Before locating the boiler, check:

Provide clearances:

 

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.

Failure to keep boiler area clear ￿ WARNING and free of combustible materials,

If you do not provide the recommended service NOTICE clearances shown, it may not be possible to service

the boiler without removing it from the space.

4. The Crest must be installed so that gas control system components are protected from dripping or spraying water or rain during operation or service.

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.

Incorrectly-sized expansion tank.

• 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 condensate drainage.
