2.0 Furnace
Location
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 4.1. 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 the heater where it may be exposed to
water spray, rain or dripping water.
1.0 General
(cont'd)
1.4 Installation
Codes (cont'd)
The heaters are not certified as residential heating equipment and should not be used
as such.
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.
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 war-
ranty is void, and the manufacturer disclaims any responsibility for the
duct furnace and/or the application.
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 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 furnace has incurred any damage in shipment, document 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 specifications and electrical characteristics of the
furnace to be sure that they are compatible with the gas and electric supplies at the
installation site.
The bottom corners are fastened to the crate with angle clips. Remove the lag screws
from the shipping clips. Remove the clips and return the bolts to the heater legs to
support the corner leg and the heater bottom. Putting the bolts back in the heater
is required.
3.2 Preparing for
Installation
3.2.1 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 concern-
ing this installation. Before beginning, make preparations for necessary supplies, tools,
and manpower.
Vent/Combustion Air
Terminal Kit - Required
on ALL Installations
A vent/combustion air kit (Option CC2 or CC6) including a concentric adapter box is
required for all installations. See page 14 (Option CC6) or page 17 (Option CC2) for a
component list. Be sure all of the factory-supplied and field-supplied parts needed are
at the job site.
