in this manual and in compliance with all codes and requirements of authorities having
jurisdiction. The instructions in this manual apply to packaged duct furnace and blower
Model Series RPB.
WARRANTY: Warranty is void if......
a. Furnaces are used in atmospheres containing flammable vapors or
atmospheres containing chlorinated or halogenated hydrocarbons or any
contaminant (silicone, aluminium oxide, etc.) that adheres to the spark
ignition flame 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 or
without proper ventilation and air for combustion. (Paragraphs 2.2 & 4.2.)
d. Furnace air throughput is not adjusted within the range specified on the
rating plate.
1.4 Installation
Codes
1.3 Warranty Refer to the limited warranty form in the "Literature Bag".
The outdoor packaged systems in this manual are design-certified to ANSI and CSA
standards by the Canadian Standards Association. These models are approved for
installation in the United States and in Canada. The furnaces are approved for use
with either natural gas or propane. The type of gas for which the furnace is equipped
and the correct firing 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.
2.0 Furnace
Location
2.1 General Recommendations
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. If equipped with an outside air hood, it is recom-
mended that the inlet to the hood not be facing into the prevailing wind.
Read the installation information in this manual and select a location that complies with
the requirements.
2.2 Combustion Air
Requirements
The combustion air and flue gas openings are carefully designed screened openings
located on the side of each unit just above the control access panel. Location of the
flue opening directly above the air intakes discourages recirculation of combustion
products.
Hazards of Chlorine - The presence of chlorine vapors in the combustion air of gas-
fired heating equipment presents a potential corrosion hazard. Chlorine will, when
exposed to flame, 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 includ-
ing 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 furnace has incurred any damage in shipment, document the
damage with the transporting agency and immediately contact an authorized Reznor ®
