SIDE WALL VENTING INSTALLATION
(see illustration #2 below)
1. The pipe may be mortared in directly without using a wall thimble, if the wall is non-combustible. Penetrating a combustible
wall requires the use of a wall thimble. Install wall thimble into wall, observing the aforementioned rules and/or local building
codes. Select the point of wall penetration where the minimum 1/4 “ per foot of slope (6.4 mm per 305 mm) can be maintained. A
framed opening is required to insert the thimble halves. The thimble is adjustable for different wall thicknesses. The termination
cap is to be installed no less than 5-1/2 in. from the combustible exterior sidewall. Caulk around outside edge of plates as
necessary and fasten to wall using suitable screws or nails. The vent pipe must be sealed at wall thimble as per code regarding
continuous vapor barrier.
2. The system can now be assembled through the thimble (attach the termination first - note “UP” arrow) and then back to the
appliance as per illustration using JOINT PROCEDURE as described on page #3. A gear clamp must be installed around the pipe
on the inside of wall to trap pipe in position so that the system cannot be moved in or out of wall. This applies to both combustible
and non-combustible walls
3. The system must be supported along its horizontal length at all elbow locations and every forty-eight inches or less using straps
around pipes maintaining clearance to combustibles as per table on page 3.
4. The horizontal distance of the system from the appliance flue collar to the outside of the Horizontal termination cannot be
greater than that specified in the manufacturer’s installation instructions and not be less than four (4) feet unless the vent is
through a non-combustible wall.
NOTE:
Any horizontally installed portion of a venting system shall have a slope (upwards for Category II, III, or IV
appliances or downwards for Category III or IV appliances) not less than 1/4” (6.4 mm) every 12 inches (305
mm) to prevent collection of condensate at any location in the assembly. Fasteners must not penetrate the
components of the system either when joining pipes and fittings or using support straps.
