1. GENERAL INFORMATION

INSTALLER: This manual is the property of the owner. Please present this manual to the owner when you leave

the jobsite.

This heater is a self-contained infrared radiant floor model heater for use in locations where flammable gases or vapors

are not generally present and is intended for the heating of non-residential spaces.

INSTALLATION REQUIREMENTS

nstallation of this heater must be in accordance with all applicable codes shown in the instructions and/or the local

codes and authorities having jurisdiction. Heaters shall be installed by a licensed contractor or licensed installer.

Clearances to combustibles as outlined in this manual should always be observed.

Every heater shall be located with respect to building construction and other equipment so as to permit access to the

heater. Each installer shall use good installation practices when locating the heater and must give consideration to

service accessibility.

This heater is for INDOOR INSTALLATION ONLY. While the products of combustion are expelled into the building,

national codes require ventilation in the building to dilute these products of combustion. This ventilation may be

provided by gravity or mechanical means. Refer to Section 9 of this manual for minimum requirementsfor ventilation

and combustion air.

specific work area. This is ordered as an accessory item, Part No.

04310010.

INSTALLATION INSTRUCTIONS

1. Loosen and remove the 1/2-13 hex nut

and washer from the heater assembly.

2. Lift the head from the heater.

3. Place reflector on outside of expanded

metal guard with bottom edge inside lip

WARNING:KEEP PERSONNEL AND COMBUSTIBLE MATERIAL AT LEAST 12 FT. FROM

HEATER MODEL RFPA25 WHEN IN OPERATION.

6. GAS CONNECTIONS AND REGULATION

1. Connect to the supply tank or manifold in accordance with the latest edition of National Fuel Gas Code

(ANSI Z223.1) and local building codes. Authorities having jurisdiction should be consulted before the

installation is made.

2. Pipe joint compounds must be resistant to the action of liquefied petroleum gases.

3. Where local codes do not prohibit, an A.G.A. or U.L. approved flexible connection is recommended between the

rigid piping and the heater. A union and an approved shut-off valve should be installed before the control valve

inlet. The shut-off valve should be installed within 6 feet of the union.

4. This appliance is equipped with a manual gas valve and a pilot regulator. The maximum supply

pressure to the appliance is 5 PSIG. If the line pressure is more than the maximum supply

pressure, then use a line regulator which corresponds to the supply pressure.

5. The pilot burner is regulated separately to operate at 11.0”W.C. The pilot flame can be reduced by turning the pilot

valve handle counterclockwise should this be desired.

6. After gas connections have been made, make sure the heater and all gas outlets are turned off before the main gas

supply is turned on. Turn the gas pressure on and check for leaks. To check for leaks, apply a solution of soap

suds to all connections and joints or check by one of the methods listed in Appendix D of ANSI Z223.1 (latest

edition) Natural Fuel Gas Code. DO NOT USE AN OPEN FLAME OF ANY KIND TO TEST FOR LEAKS.

Form 41358010

July 06

7. INSTRUCTIONS FOR PRESSURE TEST GAUGE CONNECTION

Supply Pressure: Installer to provide a 1/4" N.P.T. plugged tapping, accessible for test gauge connection

immediately upstream of the gas supply connection to the heater.

Manifold Pressure: Turn gas valve to "OFF" position. Remove 1/4" plug from manifold downstream from the manual

ball valve and connect 1/4" nipple to the tapped hole. Connect gauge to nipple. Turn on the gas supply.

With the main burner operating, check burner manifold pressure using a pressure gauge suitable for the operating

pressure of the heater. If adjustment is required, remove cover screw of the appliance regulator. Using a small

screwdriver, turn adjustment screw clockwise to increase or counter-clockwise to decrease gas pressure to

burner. Replace cover screw.

8. INFORMATION FOR LP GAS FLOOR MODEL HEATERS ONLY

Heaters used with LP gas must be installed in accordance with the latest edition of the National Fuel Gas Code -

NFPA54, Standard for the Storage and Handling of LP Gas - NFPA 58, all state and local codes or the authority having

jurisdiction.

