outlet. It should always slant slightly upwards. For best results, is should rise straight up. The venting
system shall be in accordance with the National Fuel Gas Code, ANSI Z223.1 /
B149.1, Natural Gas and CSA B149.2, Propane Installation Codes, and local codes.

NOTE: DO NOT PUT A DAMPER IN THE FLUE AND DO NOT CONNECT A BLOWER DIRECTLY TO
THE FLUE.

If the flue runs directly to the free air outside the building, use a wind deflector or a UL listed vent cap at the
end

of the pipe. Termination of the vent must be at least two feet above the highest part of the roof within ten

feet. REF: AGA CATALOG NO. XH0474.

H. BURNER OPERATION:

The oven burner flame should always have a blue appearance. This indicates a good mixture of air and gas.
When using LP gas, the flame will have a blue-yellow appearance. There may be intermittent yellow-orange
flame noticed. This is caused by dust particles burning in the flame.
