2.2 Venting

2.2.1 Vent Categories

Depending upon desired Brute Deluxe venting, it may be considered a Category I or a Category III appliance. In general, a vertical vent system will be a Category I system. However, in rare instances, a vertical vent system may be considered Category III. In the U.S., the National Fuel Gas Code (ANSI Z223.1-Latest Edition), or in Canada the CSA B149.1 (latest edition), defines a Category I vent system, and includes rules and tables to size these vent systems. If the Brute Deluxe’s vertical vent system does not satisfy the criteria for Category I venting, it must be vented as a Category III system.

All Brute Deluxe vent systems which discharge horizontally (without the use of a power venter) are considered Category III vent systems.

2.2.2 Category I Vent

When vented as a category I appliance, the vent system must conform to the National Fuel Gas Code (ANSI Z223.1-Latest Edition) in the U.S., or in Canada, to CSA B149.1 (latest edition). The vent system must be sized and installed for a Category I Fan-Assisted Appliance.

If chimney height is greater than 25 feet, or if multiple units are vented into the same vertical vent, a barometric damper must be installed on each appliance, such that the flue draft does not exceed (negative) 0.1" w.c.

If using a power venter for any type of Category I venting, the draft should be set between (negative) 0.01 and 0.10" w.c.

2.2.3 Common Venting Systems

Brute Deluxe units are Category I fan-assisted when vented vertically and adhering to all applicable codes.

When common venting Brute Deluxe fan-assisted unit with other appliances through one shared vertical duct called a “common vent”, special care must be taken by the installer to ensure safe operation. In the event that the common vent is blocked, it is possible, especially for fan-assisted devices, to vent backwards through non- operating appliances sharing the vent, allowing combustion products to infiltrate occupied spaces. If the

appliances are allowed to operate in this condition, serious injury or death may occur.

may lead to serious injury or death. If safe operation of all appliances connected to a common vent cannot be assured, including prevention of spillage of flue gasses into living spaces, common venting should not be applied, and appliances should each be vented separately.

Proper vent sizing, construction and safety requirements from the National Fuel Gas Code, ANSI Z223.1 or in Canada, from CSA B149.1 as well as all applicable local codes must be followed.

As an additional precaution, it is recommended that a Carbon Monoxide (CO) alarm be installed in all enclosed spaces containing combustion appliances.

Brute Deluxe units are not allowed to be vented into a common horizontal vent system, unless a properly sized vent fan is used, and the common vent system is properly designed by the vent fan manufacturer or a qualified engineer.

Refer to the installation and operating instructions on all appliances to be common vented for instructions, warnings, restrictions and safety requirements. If safe operation of all appliances connected to a common vent cannot be assured, including prevention of spillage of flue gasses into living spaces, common venting should not be applied, and appliances should each be vented separately.

2.2.4 Category III Vent

When the Brute Deluxe is vented with horizontal discharge, it must be installed per this installation manual and the venting system manufacturer’s installation instructions. The vent system must be sealed stainless steel (see Table 5).

Route the vent pipe to the heater as directly as possible. Seal all joints and provide adequate hangers as required in the venting system manufacturer’s Instal-
