19. MULTIPLE TUBE HEATERS per THERMOSTAT

Each tube heater requires 120V, 60 HZ electrical power sized for 145VA. Maximum power
flow for internal 24V burner components is 21VA.

See previous page for internal wiring.

The heater must be electrically grounded in accordance with the National Electrical Code.
ANSI / NFPA 70 or current Canadian Electrical code CSA C22.1.
A maximum night set-back of 9°F (5°C) is recommended for optimum economy and comfort.
To maintain satisfactory comfort levels do not turn off the heating system over night/weekends.
