This heater is for Indoor Installation only and can be used in Unvented mode. The term Unvented actually
means Indirect Vented. While the products of combustion are expelled into the building, national codes
require 4 CFM/1000 BTU of heater input ventilation in the building to dilute these products of combustion.
This ventilation may be provided by gravity or mechanical means.
This heater is not an explosion proof heater. Where the possibility of exposure to volatile and low flash point
materials exists, it could result in property damage or death. This heater must not be installed in a spray
booth where the heater can operate during the spraying process. Consult your local fire marshal or insurance
company.
Certain materials or objects, when stored under the heater, will be subjected to radiant
heat and could be seriously damaged. Observe the Minimum Clearances to Combustibles listed in the
manual and on the heater at all times.

MINIMUM CLEARANCES TO COMBUSTIBLES
For maximum safety the building must be evaluated for hazards before installing the heater system.
Examples include, but are not limited to:
Gas and electrical lines
Combustible and explosive materials
Chemical storage areas
Areas of high chemical fume concentrations
Provisions for accessibility to the heater
Adequate clearances around the openings
Combustion and ventilating air supply
Vehicles parking areas
Vehicles with lifts or cranes
Storage areas with stacked materials
Lights
Sprinkler heads
Overhead doors and tracks
Dirty, contaminated environment
A critical safety factor to consider before installation is the clearances to combustible materials. Clearance to
combustibles is defined as the minimum distance you must have between the infrared surface, or reflector,
and the combustible item. Considerations must also be made for moving objects around the infrared heater.
The following is a partial list of items to maintain clearances from:
