Page 3
Direct all questions to your RBI distributor or contact the
RBI Customer Service Department, 260 North Elm Street,
Westfi eld, MA 01085 for U.S. or 7555 Tranmere Drive,
Mississauga ONT L5S 1L4 for Canada. Always include the
model and serial numbers from the rating plate of the
boiler/water heater in question.
RATINGS & CAPACITIES
Before undertaking the installation of the Series 8800
and 8900 boiler/water heater check the rating plate to
ensure that the unit has been sized properly for the job.
The “Net I=B=R Ratings” specify the equivalent amount
of direct copper radiation that the unit can supply under
normal conditions. Also ensure that the unit 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/WATER HEATER LOCATION
1. Locate the boiler/water heater in an area that
provides good access to the unit. Servicing may
require the removal of jacket panels. Allow the
minimum clearances between adjacent construction
and the boiler/water heater as listed in Table 1 or 1A.
NOTE: Service clearances are not mandatory, but
are recommended to ensure ease of service should
it be required.

2. An optimum site will be level, central to the piping
system, close to a chimney and have adequate fresh
air for combustion. Ensure that the boiler/water heater
is level from front to back and from side to side. Use
metal shims to level the boiler/water heater. Electrical
and electronic components must also be protected
from exposure to water during operation and
maintenance. DO NOT install this boiler/water heater
in a location that would subject any of the gas ignition
components to direct contact with water or excessive
moisture during operation or servicing.
3. Ensure that the fl oor is structurally sound and will
support the weight of the boiler/water heater.
NOTE: Never install a Series 8800 or 8900 boiler/
water heater on a concrete fl oor that contains wires,
cables, water pipes or hoses. This boiler/water
heater is designed for noncombustible fl oors only!
Never install this boiler/water heater on combustible
materials or carpeting even if a non-combustible
foundation material is placed over them!
4. Locate the boiler/water heater in an area that will
prevent water damage to adjacent construction
should a leak occur or during routine maintenance.
If such a location doesn’t exist, a suitable drain pan
that’s adequately drained must be installed under
the unit. The pan must not restrict the flow of
combustion air to the unit.
5. DO NOT place this boiler/water heater in a location
that would restrict the introduction of combustion air
into the unit or subject it to a negative pressure, see
“GENERAL VENTING GUIDELINES”.
6. NEVER place this boiler/water heater in a location
that would subject it to temperatures at or near
freezing.
WARNING: Never store combustible materials,
gasoline or any product containing fl ammable vapors
or liquids in the vicinity of the boiler/water heater.
Failure to comply with this warning can result in an
explosion or fi re causing extensive property damage,
severe personal injury or death!
