Read these instructions carefully. Failure to follow them 
could damage the product or cause a hazardous
condition.

Check the ratings given in the instructions and on the 
product to make sure the product is suitable for your 
application.

Installer must be a trained, experienced, flame safeguard 
control technician.

After installation is complete, check out product opera-
tion as provided in these instructions.

Follow instructions provided by burner manufacturer if 
available. If no instructions are furnished, use the following 
recommendations.

The Q179 has two mounting ears at the burner and two 
mounting holes in the bracket (see Fig. 2). If the mounting 
holes in the bracket are used, it may be necessary to break off 
one of the mounting ears so that the bracket fits flush with the 
burner.All models are supplied with a factory-installed 1/4 inch 
compression coupling inlet fitting. When a fitting is used, 
remove the compression nut and install the new fitting.

Use a pressure regulator in the line supplying the Q179 pilot. 
Adjust the regulator for a maximum inlet gas pressure of eight 
inches water column. The minimum inlet gas pressure must be 
two inches water column to assure reliable lightoff of the main 
flame.

Install the pilot assembly so the pilot flame has full contact with 
the gas stream from the main burner heads or jets. Mount the 
flame electrode just inside the junction of the main and pilot 
flame to prove both flames. Mount the pilot so that it fires in the 
same direction as the draft at the mounting point, rather than 
where the draft is at right angles to flame travel. Keep the pilot 
burner below or behind the main burner so that the burner 
frame and refractory will help protect the pilot from radiant 
heat. Locating the pilot in the secondary air stream will also 
provide considerable cooling. The primary air adjustment must 
be accessible and outside the high temperature area.

—

Where ambient temperatures exceed those specified in 
Fig. 3.

—

Where excessive draft turbulence can deflect the pilot 
flame away from the main burner or flame electrode.

—

Where the ignition electrode is within arcing distance of 
any metal other than the pilot burner head.

—

Where the flame electrode contacts any metal part of 
the installation.

—

Where the flame electrode is closer than one inch from 
a radiant refractory.
