INSTALLATION
Code Requirements
Installation must be in accordance with local codes, or in the absence of local codes, with the latest editions of the National Fuel Gas Code, ANSI Z223.1, and the National Electrical Code, ANSI/NFPA 70. In Canada, installations must conform with the current CSA B149 and the Canadian Electrical Code Part 1 CSA C22.2 No.1. Where required by the authority having jurisdic- tion, the installation must conform to American Society of Mechanical Engineers Safety Code for Controls and Safety Devices for Automatically Fired Boilers,
Mounting Base
Boiler should be mounted on a level surface. Each boiler is designed with a
In addition, the boiler shall be installed such that the gas ignition system components are protected from water (dripping, spraying, rain, etc.) during appliance operation and service (circulator replacement, control replacement, etc.)
