1.2 General

Installation

Information

Installation should be done by a qualified 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 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
