OR

EXPLOSION

HAZARD

Failure to follow this warning could result in personal injury,

death, and/or property damage.
Turn OFF electric power (at disconnect) and gas supply (at

manual valve in gas line) when installing orifices. Installation

of orifices requires a qualified service technician.

!

WARNING

NOTE:

Main burner orifices can be changed for high altitudes.

1. Disconnect gas line from gas valve.
2. Remove manifold from furnace.
3. Remove the orifices from the manifold and replace them

with properly sized orifices.

4. Tighten orifices so it is seated and gas tight. (See Fig. 39.)
