2.Installation Codes

Both this installation manual and the appropriate venting manual are shipped with the heater. Verify that the literature is correct for the heater being installed. If either manual is missing or incorrect, contact your distributor before beginning installation.

The instructions in this manual apply only to the models listed.

Installation should be done by a qualified agency in accordance with these in- structions. The qualified service agency installing this heater is responsible for the installation.

These units must be installed in accordance with local building codes. In the ab- sence of local codes, in the United States, the unit must be installed in accordance with the National Fuel Gas Code, ANSI Z223.1. A Canadian installation must be in accordance with the CAN/CGA B149 Installation Codes. These codes are avail- able from CSA Information Services, 1-800-463-6727. Local authorities having jurisdiction should be consulted before installation is made to verify local codes and installation procedure requirements.
