BACKGROUND

Reznor was founded in 1888 to manufacture the “Reznor” reflector heater, which used a luminous flame gas burner developed by George Reznor. This technological breakthrough was an immediate success and hastened the expansion of gas heating in residential and commercial applications. Technological development and innovation have been the hallmark of Reznor products through the years. The development of the forced air gas unit heater, the modular Thermocore heat exchanger, and the high-efficiency, V3® Series unit heaters have kept Reznor products at the forefront of technological advances in commercial and industrial gas heating. As a result of this pioneering role in the heating, makeup air, and ventilating equipment field, the products offered today are the most advanced in engineering design to satisfy a wide variety of applications.

PRODUCT SCOPE

Well-equipped engineering laboratories for both product development and testing can be found at many of the manufacturing sites. All domestic lab sites are agency approved.

Reznor Products include a complete line of heating, makeup air and ventilating systems, using gas, oil, hot water/steam, or

electric heat sources. Reznor heater catalogs are designed to aid the engineer, architect or contractor in specifying the correct equipment for all standard and special applications. Complete data is presented on unit heaters, duct furnaces, infrared heaters, makeup air systems, pre-engineered custom-designed systems, and evaporative cooling modules. Consult your local Reznor Sales Representative for further assistance in specifying Reznor Equipment for your specific application.

FACILITIES

Reznor heaters were first manufactured and sold in Mercer, Pennsylvania (70 miles north of Pittsburgh) in 1888. Over the years, the company has grown and expanded. Today, with sales worldwide, Reznor products are being manufactured at facilities throughout North America and Europe.

SERVICES

Product service requirements are handled through contractors and/or distributors, with backup from local representatives and factory-based service team. Replacement parts inventories for both warranty and non-warranty requirements are maintained at service centers throughout the country and at the manufacturing facilities.

DESCRIPTION

Reznor

Series Model UDAS gas-fired separated com-

ANSI Z83.8b

bustion unit heaters are available in 14 sizes ranging from 30,000 to 400,000 BTUH gas input. Sizes 30-125 are approved for residential application. All sizes are approved for commercial/industrial installations. Model UDAS heaters are designed for 82-83% thermal efficiency and are approved for installation in the United States and Canada by the Canadian Standards Association (CSA).

Reznor

Series unit heaters have a refreshing new appearance with a glossy white cabinet finish and less visible hardware. Each size cabinet is easily suspended from either 2 or 4 suspension points. Or, an optional hanger kit for Sizes 30-125 allows for ceiling mounting. The low voltage terminal strip on the outside of the cabinet makes connecting control wiring easy with no panels to remove. The addition of a “G” terminal to the low voltage strip, along with the new design of the circuit board, allows for fan only operation (without adding relays). All units have a factory installed gas line nipple to the exterior of the cabinet for easy gas service connection.

The preeminent new internal feature is the TCORE

2 ®

heat exchanger and single burner combustion system. Other standard features include a single-stage gas valve, multi-try direct spark ignition with 100% lockout, pressure switch to verify vent flow, resiliently isolated venter motor, venter wheel with improved housing, resiliently isolated axial fan and motor assembly, a high temperature limit control, interlock door switch, and a built-in disconnect switch. Sizes 30-125 also include a flame rollout safety switch. Operation is controlled through an integrated circuit board. The circuit board monitors heater operation and has LED diagnostic indicator lights to identify abnormalities in control functions.

The 1ST ever separated combustion system in the com- mercial/industrial heating industry was introduced on a Reznor heater in the 1960’s, and that proven technology is continued in this new separated combustion product. Model UDAS separated combustion units require installation of a specially designed combustion air/vent system including the unique concentric adapter box that allows for only one building penetration for both the vent and combustion air.

The new

Series unit heaters are designed to provide all the features you expect in a Reznor heater plus improved efficiency, easier installation, and a new look

and out.

DESCRIPTION

Reznor combustion unit heaters are available in 14 sizes ranging from 30,000 to 400,000 BTUH gas input. Model UDBS heaters are designed for 82-83% thermal efficiency and are approved for commercial/industrial installations in the United States and Canada by the Canadian Standards Association (CSA).

Reznor appearance with a glossy white cabinet finish and less visible hardware. Each size cabinet is easily suspended from four suspension points. The low voltage terminal strip on the outside of the cabinet makes connecting control wiring easy with no panels to remove. The addition of a “G” terminal to the low voltage strip, along with the new design of the circuit board, allows for blower only operation (without adding relays). All units have a factory installed gas line nipple to the exterior of the cabinet for easy gas service connection.

The preeminent new internal feature is the TCORE exchanger and single burner combustion system. Other standard features include a single-stage gas valve, multitry direct spark ignition with 100% lockout, pressure switch to verify vent flow, resiliently isolated venter motor, venter wheel with improved housing, a high temperature limit control, interlock door switch, and a built-in disconnect switch. Sizes 30-125 are equipped with a centrifugal blower and direct drive motor with multispeed taps. Sizes 30 and 45 are capable of handling up to .5” w.c. of external static pressure; Sizes 60-125 will handle up to .75” w.c. of external static pressure. Sizes 150-400 are equipped with a centrifugal blower with an adjustable belt drive and motor. All units are designed for use with optional 30° and 60° downturn nozzles with horizontal and vertical louvers. Operation is controlled through an integrated circuit board. The circuit board monitors heater operation and has LED diagnostic indicator lights to identify abnormalities in control functions.

The 1ST ever separated combustion system in the com- mercial/industrial heating industry was introduced on a Reznor heater in the 1960’s, and that proven technology is continued in this new separated combustion product. Model UDBS separated combustion units require installation of a specially designed combustion air/vent system including the unique concentric adapter box that allows for only one building penetration for both the vent and combustion air.

The new Series unit heaters are designed to provide all the features you expect in a Reznor heater plus improved efficiency, easier installation, and a new look

inside and out.

DESCRIPTION

Reznor® Series Model UDBP gas-fired unit heaters are available in 14 sizes ranging from 30,000 to 400,000 BTUH gas input. Model UDBP heaters are designed for 82-83% thermal efficiency and are approved for commercial/industrial installations in the United States and Canada by the Canadian Standards Association (CSA).

Reznor appearance with a glossy white cabinet finish and less visible hardware. Each size cabinet is easily suspended from four suspension points. The low voltage terminal strip on the outside of the cabinet makes connecting control wiring easy with no panels to remove. The addition of a “G” terminal to the strip, along with the new design of the circuit board, allows for blower only operation (without adding relays). All units have a factory installed gas line nipple to the exterior of the cabinet for easy gas service connection.

The preeminent new internal feature is the TCORE heat exchanger and single burner combustion system. Other standard features include a single-stage gas valve, multi-try direct spark ignition with 100% lockout, pressure switch to verify vent flow, resiliently isolated venter motor, venter wheel with improved housing, and a high temperature limit control. Sizes 30-125 are equipped with a centrifugal blower and direct drive motor with multispeed taps. Sizes 30 and 45 are capable of handling up to .5” w.c. of external static pressure; Sizes 60-125 will handle up to .75” w.c. of external static pressure. Sizes 150-400 are equipped with a centrifugal blower with an adjustable belt drive and motor. All units are designed for use with optional 30° and 60° downturn nozzles with horizontal and vertical louvers. Operation is controlled through an integrated circuit board. The circuit board monitors heater operation and has LED diagnostic indicator lights to identify abnormalities in control functions.

The new vide all the features you expect in a Reznor heater plus improved efficiency, easier installation, and a new look

both inside and out.

DESCRIPTION

The Model OH/OB Series oil-fired unit heaters are available in inputs of 118,000, 173,000, and 229,000 BTUH with 82% efficiency output. These completely packaged unit heaters burn No. 2 fuel oil.

Model OH heaters are equipped with a propeller fan. The fan is enclosed in an OSHA-type full safety fan guard.

Model OB heaters are equipped with a centrifugal blower. The blower has an adjustable belt drive and is capable of handling external pressure of .25" w.c. Blower models are equipped with a belt guard and a blower inlet guard.

