Abstract
A throttled vent termination or cap for use in conjunction with a direct vent appliance and venting system is provided. The direct vent termination includes an inner pipe and a concentric outer housing surrounding the inner pipe to form a void between the inner pipe and the outer housing. The void adapted to provide intake air to the air intake section of the vent system. An end cap is provided at a first end of the outer pipe, the inner pipe to the end cap and having an exhaust opening therein. An intake region is formed in the outer housing providing access to the void. A throttle cover which is configured to be movably positioned and thereafter secured at one of a number of positions over the intake region using a throttle guide is provided to thereby regulate air flow into the void.
