1. Use this unit only in the manner intended by the manufacturer. If
you have questions, contact the manufacturer at the address or
telephone number listed in the warranty.
2. Before servicing or cleaning unit, switch power off at service panel

means cannot be locked, securely fasten a prominent warning
device, such as a tag, to the service panel.
3. Installation work and electrical wiring must be done by a qualified
person(s) in accordance with all applicable codes and standards,
including fire-rated construction codes and standards.
4. Sufficient air is needed for proper combustion and exhausting of
gases through the flue (chimney) of fuel burning equipment to
prevent backdrafting. Follow the heating equipment
manufacturer's guideline and safety standards such as those
published by the National Fire Protection Association (NFPA),
and the American Society for Heating, Refrigeration and Air Con-
ditioning Engineers (ASHRAE), and the local code authorities.
