SPECIFICATIONS

Portable Electric Heaters

Suspended Electric Heaters

Description

Fostoria portable and suspended electric heaters provide clean, quiet, odor-free, fan-forced heat. They are designed to circulate room air continuously; gradually heating a confined space. The best results will be obtained when using  these heaters in smaller, insulated spaces. Features include a safety-yellow enclosure with front and rear safety screens; reliable stainless steel finned heating elements; a high-limit temperature switch with automatic reset; an automatic thermostat control with fan-only option; and a long-life motor and fan assembly with sealed bearings. The portable (FES) models come mounted on a two-wheeled cart with wheels designed to be easily pushed or pulled over uneven surfaces.

FES Models

All Fostoria FES models come fully assembled except the handle is attached in a lowered shipping position when shipped from the factory. The dimensions above are for handle in operating position. See page 5 for final assembly of handle.

INSTALLATION

ALL Fostoria YES models require some assembly. Four steps are required to complete the assembly and installation.
Tools required: (2) ¾” socket or box wrenches.
Parts required: the two screws required to secure wall/ceiling bracket to a suitable surface are not supplied with heater. You must use 5/16” bolts and flat washers to mount this bracket.

1. Step 1: Install (1) side rotating stop over bolt and into curved slot (as shown at right) on each side of heater.
2. Step 2: Assemble hanger to heater per hanger assembly detail. No tools are required.
3. Step 3: Secure wall/ceiling mounting bracket to appropriate surface that will support a min. weight of 100 lbs continuously.
   NOTE: all mounting hardware to mount hanger to wall/ceiling bracket is supplied with heater.
4. Step 4: Assemble unit to mounting bracket following the instructions of chosen mounting option below.

WARNING

FALLING OBJECTS HAZARD
FIRE HAZARD

ASSEMBLY

Tools Required: (2) 7/16” socket or box wrenches.
To position the handle at operating height:

1. Step 1: Remove and keep the hardware securing the\ handle to the legs.
2. Step 2: Raise handle until holes align with the upper holes in the legs.
3. Step 3: Re-insert hardware as shown, and fasten securely.

WIRING

THE PROPER SIZE SO- type feeder cable MUST BE USED for the electrical hook-up of this heater. The proper cable size is shown in the tables below (A.W.G./ # of conductors.) Table 1 is for cable 50ft. in length or less. Table 2 is for cable longer than 50ft.

A 25ft. cable kit can be purchased from the factory. Refer to the kit part numbers in table at right.
CABLE KITS INCLUDE:

• 25 feet of Type SO cable, with either 3-conductors or 4-conductors, depending on the heater requirements.
  To order cable kits
  Phone: 1-800-495-4525

• Feeder cable or cable kit assembly MUST BE made by licensed electricians ONLY.
• Service panel or receptacle used to supply power to these heaters MUST have a ground bus or ground pole that is securely bonded to earth ground.
• Connect green ground conductor on feeder cable or cable kit to grounding lug on heaters.
• Comply with ALL local electrical codes and the National Electric Code (NFPA70) when providing electrical power to these heaters.

ELECTRICAL SHOCK HAZARD FIRE HAZARD

• Serious injury or death may occur
• Disconnect from the electrical supply before installing feeder cable to these heaters.
• Read and follow all safety information in box to the left.

FES-1024-1CA, FES-0924-1C

Models FES-1024-1CA and FES-0924-1C are shipped with a corset factory installed. This corset contains a plug for use with a 50A household range receptacle. The blade configuration on the plug included on these heaters is represented in fig. 1 below (4-wire circuit).
The range receptacle you choose to use may have a blade configuration compatible with the plug shown in fig. 2 (3-wire circuit). This is an older branch circuit design that does not include a separate equipment grounding conductor (green wire). The configuration in fig. 1 has been implemented on newer branch circuit installations for increased safety, and is now the required circuit configuration by the National Electric Code. Changing a 3-wire branch circuit and receptacle to a 4-wire design may involve changes to your range and must only be done by a licensed electrician.

ELECTRICAL SHOCK HAZARD fig. 1 fig. 2

• Serious injury or death may occur.
• Plug heater into a 4-wire receptacle rated 50A.
• Any and all changes to branch circuits and receptacles MUST be done by a licensed electrician ONLY.

3-Phase Models
Attach feeder cable or cable kit to heater as shown in the photograph at left for the following 3-phase models.

OPERATING INSTRUCTIONS

Fostoria FES and YES series heaters are designed to circulate room air across their heating elements to gradually increase room temperature. The best performance results will be obtained when using these heaters in smaller, confined spaces with low ceilings.
The operation of these heaters is accomplished via the use of a multi-function thermostat (refer to diagram below).

You have the option to use the fan only*, or the fan and heating elements together. Position the knob pointer in the “fan-only” area to circulate room air with no heating. Move the pointer into the “heat” area to energize the heating elements and set the thermostat.
Maximum heating is obtained with knob turned fully clockwise**. Both fan and elements are off when the knob is turned fully counterclockwise.
Allow the fan to operate for a minimum of 3 minutes when you are done using the heater to purge heat from the unit.
*The thermostat has a preset range of 40˚F to 100˚F. If the ambient room temperature is below 40˚F, there will be no “fan only” function as the thermostat is always calling for heat.
**Setting the thermostat to high heat versus low heat does not make the unit operate at a higher temperature. It simply raises the temperature necessary to satisfy the thermostat. The unit will run longer to try to satisfy a higher thermostat setting.

Note: ALL FES/YES models are equipped with an internal over temperature limit designed to protect your heater if a restricted airflow condition occurs. This limit device will completely shut down the heating elements if the temperature limit is reached. The limit will automatically reset when the unit cools.
