Verify combustion chamber
Chamber dimensions and construction
• If retrofi tting the burner to an appliance, install the burner in accordance
with the appliance instruction manual, when available. If no specifi c
application data is available from the appliance manufacturer, read the
guidelines below to check whether the burner is likely to work acceptably
in the application.
• Illustrations A to E in Figure 1 show different chamber confi gurations, with
and without refractory linings. The chamber dimensions listed in Table 3
depend on whether the chamber is lined or water-backed, as shown.
• Do not attempt to fi re the burner in a chamber with dimensions smaller
than shown in Table 3 unless the application has been specifi cally tested
and listed by the appliance manufacturer and/or Carlin.
• Chambers with dimensions larger than shown in Table 3 should not have
much effect on combustion/performance.
General guidelines
• Clean all appliance fl ues and heating surfaces thoroughly, removing all
soot and scale.
• Seal all joints and gaps using furnace cement to prevent excess air
infi ltration.
Read the WARNING on page 26 before handling or applying
ceramic fi ber materials.
Using chamber linings
• When using refractory liners or lightweight chambers, use insulating-type
refractory rated 2600°F minimum, or as specifi ed by the appliance manu-
facturer.
• You must install a target wall liner if fl ame length is close to the length of
the chamber.
• Use a fl oor liner when possible. The fl oor liner will improve fi ring in most
applications. Extend fl oor liner 3 to 4 inches up the side walls.
• Target wall liners — Extend target wall liners at least 3 to 4 inches above
the center of the fl ame corbel the top 1½ to 2½ inches deep.
• Use preformed chamber liners when available. Lining the fl oor and target
wall water-backed combustion chambers with lightweight insulating refrac-
tory will accomplish the same.
• When converting coal-fi red units, install a combustion chamber in the ashpit
area, or fi ll the ashpit with sand up to 2 inches above the “mud ring” of the
boiler (fi ring through the door). Install a lightweight refractory liner on the
target wall as in Figure 2D.
