bothsides,aboveandbehindtheburnerforremoval.
• Provideaminimumof18inchesofclearancebetween
burnersandbuildingwalls.(Alwaysobserveminimum
clearancestocombustibles.)
• Besuretheheaterhasadownwardpitchofone-half

Horizontal Venting
This heater, when horizontally vented, must be installed with the
approved venting system. For horizontal venting installations these
tube heater are certified as a category III appliance.
This heater, when vertically vented, must be installed with the
approved venting system. For vertical vent installations, ER2STG
60-100 model and ER2STG 80-125 model are category I
appliances. The ER2STG 125-175 model is only Category I when
vented vertically with 6" (15.25cm) diameter vent pipe.

HIGH ALTITUDE
Heaters may be fired at full input up to 2000 ft. (610m) above sea level. Above 2000 ft. (610m) a high altitude conversion kit may be required
to ensure proper burner performance, please consult the manufacturer. Be prepared to answer factory questions regarding: type of fuel for the
proposed appliance conversion, gas pressure available at site, and specific altitude at site. The conversion shall be carried out by a
manufacturer’s authorized representative, in accordance with the requirements of the manufacturer, provincial, or territorial authorities having
jurisdiction and in accordance with the requirements of the CSA B149.1 or CSA149.2 installation codes.
