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!
