This  heater  is  for  Indoor  Installation  and  Covered  Patio  Installation  only  and  can  be  used  in  either  Vented  or
Unvented  mode.  The  term  Unvented  actually  means  Indirect  Vented.  While  the  products  of  combustion  are
expelled  into  the  building,  national  codes  require  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.
R(B,S,M) S Series Only: Since straight tube heaters are always hotter at the control end than at the flue terminal
end,  always  observe  the  minimum  recommended  mounting  heights  shown  on  the  specification  sheets  and  in
Section  5.0)  of  this  manual.  Use  U-tube  configuration  instead  of  straight  tubes  for  spot  or  area  heating  (e.g.,
where a single heater is utilized for space heating).

High Altitude:
Appliances are supplied as standard for altitudes of O to 2,000 feet (0-610 m). High-altitude ratings are obtained
by a change in the orifice size. When ordered for high altitude installations, burners are supplied by the factory
ready for high altitude installation. Check the nameplate for altitude before proceeding with the installation. In
Canada the adjustment for altitude is made in accordance with Standard CGA 2.17, Gas-Fired Appliances for Use
at High Altitudes.
