1.2 General
Installation
Information
Installation should be done by a qualied agency in accordance with the instructions
in this manual and in compliance with all codes and requirements of authorities having
jurisdiction. The instructions in this manual apply to Model SSCBL and Model RPBL.
WARRANTY: Warranty is void if......
a. Furnaces are used in atmospheres containing ammable vapors or
atmospheres containing chlorinated or halogenated hydrocarbons or any
contaminant (silicone, aluminium oxide, etc.) that adheres to the spark
ignition ame sensing probe.
b. Wiring is not in accordance with the diagram furnished with the heater.
c. Unit is installed without proper clearances to combustible materials.
d. Furnace air throughput is not adjusted within the range specied on the
rating plate.
1.4 Installation
Codes
1.3 Warranty Refer to the limited warranty form in the "Literature Bag".
The packaged systems in this manual include duct furnace(s) that are design-certied
to ANSI and CSA standards by the Canadian Standards Association. The duct fur-
naces are approved for installation in the United States and in Canada. All furnaces
are approved for use with either natural gas or propane. The type of gas for which the
furnace is equipped and the correct ring rate are shown on the rating plate attached
to the unit. Electrical characteristics are shown on the unit rating plate.
These units must be installed in accordance with local building codes. In the absence
of local codes, in the United States, the unit must be installed in accordance with the
National Fuel Gas Code NFPA/ANSI Z223.1 (latest edition). A Canadian installation
must be in accordance with the CSA B149.1 Natural Gas and Propane Installation
Code. These codes are available from CSA Information Services, 1-800-463-6727.
Local authorities having jurisdiction should be consulted before installation is made to
verify local codes and installation procedure requirements.
The separated-combustion furnaces in Model SSCBL are designed and manufactured
in accordance with the ANSI denition of separated combustion. That denition reads,
"Separated Combustion System Appliance: A system consisting of an appliance and a
vent cap(s) supplied by the manufacturer, and (1) combustion air connections between
the appliance and the outside atmosphere, and (2) ue gas connections between the
appliance and vent cap, of a type(s) specied by the manufacturer but supplied by the
installer, constructed so that, when installed in accordance with the manufacturer's
instructions, air for combustion is obtained from the outside atmosphere and ue gases
are discharged to the outside atmosphere." Separated combustion units are designed
to separate air for combustion and ue products from the environment of the building
in which the unit is installed. Separated combustion appliances are recommended for
use in dust laden and some corrosive fume environments.
Special Installations
(Aircraft Hangars/
Garages)
Installations in aircraft hangars should be in accordance with NFPA No. 409 (latest
edition), Standard for Aircraft Hangars; in public garages in accordance with NFPA
No. 88A (latest edition), Standard for Parking Structures; and for repair garages in
accordance with NFPA No. 88B (latest edition), Standard for Repair Garages. In Can-
ada, installations in aircraft hangars, repair garages, and parking garages should be in
accordance with the requirements of the enforcing authorities and in accordance with
CSA B149 codes.
All Installations These gas-red products are certied by ANSI Z83 family of standards governing
the safe usage of heating equipment in the industrial/commercial marketplace. This
includes using the heaters in makeup air applications to supply corridor pressurization
in commercial buildings such as ofce structures and apartment complexes.
The heaters are not certied as residential heating equipment and should not be used
as such.
2.0 Furnace
Location
Clearances from the heater and vent to combustible construction or material in stor-
age must conform with the National Fuel Gas Code ANSI Z223.1a (latest edition) per-
taining to gas-burning devices, and such material must not attain a temperature over
160°F by continued operation of the heater.

Form I-SSCBL/RPBL, P/N 149159 R8, Page 4
Location must comply with the clearances listed in Paragraph 4.2. There are a variety
of factors, such as system application, building structure, dimensions, and weight, that
contribute to selecting the location. Read the installation information in this manual and
select a location that complies with the requirements.
CAUTION: Do not locate an indoor Model SSCBL where it may be
exposed to water spray, rain, or dripping water.
Hazards of Chlorine The presence of chlorine vapors in the combustion air of gas-red heating equipment
presents a potential corrosion hazard. Chlorine will, when exposed to ame, precipitate
from the compound, usually freon or degreaser vapors, and go into solution with any
condensation that is present in the heat exchanger or associated parts. The result is
hydrochloric acid which readily attacks all metals including 300 grade stainless steel.
Care should be taken to separate these vapors from the combustion process. This
may be done by wise location of the furnace with regard to exhausters or prevailing
wind direction. Remember, chlorine is heavier than air. This fact should be kept in mind
when determining installation locations of heating equipment and building exhaust sys-
tems.
3.0 Uncrating and
Preparation
3.1 Uncrating and Inspecting
This furnace was test operated and inspected at the factory prior to crating and was
in operating condition. If the equipment has incurred any damage in shipment, docu-
ment the damage with the transporting agency and immediately contact an authorized
Reznor® distributor. If you are an authorized Distributor, follow the FOB freight policy
procedures as published by Reznor for Reznor® products.
Check the rating plate for the gas specications of the furnace and electrical character-
istics of the unit to be sure that they are compatible with the gas and electric supplies
at the installation site.
Shipped-Separate Components
Read this booklet and become familiar with the installation requirements of your par-
ticular furnace. If you do not have knowledge of local requirements, check with the local
gas company or any other local agencies who might have requirements concerning
this installation. Before beginning, make preparations for necessary supplies, tools,
and manpower.

Vent/Combustion Air
Terminal Kit - Required
on ALL SSCBL
Installations
All Model SSCBL installations require a vent/combustion air kit (Option CC2 or CC6)
including a concentric adapter box for each duct furnace. See page 19 (Option CC6)
or page 22 (Option CC2) for the component list of each kit. Be sure all of the factory-
supplied and eld-supplied parts needed for the vent/combustion air kit(s) are at the
job site.
Other shipped-separate options could include a roof curb, an outside air hood, a gas
shutoff valve, a thermostat, an optional control switch, a remote console, a vent exten-
sion, a gas supply regulator, and/or a disconnect switch. If ordered with either an
evaporative cooling module or a DX or chilled water cooling coil module, the module
is shipped separately. A drain and ll or freeze kit and a water hammer arrestor are
shipped-separate options for an evaporative cooling module.
