<br /> "CSA rating for altitudes to 2000 ft.
<br /> e Size shown is for gas connection to a single stage gas valve,not supply line size.
<br /> °Smaller and/or larger vent and combustion air pipe diameters may be allowed;refer to the Venting Installation Manual for Separated Combustion
<br /> Units,Form I-V-SC.If vent diameter is different from vent connection,reducer/enlargers will be field-required.
<br /> °MOP=2.25 x largest motor FLA+remaining load.Answer is rounded down to the next size of commercially available circuit breaker or fuse.
<br /> "Ail other information in this table is based on a heater equipped with a standard 115 volt open fan motor.
<br /> For installations where dirt,dust,and other air borne contamination is present in the Indoor environment,it is
<br /> recommended to use separated combustion units(Model UDAS).These models use air from outside the space
<br /> forcombustion.This will help reduce the build up of contaminates on the burnerwhich would affect the combus-
<br /> tion process.Refer to the Installation manuals for recommended frequency of maintenance and cleaning.
