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 duct furnace Model RP and Model
HRPD.
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.
e. Duct furnace is installed in a process or drying application without factory
authorization. (Any use in a process or drying application voids agency
certification.)
1.4 Installation
Codes
1.3 Warranty Refer to the limited warranty form in the "Literature Bag".
The outdoor duct furnace models in this manual are design-certified to ANSI and CSA
standards by the Canadian Standards Association. All models are approved for instal-
lation 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 firing rate are shown on the rating plate attached to the unit. Electrical charac-
teristics 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.
WARNING
These duct furnaces are not certified or approved for use in
drying or process applications. If a duct furnace is to be used in a
drying or process application, contact the factory for application
guidelines and manufacturer's authorization. Without factory
authorization, the warranty is void, and the manufacturer disclaims
any responsibility for the duct furnace and/or the application.
2.0 Furnace
Location
2.1 General Recommendations
A duct furnace is designed for connection to an inlet and an outlet duct and depends
on an external air handler. Location must comply with the clearances listed in Para-
graph 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.
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, precipi-
tate from the compound, usually freon or degreaser vapors, and go into solution with
