LOCATION
Choose a location for unit installation taking into account the following guidelines.
• Unit must be installed indoors. Installation is not recommended in bathrooms, bedrooms or
occupied rooms that are normally kept closed.
• Unit should have proper clearance as indicated below including ample clearance in front of
unit for proper service access.
• Installation is recommended to be at a height that will allow easy viewing and operation of
the control panel.
• Heater requires a standard three prong, 120 V /60 Hz grounded AC power outlet within X feet
