WARNING
To avoid bodily injury, fire or explosion, solvent cements MUST be kept away from all
ignition sources (i.e. sparks, open flames and excessive heat) as they are combustible
liquids. Avoid breathing cement vapors or contact with skin and/or eyes.
WARNING
High Voltage – Disconnect ALL electrical power and shut off gas supply before servicing
or installing. Multiple power sources may be present. Failure to do so may cause property
damage, personal injury or death.
WARNING
If the information in these instructions is not followed exactly, a fire or explosion may result
causing property damage, personal injury or loss of life.
Do not store or use gasoline or other flammable vapors and liquids in the vicinity of this or
any other appliance.
What to do if you smell gas:
• Do not try to light any appliance.
• Do not touch any electrical switch; do not use and phone in your building.
• Immediately call your gas supplier from a neighbor's phone. Follow the gas supplier's
instructions.
• If you cannot reach your gas supplier, call the fire department.
• Installation and service must be performed by a qualified installer, service agency or the
gas supplier.
WARNING
To avoid property damage, personal injury or death due to explosion or fire, install a gas detecting
warning device. Since the odorant in propane gas can be reduced by iron oxide (rust), a gas
detecting warning device is the only reliable method to detect propane gas leaks.
WARNING
Property damage, furnace malfunction, personal injury or death may result from improper
installation or maintenance performed by untrained personnel. Installation must conform with
local codes, with codes of the country having jurisdiction. Call your installing dealer or other
qualified service companies to perform the installation or maintenance inspection.
WARNING
To avoid the risk of property damage, personal injury or fire, shut off gas supply first, then
disconnect the electrical supply before proceeding with the kit installation.
