INSTALLATION PROCEDURE

LOCATION OF UNIT

1.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 unit. The pan must not restrict combustion airflow. Under no circumstances is the manufacturer to be held responsible for water damage in connection with this unit, or any of its components.

2.The appliance must be installed so that the ignition system components are protected from water (dripping, spraying, etc.) during appliance operation and service (circulator replacement, control replacement, etc.).

3.Appliances located in a residential garage and in adjacent spaces that open to the garage and are not part of the living space of a dwelling unit must be installed so that all burners and burner ignition devices have a minimum clearance of not less than 18" (46cm) above the floor. The appliance must be located or protected so that it is not subject to physical damage by a moving vehicle.

4.DO NOT install this appliance in any location where gasoline or flammable vapors are likely to be present.

5.The appliance must be installed on a level floor. Combustible floor locations may be used. Maintain required clearances from combustible surfaces.

6.	The	appliance	must	not be	installed	on carpet.
7.	The	appliance must be installed indoors where it
	is	protected	from	exposure	to wind,	rain and

weather.

8.This appliance may condense the products of combustion when operating at water temperatures below 130°F (54.4°C). Ensure that the appliance is located near an acceptable drain where the condensate from the heat exchanger and venting system may be properly collected, neutralized and disposed.
