Unit Start-Up
FOR YOUR SAFETY, READ BEFORE LIGHTING UNIT.
Do not use this furnace if any part has been underwater.
A flood-damaged furnace is extremely dangerous.
Attempts to use the furnace can result in fire or explosion.
Immediately call a qualified service technician to inspect
the furnace and to replace all gas controls, control
system parts, and electrical parts that have been wet or
to replace the furnace, if deemed necessary.
WARNING

shut off the manual gas valve to the appliance before
shutting off electrical supply.
WARNING

maintenance, turn the electrical power to unit OFF at

Never use tools. If the switch will not turn or if the control
switch will not move by hand, do not try to repair it.
Placing the Furnace into Operation

system. Do not attempt to manually light burners on these

ignition system.

or explosion may result causing property damage,
personal injury or death.
