Claim:
A modular burner/blower system, comprising: (a) an independently operable direct fired burner unit comprising: (i) a burner casing; and (ii) a direct fired burner mounted within said burner casing; and (iii) heating components and controls including a discharge air sensor to monitor the temperature of discharge air, an airflow switch to insure proper airflow during burner operation that shuts off the burner when the airflow is incorrect, an outside air thermostat to automatically turn the heater circuit on when the outside air temperature falls below a predetermined level, an air flow pressure probe, an inlet gas pressure port to enable measurement of inlet gas pressure when the burner is locked in high fire, a combination gas valve, a modulating gas valve to provide the desired discharge air temperature, a burner gas pressure port, a manual gas shut off valve, a temperature dial to enable users to adjust the discharge air temperature, and a starter/overload contactor to provide overload protection; and (b) an independently operable blower unit comprising: (i) a blower casing configured to interconnect with the burner casing; and (ii) a blower mounted within the blower casing.
