Read and understand, the installation, operating, and maintenance instructions
thoroughly before installing or servicing this equipment.
Only trained, qualified gas installation and service personnel may install or service this
equipment.
Design
OHP Series Patio Heaters are designed specifically for comfort heating in an outdoor environment. Examples
of suitable applications include patios, porches, outdoor shopping areas, and outdoor pathways. When used
properly, the heaters will increase the comfort levels of its application. However, the effectiveness of the
heating will depend on many variables such as air temperature, wind velocity, wind barriers, mounting
heights, and distance between heaters. To ensure a safe, properly designed heating system, all of these
variables should be considered prior to developing a layout for the infrared heaters.
It is important to note that the effectiveness of the heater may be diminished in environments with wind
velocities above 5 MPH. Wind barriers can be extremely effective in maintaining the effectiveness of the
heater and reducing the operational costs. However, if wind barriers are used, they must be designed in
such a way that allows for the necessary fresh air and ventilation for the proper heater operation. In addition,
all clearance to combustibles must be maintained at all times (See Chart 1.1 on page 5).
The infrared patio heaters may be laid out in a number of configurations depending on the structures
constraints of the application, heating requirements and, therefore, the basic recommendations of installation.
The minimum mounting height for all OHP Series Patio Heaters is 6.5 feet above the finished floor.
The heater must always be operated in a location that allows uniform air pressure around the heater. If one
part of the heater is located outside of a wind protected zone, the heater may not properly function or
damage to the heater may occur. Consideration should be taken on how the wind will affect the heaters after
installation. IMPORTANT: Fire sprinkler heads must be located at an appropriate distance from the heater
to avoid accidental discharge of the fire suppression system. This distance may exceed the published
clearance to combustibles (see Chart 1.1 on pg. 5). Certain applications will require the use of high
temperature sprinkler heads or relocation of the heaters.
NOTICE
Radiant heat is capable of damaging or destroying certain materials or items. Do not store materials or
items underneath the heater. Always maintain clearance to combustibles.
Fire sprinkler systems containing propylene glycol, antifreeze, or other potentially flammable substances
shall not be used in conjunction with this heater without careful consideration for, and avoidance of,
inadvertent discharge hazards. For further information, consult NFPA 13. Always observe applicable
state and local codes.
