Provide oil-red unit heaters manufactured as Reznor
®
brand units. The units shall be completely packaged
and arranged for ceiling suspension with four-point threaded suspension sockets. They shall be equipped for
use with #2 oil using a pressure-atomizing gun-type power burner, a single-stage fuel pump, and an electric
spark ignition with an automatic cad-cell ame safety system with manual reset.
Heaters are to be equipped with a heavy, 13 gauge combustion chamber and low stress 18 gauge steel heat
exchanger. All sizes shall include ame observation port, CO
2
sample port, and service and cleanout access
panels.
Each unit is to be equipped with a combination fan and limit switch with manual fan switch for safety and com-
fort control. The units are to be used with 115 volt supply and have a 24-volt control transformer.
Model OH heaters are provided with a propeller fan and a totally enclosed fan motor with internal overloads.
Each unit is to be equipped with a burner service tray, an OSHA-type fan guard, and horizontal (vertical) air
directional louvers.
Model OH unit heaters are design certied by Underwriters Laboratories (UL) or certied by the Canadian
Standards Association (CSA).

Provide gravity-vented, high-efciency, gas-red unit heaters manufactured as Reznor
®
brand units. Units are
designed to take combustion air from the indoor space and vent to the outdoors.
Model B - Gas-red, blower, gravity-vented model
Each Model B series unit shall be equipped for use with (natural) (propane) gas and (120/1) (230/1) (460/3)
(575/3) volt power supply.
The heat exchanger shall be aluminized (E-3 stainless) (409 stainless) steel. Die-formed burners shall be of
aluminized steel and include ared ports and a stainless steel insert. The units shall be designed to provide
80% thermal efciency.
Controls include a 24-volt control transformer; single-stage (two-stage) gas control system; an intermittent
spark pilot with electronic ame supervision (intermittent spark pilot with electronic ame supervision and timed
lockout); fan and limit safety controls; a centrifugal blower with (direct) (adjustable belt) drive; and an (open,
drip-proof) (totally enclosed) blower motor with internal overloads.
Each unit must be able to overcome .25" w.c. (.5" w.c.) of external static pressure (and may be equipped with
an OSHA-type belt and/or blower inlet guard).
The cabinet is equipped with horizontal (vertical) louvers (downturn nozzles) for directing airow or with a duct
ange. The unit is arranged for ceiling suspension with 4-point threaded hanger connections (hanger kits).
Model B unit heaters are design certied to ANSI and CAN/CGA Standards by the Canadian Standards As-
sociation for installation in the United States and Canada.

Provide packaged indoor heating units as Reznor
®
brand equipment. The units shall be Model LDAP (400, 800,
1200) arranged for ceiling suspension with vertical (down) air discharge. Each unit must have a single point
wall or roof penetration for exhaust of ue gases. Units shall be rated for 83% thermal efciency.
The cabinet shall be in one piece. Painted and ready to be suspended from ceiling by four suspension points
(or wall mounted), designed for ease of installation with an external 24-volt terminal strip and gas line connec-
tion.
Air supply will be directed by means of (2-way down discharge louvers) (4-way down discharge louvers) (30°
bend multi-positional discharge nozzles with 2-way louvers) (60° bend multi-positional discharge nozzles with
2-way discharge louvers) (30° bend multi-positional discharge nozzles with 4-way down discharge louvers).
The units shall include a propeller fan for each heat section with 3-speed 208/230 Volt open fan motor(s) with
internal overload protection, pressure switch to verify venter ow, resiliently isolated venter motor, resiliently
isolated axial fan and motor assembly, a high temperature limit control, a destratication fan control, and a
built-in disconnect switch. Operation shall be controlled through an integrated circuit board. The circuit board
monitors heater operation and has LED diagnostic indicator lights to identify abnormalities in control functions.
Unit shall have a single-stage (2-stage on size 400) gas valve eld adjustable for up to 10,000 ft/3,045 M eleva-
tion (high altitude pressure switch kit for units installed above 6,000 ft/1,830 M).
Units shall be equipped for use with (natural gas) (propane), (208/1) (230/1) supply voltage, multi-try direct
ignition with timed lockout.
Each heat section shall have the Reznor T
core
2®
heat exchanger and single burner combustion system. The
heat exchanger shall be of (aluminized steel) (409 stainless steel). The furnace shall be equipped with all
required safety elements.
The following shall be available (manual shutoff valve) (1” pipe coupling hanger kit) (24 volt thermostat) (mul-
tiple heater control) (thermostat guard) (vent cap).
Heaters shall be certied by the ETL Testing Agency for commercial and industrial applications.
