 SAFETY REQUIREMENTS 

 

The heater area must be kept clear and free from combustible materials, gasoline and other flammable vapors 
and liquids. 

 

This heater is designed for  use with  one type of gas (G20, G31, etc.).   Make sure that the type of gas to  be 
supplied to this heater matches that shown on the heater rating plate. 

 

DO  NOT  install  this  heater  directly  onto  a  propane  container  or  propane  cylinder.    Propane  containers  or 
propane cylinders must not be stored indoors or in the vicinity of any gas-burning appliance. 

 

DO NOT Store flammable materials near the heater. 

 

DO NOT locate gas and electric supply lines directly above the heaters path of flue products. The path of flue 
products will change if an optional low clearance heat shield is installed. 

 

Children  and  adults  should  be  alerted  to  the  hazards  of  high  surface  temperatures  and  should  stay  away  to 
avoid burns or clothing ignition. 

 

Young Children should be carefully supervised when they are in the area of the heater. 

 

DO NOT spray aerosols or flammable materials in the vicinity of this appliance while it is in operation. 

 

Clothing or other flammable materials should not be hung from the heater or placed on or near the heater. 

 

NEVER attempt to service the heater while it is plugged in, operating or hot.   

 

Any  guard  or  other  protective  device  removed  for  servicing  a  heater  must  be replaced  prior  to  operating  the 
heater. 

 

DO NOT Install the heater in a recess, alcove or enclosure. 

 

Installation and repair should be done by a licensed contractor qualified in the installation and service of gas 
heating  equipment.  The  heater  should  be  inspected  before  use  and  at  least  annually  by  a  qualified  service 
person.  More frequent cleaning may be required as necessary. It is imperative that the control compartment, 
air passageways and burner of the heater be kept clean. 

 

If any changes are made to the patio or building structure after the heaters are installed such as adding plastic 
curtains  to  enclose  the  patio  the  modified  design  must  be  checked  by  a  qualified  person  to  ensure  that the 
ventilation requirements are maintained. 

 

DO NOT paint any surface of the heater. 

 

DO NOT throw objects at the heater. 

 

Avoid  inhaling  fumes  emitted  from  the  heater’s  first  use.  Smoke  and  odor  from  the  burning  of  oils  used  in 
manufacturing will appear. Both the smoke and odor will dissipate after approximately 30 minutes. 

INSTALLATION REQUIREMENTS 
Installation  of  this  heater  must  be  in  accordance  with  all  applicable  codes  shown  in  the  instructions  and/or  the 
local  codes  and  authorities  having  jurisdiction.  In  the  UK  all  equipment  must  be  installed  and  maintained  in 
accordance  with  the  relevant  provisions  of  the  Gas  Safety  (Installations  and  Use)  Regulations  1998  for  gas  fired 
products. Installation practices must take into account the Health and Safety at Works Act 1974 or relevant codes 
of practice. In addition the installation must be carried out in accordance with the current IEE wiring regulations BS 
7671-latest  revision,  BS  6896-latest  revision  (Industrial  &  Commercial)  and  any  other  relevant  British  Standards 
and  Codes  of  Practice  by  a  qualified  installer.  All  external  wiring  MUST  comply  with  the  current  IEE  wiring 
regulations. Heaters shall be installed by a licensed contractor or licensed installer. 
 
Clearances to  combustibles as outlined in  this  manual should always be observed.   In areas used for storage of 
combustible materials where they may be stacked below the heater, the installer must post signs that will “specify 
the maximum permissible stacking height to maintain the required clearances from the heater to combustibles.” 
 
Every heater shall be located with respect to building construction and other equipment so as to permit access to 
the  heater.  Each  installer  shall  use  quality  installation  practices  when  locating  the  heater  and  must  give 
consideration to clearances to combustible materials, vehicles parked below, lights, overhead doors, storage areas
