 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  (LPG  or  Natural).    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 an LPG container or propane cylinder.  LPG containers (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 
clearance combustibles and 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 conform with local building codes or, in the absence of local codes, with the National 
Fuel Gas Code, ANSI Z223.1/NFPA 54, or the Natural Gas and Propane Installation Code, CSA B149.1 In Canada, the 
installation must conform to current CSA B149.1 (The Natural Gas and Propane Installation Code) in the absence of 
local codes.  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, NFPA54 requires that 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  with  stacked 
materials,  sprinkler  heads,  gas  and  electrical  lines,  and  any  other  possible  obstructions  or  hazards.    Consideration 
also must be given to service accessibility.
