HE+ Series Infrared Gas Heater Installation and Operation Manual
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.
A “peel and stick” sign is provided with this heater (look in manual). Use a permanent
marker to record the required dimensions on the sign for the heater model installed.
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 in Figure 1 and Table 1
for the heater model being installed to get the
values for dimensions ‘S’, ‘F’ and ‘B’.
WARNING
Post this sign as instructed above.
It is the installer’s responsibility to ensure that building materials with a low heat toler-
ance which may degrade at lower temperatures are protected to prevent degradation.
Examples of low heat tolerance materials include vinyl siding, fabrics, some plastics,
filmy materials, etc.
