*Venting Requirements: This unit requires venting pipe with an inner diameter of 4 Inches. Please see the Venting Components section on this page if available for venting pipe that must be used with this unit.
Homeowners who have a Napoleon GDS26 Castlemore Direct Vent Cast Iron gas stove and who need to complete their venting installation through a combustible wall need this GD177 Through-Wall Vent Kit.
The kit includes a terminal, a mounting plate, and a black trim collar. After making the through-wall transition, the mounting looks professional and finished, leaving you to worry about other parts of your home instead of your venting installation.
