This heater is a self-contained infrared radiant tube heater designed for use where flammable gases or vapors

are not generally present.

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

local codes and authorities having jurisdiction. In the UK all equipment must be installed and maintained in

accordance with the relevant provisions of the Gas Safety (Installations and Use) Regulations 1998 for gas fired

products. Installation practices must take into account the Health and Safety at Works Act 1974 or relevant

codes of practice. In addition the installation must be carried out in accordance with the current IEE wiring

regulations (BS 7671-latest revision), BS 6896-latest revision (Industrial & Commercial) and any other relevant

British Standards and Codes of Practice by a qualified installer. All external wiring MUST comply with the current

IEE wiring regulations.

Clearances to combustibles as outlined in the manual should always be observed. In areas used for storage of

combustible materials where they may be stacked below the heater, the installer must post signs that will

“specify the maximum permissible stacking height to maintain the required clearances from the heater to

combustibles.”

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

to the control housing. Each installer shall use skillful and reliable installation practices when locating the

heaters and must give consideration to service accessibility.

The term Unvented actually means Indirect Vented. 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

must be provided by gravity or mechanical means. Ventilation requirements are addressed further in these

instructions.

Before installation, check that the local distribution conditions, nature of gas and pressure, and adjustment of

the appliance are compatible.

Although these heaters may be used in many applications other than space heating (e.g., process heating),

Space-Ray will not recognize the warranty for any use other than space heating.

This heater is not an explosion proof heater.

This heater is not an explosion proof heater.This heater is not an explosion proof heater.

This heater is not an explosion proof heater. Where the possibility of exposure to volatile and low flash point

materials exists, it could result in property damage or death. This heater must not be installed in a spray booth

where the heater can operate during the spraying process. Consult your local fire marshal or insurance company.

8.0) TYPICAL SUSPENSION METHODS

Not with standing their limited scope, the appliance should be installed in accordance with the relevant

provisions of any National Gas Safety (Installation and Use) Regulations. Due account should also be taken of

any obligations arising from any National Health and Safety at Work Regulations, National and Local Building

Regulations and National Electrical Wiring Regulations. The appliance must be installed, and where necessary,

converted for use on other gases, by a qualified installer.

Burner must be secured to the mounting flange with nuts.

All materials used to suspend the heater must have a minimum working load

of 52kg.

All S Hooks must be crimped closed.

Never use the heater to support a ladder or other access equipment.

Failure to do so may result in death, serious injury or property damage.

CRUSH HAZARD

Various means of suspending the heater can be used. See the following drawings for typical examples.

a. Use only noncombustible materials for suspending hangers and brackets.

b. Linear Tube He

Linear Tube HeLinear Tube He

Linear Tube Heaters

atersaters

aters should be suspended to provide a slope of 0.25 degree up

upup

up to the fan (25 to 50mm). The

appliance should be located with respect to building construction and other equipment to permit access to

the appliance for servicing etc.

c. Turnbuckles can be used with chains to allow leveling of the heater. All “S” hooks and eye bolts must be

manually crimped closed by the installer.

d. For suspending the appliance it is recommended that suitable protected welded chain (Ø 3mm x 65 links

per m) or Ø 8mm min mild steel drop rods and suitable brackets are used. Attach the chains or drop rods to

the hanger brackets where shown providing at least Ø 5mm closed link hooks are used chains may be

attached directly to the hanger brackets.

e. Heaters subject to vibration must be provided with vibration isolating hangers.

f. Heaters must not be supported by gas or electric supply lines and must be suspended from a permanent

structure with adequate load capacity.

g. Hanging points are fixed along the length of heater to accommodate trim pieces. Secondary steel work may

be required to span between supporting beams.

h. The appliance should be located with respect to building construction and other equipment to permit access

to the appliance for servicing etc.

Space-Ray recommends that the body sections be suspended using chains with turnbuckles. This will allow slight

adjustments after assembly and heater expansion/ contraction during operation.

If a “trapeze” method is used for tube support/hanger brackets (shown below), the minimum chain length for the

two connecting chains is 914 mm to minimize any vibration that might be generated by the draft inducer

assembly. If these chains must be less than 914 mm, then do not use the trapeze method and, instead, use

individual chains on each tube support/hanger bracket.

8.1) BURNER BOX SUPPORT DETAILS

1. The burner box must be supported with welded chain (Ø 3mm x 65 links per m) or Ø 8mm min mild steel

drop rods and suitable brackets after overall heater suspension is complete. This is to prevent burner from

sagging which may cause the tube to burn out. Assemble bracket and turnbuckle to inlet end of burner as

shown.
