Chamber Wall
Make sure the chamber wall  is strong enough to support
the weight of the burner . If necessary, reinforce the
mounting area.
Burner Mounting
Mount burner to chamber wall using four (4) customer supplied
nuts and lock washers.
1. Make sure that you install the burner mounting gasket, item
, between the burner mounting flange and the chamber
wall.
2. Make sure that the gasket does not leak.
Insulate the Firing Tube
Chamber
insulation
To insure that radiated heat doesn't reach the exterior of
the chamber, insulate the combustion tube over the length
contained within the chamber wall, filling any clearance
completely. If the firing tube extends beyond the chamber wall
thickness, do not insulate the exposed end of the tube.
Burner Piping
The burner is factory assembled and shipped as ordered.
Note:
If it is necessary to redirect piping, be sure the:
•
ratio regulator spring column  is pointing up.
•
arrow on the ratio regulator points in the direction of
gas flow.
•
•
regulator and the burner .
Supply Piping
Inlet pressure to the ratio regulator (if supplied) should be at
least 15"w.c. (37.5 mbar). It should not exceed the maximum
pressure rating of the ratio regulator.
•
Locate the valve train close to the burner. The gas must
reach the burner during the fixed trial for ignition.
•
Sufficiently size shut off valves in the valve train.
•
Make sure piping is large enough.
•
Minimize piping elbows.
Pipe Connections
•
Installation of a pipe union in the gas line is recommended
to simplify burner removal.
Bracket
•
Use of flexible pipe is optional.
Note:
Flexible pipe causes higher pressure drops than standard
pipe. Consider this when sizing your gas lines.
