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

distance 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 protected to prevent degradation.

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

appropriate model input/size.

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 24 inches (61 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.
