HE+ Series Infrared Gas Heater Installation and Operation Manual
6. MOUNTING CLEARANCES
This heater must be mounted with at least the minimum clearances between the heater and
combustibles as shown in Figure 1 and Table 1. 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 materials include vinyl siding,
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.
Ensure adequate clearance around the air intake at the burner to allow sufficient com-
bustion air supply to the heater.
Guidelines for heater placement refer to Table 2.
SERVICE CLEARANCE TO BURNER: The lower ‘jaw’ of the burner cabinet swings down to
provide convenient service access to burner components. Provide a minimum clearance from
any wall or obstruction of 24 inches (610 mm) to the access end of the burner housing (refer to
Figure 2) - the minimum clearances to combustibles must always be maintained above, below,
and to the sides of the tube/reflector system.