All units feature a low-stress, 18-gauge steel exchanger and a heavy, 13-gauge combustion chamber with large, easily accessible, service panels. The oil burner assembly has a pressure-atomizing gun type burner that provides excellent flame retention and an integral fuel pump. The burner has an electric spark ignition system with an electronic cad-cell flame safety system with manual reset. All models have a flame observation port.

Standard features include fan and limit controls. The fan control prevents circulation of cold air at start-up and provides heat dissipation while the unit is hot after the burner shuts off. The safety limit control provides unit protection from high temperature caused by an airflow restriction or motor failure. All units are wired for 115 volt, 60 Hz power supply and can be controlled with a 24V thermostat.

Model OH/OB oil-fired unit heaters are approved for installation in The United States and Canada by the Canadian Standards Association (CSA).

NOTE: Not certified for residential use.

NOTES: Data based on 80oF enter- ing air and 60oF rise through the unit. Standard louvers set at maximum deflection are effective as indicated when ceiling height above heater is not over 4 ft. For higher mounting height or where spot heating is required, choose outlet and mounting height giving coverage to floor. Mounting close to the ceiling provides maximum heat utilization.

KEY:

A = Throw B = Spread (Side to side coverage with standard louvers) H = Mounting Height

NOTES: Data based on 80°F entering air temperature and 60°F rise through the unit. Standard horizontal louver set for maximum

down deflection. Table and drawing show approximate floor coverage at various mounting heights. NOTE that throw "A" and sideward spread "B" are increased as mounting height is reduced, due to floor bounce effect. Conversely the floor coverage reduces as mounting height increases. Horizontal louvers can be used to spread throw area "A" forward from the heater, and vertical louvers can be used to increase sideward spread "B". Vertical louvers set at maximum deflection will increase spread "B" approximately 10 feet, but will reduce maximum mounting height 4 feet. EXAMPLE: B200 at 20 ft. mounting height with standard louver setting gives a floor coverage of "A" = 24' x "B" = 26'. Using vertical louvers set at maximum sideward spread, the maximum mounting height would be 16 feet, and the floor coverage would be "A" = 26' and "B" = 28' plus 10' or 38'.

Blower Chart

Model B with Belt Drive Motor

Model B and BE unit heaters are designed to handle up to .5" w.c. of static pressure with temperature rises as shown from 45oF to 75oF. The following chart indicates the CFM, the motor HP, and the optional drive required to achieve the desired temperature rise with external pressures from 0 to .5" w.c.

Drive Option Key (see chart on next page):

AM __

N.R.

The "AM" drive will provide the selected CFM and temperature rise when installed with the total external static pressure listed but

MAY

require field-adjustment of the blower speed (CFM). Check the temperature rise and the motor amps. If adjustment is needed, follow "Blower Speed Adjustment" instructions in the heater installation manual.

The temperature rise and static pressure combination is not recommended for the heater size.

STD

The standard drive as set at the factory provides the selected CFM and temperature rise when installed with the external static pressure listed.

The standard drive will provide the selected CFM and temperature rise when installed with the total external static pressure listed but

REQUIRES

field-adjustment of the blower speed (CFM). Follow the "Blower Speed Adjustment" instructions in the heater installation manual.

NOTES: (1) Sizes 50-100 do not show a standard drive because they have a standard direct drive blower motor. For a

Size 50-100 with an optional belt-driven motor and blower, an "AM" option must be selected.

(2) If the unit includes an optional blower cabinet, see the chart below for pressure drop information.

Blower Curves

Model B with Direct Drive Motor

The blower curves for Models B (Sizes 25, 50, 75 and 100) with direct drive motors indicate the temperature rise available for each size of heater at a given total external static pressure. These units are designed and certified for total external static pressures up to .5" w.c. and temperature rises from 45°-75°F.

The direct drive motors are equipped with multispeed taps for speed adjustment as indicated on the curve charts. Models 25 and 75 are factory-wired to the medium speed tap; Models 50 and 100 are factory-wired to the high-speed tap.

