GMS8, GHS8, GAS-FIRED GDS8 AIR WARM SINGLE STAGE INSTALLATION Installer. Affix FURNACE INSTRUCTIONS all manuals adjacent (CATEGORY to the unit. 1) These furnaces comply with requirements embodied in the American National Standard / National Standard of Canada ANSI Z21.47.CSA-2.3 Gas Fired Central Furnaces. _lb RECOGNIZE THIS SYMBOL ATTENTION AS A SAFETY PRECAUTION. INSTALLING PERSONNEL As a professional installer, you have an obligation to know the product better than the customer. This includes all safety precautions and related items. Prior to actual installation, thoroughly familiarize yourself with this Instruction Manual. Pay special attention to all safety warnings. Often during installation or repair, it is possible to place yourself in a position which is more hazardous than when the unit is in operation. Remember, it is your responsibility to install the product safely and to know it well enough to be able to instruct a customer in its safe use. Safety is a matter of common sense...a matter of thinking before acting. Most dealers have a list of specific, good safety practices...follow them. The precautions listed in this Installation Manual are intended as supplemental to existing practices. However, if there is a direct conflict between existing practices and the content of this manual, the precautions listed here take precedence. *NOTE: or our website Please referred IO-294A contact for the applicable to in this your distributor product data book manual.
