Clothes dryer – an appliance used to dry wet laundry by means of heat derived from the combustion of fuel gases. Dryer classifications are as follows:
Type 1 Household
1. Intended for use in residential homes
2. Gas supply pressure not exceeding 0.5 psi

6.13.1 - A dirt pocket shall be installed at the bottom of any piping or tubing on the final drop serving an appliance other than
(c) a clothes dryer; - The requirement for a manual shut-off valve specified in Clause 6.18.2 (b) to be readily accessible may be waived when it is located;
(b) behind a residential gas clothes dryer.

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);

7.5 Type 1 clothes dryers

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.

7.5.2 - A moisture-exhaust duct shall not terminate within 3 ft (1 m) in any direction of any pressure regulator vent termination or fresh-air intake.

7.5.5 - Type 1 clothes dryers shall be certified to ANSI Z21.5.1 / CSA 7.1 - Gas Clothes Dryers, Volume I, Type 1 Clothes Dryers.

7.5.3 - A moisture-exhaust duct shall not be secured with screws and shall not be connected into any vent connector, vent, or chimney.

7.5.4 - Except where permitted by Clause 4.13.2, a dryer shall have the following minimum clearances from combustible material:
(a) above — 6 in (150 mm);
(b) front — 24 in (600 mm); and
(c) back and sides — 6 in (150 mm).

8.3.7 - An air-supply opening shall not be located within 3 ft (1 m) of a moisture exhaust duct. In the case of Type 1 gas clothes dryer, this separation shall be not less than 3 ft (1 m) and in the case of Type 2 gas clothes dryer not less than 10 ft (3 m).
Note: A moisture-exhaust duct (e.g., a gas or electric clothes dryer discharge; spa exhaust) is considered to interfere with the combustion air intake when located within 3 ft (1 m) of the air intake.
