ANSI Z21.97-2012/CSA 2.41-2012 - Outdoor decorative gas appliances
Preface
This publication represents a basic standard for safe operation, substantial and durable construction, and acceptable performance of outdoor decorative gas appliances. It is the result of years of experience in the manufacture, testing, installation, maintenance, inspection and research on appliances designed for the utilization of gas. There are risks of injury to persons inherent in appliances that, if completely eliminated, would defeat the utility of the appliance. The provisions in this Standard are intended to help reduce such risks while retaining the normal function of the appliance.Scope
1.1 This standard applies to newly produced, decorative gas appliances for outdoor installation (see Section 3 - Definitions), constructed entirely of new, unused parts and materials; hereinafter referred to as appliance. Appliances submitted for examination under this standard shall be classified as one of the following: portable, stationary or built-in. 1.2 Appliances may be for:- Connection to a fixed fuel piping system; or
- Connection to a self-contained liquefied petroleum (LP) gas supply system (see Section 3 - Definitions). Cylinder(s) for a self-contained system may be either remote to the appliance, or integrally mounted on the appliance, and shall be designed for vapor withdrawal only.
- Appliances with input ratings less than 60,000 Btu/hr (17 584 W) shall be designed to accommodate a vertically mounted integral cylinder with a maximum size of 20 lb (9.1kg) of fuel.
- Appliances with input ratings greater than or equal to 60,000 Btu/hr (17 584 W) may be designed to accommodate a vertically mounted integral cylinder with a maximum size of 30 lb (13.6 kg) of fuel.
- Appliances with input ratings greater than or equal to 80,000 Btu/hr (23 446 W) may be designed for not more than two vertically mounted integral vapor withdrawal cylinders, each with a maximum size of 20 lb (9.1 kg) of fuel.
- Portable appliances intended for table top use shall have input ratings limited to not more than 15,000 Btu/hr (4 396 W) and shall be designed to accommodate a vertically mounted cylinder with a maximum size of 16.4 oz (465 g) of fuel.
- Portable appliances with input ratings not greater than or equal to 25,000 Btu/hr (7 327 W) may be designed for the use of not more than two cylinders, each with a maximum size of 16.4 oz (465 g) of fuel.
- Appliances designed for use with remote LP-cylinders shall be limited to one cylinder of maximum 30 lb (13.6 kg) of fuel or two cylinders with maximum of 20 lb (9.1kg) of fuel each.
