For G6 & L1 Series Furnaces
• Designed for Canadian installations. To convert a natural gas
furnace to LP/Propane gas for altitudes between 0 to 4,500
feet above sea level, the main gas orifice must be replaced.
For higher altitudes (between 2,000 & 4,500 feet above seal
level) the input must be de-rated by 10%. This can be done
by simply reducing the manifold pressure without changing
the gas orifices.
• Use on standard & slow opening models only
• Not for use with step regulator valves
