The Selkirk Chimney System (SCS) is ideal for venting residential heating appliances burning wood, #2 oil, and natural and LP gas. They have been
specifically designed for today’s modern, high-efficiency “airtight” wood stoves. They are designed for gravity (natural draft), nonpositive internal pressure
venting only. The SCS is usable on any appliance having a power burner (such as an oil furnace) if that appliance operates with neutral or negative draft
at its outlet. Non-residential appliances which may cause positive pressure in the chimney should use a Selkirk Commercial Model PS or IPS system.
NOTE: See separate catalog for Canadian installation.
See separate catalog for 16" - 24" UTL / GTL
IMPORTANT
This catalog references ULTRA-TEMP/GALVA-TEMP Chimney Systems with maximum test temperatures under Underwriters’ Laboratories Safety
Standard for Factory-Built Chimneys (UL®-103).
FRAMING / SUPPORTS:
All Selkirk Supports are designed to carry four times the combined weight of each system at maximum allowable height.
* All framing dimensions may be up to 1/2” more, but not less than the above values.
Check support dimensions before using.
** 4" chimney approved for use at clearance provided by Ceiling Support
NOTE: (A) 20 feet of chimney may be suspended below a roof support with all
joints securely threaded, using locking bands or screws.
Sloped ceilings and roofs will not have a square opening, but need to maintain 2".
The table only works on flat roof +/or ceiling penetrations.
4" components support 50 feet: Ceiling Supports (BCS, LCS and CSG), Wall
Support (WS), Roof Support (RS) and Anchor Plate (AP).
