Note:  Ensure  clearances  are  in  accordance  with 
local  installation  codes  and  the  requirements  of 
the  gas  supplier.  Dégagement  conforme  aux 
codes  d’installation  locaux  et  aux  exigences  du 
foumisseunde  gaz.

 

Due  to high  surface  temperatures,  locate the  unit 
out  of  traffic  areas  and  away  from  furniture  and 
draperies.  Do  not  place  clothing  and  other 
flammable  material  on  or  near  the  heater.  When 
positioning  the  unit  always  maintain  adequat e  
ventilation.  Minimum  clearances  to combustibles  
must be maintained  as shown  in Figures  5  - 8.

 

 

Note:

  The  rear  clearance  to  combustibles  is 

determined  by  either  the  unit’s  or  the  vent  pipe’s  
minimum  clearance,  depending  on  whether  the 
installation  calls for  vertical  rise  within  the  room  or  a 
rear  exit,  through-the-wall  vent  pipe.    Ensure  you 
consider  the  need  for  access to the gas control  valve 
access  door  on  the  front  of  the  unit  as  well  as  full 
access  for  periodic  cleaning  and  servicing.  Also 
consider  clearance  for  the  blower  assembly  if 
present,  or planned  in the future
