Connecting and Securing the Gas Hoses to the Burner
There are three gas hoses that are connected to the end cap on the burner assembly: the nebulizer oxidant
hose, the auxiliary oxidant hose, and the fuel hose. They are pointed out in the next figure. At this point,
all three hoses should be already connected to the burner. If they are not do so now. The next few
paragraphs discuss how to check them.
Figure 6- 4 Securing the gas hoses to the burner end cap.
The first hose is the nebulizer oxidant hose (also called the NEB). It is connected right after the nebulizer
is installed. The second gas hose is referred to as the auxiliary oxidant hose (AUX). It is the other "clear"
hose coming up from under the burner mounting plate and attached to the burner end cap. The hose is
connected at the factory. Confirm that it is connected and that the compression fitting is tight. If it is not,
do the following:
•
Tighten the compression fitting hand tight plus a ¼ turn using two wrenches: one wrench to hold
the nebulizer fitting and the other to turn the compression fitting.
The third hose connected to the burner is the fuel hose. It is the "clear" tubing attached to the burner end
cap. (Refer to figure Securing the gas hoses to the burner end cap.) That hose, too, is connected at the
factory. Confirm that it is connected and that the compression fitting is tight. If it is not, tighten it using
the procedure that follows:
•
Tighten the compression fitting hand tight plus a ¼ turn using two wrenches: one wrench to hold
the nebulizer fitting and the other to turn the compression fitting.
