This appliance requires a special venting system. Use only the vent materials specified in this manual. Failure to follow all instructions can result in flue gas spillage and carbon monoxide emissions, causing severe personal injury or death.
1.Check for nearby connection to:
•System water piping
•Venting connections
•Gas supply piping
•Electrical power
2.Locate the appliance so that if water connections should leak, water damage will not occur. When such locations cannot be avoided, it is recommended that a suitable drain pan, adequately drained, be installed under the appliance. The pan must not restrict combustion air flow. Under no circumstances is the manufacturer to be held responsible for water damage in connection with this appliance, or any of its components.
3.Check area around the boiler. Remove any combustible materials, gasoline and other flammable liquids.

5. If a new boiler will replace an existing boiler, check for and correct system problems, such as:
• System leaks causing oxygen corrosion or heat exchanger cracks from hard water deposits.
•
• Lack of freeze protection in boiler water causing system and boiler to freeze and leak.
6. The appliance must be installed on a level floor, both front to back and side to side, for proper
