Clause 7.5.1 - A dryer shall be equipped with a moisture-exhaust duct that terminates outside the building, and the duct shall be constructed of a material that is
(a) noncombustible; or
(b) certified as meeting the requirements for Class 1 air ducts contained in CAN/ULC-S110.

Clause 6.21.3 - Except as specified in Clause 7.22.3, a corrugated metal gas connector certified to ANSI Z21.24/CSA 6.10 may be used to connect
(a) a range, refrigerator, clothes dryer, or built-in counter appliance to piping or tubing, provided that the connector length does not exceed 6 ft (2 m);

I just use regular old aluminum c vent and taped joints with no screws and minimal elbows for optimal flow. I don't use a low profile hood for outside, I use one that allows a full 4" opening and no rodent screens.
I pipe right down to behind the dryer with whatever gas product is most feasible for that particular residence, and then use a 6" connector to make the final connection to the dryer for servicing. I also have the gas valve upstream.