This heater is intended for industrial or construction heating and it must never be used for residential/domestic heating.

WARNING:A single stage regulator must be installed on the tank or cylinder to reduce the tank or

cylinder pressure to the heater. Operation of this heater without this regulator can cause damage to

the heater and personal injury.

The heater must be connected to the tank or cylinder by a UL Listed hose assembly or hard piping. A 25 foot

assembly of UL Listed hose is available from Space-Ray under Part No. 42035020. A single stage LP gas regulator

(operation range: 250 PSIG maximum inlet and 5 PSIG outlet) is available as Part No. 03483140.

The volume of a given quantity of liquid LP gas in a container is directly related to its temperature. As a result, the

vaporization rate of a tank or cylinder will decrease as the temperature drops and as the percentage of liquid in the

container becomes smaller.

WARNING: Due to the continuous length of time the heater might be in operation, Space-Ray DOES NOT

recommend the use of a 100 lb. cylinder with the RFPA25 heater because of the large BTU input. Manifolding

several cylinders together is a practical way of increasing the time of operation of these heaters. Operation of

the heater with insufficient sized cylinders or when the liquid level becomes too low will result in poor heater

performance and can cause sooting. Consult your LP gas dealer for proper sizing of container.

Always turn the gas off at the tank or cylinder when the heater is not in use. When in operation, keep the heater a safe

distance from the LP gas container and combustible materials as indicated on the heater and in the instructions.

Fasten LP cylinders securely so they cannot be knocked over.

9. VENTILATION AND COMBUSTION AIR

This heater requires ventilation in the building to dilute the products of combustion and provide fresh air for

efficient combustion. The minimum recommended vent flow required is as follows:

RFPA25: 1000 cfm

The combustion air enters through the heater base and must not be restricted. DO NOT block or enclose any part

of the heater base. All ventilation in the building must be at a level above the height of the heater.

10.LIGHTING AND SHUTDOWN INSTRUCTIONS

MODELS WITH IGNITION SUFFIX "-6A"

1. Turn manual burner valve handle to “OFF”position. Push in silver button on safety valve and light pilot. Hold

button in firmly for approximately 30 seconds or until pilot remains lighted without holding button in. If air is in

line, it will take a few minutes for gas to reach pilot.

2. Turn manual burner valve handle to full “ON”position. Sooting will

occur if this heater is operated with the valve handle in any

position except full “ON”.

3. If heater does not light, shut off gas completely for five minutes

before attempting to relight.

4. To turn off main burner and pilot gas, turn manual burner and pilot valves to “OFF”position.

CAUTION: DO NOT OPERATE MAIN BURNER AT ANY SETTING LESS THAN FULL "ON" POSITION.

SOOTING WILL OCCUR!

11. CLEANING AND ANNUAL MAINTENANCE

This heater must be cleaned and serviced at least once before the start of each heating season or at any time the

infrared emitter show signs of collecting any foreign material on its surface. Maximum heating efficiency and clean

combustion will be maintained by keeping the emitter and burner clean. To clean the heater follow these instructions:

1. Turn off the gas supply to the heater.

2. Remove and clean the burner, burner tube and orifice. Clean these components as required to provide a free

passage of air and gas.

3. If the emitter shows any accumulation of material in the ports, remove the heater top and the expanded

metal guard to expose the emitter and use a high pressure air hose to blow the ports clean. If this does

not clean the holes, remove the four (4) screws holding the emitter to its mounting ring and remove the

emitter so that it can be cleaned both inside and out with a wire brush and then blown out with a high

pressure air hose.

4. Inspect the pilot burner and remove any foreign material with a brush or an air hose.

5. Reassemble the heater, test all connections for leaks and test the heater to be sure it is now operating properly.

12. REPLACING PARTS

At all times when parts are being replaced, ensure that both gas and electrical supplies are disconnected.

Various parts are available from the factory for replacement by a licensed service person. Refer to exploded parts

guide in Section 13 for all replacement parts.
