSTED
to the appliance, with the following wording: "Connect this Gas Vent only to
gas burning appliances, as indicated in the installation instructions and do not
connect to incinerators, or liquid or solid fuel burning appliances". A reminder
also to homeowners to check the rain cap for icing during low ambient
temperatures.
3. GAS VENT JOINT METHOD
All joints in Selkirk Type B Gas Vent must be secured using the "Snap Lock"
feature. To use the Snap Lock feature, orient sections as shown in Fig.1 and
force adjacent piece together until a "SNAP" is heard, indicating full/proper
joint engagement. NOTE: Some local jurisdictions require a supplemental
screw(s) at joints to prevent disengagement of the joint. Although

INSTALLATION INSTRUCTIONS
Failure to follow the installation instructions could cause FIRE,
CARBON MONOXIDE POISONING, OR DEATH. If you are unsure of
installation requirements, call the Phone Number listed on the
instructions, 1-800-267-8178 or visit www.selkirkcanada.com.
not required under the terms of the UL
Listing because of the integral couplers,
screws are permitted to be installed at
the joints in 3" through 8" vent. In such
case, the screws should be located
aprox. 1/4" from overlapped edge and
must be maximum 1/4" in length so they
do not pierce or deform the inner liner.
A new Lock-Tab® feature provides the
equivalent of using a screw for this pur-
pose since, once engaged (with finger
or thumb until it bends into the groove in
the top/ outlet end of the adjacent piece),
it prevents the pipes from being
disengaged unless the tab is pried back out and dimples aligned.
Keep electrical wires and building
insulation away from gas vent and
out of the required air space

4. AIR SUPPLY
Gas appliances must have an adequate air supply for combustion, vent
operation, and ventilation. Special provisions for bringing in outside air may
be necessary in tight buildings or when appliances are in small rooms. Consult
