1.2 General

Description

The information in this manual applies to Reznor

Model RDF Series 3 direct-red

makeup air heating systems. The typical system consists of a direct-red, natural gas-

fueled burner, and a draw-through blower housed in a weatherized cabinet. The sys-

tem may be installed either indoors or outdoors.

This direct-red makeup air system provides tempered makeup air. Makeup air is

dened as air that enters a building or area due to negative pressure created by an air

exhaust load in excess of the volume of entering air. This system warms the outside

air and monitors the volume and temperature of the makeup air added to the building.

The system may be used to provide ventilation in whole building or in spot applications.

In whole building applications, adding controlled makeup air will cause less inltration

of dust and dirt; will eliminate continuous backdraft in chimneys and vents; and will

reduce space heating fuel costs.

This system is available with various air control options to meet a wide range of appli-

cation requirements. Depending on the air control option ordered, the supply air vol-

ume may be varied or the outside air may be supplemented with up to 75% building air

(recirculation) for increased energy savings.

These systems are designed-certied to ANSI and CSA Standards. (NOTE: Optional

recirculation is available for U.S. installations only; recirculation is not available for

Canadian installations.)

In order to retain certication, the installer must adhere to the installation and operation

requirements in the instruction manual. These direct-red makeup air systems are not

approved for residential use.

1.3 Warranty

Refer to the limited warranty information on the warranty card included in the "Owner's

Envelope".

1.4 Installation

Codes/

Requirements

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 qualied agency installing this system is responsible for the installa-

tion.

These units must be installed in accordance with local building codes. In the absence

of local codes, the unit must be installed in accordance with the National Fuel Gas

Code ANSI Z223.1a (latest edition) or CAN/CGA B149, Installation Codes for Gas

Burning Appliances. These codes are available from CSA Information Services, 1-800-

463-6727.

Before installation, always consult authorities having local jurisdiction to verify that

local codes and procedures are being followed.

The building should always provide adequate relief for the heater to operate at its

rated capacity. It should be noted that this can be accomplished by taking into account,

through standard engineering methods, the structure's designed inltration rate; by

providing properly sized relief openings; by interlocking a powered exhaust system; or

by a combination of these methods. Excessive recirculation or insufcient ventila-

tion air which results in inadequate dilution of the combustion products gener-

ated by the heater may create hazardous concentrations of carbon dioxide, car-

bon monoxide, nitrogen dioxide, and other combustion products into the heated

space.

If the failure or malfunction of this heater creates a hazard to other fuel burning equip-

ment in the building, interlock the system to open inlet dampers or other such devices.

Recirculation Requirements - Do not install a system with optional recirculation

(building air) in the presence of ammable solids, liquids, or gases; explosive materials

(i.e., grain dust, coal dust, gun powder, etc.); or substances which may become toxic

when exposed to heat (i.e. refrigerants, aerosols, etc.). If a system with recirculation is

being installed in an area where propane fork trucks or other fossil fuel powered equip-

ment are used, the ventilation requirements for that equipment must be met. Recir-

culation is not recommended in uninsulated buildings where outside temperatures fall

below 32°F (0°C).

If in doubt regarding an application, consult the heater manufacturer's representative

before installation.
