HEATING SYSTEM
Tubular Aluminized Steel Heat Exchanger
- Tubular heat exchanger is constructed of aluminized steel for superior resistance to corrosion and oxidation
- Curving design of heat exchanger allows complete exposure of heating surfaces to supply air stream
- Dimpled tubes with wrinkle bends allow for maximum heat transfer
- Compact design reduces space requirements in unit cabinet
- Heat exchanger has been laboratory life cycle tested
Inshot Burner Assembly

- Burner venturi mixes air and gas in correct proportion for proper combustion
- Burner assembly is removable from the unit as a single component for ease of service
Gas Control Valve
- 24 volt redundant combination gas control valve combines manual shut off switch (On-Off), automatic electric valve (dual) and gas pressure regulation into a compact combination control
Combustion Air Inducer
- Prepurges heat exchanger and safely vents combustion products
- Operates only during heating cycle
- Blower motor has ball bearings and is thermally protected
Pressure Switch
- Pressure switch prevents unit operation in case of blocked flue outlet
Limit Control(s)
- Factory installed and accurately located
- Limit control has fixed temperature setting and protects heating system from abnormal operating conditions
