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. 

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.

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.

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.

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.

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.

To calculate the value ‘’: ( =  - )

• Measure the on site distance between bottom

of the heater and the floor = ‘’ inches (cm).

• Subtract the clearance below the heater ‘’

from ‘’ (see Table 1 for the value ‘’ that corre-

sponds to the model you are installing).

• Enter this value ‘’ 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 ‘’, ‘’ and ‘’.

It is recommended that a full heating design including heat loss calculation be conducted on

the structure or area to be heated. Heater sizing and placement must consider available

mounting height, sources of greatest heat loss, and the certified clearances to combustibles

with respect to stored material, moveable objects (cranes, vehicles, lifts, overhead doors, etc),

sprinkler system heads, and other obstructions on the site. Consideration must also be given to

vent / duct placement and the allowable combined lengths of vent and duct. Carefully survey

the area to be heated, and for best results place burner and combustion chamber in the coldest

area(s).

Installation must conform with all local, state, provincial and national code requirements includ-

ing the current latest edition ANSI Z223.1 (NFPA 54) in the U.S.A. and B149.1 installation

code in Canada, for gas burning appliances and equipment. The latest edition Electrical Code

ANSI/NFPA N0 70 in the U.S.A. and PART 1 CSA C22.1 in Canada must also be observed.

The heating system must have gas piping of the correct diameter, length, and arrangement to

function properly. For this reason, a layout drawing is necessary.

This heater must be mounted with at least the minimum clearances between the heater and

combustibles as shown in FIG-1, TABLE 1, Page 3. It is the installer’s responsibility to ensure

that building materials with a low heat tolerance which may degrade at lower temperatures are

protected to prevent degradation. Examples of low heat tolerance materials include vinyl sid-

ing, fabrics, some plastics, filmy materials, etc.

Positioning of lights, sprinkler heads, overhead doors, storage areas, gas and electrical lines,

parked vehicles, cranes and any other possible obstruction or hazard must be evaluated prior

to installation.
