PROPER BURNER FLAME
The burner flame may be observed through the sight glass
located in the burner box cover. See Figure 11. A proper
flame will have a dark blue inner mantle, with a lighter blue
outer mantle that extends from the burner into the heat
exchanger tube, (see Figure 12). There is no primary air
adjustment on the burner, and proper flame is assured since
the correct manifold pressure and orificing has been done
at the factory for elevations up to 2,000 feet.

BURNER ORIFICE
This heater is orificed at the factory for elevations up to
2,000 ft. If installed above 2,000 ft., the BTU input must
be reduced 4% per 1,000 ft. See the following orifice chart
for the proper orifice for a specific elevation.
