GB300 BOILER INSTALLATION AND OPERATION INSTRUCTIONS

BOILER RATINGS & CAPACITIES

Before undertaking the installation of the GB300(S,W) boiler check the boiler rating plate to ensure that the boiler has been sized properly for the job. The rating label has been packed with the controls. The “Net I=B=R Ratings” specify the equivalent amount of direct cast iron radiation that the boiler can supply under normal conditions. Also ensure that the boiler has been set up for the type of gas available at the installation site. Other important considerations are the availability of an adequate electrical supply, fresh air for combustion and a suitable chimney or vent system.

BOILER LOCATION

1.Locate the boiler in an area that provides good access to the unit. Servicing may require the removal of jacket panels. Allow a minimum clearance of 2 ft, 0.61 m between adjacent construction and the boiler sides and draft hood. A minimum clearance of 4 ft, 1.22 m must be maintained between the front of the boiler and adjacent construction. Accessibility clearances should take precedence over fire protection clearances, or use which ever is greater.

2.An optimum site will be level, central to the piping system, close to a chimney and have adequate fresh air for combustion.

3.Ensure that the floor is structurally sound and will support the weight of the boiler. Never install a GB300(S,W) on a concrete floor that contains wires, cables, water pipes or hoses. This boiler is designed for non combustible floors only! Never install this boiler on combustible materials or carpeting even if a non- combustible foundation material is placed over them!

WARNING: Never install a GB300(S,W) boiler on top of combustible flooring! Failure to comply with this warning may result in a fire causing extensive property damage, severe personal injury or death!

4.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. A full concrete foundation is recommended to protect the boiler from moisture and debris, Figure 1.

NOTE: The boiler must be assembled on a level, non- combustible surface. If the floor is not level a pad must be poured to provide a level surface. If a concrete block base is used level it using non- combustible shims or grout.

5.DO NOT place this boiler in a location that would restrict the introduction of combustion air into the boiler.

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 an explosion or fire causing extensive property damage, severe personal injury or death!
