Heater Expansion

It is a normal condition that during heat-up and cool-down a tube

heater will expand and contract. Allowances for heater expansion

must be made in the gas connection, venting and combustion air

ducting. Improper installation, alteration, or adjustment can result in

property damage, injury or death. Refer to Section 13

WARNING

Venting

Inadequate venting of a heater may result in asphyxiation, carbon

monoxide poisoning, injury or death. This heater may be directly or

indirectly vented from the space. Venting must be in accordance with

all local, state, provincial, and national codes (ANSI Z223.1/NFPA 54

in USA; B149.1 in Canada) and as indicated in this manual. Refer to Sections 11 & 12

Gas Connection

Improper installation, connection, or adjustment can result in property

damage, toxic gases, asphyxiation, injury or death. Using an ap-

proved flexible gas connector in the USA or Type 1 hose connector in

Canada, the gas supply to the heater must be connected and tested

in accordance with all local, state, provincial, and national codes (ANSI Z223.1/NFPA 54 in

USA; B149.1 in Canada) and as indicated in this manual. Refer to Section 13

WARNING

WARNING Start-Up ‘SMOKE’ Condition

During start up, the heating of material coatings used in the production process of tubes and

reflectors will create smoke during the initial period of operation. This condition is normal and

temporary .

Ensure that there is sufficient ventilation to adequately clear any smoke from the space.

Notify site and safety personnel to ensure that alarm systems are not unduly activated.

IMPORTANT THERMOSTAT SETTING FOR COMFORT

Infrared radiant (IR) heating system provide comfort with the effect of radiant heat and ambient

air heat.

If your IR system is controlled with a thermostat (TruTemp or ThermoControl Plus) that senses

radiant heat, then set the thermostat to the desired comfort temperature (ie: 65°; 68°; 20°C).

If your IR system is controlled with a standard 24V or 120V thermostat that senses only air tem-

perature, then start with a thermostat setting that is 5° to 7°F (3° to 5°C) lower than the desired

comfort temperature. Some trial and error setting may be required to ‘fine tune’ the comfort tem-

perature that best suits your site and provides most economical operation.

Clearance to combustibles

Location of flammable or explosive objects, liquids or vapors close to the heater may cause fire

or explosion and result in property damage, injury or death. Do not use, store or locate flamma-

ble or explosive objects, liquids or vapors in proximity of the heater.

The clearance to combustible material represents the minimum dis-

tance that must be maintained between the outer heater surface and

a nearby surface. The stated clearance to combustibles represents a

surface temperature of 90F° (50C°) above room temperature. It is the

installer’s responsibility to ensure that building materials with a low

heat tolerance which may degrade at lower temperatures are pro-

tected to prevent degradation. Examples of low heat tolerance mate-

rials include vinyl siding, fabrics, some plastics, filmy materials, etc.

In locations used for the storage of combustible materials, signs must be posted to specify the

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

the combustibles. Such signs must either be posted adjacent to the heater thermostats or in

the absence of such thermostats in a conspicuous location. In addition to stored or stationary

material, consideration must also be given to moveable objects such as cranes, vehicles, and

overhead doors, and structural objects such as sprinkler heads, electrical and gas lines, and

electrical fixtures.

It is beyond the scope of these instructions to consider all conditions that may be encountered.

Consult local authorities such as the Fire Marshall, insurance carrier, or safety authorities if you

are uncertain as to the safety or applicability of the proposed installation.

Refer to Figure 1 and Table 1 for the certified clearances to combustibles for the appro-

priate model input/size.

WARNING

WARNING Tube “GLOW”

It is a normal condition that the combustion tube (1st tube) can appear to “glow red”. For inputs

up to 150,000 Btuh, the top surface of the tube can appear red where heat is trapped between

the reflector and the tube. The stainless steel tube used for inputs 175,000 and greater can ap-

pear to entirely glow red. The tube material is designed into the heater because it can with-

stand the high temperature of combustion, and the “red glow” is a normal occurrence.

VENT END CLEARANCE: Clearances from the vent pipe are determined by local or national

installation codes, but must not be less than 6 inches (15 cm). For ‘unvented’ installation, a

minimum distance of 48 inches (122 cm) is required from the end of heater to a combustible

surface.

In locations used for the storage of combustible materials: Signs

must be posted specifying the maximum permissible stacking height to

maintain the required clearances from the heater to the combustibles.

The signs must be posted either adjacent to the IR heating system thermostats or in the ab-

sence of such thermostats, in a conspicuous place.

For your convenience a “peel and stick” sign

is provided with this heater. Use a permanent

marker to record the required dimensions on

the sign.

To calculate the value ‘H’: (H= T- C)

 Measure the on site distance between bottom of

the heater and the floor = ‘T’ inches (cm).

 Refer to Table 1 to get the value ‘C’ that corre-

sponds to the model you are installing

 Subtract the clearance below the heater ‘C’ from

‘T’ to get value ‘H’.

 Enter this value ‘H’ on the sign.

Refer to the information for the heater model

being installed in Figure 1 and Table 1 to get

the values for dimensions ‘S’, ‘F’ and ‘B’.

WARNING

Post this sign as instructed above.

NOTE that in the above table the clearances are measured from the reflector.

It is the installer’s responsibility to ensure that building materials with a low heat tol-

erance which may degrade at lower temperatures are protected to prevent degrada-

tion. Examples of low heat tolerance materials include vinyl siding, fabrics, some

plastics, filmy materials, etc.
