Installation Guide

1. The vent system must terminate at least 3 feet above the roof line and at least 2 feet higher than

any portion of the building within 10 feet.

2. When terminated at a height of more than 6 feet the stack must be supported by a

Saf-T Vent CI Plus Guy Section.

3. The vent system must terminate with one of the Saf-T Vent Terminations;

except:

(a) Category I or II appliances (natural draft) must use a Saf-T Vent Rain Cap.

(b) Vent systems without provisions for draining rain water must use a Saf-T Vent Rain Cap.

manufacturer are permitted.

4. The total continuous distance of the vent system from the appliance flue collar to the termination

shall not exceed that specified in the appliance manufacturer’s installation instructions. When venting

natural draft appliances the termination must be at least 5 feet above the topmost draft hood. Otherwise

a Listed mechanical draft inducing device is required.

5. In general, systems installed in cold climates perform best, and condensation is reduced, when

the system is fully enclosed by some part of the building structure. When installing into a combustible

square or rectangular vertical chase, the Coupler Band bracket must be positioned into a corner of

the chase to provide the clearance as UL listed.

6. In cold climates do not install a condensate drain on the exterior of the building. Doing so may

result in dangerous icy conditions on surfaces near the drain and may cause damage to the vent

system and/or the building exterior. Selkirk Corporation will NOT be held liable for any personal

injury or property damage due to any formation of ice.

7. Vertical supports are required after every transition to vertical and as specified in the table below.

Vertical supports are also required after every offset elbow.