NOTE: If the heater includes a blower cabinet, refer to appropriate pressure drop chart.

Installation Procedures

WARNING: Gas-fired appliances are not designed for use in hazardous atmospheres containing flammable vapors or combustible dust, or atmospheres containing chlorinated or halogenated hydrocarbons.

Installations in public garages or airplane hangars are permitted when in accordance with ANSI Z223.1 and NFPA 54 codes or CAN1-B149 and enforcing authorities.

FOR YOUR SAFETY

What to do if you smell gas:

• Do not try to light any appliance.

• Do not touch any electrical switch; do not use any phone in your building.

• Immediately call your gas supplier from a neighbor's phone. Follow the gas supplier's instructions.

• If you cannot reach your gas supplier, immediately call your fire department.

FOR YOUR SAFETY

Do not store or use gasoline or other flammable vapors and liquids in the

vicinity of this or any other appliance.

WARNING: Improper installation, adjustment, alteration, service, or maintenance can cause property damage, injury, or death. Read the installation, operation, and maintenance instructions thoroughly before installing or servicing this equipment.

Requirements for installation vary depending on the model of heater and the type of installation. Follow the manufacturer's

instructions and comply with all applicable codes.

Some venting requirements that apply to specific gas-fired models are shown on the following pages.

OPTIONAL POWER VENTING OF GRAVITY VENTED UNITS - Models F and B

Use only the Reznor® power venter designed for the particular model and size of heater.

Understand the operation before installing. When a venter is used with a heater, the room thermostat turns the venter on and off, and the venter turns the gas controls on and off. When the space calls for heat, the room thermostat contacts close the circuit which starts the venter. When the venter starts, air from the venter blower closes an air switch that is built into the venter.

Closing of the air flow switch sends an electric current to the burner controls, opening the gas valve and sending gas to the burners. When the thermostat is satisfied, the thermostat turns off the venter and the gas controls. As the venter blower stops, the airflow switch resets to the open position.

Venting/Inlet Air for Separated

Combustion Models - Applies to

Models UDAS, UDBS and SHE

Separated-combustion principles used in these Reznor

products.

● Air for combustion is mechanically induced from

outside the building, preventing dirt, lint, dust or other contaminants in the indoor atmosphere from entering the burner or combustion zone of the furnace.

● The airflow is metered to provide optimum and efficient

combustion that is unaffected by negative building pressure or wind.

● After combustion, the air is exhausted back to the

outdoor atmosphere.

Reznor these benefits while requiring only one building penetration. See the venting illustrations.

IMPORTANT NOTE: The following illustrations do not accurately picture all models, but the fundamental principle is the same. Refer to the heater installation manual for specific vent/inlet air requirements.

Optional Polytube Outlet Adapter - Apply to Model B

Description

The optional outlet nozzle is designed to allow the attachment of polytubetype air distribution for use in greenhouse and industrial buildings. Outlet on suspended heater may be either above, below, or directly in line with the heater discharge. A kit is available to floor mount the heater with outlet below the heater discharge (see illustration). Model B standard blower and drive are designed to handle rated CFM at .25 w.c. ESP, and will inflate a 24" tube up to 150 ft long. See table for proper free area, minimum number of holes and sizes. Units may be used for greenhouse heating and ventilating or in industrial applications requiring high mounting heights or spot heating by means of polytube distribution.

The total open or free area of the polytube is important. Polytube suppliers have a great deal of flexibility in placement and sizing of holes. Too small of a free area will cause overheating. Excessive open area may not permit the tube to inflate. See the table below for a guide in hole size and location. Spacing and hole size may be varied, but free area must not be less than shown for the heater being installed.

Greenhouse Application - For greenhouse use, the number of units required is generally based on an airflow volume of 1-1/2 to 2 CFM per square foot of house floor area. Depending on the heat loss requirements of the house type, location, and desired temperature above ambient, the ventilation requirements determine the number of distribution systems required and the heat loss determines the BTUH heater size required. As a general rule, a single system will serve a maximum house width of 30 ft and a length of 150 ft.
