WARNING: At elevations greater than 2000 ft, 660 m, the combustion of the GT must be checked with a calibrated combustion analyzer to ensure safe and reliable operation. Consult the Operating Instructions Section for instructions on adjusting the input to provide proper operation. Failure to comply with this warning can result in excessive levels of carbon monoxide causing severe personal injury or death!

BOILER LOCATION

WARNING: The clearances to combustible construction listed inTable 1 must be maintained. Failure to comply with this warning can result in a extensive property damage, severe personal injury or death!

CAUTION: This boiler is designed to operate only in residential and commercial heating systems. It is not intended for:

1.Outdoor installations, or unheated spaces, which can cause freezing.

2.Process heating of potable water, or any other fluids.

3.Un-pressurized, and gravity feed heating systems.

4.Heating systems with very low pressures or flow.

Improper use or installation will seriously damage the boiler, voiding warranty!

1.Locate the boiler in an area that provides good access to the unit. Keep in mind that servicing may require the removal of jacket panels. Accessibility clearances should take precedence over fire protection clearances. Table 1 lists the minimum clearances for servicing, however 24 in, 610 mm is recommended.

2.An optimum site will be level, central to the hot water piping system and close to an outside wall.

NOTE: This boiler is designed for direct placement on a combustible floor. Never install this boiler on carpeting!

3.DO NOT install this boiler in a location that would subject any of the gas ignition components to direct contact with water or excessive moisture during operation or servicing. The boiler location ambient temperature must be no less than 50°F, 10°C including the condensate line.

4.NEVER store objects on or around the boiler.

5.This boiler may be wall mounted. See the Wall Hung Conversion section listed in the table of contents.

WARNING: Never store combustible materials, gasoline or any product containing flammable vapors or liquids in the vicinity of the boiler. Failure to comply with this warning can result in extensive property damage, severe personal injury or death!

WARNING: Liquefied Petroleum, LP, gas is heavier than air; it is imperative that your boiler is not installed in a pit or similar location that will permit heavier than air gas to collect. Local Codes may require appliances fueled with LP gas be provided with an approved means, of removing unburned gases from the room. Check your local codes for this requirement. Failure to comply with this warning can result in extensive property damage, severe personal injury or death!
